NUCLEAR REGULATORY COMMISSION
Biweekly Notice; Applications and Amendments to Facility
Operating Licenses Involving No Significant Hazards Considerations
Note: The publication date for this notice will change from
every other Wednesday to every other Tuesday, effective January 8,
2002. The notice will contain the same information and will continue
to be published biweekly.
I. Background
Pursuant to Public Law 97-415, the U.S. Nuclear Regulatory
Commission (the Commission or NRC staff) is publishing this regular
biweekly notice. Public Law 97-415 revised section 189 of the Atomic
Energy Act of 1954, as amended (the Act), to require the Commission to
publish notice of any amendments issued, or proposed to be issued,
under a new provision of section 189 of the Act. This provision grants
the Commission the authority to issue and make immediately effective
any amendment to an operating license upon a determination by the
Commission that such amendment involves no significant hazards
consideration, notwithstanding the pendency before the Commission of a
request for a hearing from any person.
This biweekly notice includes all notices of amendments issued, or
proposed to be issued from October 9, 2001 through October 19, 2001.
The last biweekly notice was published on October 17, 2001 (66 FR
52794).
Notice of Consideration of Issuance of Amendments to Facility Operating
Licenses, Proposed No Significant Hazards Consideration Determination,
and Opportunity for a Hearing
The Commission has made a proposed determination that the following
amendment requests involve no significant hazards consideration. Under
the Commission's regulations in 10 CFR 50.92, this means that operation
of the facility in accordance with the proposed amendment would not (1)
involve a significant increase in the probability or consequences of an
accident previously evaluated; or (2) create the possibility of a new
or different kind of accident from any accident previously evaluated;
or (3) involve a significant reduction in a margin of safety. The basis
for this proposed determination for each amendment request is shown
below.
The Commission is seeking public comments on this proposed
determination. Any comments received
[[Page 55008]]
within 30 days after the date of publication of this notice will be
considered in making any final determination.
Normally, the Commission will not issue the amendment until the
expiration of the 30-day notice period. However, should circumstances
change during the notice period such that failure to act in a timely
way would result, for example, in derating or shutdown of the facility,
the Commission may issue the license amendment before the expiration of
the 30-day notice period, provided that its final determination is that
the amendment involves no significant hazards consideration. The final
determination will consider all public and State comments received
before action is taken. Should the Commission take this action, it will
publish in the Federal Register a notice of issuance and provide for
opportunity for a hearing after issuance. The Commission expects that
the need to take this action will occur very infrequently.
Written comments may be submitted by mail to the Chief, Rules and
Directives Branch, Division of Administrative Services, Office of
Administration, U.S. Nuclear Regulatory Commission, Washington, DC
20555-0001, and should cite the publication date and page number of
this Federal Register notice. Written comments may also be delivered to
Room 6D22, Two White Flint North, 11545 Rockville Pike, Rockville,
Maryland from 7:30 a.m. to 4:15 p.m. Federal workdays. Copies of
written comments received may be examined at the NRC Public Document
Room, located at One White Flint North, 11555 Rockville Pike (first
floor), Rockville, Maryland. The filing of requests for a hearing and
petitions for leave to intervene is discussed below.
By November 30, 2001, the licensee may file a request for a hearing
with respect to issuance of the amendment to the subject facility
operating license and any person whose interest may be affected by this
proceeding and who wishes to participate as a party in the proceeding
must file a written request for a hearing and a petition for leave to
intervene. Requests for a hearing and a petition for leave to intervene
shall be filed in accordance with the Commission's ``Rules of Practice
for Domestic Licensing Proceedings'' in 10 CFR part 2. Interested
persons should consult a current copy of 10 CFR 2.714, which is
available at the NRC's Public Document Room, located at One White Flint
North, 11555 Rockville Pike (first floor), Rockville, Maryland 20852.
Publicly available records will be accessible electronically from the
Agencywide Documents Access and Management Systems (ADAMS) Public
Electronic Reading Room on the internet at the NRC web site, http://www.nrc.gov/NRC/ADAMS/index.html. If a request for a hearing or
petition for leave to intervene is filed by the above date, the
Commission or an Atomic Safety and Licensing Board, designated by the
Commission or by the Chairman of the Atomic Safety and Licensing Board
Panel, will rule on the request and/or petition; and the Secretary or
the designated Atomic Safety and Licensing Board will issue a notice of
a hearing or an appropriate order.
As required by 10 CFR 2.714, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following factors: (1) The nature of the petitioner's right under the
Act to be made a party to the proceeding; (2) the nature and extent of
the petitioner's property, financial, or other interest in the
proceeding; and (3) the possible effect of any order which may be
entered in the proceeding on the petitioner's interest. The petition
should also identify the specific aspect(s) of the subject matter of
the proceeding as to which petitioner wishes to intervene. Any person
who has filed a petition for leave to intervene or who has been
admitted as a party may amend the petition without requesting leave of
the Board up to 15 days prior to the first prehearing conference
scheduled in the proceeding, but such an amended petition must satisfy
the specificity requirements described above.
Not later than 15 days prior to the first prehearing conference
scheduled in the proceeding, a petitioner shall file a supplement to
the petition to intervene which must include a list of the contentions
which are sought to be litigated in the matter. Each contention must
consist of a specific statement of the issue of law or fact to be
raised or controverted. In addition, the petitioner shall provide a
brief explanation of the bases of the contention and a concise
statement of the alleged facts or expert opinion which support the
contention and on which the petitioner intends to rely in proving the
contention at the hearing. The petitioner must also provide references
to those specific sources and documents of which the petitioner is
aware and on which the petitioner intends to rely to establish those
facts or expert opinion. Petitioner must provide sufficient information
to show that a genuine dispute exists with the applicant on a material
issue of law or fact. Contentions shall be limited to matters within
the scope of the amendment under consideration. The contention must be
one which, if proven, would entitle the petitioner to relief. A
petitioner who fails to file such a supplement which satisfies these
requirements with respect to at least one contention will not be
permitted to participate as a party.
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing, including the opportunity to present evidence and cross-
examine witnesses.
If a hearing is requested, the Commission will make a final
determination on the issue of no significant hazards consideration. The
final determination will serve to decide when the hearing is held.
If the final determination is that the amendment request involves
no significant hazards consideration, the Commission may issue the
amendment and make it immediately effective, notwithstanding the
request for a hearing. Any hearing held would take place after issuance
of the amendment.
If the final determination is that the amendment request involves a
significant hazards consideration, any hearing held would take place
before the issuance of any amendment.
A request for a hearing or a petition for leave to intervene must
be filed with the Secretary of the Commission, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001, Attention: Rulemaking and
Adjudications Branch, or may be delivered to the Commission's Public
Document Room, located at One White Flint North, 11555 Rockville Pike
(first floor), Rockville, Maryland 20852, by the above date. A copy of
the petition should also be sent to the Office of the General Counsel,
U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, and to
the attorney for the licensee.
Nontimely filings of petitions for leave to intervene, amended
petitions, supplemental petitions and/or requests for a hearing will
not be entertained absent a determination by the Commission, the
presiding officer or the Atomic Safety and Licensing Board that the
petition and/or request should be granted based upon a balancing of
factors specified in 10 CFR 2.714(a)(1)(i)-(v) and 2.714(d).

Unit 1, DeWitt County, Illinois
Docket No. 50-219, Oyster Creek Generating Station, Ocean County, New
Jersey
Docket Nos. 50-289, Three Mile Island Nuclear Station, Unit 1, Dauphin
County, Pennsylvania
Date of amendment request: August 1, 2001.
Description of amendment request: The requested changes to the
technical specifications (TSs) propose to revise requirements that have
been superceded based on licensed operator training programs being
accredited by the Institute for Nuclear Power Operations (INPO),
promulgation of the revised 10 CFR part 55, Operators' Licenses, and
adoption of a systems approach to training as required by 10 CFR
50.120, Training and qualification of nuclear power plant personnel.
The same changes were requested by Exelon Generation Company, LLC
(Exelon) for Braidwood Station, Units 1 and 2; Byron Station, Units 1
and 2; Dresden Nuclear Power Station, Units 2 and 3; LaSalle County
Station, Units 1 and 2; Limerick Generating Station, Units 1 and 2;
Peach Bottom Atomic Power Station, Units 2 and 3; and Quad Cities
Nuclear Power Station, Units 1 and 2. The proposed no significant
hazards consideration for those plants is published elsewhere in the
Federal Register under Exelon Generation Company, LLC.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration. The staff has reviewed the licensee's analysis against
the standards of 10 CFR 50.92(c). The NRC staff's review is presented
below:
1. The proposed change does not involve a significant increase in
the probability or consequences of an accident previously evaluated.
There will be no changes to the procedures by which the operators
operate the plants. There will be no changes to the systems,
structures, or components in the plants.
Based on the above, these proposed changes do not involve a
significant increase in the probability or consequences of an accident
previously evaluated.
2. The proposed change does not create the possibility of a new or
different kind of accident previously evaluated.
There will be no changes to the procedures by which the operators
operate the plants. There will be no changes to the systems,
structures, or components in the plants.
Therefore, the proposed changes will not create the possibility of
a new or different kind of accident previously evaluated.
3. The proposed change does not involve a significant reduction in
a margin of safety.
There will be no change in the plants' systems, structures, or
components, nor in the way in which they will be operated as a result
of the proposed changes. Therefore, the proposed changes will not
involve a significant reduction in a margin of safety.
Based on this review, it appears that the three standards of 10 CFR
50.92(c) are satisfied. Therefore, the NRC staff proposes to determine
that the requested amendments involve no significant hazards
consideration.

