NUCLEAR REGULATORY COMMISSION

Biweekly Notice; Applications and Amendments to Facility
Operating Licenses Involving No Significant Hazards Considerations

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, 2000, through October 20, 2000.
The last biweekly notice was published on October 18, 2000.

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 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
Review and Directives Branch, Division of Administration Services,
Office of Administration, U.S. Nuclear Regulatory

[[Page 65338]]

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's Public Document Room, the Gelman Building, 2120 L Street, NW.,
Washington, DC through September 22, 2000. The NRC has relocated its
Public Document Room to the NRC's headquarters building. Effective
September 26, 2000, documents may be examined at the NRC's Public
Document Room, located at One White Flint North, 11555 Rockville Pike
(first floor), Rockville, Maryland 20852. The filing of requests for a
hearing and petitions for leave to intervene is discussed below.
By December 1, 2000, 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 Commission's Public Document Room, located at One
White Flint North, 11555 Rockville Pike (first floor), Rockville,
Maryland 20852. Publicly available records will be accessible and
electronically from the ADAMS Public Library component on the NRC Web
site, http://www.nrc.gov (the Electronic Reading Room). 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: Docketing and
Services Branch, or may be delivered to the Commission's Public
Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC
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).
For further details with respect to this action, see the
application for amendment which is available for public inspection at

Carolina Power & Light Company, et al., Docket No. 50-400, Shearon
Harris Nuclear Power Nuclear Power Plant, Unit 1, Wake and Chatham
Counties, North Carolina

Date of amendment request: October 4, 2000.
Description of amendment request: The proposed amendment would
revise the Technical Specifications (TS) to support the replacement of
the current Westinghouse Model D4 steam generators (SGs) with
Westinghouse Model Delta 75 replacement steam generators (RSGs), which
is planned to occur during the fall 2001 refueling outage. The proposed
changes to the TS

[[Page 65339]]