Dominion Nuclear Connecticut, Inc., Docket No. 50-336, Millstone
Nuclear Power Station, Unit No. 2, New London County, Connecticut
Date of amendment request: July 31, 2001.
Description of amendment request: The proposed amendment deletes
requirements from the Technical Specifications (and, as applicable,
other elements of the licensing bases) to maintain a Post Accident
Sampling System (PASS). Licensees were generally required to implement
PASS upgrades as described in NUREG-0737, ``Clarification of TMI [Three
Mile Island] Action Plan Requirements,'' and Regulatory Guide 1.97,
``Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess
Plant and Environs Conditions During and Following an Accident.''
Implementation of these upgrades was an outcome of the lessons learned
from the accident that occurred at TMI, Unit 2. Requirements related to
PASS were imposed by Order for many facilities and were added to or
included in the technical specifications (TS) for nuclear power
reactors currently licensed to operate. Lessons learned and
improvements implemented over the last 20 years have shown that the
information obtained from PASS can be readily obtained through other
means or is of little use in the assessment and mitigation of accident
conditions.
The NRC staff issued a notice of opportunity for comment in the
Federal Register on August 11, 2000 (65 FR 49271) on possible
amendments to eliminate PASS, including a model safety evaluation and
model no significant hazards consideration (NSHC) determination, using
the consolidated line item improvement process. The NRC staff
subsequently issued a notice of availability of the models for
referencing in license amendment applications in the Federal Register
on October 31, 2000 (65 FR 65018). The licensee affirmed the
applicability of the following NSHC determination in its application
dated July 31, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident
Previously Evaluated.
The PASS was originally designed to perform many sampling and
analysis functions. These functions were designed and intended to be
used in post accident situations and were put into place as a result
of the TMI-2 accident. The specific intent of the PASS was to
provide a system that has the capability to obtain and analyze
samples of plant fluids containing potentially high levels of
radioactivity, without exceeding plant personnel radiation exposure
limits. Analytical results of these samples would be used largely
for verification purposes in aiding the plant staff in assessing the
extent of core damage and subsequent offsite radiological dose
projections. The system was not intended to and does not serve a
function for preventing accidents and its elimination would not
affect the probability of accidents previously evaluated.
In the 20 years since the TMI-2 accident and the consequential
promulgation of post accident sampling requirements, operating
experience has demonstrated that a PASS provides little actual
benefit to post accident mitigation. Past experience has indicated
that there exists in-plant instrumentation and methodologies
available in lieu of a PASS for collecting and assimilating
information
[[Page 55010]]
needed to assess core damage following an accident. Furthermore, the
implementation of Severe Accident Management Guidance (SAMG)
emphasizes accident management strategies based on in-plant
instruments. These strategies provide guidance to the plant staff
for mitigation and recovery from a severe accident. Based on current
severe accident management strategies and guidelines, it is
determined that the PASS provides little benefit to the plant staff
in coping with an accident.
The regulatory requirements for the PASS can be eliminated
without degrading the plant emergency response. The emergency
response, in this sense, refers to the methodologies used in
ascertaining the condition of the reactor core, mitigating the
consequences of an accident, assessing and projecting offsite
releases of radioactivity, and establishing protective action
recommendations to be communicated to offsite authorities. The
elimination of the PASS will not prevent an accident management
strategy that meets the initial intent of the post-TMI-2 accident
guidance through the use of the SAMGs, the emergency plan (EP), the
emergency operating procedures (EOP), and site survey monitoring
that support modification of emergency plan protective action
recommendations (PARs).
Therefore, the elimination of PASS requirements from Technical
Specifications (TS) (and other elements of the licensing bases) does
not involve a significant increase in the consequences of any
accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of
a New or Different Kind of Accident from any Previously Evaluated.
The elimination of PASS related requirements will not result in
any failure mode not previously analyzed. The PASS was intended to
allow for verification of the extent of reactor core damage and also
to provide an input to offsite dose projection calculations. The
PASS is not considered an accident precursor, nor does its existence
or elimination have any adverse impact on the pre-accident state of
the reactor core or post accident confinement of radionuclides
within the containment building.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety.
The elimination of the PASS, in light of existing plant
equipment, instrumentation, procedures, and programs that provide
effective mitigation of and recovery from reactor accidents, results
in a neutral impact to the margin of safety. Methodologies that are
not reliant on PASS are designed to provide rapid assessment of
current reactor core conditions and the direction of degradation
while effectively responding to the event in order to mitigate the
consequences of the accident. The use of a PASS is redundant and
does not provide quick recognition of core events or rapid response
to events in progress. The intent of the requirements established as
a result of the TMI-2 accident can be adequately met without
reliance on a PASS.
Therefore, this change does not involve a significant reduction
in the margin of safety. Based upon the reasoning presented above
and the previous discussion of the amendment request, the requested
change does not involve a significant hazards consideration.
The NRC staff proposes to determine that the amendment request
involves no significant hazards consideration.

Dominion Nuclear Connecticut, Inc., Docket No. 50-336, Millstone
Nuclear Power Station, Unit No. 2, New London County, Connecticut
Date of amendment request: August 27, 2001.
Description of amendment request: The proposed amendment would
revise the Technical Specification action and surveillance requirements
associated with the containment air lock and expand the current
guidance provided to address inoperable air lock components.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed Technical Specification changes to revise the
action and surveillance requirements associated with the containment
air lock will not cause an accident to occur and will not result in
any change in the operation of the associated accident mitigation
equipment. The containment air lock is not an accident initiator.
The proposed changes will not revise the operability requirements
(e.g., leakage limits) for the containment air lock. Proper
operation of the containment air lock will still be verified. As a
result, the design basis accidents will remain the same postulated
events described in the Millstone Unit No. 2 Final Safety Analysis
Report, and the consequences of the design basis accidents will
remain the same. Therefore, the proposed changes will not increase
the probability or consequences of an accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
The proposed changes to the Technical Specifications do not
impact any system or component that could cause an accident. The
proposed changes will not alter the plant configuration (no new or
different type of equipment will be installed) or require any
unusual operator actions. The proposed changes will not alter the
way any structure, system, or component functions, and will not
significantly alter the manner in which the plant is operated. The
response of the plant and the operators following an accident will
not be different. In addition, the proposed changes do not introduce
any new failure modes. Therefore, the proposed changes will not
create the possibility of a new or different kind of accident from
any accident previously analyzed.
3. Involve a significant reduction in a margin of safety.
The proposed Technical Specification changes to revise the
action and surveillance requirements associated with the containment
air lock will not cause an accident to occur and will not result in
any change in the operation of the associated accident mitigation
equipment. The operability requirements for the containment air lock
have not been changed. The containment air lock will continue to
function as assumed in the safety analysis. In addition, the
proposed changes will not adversely affect equipment design or
operation, and there are no changes being made to the Technical
Specification required safety limits or safety system settings that
would adversely affect plant safety. Therefore, the proposed changes
will not result in a reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Date of amendment request: August 28, 2001.
Description of amendment request: The proposed amendment would
revise the Technical Specifications by removing the surveillance
requirement that verifies the automatic opening features of the safety
injection tank outlet isolation valves.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed Technical Specification change to remove the
surveillance
[[Page 55011]]
requirement that verifies the automatic opening features of the
safety injection tank outlet isolation valves will not cause an
accident to occur since the safety injection tanks and associated
isolation valves are not accident initiators. In addition, the
proposed change will not alter the operation of the associated
accident mitigation equipment. The operability requirement for the
safety injection tank outlet isolation valves to be deenergized open
when the safety injection tanks are required to be operable will not
be affected, and outlet isolation valve position will still be
verified periodically. As a result, the design basis accidents will
remain the same postulated events described in the Millstone Unit
No. 2 Final Safety Analysis Report, and the consequences of the
design basis accidents will remain the same. Therefore, the proposed
change will not increase the probability or consequences of an
accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
The proposed Technical Specification change does not impact any
system or component that could cause an accident. The proposed
change will not alter the plant configuration (no new or different
type of equipment will be installed) or require any unusual operator
actions. The proposed change will not alter the way any structure,
system, or component functions, and will not significantly alter the
manner in which the plant is operated. The response of the plant and
the operators following an accident will not be different. In
addition, the proposed change does not introduce any new failure
modes. Therefore, the proposed change will not create the
possibility of a new or different kind of accident from any accident
previously analyzed.
3. Involve a significant reduction in a margin of safety.
The proposed Technical Specification change to remove the
surveillance requirement that verifies the automatic opening
features of the safety injection tank outlet isolation valves will
not cause an accident to occur and will not result in any change in
the operation of the associated accident mitigation equipment. The
proposed change will not revise the operability requirement for the
safety injection tank outlet isolation valves to be deenergized open
when the safety injection tanks are required to be operable. The
safety injection tanks will continue to be able to mitigate the
design basis accidents as assumed in the safety analysis. In
addition, the proposed change will not adversely affect equipment
design or operation, and there are no changes being made to the
Technical Specification required safety limits or safety system
settings that would adversely affect plant safety. Therefore, the
proposed change will not result in a reduction in a margin of
safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

423, Millstone Nuclear Power Station, Unit Nos. 2 and 3, New London
County, Connecticut
Date of amendment request: June 4, 2001.
Description of amendment request: The proposed amendment modifies
the Millstone Nuclear Power Station, Unit No. 2 (MP2) and Unit No. 3
(MP3) Technical Specifications (TSs) to relocate selected MP2 and MP3
technical specifications related to the reactor coolant system to the
respective Technical Requirements Manual (TRM), with the exception of
MP3 Technical Specification section 4.4.10, which will be relocated to
section 6 of MP3's TS. The Bases of the affected TSs will be modified
to address the proposed changes.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration. The NRC staff reviewed the licensee's analysis against
the standards of 10 CFR 50.92(c). The NRC staff's analysis, which is
based on the representation made by the licensee in the June 4, 2001,
application, is presented below:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed requirements remain the same except that the
requirements will be relocated to the TRM. Since the proposed
requirements are the same, this proposed change will not increase the
probability or consequences of an accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
Since the requirements remain the same, these proposed changes do
not alter the way any system, structure, or component functions and do
not alter the manner in which the plant is operated. The proposed
changes do not introduce any new failure modes. Therefore, the proposed
changes will not create the possibility of a new or different kind of
accident from any accident previously evaluated.
3. Involve a significant reduction in a margin of safety.
Since the proposed changes are solely to relocate the existing
requirements, it does not affect plant operation in any way. Therefore,
the proposed change will not result in a reduction in a margin of
safety.
Based on the NRC staff's analysis, it appears that the three
standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff
proposes to determine that the amendment request involves no
significant hazards consideration.

determined that the PASS provides little benefit to the plant staff
in coping with an accident.
The regulatory requirements for the PASS can be eliminated
without degrading the plant emergency response. The emergency
response, in this sense, refers to the methodologies used in
ascertaining the condition of the reactor core, mitigating the
consequences of an accident, assessing and projecting offsite
releases of radioactivity, and establishing protective action
recommendations to be communicated to offsite authorities. The
elimination of the PASS will not prevent an accident management
strategy that meets the initial intent of the post-TMI-2 accident
guidance through the use of the SAMGs, the emergency plan (EP), the
emergency operating procedures (EOP), and site survey monitoring
that support modification of emergency plan protective action
recommendations (PARs).
Therefore, the elimination of PASS requirements from Technical
Specifications (TS) (and other elements of the licensing bases) does
not involve a significant increase in the consequences of any
accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of
a New or Different Kind of Accident from any Previously Evaluated.
The elimination of PASS related requirements will not result in
any failure mode not previously analyzed. The PASS was intended to
allow for verification of the extent of reactor core damage and also
to provide an input to offsite dose projection calculations. The
PASS is not considered an accident precursor, nor does its existence
or elimination have any adverse impact on the pre-accident state of
the reactor core or post accident confinement of radionuclides
within the containment building.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety.
The elimination of the PASS, in light of existing plant
equipment, instrumentation, procedures, and programs that provide
effective mitigation of and recovery from reactor accidents, results
in a neutral impact to the margin of safety. Methodologies that are
not reliant on PASS are designed to provide rapid assessment of
current reactor core conditions and the direction of degradation
while effectively responding to the event in order to mitigate the
consequences of the accident. The use of a PASS is redundant and
does not provide quick recognition of core events or rapid response
to events in progress. The intent of the requirements established as
a result of the TMI-2 accident can be adequately met without
reliance on a PASS.
Therefore, this change does not involve a significant reduction
in the margin of safety.
Based upon the reasoning presented above and the previous
discussion of the amendment request, the requested change does not
involve a significant hazards consideration.
The NRC staff proposes to determine that the amendment request
involves no significant hazards consideration.

Entergy Nuclear Operations, Docket No. 50-247, Indian Point Nuclear
Generating Unit No. 2, Westchester County, New York
Date of amendment request: September 20, 2001.
Description of amendment request: The proposed amendment would
revise Technical Specification (TS) 3.8, ``Refueling, Fuel Storage and
Operations with the Reactor Vessel Head Bolts Less Than Fully
Tensioned,'' TS Table 4.1-2, ``Frequencies for Sampling Tests,'' and TS
Section 5.4, ``Fuel Storage,'' to allow the credit for soluble boron in
the criticality analysis of the spent fuel pit (SFP). The revisions
also incorporate changes to the SFP rack layout by dividing it into
sub-regions and specifying requirements for fuel assembly burnup and
soluble boron concentration for various loading configurations in these
sub-regions.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Operation of the facility in accordance with the proposed
amendment would not involve a significant increase in the
probability of occurrence or consequences of an accident previously
evaluated.
Current TS contain minimum requirements for the SFP boron
concentration. The actual boron concentration in the SFP has been
maintained at a higher value. The proposed changes to the TS
establish new boron concentration requirements for the SFP water
that are consistent with the new criticality analysis. Since soluble
boron has already been maintained in the SFP water and is currently
required by the TS, the implementation of this new requirement will
have no effect on the normal SFP operations and maintenance.
The presence of an increased requirement for soluble boron in
the SFP water does not increase the probability of a fuel assembly
drop accident in the SFP. The handling of the fuel assemblies in the
SFP has always been performed in borated water. The criticality
analysis shows the consequences of a fuel assembly drop accident in
the SFP are not affected when considering the presence of soluble
boron since the rack keff remains 0.95.
Fuel assembly placement will continue to be controlled in
accordance with approved fuel handling procedures and will be in
accordance with TS spent fuel rack storage configuration
limitations. The proposed SFP storage configuration limitations will
be more complex but will be similar to those previously approved.
Therefore, the new limitations will not significantly increase the
probability of accident occurrence. There is no increase in the
consequences of the accidental misloading of spent fuel assemblies
into the spent fuel racks since the criticality analysis
demonstrates that the SFP keff will remain
0.95 following an accidental misloading.
There is no increase in the probability of the loss of normal
cooling to the spent fuel pit water when considering the presence of
soluble boron in the pit water for subcriticality control since a
high concentration of soluble boron has always been maintained in
the SFP water.
Soluble boron requirements for mitigating reactivity effects due
to increased pool temperatures are adequately met by the proposed
increase in minimum TS soluble boron concentration. A negligible
increase in
[[Page 55013]]
the probability of a criticality accident due to increased pool
temperature exists with the proposed TS changes, as the minimum
soluble boron concentration will not change. The positive reactivity
introduced as a result of the higher TS boron concentration effect
on moderator reactivity coefficient will be sufficiently mitigated
by the substantial margin to the amount actually required to
maintain keff 0.95.
Decreased fuel temperatures will increase the water density in
the SFP, therefore increasing the thermal neutron flux, possibly
causing an increase in reactivity. This density increase will
increase the differential worth of the soluble boron but the excess
soluble boron in the SFP is more than sufficient to offset any
reactivity increase introduced by a temperature decrease.
Therefore, the proposed changes do not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Operation of the facility in accordance with the proposed
amendment would not create the possibility of a new or different
kind of accident from any accident previously evaluated.
Spent fuel handling accidents are not new or different types of
accidents, they have been analyzed for the UFSAR [Updated Final
Safety Analysis Report] and in Criticality Analysis reports
associated with License Amendment 150 up to the nominal 5.0 \w\/o
\235\ U [weight percent uranium-235] that is assumed for the
proposed change.
A dilution of the SFP soluble boron has always been a
possibility. However the boron dilution event previously had no
consequences since boron was not previously credited. With the
proposed TS, credit is taken for soluble boron. So a boron dilution
has been evaluated as a possible new accident. The evaluation
concluded a boron dilution accident was not credible, that processes
were in place to detect and mitigate the possible events, and that,
even if the SFP boron concentration was diluted to zero, criticality
would not occur. Therefore, there would be no additional hazards if
this request were approved.
There is no other change in the plant configuration or equipment
design.
Therefore, the proposed change does not create a new accident
initiator or precursor, or create the possibility of a new or
different kind of accident from any accident previously evaluated.
3. Operation of the facility in accordance with the proposed
amendment would not involve a significant reduction in [a] margin of
safety.
The TS changes proposed by this LAR [license amendment request]
and the resulting spent fuel storage operation limits will provide
adequate safety margin to ensure that the stored fuel assembly array
will always remain subcritical. These limits are based on the plant
specific criticality analysis and boron dilution analysis. The
proposed TS changes rely upon known and predictable reactivity
effects to ensure required criticality margins in the SFP.
While the criticality analysis utilizes credit for soluble
boron, storage configurations have been defined using 95/95
keff calculations to ensure the spent fuel rack
keff will be 1.0 with no soluble boron. Soluble boron
credit is used to offset uncertainties, tolerances, and off-normal
conditions and to provide subcritical margin such that the SFP
keff is maintained 0.95.
The loss of substantial amounts of soluble boron from the SFP,
which could lead to keff exceeding 0.95, has been
evaluated and shown to be not credible. An evaluation has been
performed that shows that the dilution of the SFP boron
concentration from 2000 ppm [parts per million] to 786 ppm is not
credible. Also the spent fuel rack keff will remain 1.0
with the SFP flooded with unborated water. These safety analyses
demonstrate a level of safety comparable to the conservative
criticality analysis approved for License Amendment 150 and show
that the requirements of 10CFR50.68 are met.
The reactivity credit for additional poisons in the spent and
fresh fuel assemblies increases the margin of safety in the SFP. No
credit is taken for Boraflex in certain regions, when in reality
some residual Boraflex does remain in these regions. In regions that
do take credit for Boraflex, the amount of credit is conservative.
These conservatisms add an increased safety margin. Predictions of
the effective neutron multiplication factors have shown that, under
the worst of scenarios, the SFP remains subcritical when
conservative credit for future expected loss of Boraflex poison
plates is considered.
The analysis show that the level of safety required by
10CFR50.68 is achieved for the IP2 [Indian Point 2] SFP with the
proposed TS.
Therefore, operation of the facility in accordance with the
proposed amendment would not involve a significant reduction in [a]
margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Nuclear Operations, Docket No. 50-247, Indian Point Nuclear
Generating Unit No. 2, Westchester County, New York
Date of amendment request: September 20, 2001.
Description of amendment request: The proposed amendment deletes
requirements from the Technical Specifications (TSs) (and, as
applicable, other elements of the licensing bases) to maintain a Post
Accident Sampling System (PASS). Licensees were generally required to
implement PASS upgrades as described in NUREG-0737, ``Clarification of
TMI [Three Mile Island] Action Plan Requirements,'' and Regulatory
Guide 1.97, ``Instrumentation for Light-Water-Cooled Nuclear Power
Plants to Assess Plant and Environs Conditions During and Following an
Accident.'' Implementation of these upgrades was an outcome of the
lessons learned from the accident that occurred at TMI, Unit 2.
Requirements related to PASS were imposed by Order for many facilities
and were added to or included in the TSs for nuclear power reactors
currently licensed to operate. Lessons learned and improvements
implemented over the last 20 years have shown that the information
obtained from PASS can be readily obtained through other means or is of
little use in the assessment and mitigation of accident conditions.
The NRC staff issued a notice of opportunity for comment in the
Federal Register on August 11, 2000 (65 FR 49271) on possible
amendments to eliminate PASS, including a model safety evaluation and
model no significant hazards consideration (NSHC) determination, using
the consolidated line item improvement process. The NRC staff
subsequently issued a notice of availability of the models for
referencing in license amendment applications in the Federal Register
on October 31, 2000 (65 FR 65018). The licensee affirmed the
applicability of the following NSHC determination in its application
dated September 20, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident
Previously Evaluated.
The PASS was originally designed to perform many sampling and
analysis functions. These functions were designed and intended to be
used in post accident situations and were put into place as a result
of the TMI-2 [Three Mile Island 2] accident. The specific intent of
the PASS was to provide a system that has the capability to obtain
and analyze samples of plant fluids containing potentially high
levels of radioactivity, without exceeding plant personnel radiation
exposure limits. Analytical results of these samples would be used
largely for verification purposes in aiding the plant staff in
assessing the extent of core damage and subsequent offsite
radiological dose projections. The system was not intended to and
does not serve a function for preventing accidents and its
elimination would not affect the probability of accidents previously
evaluated.
[[Page 55014]]
In the 20 years since the TMI-2 accident and the consequential
promulgation of post accident sampling requirements, operating
experience has demonstrated that a PASS provides little actual
benefit to post accident mitigation. Past experience has indicated
that there exists in-plant instrumentation and methodologies
available in lieu of a PASS for collecting and assimilating
information needed to assess core damage following an accident.
Furthermore, the implementation of Severe Accident Management
Guidance (SAMG) emphasizes accident management strategies based on
in-plant instruments. These strategies provide guidance to the plant
staff for mitigation and recovery from a severe accident. Based on
current severe accident management strategies and guidelines, it is
determined that the PASS provides little benefit to the plant staff
in coping with an accident.
The regulatory requirements for the PASS can be eliminated
without degrading the plant emergency response. The emergency
response, in this sense, refers to the methodologies used in
ascertaining the condition of the reactor core, mitigating the
consequences of an accident, assessing and projecting offsite
releases of radioactivity, and establishing protective action
recommendations to be communicated to offsite authorities. The
elimination of the PASS will not prevent an accident management
strategy that meets the initial intent of the post-TMI-2 accident
guidance through the use of the SAMGs, the emergency plan (EP), the
emergency operating procedures (EOP), and site survey monitoring
that support modification of emergency plan protective action
recommendations (PARs).
Therefore, the elimination of PASS requirements from Technical
Specifications (TS) (and other elements of the licensing bases) does
not involve a significant increase in the consequences of any
accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of
a New or Different Kind of Accident from any Previously Evaluated.
The elimination of PASS related requirements will not result in
any failure mode not previously analyzed. The PASS was intended to
allow for verification of the extent of reactor core damage and also
to provide an input to offsite dose projection calculations. The
PASS is not considered an accident precursor, nor does its existence
or elimination have any adverse impact on the pre-accident state of
the reactor core or post accident confinement of radionuclides
within the containment building.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in [a] Margin of Safety.
The elimination of the PASS, in light of existing plant
equipment, instrumentation, procedures, and programs that provide
effective mitigation of and recovery from reactor accidents, results
in a neutral impact to the margin of safety. Methodologies that are
not reliant on PASS are designed to provide rapid assessment of
current reactor core conditions and the direction of degradation
while effectively responding to the event in order to mitigate the
consequences of the accident. The use of a PASS is redundant and
does not provide quick recognition of core events or rapid response
to events in progress. The intent of the requirements established as
a result of the TMI-2 accident can be adequately met without
reliance on a PASS.
Therefore, this change does not involve a significant reduction
in [a] margin of safety.
Based upon the reasoning presented above and the previous
discussion of the amendment request, the requested change does not
involve a significant hazards consideration.
The NRC staff proposes to determine that the amendment request
involves no significant hazards consideration.

Entergy Nuclear Operations, Docket No. 50-247, Indian Point Nuclear
Generating Unit No. 2, Westchester County, New York
Date of amendment request: September 20, 2001.
Description of amendment request: The proposed amendment would
allow the one-time extension of the intervals for selected Technical
Specification (TS) surveillance requirements (SRs) to enable the tests
to be performed during the next refueling outage starting no later than
November 19, 2002. Specifically, the surveillance interval would be
extended for certain SRs associated with the volume control tank (VCT),
residual heat removal system (RHR) , emergency diesel generators
(EDGs), and shock suppressors (snubbers). In addition, the proposed
amendment would: (1) Correct the channel functional test interval in
Items 3 and 4 of TS Table 4.10-4 and Items 4 and 5 of Table 4-10-4, (2)
delete alternate inspection requirements for the steam generator
snubbers, and (3) remove the reference to a prior one-time extension of
checks, calibrations and tests for certain instrument channels in TS
Table 4.1-1 that is no longer applicable.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
(1) Does the proposed license amendment involve a significant
increase in the probability or consequences of an accident
previously evaluated?
There is no change to the design, function, or capability of any
plant structure, system, or component as a result of the proposed
surveillance interval extensions. Hence there is no change in the
probability of occurrence of an accident previously evaluated.
The proposed surveillance interval extensions do not affect the
ability of any plant structure, system, or component to mitigate the
consequences of any accident previously evaluated. The surveillance
interval extensions do not alter or prevent the ability of the
affected structures, systems, and components to perform their
intended functions.
[VCT]
A statistical analysis of channel uncertainty for a proposed 31
month operating cycle has been performed. It confirms that the
channel drift for the proposed 31 month interval is bounded by the
existing drift allowance used in the current uncertainty
calculations. Therefore, there is no expected decrease in
reliability for the VCT level channel for the proposed 31 month
operating cycle. Since there is no expected decrease in the
reliability of the VCT level channels, the design safety functions
of the VCT are not affected.
[RHR]
Since the past test data supports the integrity of the system
and an extended standby period is not expected to affect any
potential leak path, there is a reasonable expectation that the RHR
and Safety Injection systems will continue to perform their intended
safety functions without excessive leakage. It is concluded that a
one-time extension of less than one month for the leakage test
surveillance intervals will have minimal impact on the system
reliability.
[EDG]
The identified anomalies with valve and filter operation for EDG
23 were evaluated and corrected and are not indicative of any
inability of the machine to meet performance requirements. The
anomalous adjustment affecting movement of the fuel control lever
arm for EDG 22 was properly evaluated and eliminated as evidenced by
subsequent successful testing. Therefore, the historical data
together with the positive verification of the adequacy of
corrective actions for previous test failures demonstrate that the
EDGs have met the required performance criteria. Therefore the
ability of the EDGs to mitigate accidents is not affected by this
proposed change.
Failure of an EDG cannot, of itself, initiate an accident.
[Snubbers]
The TS functional testing program requires a sampling program
that provides a 95% confidence level that 90-100% of the snubbers
operate within acceptance limits. For each snubber failing the
functional test an additional sample lot must be selected and tested
to assure that the required confidence level is maintained. The past
functional test history with very few functional test failures
provides assurance that an extension in the surveillance will not
[[Page 55015]]
result in increased snubber failures. In all cases, the functional
test failures were thoroughly analyzed and appropriate action was
taken to prevent recurrence. Subsequent testing resulted in all
snubbers meeting their design requirements.
The operability of snubbers is not affected by the deletion of
the allowance to separately group steam generator snubbers for the
purposes of determining inspection intervals.
Therefore, operation of the facility in accordance with the
proposed amendment would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
(2) Does the proposed license amendment create the possibility
of a new or different kind of accident from any accident previously
evaluated?
The proposed changes do not involve any physical design change
or operational change to any plant system, structure or component.
Thus a new failure mode is not introduced. Therefore, the proposed
changes do not create a new accident initiator or precursor, or
create the possibility of a new or different kind of accident from
any accident previously evaluated.
[VCT]
The proposed change does not involve the addition of any new or
different type of equipment, nor does it involve operating equipment
required for safe operation of the facility in a manner that is
different from that addressed in the Updated Final Safety Analysis
Report (UFSAR). The proposed change in the surveillance interval has
been evaluated to have a negligible effect on the reliability of the
existing instruments.
[RHR]
The proposed change does not involve the addition of any new or
different type of equipment. Nor does it involve operating equipment
required for safe operation of the facility in a manner that is
different from that addressed in the UFSAR.
[EDG]
The proposed change does not involve the addition of any new or
different type of equipment, nor does it involve operating equipment
required for safe operation of the facility in a manner that is
different from that addressed in the UFSAR. Also, the increased
surveillance interval (one-time only) will not adversely affect the
reliability of the EDGs.
[Snubbers]
The proposed license amendment does not create the possibility
of a new or different kind of accident from any previously
evaluated. The proposed change does not involve the addition of any
new or different type of equipment, nor does it involve operating
equipment required for safe operation of the facility in a manner
that is different from that addressed in the UFSAR. Also, the
increased surveillance interval (one-time only) will not adversely
affect the snubbers.
(3) Does the proposed amendment involve a significant reduction
in a margin of safety?
As a result of these proposed surveillance interval extensions,
there are no changes to IP2's design or to the IP2 TS safety limits,
limiting safety system settings, or limiting conditions for
operation. The only change is a change to the surveillance testing
frequency for affected structures, systems, and components.
The proposed surveillance interval extensions have been
evaluated to not significantly degrade the reliability of any
existing system, structure, or component. Therefore, testing in
accordance with the proposed test intervals continues to ensure that
the necessary quality of affected structures, systems, and
components is maintained, that IP2 operation will be within safety
limits, and that the IP2 limiting conditions for operation will be
met.
The proposed surveillance interval extensions do not adversely
affect the ability of any IP2 structures, systems, or components to
function when required to mitigate any accident or licensing basis
event.
[VCT]
The proposed change in surveillance interval resulting from an
increased operating cycle will not result in a channel statistical
allowance that impacts any TS limit or any UFSAR requirement.
Protective functions will continue to occur so that safety analysis
limits are not exceeded.
Based on past rest results, the one-time extension of nine days
does not involve a significant reduction in a margin of safety.
[RHR]
There is minimal risk that a surveillance interval extension of
less than one month will increase leakage in the piping systems
under review beyond the TS limits or that the system performance
will be influenced. Past test data indicate that there was no impact
on the margin imposed by the TS.
[EDG]
The functional test history indicates the functional test
failures were the result of actions independent of actual EDG load
performance. Apart from these anomalous actions, the record does not
indicate a potential for failure to meet performance criteria. In
all cases, the functional test failures were thoroughly analyzed and
appropriate actions were taken to prevent recurrence.
Subsequent testing resulted in the EDG meeting its design
requirements.
There is no reduction of margin indicated by the surveillance
testing. The proposed change for a one-time extension of the test
interval does not adversely affect the performance of any safety
related system, component or structure and does not result in
increased severity of any of the accidents considered in the UFSAR.
Surveillance test results indicate no trend toward margin reduction.
[Snubbers]
The objective of the functional test is to provide a 95%
confidence level that 90-100% of the snubbers operate within the
specified acceptance limits. The review of past test history
indicates that this objective was met at the time of the testing.
There are no identified trends that would suggest that the same
success rate would not be maintained over the requested extension
period. The proposed license amendment does not involve a
significant reduction in a margin of safety. The proposed change for
a one-time extension of the test interval does not adversely affect
the performance of any safety related system, component or structure
and does not result in increased severity of any of the accidents
considered in the UFSAR.
Therefore, the one-time extension of less than one month for the
functional tests does not involve a significant reduction in a
margin of safety.
The proposed deletion of the allowance to separately group steam
generator snubbers for the purpose of determining inspection
intervals does not affect the effectiveness of the surveillance
requirements. The steam generator snubbers will still be inspected
at the interval required by the TS.
Therefore, operation of the facility in accordance with the
proposed amendment would not involve a significant reduction in the
margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Operations, Inc., Docket No. 50-368, Arkansas Nuclear One, Unit
No. 2, Pope County, Arkansas
Date of amendment request: October 2, 2001.
Description of amendment request: The proposed amendment would
revise Technical Specification (TS) Table 3.3-4, ``Engineered Safety
Feature Actuation System Instrumentation Trip Values,'' Functional Unit
7.b, ``Loss of Power, 460 volt Emergency Bus Undervoltage,'' by
changing the referenced bus from the 460 volt (V) bus to the 480 V bus,
by removing the trip setpoint, and by slightly increasing the range of
allowable values for the degraded voltage setting and its associated
time delay.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
Criterion 1--Does Not Involve a Significant Increase in the
Probability or Consequences of an Accident Previously Evaluated.
The two degraded voltage protection relays that are provided on
each of the 480 V safety buses act to mitigate the consequences of
an
[[Page 55016]]
accident by detecting a sustained undervoltage condition, isolating
the safety buses from offsite power, and starting the associated
emergency diesel generator (EDG). This safety function is unchanged
by the proposed allowable voltage setting revisions. The revised
settings for the degraded voltage protection relays will continue to
provide the safety function of protecting the associated Class 1E
equipment from the effects of a low voltage condition. The time
delays remain within those assumed in the ANO-2 [Arkansas Nuclear
One, Unit 2] safety analyses. Additionally, the revised allowable
voltage settings will not result in any unnecessary isolation from
the off-site power sources. The relocation of trip setpoint values
to station surveillance procedures allows operational flexibility to
account for additional margins, drifts, or uncertainties while
ensuring that the relays are set to actuate within the acceptable
range of allowable values denoted in the TSs. Since the proposed
change does not adversely impact the mitigating function of the
relays, the consequences of an accident previously evaluated remains
unchanged.
The ANO-2 technical specifications will continue to require the
480 V bus degraded voltage functions to be surveillance tested at
their present frequency without changing the modes in which the
surveillance is required or the modes of applicability for these
components. The technical specifications will continue to require
the same actions as currently exist for the inoperability of one or
more of the 480 V bus degraded voltage relays.
Therefore, this change does not involve a significant increase
in the probability or consequences of any accident previously
evaluated.
Criterion 2--Does Not Create the Possibility of a New or Different
Kind of Accident from any Previously Evaluated.
The proposed change introduces no new modes of plant operation
or new plant configuration that could lead to a new or different
kind of accident from any previously evaluated being introduced. The
480 V bus degraded voltage relays are required to operate upon
detection of a sustained undervoltage condition to protect the Class
1E components from damage from low voltage by initiating transfer of
the 4160 V safety bus power source to the EDG. This safety function
remains unchanged by the proposed allowable voltage setting
revisions, and the proposed values continue to provide the required
actions consistent with the ANO-2 safety analysis.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--Does Not Involve a Significant Reduction in the Margin
of Safety.
The two degraded voltage relays located on each 480 V safety bus
are provided to detect sustained undervoltage, isolate the safety
buses, and start the EDGs. This safety function remains unchanged by
the proposed revisions to the allowable values. The proposed changes
to the allowable values for the degraded voltage relays incorporate
channel uncertainties and calibration tolerances, while fully
meeting their required safety functions of degraded voltage
protection without resulting in undesired tripping of the offsite
power source.
The slightly higher range of allowable values for the degraded
voltage settings allows enhanced protection of the Class 1E
components, but does not result in undesired tripping of the offsite
power source for the analyzed grid minimum normal condition. In
addition, the slight increase in the range of allowable values for
the degraded voltage time delay remains well within the assumption
of the accident analysis.
Therefore, this change does not involve a significant reduction
in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

The accident of concern related to the proposed change is the
fuel handling accident. This accident assumes a dropped fuel
assembly. One of the assumptions made in the analysis is that fuel
movement is delayed at least 100 hours after shutdown to allow for
radioactive decay of the fission product inventory. TS 3.9.3.a
provides this restriction. The analysis does not assume any further
delay in fuel movement following the initial 100-hour decay period.
The relocation of TS 3.9.3.b will not impact this assumption.
Therefore, this change does not involve a significant increase
in the probability or consequences of any accident previously
evaluated.
2. Will operation of the facility in accordance with this
proposed change create the possibility of a new or different kind of
accident from any accident previously evaluated.
The proposed change relocates TS 3.9.3.b to the TRM. There are
no changes to the design or operation of the facility proposed.
Thus, there are no new or different kinds of accidents created. SFP
cooling capability and the heat load generated by the movement of
fuel into the SFP will continue to be evaluated under 10 CFR 50.59.
The SFP cooling system includes two cooling pumps and one heat
exchanger. In addition, several systems are available for makeup
when needed. Under postulated accident conditions, when no pool
cooling systems are operational, the maximum temperature at the
inlet to the cells is assumed to be equal to the saturation
temperature at atmospheric pressure or 212F [Fahrenheit] (allowed to
boil). The proposed change does not increase the possibility of a
complete loss of pool cooling.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
3. Will operation of the facility in accordance with this
proposed change involve a significant reduction in a margin of
safety?
The proposed change relocates TS 3.9.3.b to the TRM. Following
relocation, any future changes to TRM 3.9.3.b will be assessed under
the guidance of 10 CFR 50.59. The ANO [Arkansas Nuclear One] 50.59
process will provide an evaluation to ensure heat loads transferred
will be within the cooling capacity of the service water system.
Analyses will continue to demonstrate that even in the event of a
loss of SFP cooling, the maximum temperature in the pool is such
that design limits associated with assuring the integrity of the
fuel cladding are satisfied.
Therefore, this change does not involve a significant reduction
in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Operations, Inc., Docket No. 50-368, Arkansas Nuclear One, Unit
No. 2, Pope County, Arkansas
Date of amendment request: October 2, 2001.
Description of amendment request: The proposed amendment would
change the technical specification definitions of response time for the
reactor trip system (RTS) and for engineered safety features (ESFs) to
allow use of either an allocated or a
[[Page 55017]]
measured response time for select sensors in these two systems.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Will operation of the facility in accordance with this
proposed change involve a significant increase in the probability or
consequences of an accident previously evaluated?
Response time testing is not an initiator of any previously
evaluated accident. The proposed change to the definition of RTS and
ESF response time allows substitution of an allocated response time
for selected sensors in lieu of measuring the sensor response time.
The allocated response times adequately represent the response time
of the components such that the safety systems utilizing these
components will continue to perform their accident mitigation
function as assumed in the safety analysis. Response time testing
for the non-sensor portions of the channels will continue to use a
series of sequential or overlapping test measurements.
Therefore, this change does not involve a significant increase
in the probability or consequences of any accident previously
evaluated.
2. Will operation of the facility in accordance with this
proposed change create the possibility of a new or different kind of
accident from any accident previously evaluated?
The proposed change does not involve a physical change to the
plant. Modifications will not be made to existing components nor
will any new or different types of equipment be installed. The
proposed change modifies the definitions for RTS and ESF response
time and allows the substitution of an allocated response time in
lieu of measured sensor response time for selected sensors. The
response time assumed in the accident analysis for the non-sensor
portions of the channels will continue to be verified using a series
of sequential or overlapping test measurements. Appropriate actions
will be taken to ensure overall channel response time remains within
the times specified in the accident analysis.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
3. Will operation of the facility in accordance with this
proposed change involve a significant reduction in a margin of
safety?
The proposed change modifies the definitions of RTS and ESF
response time to allow a substitution of an allocated response time
for selected sensors in lieu of measuring the response time. The
allocated time adequately represents the actual measured time for
the associated sensors. The overall response time of each channel
will continue to be measured using a series of sequential,
overlapping or entire channel measurements to ensure the components
actuated by each channel perform their accident mitigation function
within the response time assumed in the safety analysis.
Therefore, this change does not involve a significant reduction
in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Operations Inc., Docket No. 50-382, Waterford Steam Electric
Station, Unit 3, St. Charles Parish, Louisiana
Date of amendment request: September 21, 2001.
Description of amendment request: Entergy Operations, Inc.
(Entergy, the licensee) is requesting approval of changes to the
Waterford Steam Electric Station, Unit 3, Operating License and
Technical Specifications associated with an increase in the licensed
power level. The changes involve a proposed increase in the power level
from 3,390 Megawatts thermal (MWt) to 3,441 MWt. These changes result
from increased feedwater flow measurement accuracy to be achieved by
utilizing high accuracy ultrasonic flow measurement instrumentation.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Will operation of the facility in accordance with this
proposed change involve a significant increase in the probability or
consequences of an accident previously evaluated?
The comprehensive analytical efforts performed to support the
proposed change included a review of the Nuclear Steam Supply System
(NSSS) systems and components that could be affected by this change.
All systems and components will function as designed, and the
applicable performance requirements have been evaluated and found to
be acceptable.
The primary loop components (reactor vessel, reactor internals,
control element drive mechanisms, loop piping and supports, reactor
coolant pumps, steam generators, and pressurizer) continue to comply
with their applicable structural limits and will continue to perform
their intended design functions. Thus, there is no increase in the
probability of a structural failure of these components. The Leak
Before Break analysis conclusions remain valid, and thus the
limiting break sizes determined in this analysis remain bounding.
All of the NSSS will still perform the intended design functions
during normal and accident conditions. The auxiliary systems and
components continue to meet their applicable structural limits and
will continue to perform their intended design functions. Thus,
there is no increase in the probability of a structural failure of
these components. All of the NSSS and Balance of Plant (BOP)
interface systems will continue to perform their intended design
functions. The main steam safety valves (MSSVs) will provide
adequate relief capacity to maintain the steam generator pressures
within design limits. The atmospheric dump valves and steam bypass
valves meet design sizing requirements at the uprated power level.
The current Loss of Coolant Accident (LOCA) hydraulic forcing
functions are still bounding for the proposed 1.5 percent increase
in power.
Because the integrity of the plant will not be affected by
operation at the uprated condition, it is concluded that all
structures, systems, and components required to mitigate a transient
remain capable of fulfilling their intended functions. The reduced
uncertainty in the flow input to the power calorimetric measurement
allows the current safety analyses to be used, without change, to
support operation at a core power of 3,441 megawatts thermal (MWt).
As such, all Updated Final Safety Analysis Report (UFSAR) Chapter 15
accident analyses continue to demonstrate compliance with the
relevant event acceptance criteria. Those analyses performed to
assess the effects of mass and energy releases remain valid. The
source terms used to assess radiological consequences have been
reviewed and determined to either bound operation at the 1.5 percent
uprated condition, or new analyses were performed to verify all
acceptance criteria continue to be met.
Therefore, this change does not involve a significant increase
in the probability or consequences of any accident previously
evaluated.
2. Will operation of the facility in accordance with this
proposed change create the possibility of a new or different kind of
accident from any accident previously evaluated?
No new accident scenarios, failure mechanisms, or single
failures are introduced as a result of the proposed changes. The new
installation of the LEFM [leading edge flow meter] CheckPlus system
has been analyzed, and failures of this system will have no effect
on any safety-related system or any systems, structures or
components required for transient mitigation. All systems,
structures, and components previously required for the mitigation of
a transient remain capable of fulfilling their intended design
functions. The proposed changes have no adverse effects on any
safety-related system or component and do not challenge the
performance or integrity of any safety related system.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
3. Will operation of the facility in accordance with this
proposed change
[[Page 55018]]
involve a significant reduction in a margin of safety?
Operation at the uprated power condition does not involve a
significant reduction in a margin of safety. Analyses of the primary
fission product barriers have concluded that all relevant design
criteria remain satisfied, both from the standpoint of the integrity
of the primary fission product barrier and from the standpoint of
compliance with the required acceptance criteria.
Therefore, this change does not involve a significant reduction
in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Date of amendment request: August 1, 2001.
Description of amendment request: The requested changes to the
technical specifications (TSs) propose to revise requirements that have
been superceded based on licensed operator training programs being
accredited by the Institute for Nuclear Power Operations (INPO),
promulgation of the revised 10 CFR part 55, Operators' Licenses, and
adoption of a systems approach to training as required by 10 CFR
50.120, Training and qualification of nuclear power plant personnel.
The same changes were requested by AmerGen Energy Company, LLC
(AmerGen) for the Clinton Power Station, Oyster Creek, and Three Mile
Island, Unit 1. The proposed no significant hazards consideration for
those plants is published elsewhere in the Federal Register under
AmerGen.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration. The staff has reviewed the licensee's analysis against
the standards of 10 CFR 50.92(c). The NRC staff's review is presented
below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
There will be no changes to the procedures by which the
operators operate the plants. There will be no changes to the
systems, structures, or components in the plants.
Based on the above, these proposed changes do not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. The proposed change does not create the possibility of a new
or different kind of accident previously evaluated.
There will be no changes to the procedures by which the
operators operate the plants. There will be no changes to the
systems, structures, or components in the plants.
Therefore, the proposed changes will not create the possibility
of a new or different kind of accident previously evaluated.
3. The proposed change does not involve a significant reduction
in a margin of safety.
There will be no change in the plants' systems, structures, or
components, nor in the way in which they will be operated as a
result of the proposed changes. Therefore, the proposed changes will
not involve a significant reduction in a margin of safety.
Based on this review, it appears that the three standards of 10 CFR
50.92(c) are satisfied. Therefore, the NRC staff proposes to determine
that the requested amendments involve no significant hazards
consideration.

and 2, Will County, Illinois
Date of amendment request: September 21, 2001.
Description of amendment request: The proposed amendment deletes
requirements from the Technical Specifications (and, as applicable,
other elements of the licensing bases) to maintain a Post Accident
Sampling System (PASS). Licensees were generally required to implement
PASS upgrades as described in NUREG-0737, ``Clarification of TMI [Three
Mile Island] Action Plan Requirements,'' and Regulatory Guide 1.97,
``Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess
Plant and Environs Conditions During and Following an Accident.''
Implementation of these upgrades was an outcome of the lessons learned
from the accident that occurred at TMI, Unit 2. Requirements related to
PASS were imposed by Order for many facilities and were added to or
included in the technical specifications (TS) for nuclear power
reactors currently licensed to operate. Lessons learned and
improvements implemented over the last 20 years have shown that the
information obtained from PASS can be readily obtained through other
means or is of little use in the assessment and mitigation of accident
conditions.
The NRC staff issued a notice of opportunity for comment in the
Federal Register on August 11, 2000 (65 FR 49271) on possible
amendments to eliminate PASS, including a model safety evaluation and
model no significant hazards consideration (NSHC) determination, using
the consolidated line item improvement process. The NRC staff
subsequently issued a notice of availability of the models for
referencing in license amendment applications in the Federal Register
on October 31, 2000 (65 FR 65018). The licensee affirmed the
applicability of the following NSHC determination in its application
dated September 21, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident
Previously Evaluated.
The PASS was originally designed to perform many sampling and
analysis functions. These functions were designed and intended to be
used in post accident situations and were put into place as a result
of the TMI-2 accident. The specific intent of the PASS was to
provide a system that has the capability to obtain and analyze
samples of plant fluids containing potentially high levels of
radioactivity, without exceeding plant personnel radiation exposure
limits. Analytical results of these samples would be used largely
for verification purposes in aiding the plant staff in assessing the
extent of core damage and subsequent offsite
[[Page 55019]]
radiological dose projections. The system was not intended to and
does not serve a function for preventing accidents and its
elimination would not affect the probability of accidents previously
evaluated.
In the 20 years since the TMI-2 accident and the consequential
promulgation of post accident sampling requirements, operating
experience has demonstrated that a PASS provides little actual
benefit to post accident mitigation. Past experience has indicated
that there exists in-plant instrumentation and methodologies
available in lieu of a PASS for collecting and assimilating
information needed to assess core damage following an accident.
Furthermore, the implementation of Severe Accident Management
Guidance (SAMG) emphasizes accident management strategies based on
in-plant instruments. These strategies provide guidance to the plant
staff for mitigation and recovery from a severe accident. Based on
current severe accident management strategies and guidelines, it is
determined that the PASS provides little benefit to the plant staff
in coping with an accident.
The regulatory requirements for the PASS can be eliminated
without degrading the plant emergency response. The emergency
response, in this sense, refers to the methodologies used in
ascertaining the condition of the reactor core, mitigating the
consequences of an accident, assessing and projecting offsite
releases of radioactivity, and establishing protective action
recommendations to be communicated to offsite authorities. The
elimination of the PASS will not prevent an accident management
strategy that meets the initial intent of the post-TMI-2 accident
guidance through the use of the SAMGs, the emergency plan (EP), the
emergency operating procedures (EOP), and site survey monitoring
that support modification of emergency plan protective action
recommendations (PARs).
Therefore, the elimination of PASS requirements from Technical
Specifications (TS) (and other elements of the licensing bases) does
not involve a significant increase in the consequences of any
accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility
of a New or Different Kind of Accident From Any Previously
Evaluated.
The elimination of PASS related requirements will not result in
any failure mode not previously analyzed. The PASS was intended to
allow for verification of the extent of reactor core damage and also
to provide an input to offsite dose projection calculations. The
PASS is not considered an accident precursor, nor does its existence
or elimination have any adverse impact on the pre-accident state of
the reactor core or post accident confinement of radionuclides
within the containment building.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety
The elimination of the PASS, in light of existing plant
equipment, instrumentation, procedures, and programs that provide
effective mitigation of and recovery from reactor accidents, results
in a neutral impact to the margin of safety. Methodologies that are
not reliant on PASS are designed to provide rapid assessment of
current reactor core conditions and the direction of degradation
while effectively responding to the event in order to mitigate the
consequences of the accident. The use of a PASS is redundant and
does not provide quick recognition of core events or rapid response
to events in progress. The intent of the requirements established as
a result of the TMI-2 accident can be adequately met without
reliance on a PASS.
Therefore, this change does not involve a significant reduction
in the margin of safety.
Based upon the reasoning presented above and the previous
discussion of the amendment request, the requested change does not
involve a significant hazards consideration.
The NRC staff proposes to determine that the amendment request
involves no significant hazards consideration.

FirstEnergy Nuclear Operating Company, et al., Docket No. 50-412,
Beaver Valley Power Station, Unit 2, Beaver County, Pennsylvania
Date of amendment request: June 28, 2001.
Description of amendment request: The proposed amendment would
revise the technical specification (TS) 3.1.1.4 upper limit for the
moderator temperature coefficient (MTC) from 0 x 10-4
change in reactivity per degree Fahrenheit (``k/k/ deg.F) to +0.2 x
10-4 ``k/k/ deg.F for power levels up to 70 percent of rated
thermal power (RTP), and ramping linearly to 0 x 10-4 ``k/
k/ deg.F from 70 percent to 100 percent RTP. The proposed change is
needed to address future core designs with higher energy requirements,
associated with plant operation at higher capacity factors.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the change involve a significant increase in the
probability or consequences of an accident previously evaluated?
No. The proposed change from a[n] MTC of 0 x 10-4
``k/k/ deg.F to a positive moderator temperature coefficient (PMTC)
of +0.2 x 10-4 ``k/k/ deg.F does not introduce an
initiator of any design basis accident or event. The proposed change
does not adversely affect accident initiators or precursors nor
alter the configuration of the facility or the manner in which the
plant is maintained. Thus, the proposed change does not involve a
significant increase in the probability of an accident previously
evaluated.
The proposed change to a PMTC does not alter or prevent the
ability of structures, systems, and components (SSCs) from
performing their intended function to mitigate the consequences of
an initiating event within the assumed acceptance limits. The
proposed change is consistent with the safety analysis assumptions
and resultant consequences. Accident analyses affected by the
proposed change have been reanalyzed and all applicable acceptance
criteria have been met. Thus, the proposed change does not involve a
significant increase in the consequences of an accident previously
evaluated.
Therefore, the proposed amendment does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the change create the possibility of a new or different
kind of accident from any accident previously evaluated?
No. The change to a PMTC does not involve a physical alteration
of the plant (i.e., no new or different type of equipment will be
installed), subsequently no new or different failure modes or
limiting single failures are created. The plant will not be operated
in a different manner due to the proposed change. All SSCs will
continue to function as currently designed. Thus, the proposed
change does not create any new or different accident scenarios.
Therefore, the proposed amendment does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. Does the change involve a significant reduction in a margin
of safety?
No. The proposed change to a PMTC does not involve revisions to
any safety limits or safety system settings that would adversely
impact plant safety. The proposed amendment does not alter the
functional capabilities assumed in a safety analysis for any SSCs
important to the mitigation and control of design bases accident
conditions within the facility.
All of the applicable acceptance criteria (i.e., preventing
reactor coolant system [RCS] or main steam system
overpressurization, maintaining the minimum departure from nucleate
boiling ratio [DNBR], preventing core uncovery, preventing fuel
temperatures from exceeding their limit, preventing clad damage, and
limiting the number of fuel rods that enter a departure from
nucleate boiling [DNB] condition) for each of the analyses affected
by the proposed change continue to be met. The conclusions of the
UFSAR remain valid. Thus, since the operating parameters and system
performance will remain within design requirements and safety
analysis assumptions, safety margin is maintained.
Therefore, the proposed amendment does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three
[[Page 55020]]
standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff
proposes to determine that the amendment request involves no
significant hazards consideration.

GPU Nuclear Inc., Docket No. 50-320, Three Mile Island Nuclear
Generating Station, Unit 2, Dauphin County, Pennsylvania
Date of amendment request: June 21, 2001.
Description of amendment request: The proposed technical
specifications change request (TSCR) No. 81 is to revise Three Mile
Island Nuclear Generating Station, Unit 2 (TMI-2) Technical
Specification (TS) Administrative Controls section that will provide
consistency with the changes to the revised 50.59 rule of Title 10 of
the Code of Federal Regulations (10 CFR) Regulations, as published in
the Federal Register on October 4, 1999 (64 FR 53582).
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
Does the change involve a significant increase in the
probability or consequences of an accident previously evaluated?
The proposed changes reflect the revised 50.59 rule, issued as a
Final Rule in October 4, 1999, and do not impact the operation of
any system or component assumed in any accident analysis. The
proposed change does not change the requirement to perform a 50.59
review when required by the Technical Specification Administrative
Controls. Based on the administrative nature of this change there
will be no direct impact on the radiological source term. Therefore,
these changes will not involve a significant increase in the
probability or consequences of an accident previously evaluated.
Does the change create the possibility of a new or different
kind of accident from any accident previously evaluated?
The proposed changes are administrative in nature and do not
involve a change to the plant design or operation. No new or
different types of equipment will be installed as a result of this
change. The proposed change is administrative in nature and makes
the language in the Technical Specification Administrative Controls
conform to the Final Rule, dated October 4, 1999, related to the 10
CFR 50.59 rule. No new accident mode or equipment failure modes are
created by these changes. Therefore, these proposed changes do not
create the possibility of a new or different kind of accident from
any accident previously evaluated.
Does the change involve a significant reduction in a margin of
safety?
The proposed change does not impact or have a direct effect on
any safety analysis assumptions. The proposed change is
administrative in nature and makes the TS Administrative Control
language conform to the Final Rule, dated October 4, 1999, related
to the 10 CFR 50.59 rule. Changes to the facility that result in
meeting the criteria of 10 CFR 50.59 will still require NRC approval
pursuant to 10 CFR 50.59.
Therefore, the proposed changes do not involve a significant
reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Niagara Mohawk Power Corporation, Docket No. 50-410, Nine Mile Point
Nuclear Station Unit No. 2, Oswego County, New York
Date of amendment request: October 5, 2001.
Description of amendment request: The licensee proposed to amend
the Technical Specifications (TSs) to change the licensing basis
requirement for establishing containment hydrogen monitoring ``within
30 minutes'' to ``within 3 hours'' of initiating emergency core cooling
following a loss-of-coolant accident (LOCA).
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration. The NRC staff has reviewed the licensee's analysis
against the three standards of 10 CFR 50.92(c). The licensee's analysis
is presented below:
1. The operation of Nine Mile Point Unit 2 in accordance with
the proposed amendment will not involve a significant increase in
the probability or consequences of an accident previously evaluated.
The Updated Safety Analysis Report (USAR) Chapter 15 accident
analyses do not require or take credit for hydrogen monitoring to be
established shortly after a loss of coolant accident (LOCA). Post-
LOCA hydrogen production occurs over a long period of time, and an
extension from 30 minutes to 3 hours for establishing hydrogen
monitoring will have a positive impact on the ability of the
operators to concentrate on their more immediate actions while
having no negative impact on containment integrity or the long-term
assessment efforts. Therefore, the proposed license amendment will
not involve a significant increase in the probability or
consequences of an accident previously evaluated.
2. The operation of Nine Mile Point Unit 2 in accordance with
the proposed amendment will not create the possibility of a new or
different kind of accident from any accident previously evaluated.
Control room operators use the containment hydrogen monitors
following a LOCA to establish hydrogen control measures should it
become necessary. The proposed license amendment would not eliminate
the requirement to establish hydrogen monitoring, but would allow it
to be delayed until those actions required to mitigate the accident
and verify proper operation of essential safety equipment have been
completed. The proposed extension maintains the requirement to
establish hydrogen monitoring well before calculated conditions
inside the containment indicate any need to initiate hydrogen
control measures. Therefore, the proposed license amendment will not
create a new or different kind of accident from any accident
previously evaluated.
3. The operation of Nine Mile Point Unit 2 in accordance with
the proposed amendment will not involve a significant reduction in a
margin of safety.
The need to establish hydrogen control measures will not be
present within the first 3 hours following a LOCA since there will
not be significant hydrogen accumulation. By extending the time
allowed to establish containment hydrogen monitoring, the operators
can remain focused on the actions necessary to mitigate the accident
before directing their attention to hydrogen control measures and
other long-term actions. The proposed extension maintains the
requirement to establish hydrogen monitoring well before calculated
conditions inside the containment indicate any need to initiate
hydrogen control measures. Therefore, the proposed license amendment
will not involve a significant reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
requested amendment involves no significant hazards consideration.

Date of amendment requests: September 13, 2001.
Description of amendment requests: The proposed license amendments
[[Page 55021]]
would revise Technical Specification (TS) 3.7.16, ``Spent Fuel Pool
Boron Concentration,'' TS 3.7.17, ``Spent Fuel Assembly Storage--Region
1/Region 2,'' and TS 4.3, ``Fuel Storage'' for DCPP Units 1 and 2, to
allow the use of credit for soluble boron in the spent fuel pool
criticality analysis.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
Response: No.
There is no increase in the probability of a fuel assembly drop
accident in the spent fuel pool (SFP) when considering the presence
of soluble boron in the SFP water for criticality control. The
handling of the fuel assemblies does not change as a result of
crediting soluble boron in the SFP.
There is no increase in the probability of the accidental
misloading of a fuel assembly into the SFP racks when considering
the presence of soluble boron in the SFP water for criticality
control. Fuel assembly placement will continue to be controlled
pursuant to approved fuel handling procedures and will be in
accordance with the Technical Specification (TS) SFP storage
configuration limitations.
There is no increase in the consequences of an accidental drop
or accidental misloading of a fuel assembly into the SFP racks
because the criticality analysis demonstrates that the pool will
remain subcritical following either event even if the pool contains
a boron concentration less than that currently specified in the TS.
The current TS limitation will ensure that an adequate SFP boron
concentration will be maintained.
There is no increase in the probability of the loss of normal
cooling to the SFP water considering the presence of soluble boron
in the pool water for subcriticality control since a high
concentration of soluble boron has always been maintained in the SFP
water.
There is no increase in the consequences of a loss of normal SFP
cooling because the 2,000 ppm boron concentration required by TS
provides significant negative reactivity to provide subcritical
margin such that the SFP keff is maintained less than or
equal to 0.95 up to boiling (212 deg.F).
Therefore, the proposed change does not involve a significant
increase in the probability or consequence of an accident previously
evaluated.
2. The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
Response: No.
Spent fuel handling accidents are not new or different types of
accidents; they have been analyzed in Section 15.5.22 of the Updated
Final Safety Analysis Report (UFSAR).
Criticality accidents in the SFP are not new or different types
of accidents; they have been analyzed in the UFSAR and in the
Criticality Analysis reports associated with the specific license
amendments for fuel enrichments up to 5.0 weight percent U-235.
Because soluble boron has always been required in the SFP water,
and is currently required by TS, credit for soluble boron will have
no effect on normal pool operation and maintenance. Crediting
soluble boron in the SFP criticality analysis will only result in
increased sampling to verify the boron concentration. This increased
sampling frequency will not create the possibility of a new or
different kind of accident.
The SFP dilution analysis demonstrates that a dilution which
could increase the rack keff to greater than 0.95 is not
a credible event. Therefore, crediting soluble boron in the SFP
criticality analysis will not result in the possibility of a new
kind of accident.
Revised specifications continue to specify the requirements for
SFP storage configurations. The only significant changes relate to
the criteria for determining the storage configuration. Because the
proposed SFP storage configuration limitations will be similar to
those currently contained in the TS, the new limitations will not
have any significant effect on normal SFP operations and maintenance
and will not create the possibility of a new or different kind of
accident. A SFP loading verification will continue to be performed
to ensure that the SFP loading configuration meets the specified
requirements.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
3. The proposed change does not involve a significant reduction
in a margin of safety.
Response: No.
The TS changes proposed by this license amendment request and
the resulting spent fuel storage limitations will provide an
adequate safety margin to ensure that the stored fuel assembly array
will always remain subcritical. Those limits are based on a plant
specific criticality analysis performed for the Diablo Canyon Units
1 and 2 SFPs that includes technically supported margins.
While the criticality analysis utilized credit for soluble
boron, storage configurations have been defined to ensure that the
spent fuel rack keff will be less than 1.0 with no
soluble boron with a 95 percent probability at a 95 percent
confidence level. Soluble boron credit is used to offset
uncertainties, tolerances and off-normal conditions, and to provide
subcritical margin such that the SFP keff is maintained
less than or equal to 0.95. Since keff is less than or
equal to 0.95, the current margin of safety is maintained.
A substantial reduction in the SFP soluble boron concentration
that could lead to exceeding a keff of 0.95 has been
evaluated and shown not to be credible.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment requests involve no significant hazards consideration.

Pacific Gas and Electric Company, Docket Nos. 50-275 and 50-323, Diablo
Canyon Nuclear Power Plant (DCPP), Unit Nos. 1 and 2, San Luis Obispo
County, California
Date of amendment requests: September 13, 2001.
Description of amendment requests: The proposed license amendments
would modify Technical Specification (TS) 5.5.9, ``Steam Generator Tube
Surveillance Program,'' to allow extension of steam generator tube W
star alternate repair criteria for DCPP Units 1 and 2, from Cycles 10
and 11 to Cycles 12 and 13.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
Of the various accidents previously evaluated, the extension of
the steam generator (SG) tube W star (W*) alternate repair criteria
(ARC) through Cycles 12 and 13 only affects the steam generator tube
rupture (SGTR) accident evaluation and the postulated steam line
break (SLB) accident evaluation. Loss-of-coolant accident (LOCA)
conditions cause a compressive axial load to act on the tube.
Therefore, since the LOCA tends to force the tube into the tubesheet
rather than pull it out, it is not a factor in this evaluation.
For the SGTR accident, the required structural margins of the SG
tubes will be maintained by the presence of the tubesheet. Tube
rupture is precluded for cracks in the Westinghouse explosive tube
expansion (WEXTEX) region due to the constraint provided by the
tubesheet. Therefore, Regulatory Guide (RG) 1.121, ``Bases for
Plugging Degraded PWR Steam Generator Tubes,'' margins against burst
are maintained for both normal and postulated accident conditions.
WCAP-14797, Revision 1, defines a length, W*, of degradation
free expanded tubing that provides the necessary resistance to tube
pullout due to the pressure induced forces (with applicable safety
factors applied). The W* length supplies the necessary resistive
force to preclude pullout loads under both normal operating and
accident conditions. The contact pressure results from the WEXTEX
expansion process, thermal
[[Page 55022]]
expansion mismatch between the tube and tubesheet and from the
differential pressure between the primary and secondary side. The
proposed changes do not affect other systems, structures,
components, or operational features. Therefore, the proposed change
results in no significant increase in the probability of the
occurrence of an SGTR or SLB accident.
The consequences of an SGTR accident are affected by the
primary-to-secondary leakage flow during the accident. Primary-to-
secondary leakage flow through a postulated broken tube is not
affected by the proposed changes since the tubesheet enhances the
tube integrity in the region of the WEXTEX expansion by precluding
tube deformation beyond its initial expanded outside diameter. The
resistance to both tube rupture and collapse is strengthened by the
tubesheet in that region. At normal operating pressures, leakage
from primary water stress corrosion cracking (PWSCC) in the W*
length is limited by both the tube-to-tubesheet crevice and the
limited crack opening permitted by the tubesheet constraint. No
leakage has been observed in any in-situ test of W* indications
identified to date. Consequently, negligible normal operating
leakage is expected from cracks within the tubesheet region.
SLB leakage is limited by leakage flow restrictions resulting
from the crack and tube-to-tubesheet contact pressures that provide
a restricted leakage path above the indications and also limit the
degree of crack face opening compared to free span indications. The
total leakage, that is, the combined leakage for all such tubes,
plus the combined leakage developed by any other ARC, are maintained
below the maximum allowable SLB leak rate limit, such that off-site
doses are maintained less than 10 CFR 100 guideline values.
Therefore, based on the above evaluation, the proposed changes
do not involve a significant increase in the probability or
consequences of an accident previously evaluated.
2. The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The proposed changes do not introduce any changes or mechanisms
that create the possibility of a new or different kind of accident.
Tube bundle integrity is expected to be maintained for all plant
conditions upon continued implementation of the W* ARC.
Axial indications left in service shall have the upper crack tip
below the top of the tubesheet (TTS) by at least the value of the
nondestructive examination (NDE) uncertainty and crack growth
allowance, such that at the end of the subsequent operating cycle
the entire crack remains below the tubesheet secondary face, thereby
minimizing the potential for free span cracking and demonstrating
that an acceptable level of risk is maintained for tubes returned to
service under W* ARC. This repair criteria is in addition to
ensuring that the upper crack tip is located below the bottom of the
WEXTEX transition by at least the NDE measurement uncertainty.
Condition monitoring will verify that all tubes returned to service
under W* ARC remain below the TTS, including an allowance for NDE
uncertainty.
These changes do not introduce any new equipment or any change
to existing equipment. No new effects on existing equipment are
created nor are any new malfunctions introduced.
Therefore, based on the above evaluation, the proposed changes
do not create the possibility of a new or different kind of accident
from any accident previously evaluated.
3. The proposed change does not involve a significant reduction
in a margin of safety.
The proposed changes maintain the required structural margins of
the SG tubes for both normal and accident conditions. RG 1.121 is
used as the basis in the development of the W* ARC for determining
that SG tube integrity considerations are maintained within
acceptable limits. RG 1.121 describes a method acceptable to the NRC
staff for meeting General Design Criteria 14, 15, 31, and 32 by
reducing the probability and consequences of an SGTR. RG 1.121
concludes that by determining the limiting safe conditions of tube
wall degradation beyond which tubes with unacceptable cracking, as
established by inservice inspection, should be removed from service
or repaired, the probability and consequences of a SGTR are reduced.
This RG uses safety factors on loads for tube-burst that are
consistent with the requirements of Section III of the ASME Code.
For primarily axially oriented cracking located within the
tubesheet, tube-burst is precluded due to the presence of the
tubesheet. WCAP-14797, Revision 1, defines a length, W*, of
degradation free expanded tubing that provides the necessary
resistance to tube pullout due to the pressure induced forces (with
applicable safety factors applied). Application of the W* ARC will
preclude unacceptable primary-to-secondary leakage during all plant
conditions. The methodology for determining leakage provides for
large margins between calculated and actual leakage values in the W*
ARC.
Plugging of the SG tubes reduces the reactor coolant flow margin
for core cooling. Continued implementation of W* ARC will result in
maintaining the margin of flow that may have otherwise been reduced
by tube plugging.
Based on the above, it is concluded that the proposed changes do
not result in a significant reduction of margin with respect to
plant safety as defined in the Final Safety Analysis Report Update
or Bases of the plant Technical Specifications.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment requests involve no significant hazards consideration.

PSEG Nuclear LLC, Docket Nos. 50-272 and 50-311, Salem Nuclear
Generating Station, Unit Nos. 1 and 2, Salem County, New Jersey
Date of amendment request: August 17, 2001.
Description of amendment request: The proposed amendments delete
requirements from the Technical Specifications (and, as applicable,
other elements of the licensing bases) to maintain a Post Accident
Sampling System (PASS). Licensees were generally required to implement
PASS upgrades as described in NUREG-0737, ``Clarification of TMI [Three
Mile Island] Action Plan Requirements,'' and Regulatory Guide 1.97,
``Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess
Plant and Environs Conditions During and Following an Accident.''
Implementation of these upgrades was an outcome of the lessons learned
from the accident that occurred at TMI, Unit 2. Requirements related to
PASS were imposed by Order for many facilities and were added to or
included in the technical specifications (TS) for nuclear power
reactors currently licensed to operate. Lessons learned and
improvements implemented over the last 20 years have shown that the
information obtained from PASS can be readily obtained through other
means or is of little use in the assessment and mitigation of accident
conditions.
The NRC staff issued a notice of opportunity for comment in the
Federal Register on August 11, 2000 (65 FR 49271) on possible
amendments to eliminate PASS, including a model safety evaluation and
model no significant hazards consideration (NSHC) determination, using
the consolidated line item improvement process. The NRC staff
subsequently issued a notice of availability of the models for
referencing in license amendment applications in the Federal Register
on October 31, 2000 (65 FR 65018). The licensee affirmed the
applicability of the following NSHC determination in its application
dated August 17, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident
Previously Evaluated.
The PASS was originally designed to perform many sampling and
analysis
[[Page 55023]]
functions. These functions were designed and intended to be used in
post accident situations and were put into place as a result of the
TMI-2 accident. The specific intent of the PASS was to provide a
system that has the capability to obtain and analyze samples of
plant fluids containing potentially high levels of radioactivity,
without exceeding plant personnel radiation exposure limits.
Analytical results of these samples would be used largely for
verification purposes in aiding the plant staff in assessing the
extent of core damage and subsequent offsite radiological dose
projections. The system was not intended to and does not serve a
function for preventing accidents and its elimination would not
affect the probability of accidents previously evaluated.
In the 20 years since the TMI-2 accident and the consequential
promulgation of post accident sampling requirements, operating
experience has demonstrated that a PASS provides little actual
benefit to post accident mitigation. Past experience has indicated
that there exists in-plant instrumentation and methodologies
available in lieu of a PASS for collecting and assimilating
information needed to assess core damage following an accident.
Furthermore, the implementation of Severe Accident Management
Guidance (SAMG) emphasizes accident management strategies based on
in-plant instruments. These strategies provide guidance to the plant
staff for mitigation and recovery from a severe accident. Based on
current severe accident management strategies and guidelines, it is
determined that the PASS provides little benefit to the plant staff
in coping with an accident.
The regulatory requirements for the PASS can be eliminated
without degrading the plant emergency response. The emergency
response, in this sense, refers to the methodologies used in
ascertaining the condition of the reactor core, mitigating the
consequences of an accident, assessing and projecting offsite
releases of radioactivity, and establishing protective action
recommendations to be communicated to offsite authorities. The
elimination of the PASS will not prevent an accident management
strategy that meets the initial intent of the post-TMI-2 accident
guidance through the use of the SAMGs, the emergency plan (EP), the
emergency operating procedures (EOP), and site survey monitoring
that support modification of emergency plan protective action
recommendations (PARs).
Therefore, the elimination of PASS requirements from Technical
Specifications (TS) (and other elements of the licensing bases) does
not involve a significant increase in the consequences of any
accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of
a New or Different Kind of Accident from any Previously Evaluated.
The elimination of PASS related requirements will not result in
any failure mode not previously analyzed. The PASS was intended to
allow for verification of the extent of reactor core damage and also
to provide an input to offsite dose projection calculations. The
PASS is not considered an accident precursor, nor does its existence
or elimination have any adverse impact on the pre-accident state of
the reactor core or post accident confinement of radionuclides
within the containment building.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety.
The elimination of the PASS, in light of existing plant
equipment, instrumentation, procedures, and programs that provide
effective mitigation of and recovery from reactor accidents, results
in a neutral impact to the margin of safety. Methodologies that are
not reliant on PASS are designed to provide rapid assessment of
current reactor core conditions and the direction of degradation
while effectively responding to the event in order to mitigate the
consequences of the accident. The use of a PASS is redundant and
does not provide quick recognition of core events or rapid response
to events in progress. The intent of the requirements established as
a result of the TMI-2 accident can be adequately met without
reliance on a PASS.
Therefore, this change does not involve a significant reduction
in the margin of safety.
Based upon the reasoning presented above and the previous
discussion of the amendment requests, the requested changes do not
involve a significant hazards consideration.
The NRC staff proposes to determine that the amendment requests
involve no significant hazards consideration.

Southern Nuclear Operating Company, Inc, Docket Nos. 50-348 and 50-364,
Joseph M. Farley Nuclear Plant, Units 1 and 2, Houston County, Alabama
Date of amendment request: May 3, 2001.
Description of amendment request: The proposed amendments would
relocate cycle-specific reactor coolant system Technical Specifications
parameters limits to the Core Operating Limits Report. Also, a
reference to the Refueling Operations Boron Concentration is added to
TS 5.6.5 to correct an omission.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
The proposed amendment is a programmatic and administrative
change that does not physically alter plant systems, nor does it
impact the performance of their functions. No new equipment is added
nor is installed equipment being changed or operated in a different
manner. Because the design of the facility and system operating
parameters are not being changed, the proposed amendment does not
involve an increase in the probability or consequences of any
accident previously evaluated.
The cycle-specific limits in the Core Operating Limits Report
(COLR) will continue to be controlled by the Farley Nuclear Plant
(FNP) programs and procedures. Each accident analysis addressed in
the Final Safety Analysis Report (FSAR) will be examined with
respect to changes in the cycle dependent parameters, which are
obtained from the use of Nuclear Regulatory Commission (NRC)
approved reload design methodologies, to ensure that the transient
evaluation of new reloads are bounded by previously accepted
analyses. This examination, which will be conducted per the
requirements of 10 CFR 50.59, will ensure that future reloads will
not involve a significant increase in the probability or
consequences of an accident previously evaluated. The safety limits
imposed in Technical Specification (TS) 2.1 are consistent with the
values stated in the FNP FSAR.
This change does not involve an increase in the probability or
consequences of any accident previously evaluated.
2. The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
Relocation of the cycle-specific parameters has no influence or
impact on, nor does it contribute in any way to the probability or
consequences of an accident. No plant equipment, function or plant
operation will be altered as a result of this proposed change. The
cycle-specific parameters are calculated using the NRC approved
methods and submitted to the NRC to allow the staff to continue to
trend the values of these limits. The TS will continue to require
operation within the core operating limits and appropriate actions
will be required if these limits are exceeded. The safety limits are
maintained in the COLR and appropriate actions will be required if
these limits are exceeded. In addition, the minimum limit for
Reactor Coolant System flow will be retained in the TS. The safety
limits imposed in TS 2.1 are consistent with the values stated in
the FNP FSAR.
This proposed amendment does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
3. The Proposed change does not involve a significant reduction
in a margin of safety.
The margin of safety is not affected by the removal of cycle-
specific core operating limits from the TS. The margin of safety
presently provided by current TS limits remains unchanged.
Appropriate measures exist to control the values of these cycle-
specific limits. The proposed amendment continues to require
operation within the core limits as obtained from NRC approved
reload design methodologies and the actions to be taken if a limit
is exceeded remain unchanged.
The development of the limits for future reloads will continue
to conform to those methods described in NRC approved documentation.
In addition, each future reload will involve a 10 CFR 50.59
evaluation to assure that operation of the unit within the cycle-
specific limits will not involve a significant reduction in the
margin of safety.
The proposed changes to relocate cycle specific parameter limits
to the COLRs will not affect plant design or system operating
parameters, there is no detrimental impact on any equipment design
parameters, and the plant will continue to operate within prescribed
limits. The safety limits imposed in TS 2.1 are consistent with the
values stated in the FNP FSAR.
This proposed change does not involve a significant reduction in
the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are

The proposed change to Surveillance Requirement (SR) 3.4.14.1
clarifies that the requirement to test Reactor Coolant System (RCS)
Pressure Isolation Valves (PIVs) following valve actuation due to
automatic or manual action or flow through the valve does not apply
to PIVs in the Residual Heat Removal (RHR) flow path. This resolves
a source of potential confusion and ensures that the testing
requirements are implemented consistent with the historical
licensing basis for Farley and the Improved Technical Specification
conversion NRC Safety Evaluation Report. The valves will continue to
be tested for back leakage every 18 months. The proposed change does
not affect the consequences of a previously analyzed accident since
the magnitude and duration of analyzed events are not impacted by
this change. Thus, the consequences of a previously evaluated
accident are unchanged.
Therefore, the proposed TS change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. The proposed changes do not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The proposed change involves no change to the physical plant. It
allows for a clarification to the testing requirements to ensure
that the historical licensing basis for Farley is maintained. These
valves are tested every 18 months to ensure that the back leakage is
within acceptable limits. This testing will continue. These changes
do not impact the function of the valves.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any accident previously
evaluated.
3. The proposed changes do not involve a significant reduction
in a margin of safety.
The physical plant is unaffected by this change. The proposed
change does not impact accident offsite dose, containment pressure
or temperature, emergency core cooling system (ECCS) or reactor
protection system (RPS) settings or any other parameter that could
affect a margin of safety. The clarification of the testing
requirements ensures that future testing is consistent with the
historical licensing basis for Farley.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Virginia Electric and Power Company, Docket Nos. 50-338 and 50-339,
North Anna Power Station, Units No. 1 and No. 2, Louisa County,
Virginia
Date of amendment request: September 10, 2001.
Description of amendment request: The proposed amendment deletes
requirements from the Technical Specifications (and, as applicable,
other elements of the licensing bases) to maintain a Post Accident
Sampling System (PASS). Licensees were generally required to implement
PASS upgrades as described in NUREG-0737, ``Clarification of TMI [Three
Mile Island] Action Plan Requirements,'' and Regulatory Guide 1.97,
``Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess
Plant and Environs Conditions During and Following an Accident.''
Implementation of these upgrades was an outcome of the lessons learned
from the accident that occurred at TMI, Unit 2. Requirements related to
PASS were imposed by Order for many facilities and were added to or
included in the technical specifications (TS) for nuclear power
reactors currently licensed to operate. Lessons learned and
improvements implemented over the last 20 years have shown that the
information obtained from PASS can be readily obtained through other
means or is of little use in the assessment and mitigation of accident
conditions.
The NRC staff issued a notice of opportunity for comment in the
Federal Register on August 11, 2000 (65 FR 49271) on possible
amendments to eliminate PASS, including a model safety evaluation and
model no significant hazards consideration (NSHC) determination, using
the consolidated line item improvement process. The NRC staff
subsequently issued a notice of availability of the models for
referencing in license amendment applications in the Federal Register
on October 31, 2000 (65 FR 65018). The licensee affirmed the
applicability of the following NSHC determination in its application
dated September 10, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident
Previously Evaluated.
The PASS was originally designed to perform many sampling and
analysis functions. These functions were designed and intended to be
used in post accident situations and were put into place as a result
of the TMI-2 accident. The specific intent of the PASS was to
provide a system that has the capability to obtain and analyze
samples of plant fluids containing potentially high levels of
radioactivity, without exceeding plant personnel radiation exposure
limits. Analytical results of these samples would be used largely
for verification purposes in aiding the plant staff in assessing the
extent of core damage and subsequent offsite radiological dose
projections. The system was not intended to and does not serve a
function for preventing accidents and its elimination would not
affect the probability of accidents previously evaluated.
In the 20 years since the TMI-2 accident and the consequential
promulgation of post accident sampling requirements, operating
experience has demonstrated that a PASS provides little actual
benefit to post accident mitigation. Past experience has indicated
that there exists in-plant instrumentation and methodologies
available in lieu of a PASS for collecting and assimilating
information needed to assess core damage following an accident.
Furthermore, the implementation of Severe Accident Management
Guidance (SAMG) emphasizes accident management strategies based on
in-plant instruments. These strategies provide guidance to the plant
staff for mitigation and recovery from a severe accident. Based on
current severe accident management strategies and guidelines, it is
determined that the PASS provides little benefit to the plant staff
in coping with an accident.
[[Page 55026]]
The regulatory requirements for the PASS can be eliminated
without degrading the plant emergency response. The emergency
response, in this sense, refers to the methodologies used in
ascertaining the condition of the reactor core, mitigating the
consequences of an accident, assessing and projecting offsite
releases of radioactivity, and establishing protective action
recommendations to be communicated to offsite authorities. The
elimination of the PASS will not prevent an accident management
strategy that meets the initial intent of the post-TMI-2 accident
guidance through the use of the SAMGs, the emergency plan (EP), the
emergency operating procedures (EOP), and site survey monitoring
that support modification of emergency plan protective action
recommendations (PARs).
Therefore, the elimination of PASS requirements from Technical
Specifications (TS) (and other elements of the licensing bases) does
not involve a significant increase in the consequences of any
accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of
a New or Different Kind of Accident from any Previously Evaluated.
The elimination of PASS related requirements will not result in
any failure mode not previously analyzed. The PASS was intended to
allow for verification of the extent of reactor core damage and also
to provide an input to offsite dose projection calculations. The
PASS is not considered an accident precursor, nor does its existence
or elimination have any adverse impact on the pre-accident state of
the reactor core or post accident confinement of radionuclides
within the containment building.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety.
The elimination of the PASS, in light of existing plant
equipment, instrumentation, procedures, and programs that provide
effective mitigation of and recovery from reactor accidents, results
in a neutral impact to the margin of safety. Methodologies that are
not reliant on PASS are designed to provide rapid assessment of
current reactor core conditions and the direction of degradation
while effectively responding to the event in order to mitigate the
consequences of the accident. The use of a PASS is redundant and
does not provide quick recognition of core events or rapid response
to events in progress. The intent of the requirements established as
a result of the TMI-2 accident can be adequately met without
reliance on a PASS.
Therefore, this change does not involve a significant reduction
in the margin of safety.
Based upon the reasoning presented above and the previous
discussion of the amendment request, the requested change does not
involve a significant hazards consideration.
The NRC staff proposes to determine that the amendment request
involves no significant hazards consideration.