are required in part as a result of the physical differences between
the currently installed Model D4 SGs and the Model Delta 75 RSGs. The
Model Delta 75 RSGs have thermally treated alloy 690 tube material,
which has been proven through laboratory testing and operational
experience to provide increased corrosion resistance compared to the
Inconel 600 tube material in the Model D4 SGs. The licensee has
completed a comprehensive engineering review program in support of the
SG replacement. This program evaluated the difference between the
current Model D4 SGs and the Model Delta 75 RSGs in conjunction with
restoration of the original nominal reactor coolant average temperature
(Tavg) of 588.8 deg.F. The supporting analyses and evaluations were
performed to support operations with the RSGs at the current licensed
core power of 2775 MWt and also, where possible, at an uprated core
power level of 2900 MWt. This license amendment application, however,
does not include a request for a power uprate.
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 change does not affect accident initiators. The
change in RCS [reactor coolant system] volume, an input in certain
accident analyses, is acceptable since applicable acceptance
criteria continue to be met. The change to the calculated residual
heat removal (RHR) cooldown time does not adversely impact safe
shutdown and meets Standard Review Plan (SRP) requirements. The
analysis results for peak accident pressure (Pa remain
below the containment design pressure limit. Revised Technical
Specification limits, such as SG minimum water levels, have been
analytically determined based on the new SG design features to
preserve analysis assumptions. Since the proposed change has no
effect on accident initiators, the probability of design basis
events is not impacted by these analyses.
The leak rate assumed in accident analyses is conservative and
independent of the value of Pa. Since the peak calculated
accident pressure remains below the design value, the containment
function as a barrier to the release of radioactive material is not
adversely affected. Dose consequences have been analyzed with
respect to the proposed change and applicable acceptance criteria
continue to be met.
HNP [Harris Nuclear Plant] structures, systems and components,
as well as the RSGs, are designed to operate at the original
Tavg value of 588.8 deg.F. The comprehensive engineering
review performed to support SG replacement includes evaluation and
analysis results for transients and design basis accidents that meet
applicable acceptance criteria. The proposed DNB [departure from
nucleate boiling] parameter values ensure the core and reactor
coolant system do not exceed their safety limits. The trip setpoints
initiate safeguards actions that mitigate postulated accident
consequences. Since plant systems will function as designed and
performance requirements are verified to be acceptable with the
proposed changes, there are no impacts to accident initiators or
precursors. Therefore, these changes do not involve a significant
increase in the probability of an accident previously evaluated.
The RSGs are designed to minimize potential for the types of
tube degradation experienced with the OSGs [original steam
generators]. The changes to reactor core safety limits, RTS/ESFAS
[reactor trip system/engineered safety feature actuation system]
values and Tavg limit support transient and accident
analysis assumptions relating to fuel clad failure. Since SG tube
and fuel clad integrity will continue to be adequately maintained,
these barriers to release of radioactive material will perform their
required function. All dose consequences continue to meet acceptance
criteria. As a result, the changes do not involve a significant
increase in consequences of previously evaluated accidents.
The proposed change reduces Technical Specification limits on
reactor coolant activity to ensure that the dose consequences of the
proposed new SGTR [steam generator tube rupture] analysis meet
guidelines. The Technical Specification limits are not accident
initiators and the proposed change provides additional conservatism
in the limiting initial condition for RCS activity level. The change
in these limits functions only to mitigate consequences of RCS
liquid and steam release events and does not impact methods for
plant operation. Since there are no adverse impacts to initiators of
accidents previously evaluated, there is no significant increase in
the probability of such accidents.
The proposed change to the basis for thyroid dose conversion
factors is an accepted update to that used in the analysis of
record. Dose consequences for all analyses, including SGTR, remain
within allowable guidelines. Although there are increases to
previously reported dose consequences, the increase is not
significant since the results remain under the SRP acceptance
criteria.
Reducing the required time at hot standby to maintain adequate
CST [condensate storage tank] minimum volume ensures accident
mitigation capability and is not involved with accident initiation.
Conservative reactor trip setpoints during power operation with
inoperable main steam line safety valves ensure accident analysis
assumptions for maximum secondary system pressure. The proposed
setpoint changes are also unrelated to initiation of previously
evaluated accidents.
The removal of F* plugging criteria is consistent with NUREG-
0452, ``Standard Technical Specifications.'' The remaining Technical
Specification plugging criterion is based on a minimum wall
thickness due to wastage as determined by ASME [American Society of
Mechanical Engineers] Section XI. The proposed change is
conservative because operation with F* degraded tubes is eliminated.
The potential for a tube rupture is expected to be acceptably
low based on the qualification analysis and testing for the RSGs.
The proposed program for periodic in-service inspection monitors the
integrity of the SG tubing to provide reasonable assurance that
there is sufficient time to take proper and timely corrective action
if any tube degradation is detected. The deleted OSG tube inspection
requirements are not applicable to the RSG due to design
differences.
SG tube inspections are not accident initiators and the function
of the inspection program is to identify and eliminate, when
appropriate, accident precursor conditions. Because of this, the
probability of postulated accidents (e.g., SG tube rupture) is not
increased.
Since the proposed changes are either conservative (reduced RTS
setpoints, elimination of F* tube plugging criteria) or related to
mitigation of postulated accidents (hot standby time prior to
cooldown), there is no significant increase in dose consequences.
Therefore, the proposed change does 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 change does not adversely impact methods of plant
operation and new methods of plant systems operation are not
created. The impacts of SG replacement on NSSS [nuclear steam supply
system] and other plant systems, including the change in RCS volume
and other design differences, have been evaluated and design and
performance requirements continue to be met. Accordingly, no new
accident scenarios, failure mechanisms or limiting single failures
are introduced.
Changing Pa to reflect the results of current
analyses while maintaining its value below the containment design
pressure will not introduce significant or adverse changes to the
plant design basis that would create a new or different kind of
accident.
Since HNP structures, systems and components are designed for
operation at the proposed Tavg, returning to this value
following SG replacement does not introduce a new method of plant
operation. The proposed reactor core safety limits, RTS/ESFAS and
Tavg limit changes do not introduce new failure
mechanisms or limiting single failures since the values have been
shown to preserve transient and accident analysis assumptions. The
acceptable evaluation results demonstrate that the changes do not
adversely affect or challenge the performance or integrity of safety
related systems. Hence, no new accident scenarios are created.
The proposed change to specific activity limits does not modify
plant systems,

[[Page 65340]]

structures, or components or impact methods of plant operation. The
SGTR analysis that provides the basis for the change demonstrates
adequate margin to overfill based on revised emergency operating
procedures [EOPs]. Operator actions and response times have been
demonstrated to be acceptable and to satisfy analysis assumptions in
simulator exercises. The operator actions do not represent different
types of actions from those currently included in the EOPs, and are
not subject to errors that would create new failure mechanisms.
No new types of failures and no new or different accident
initiators are created. As a result, the change will not introduce
significant or adverse changes to the plant design basis that could
lead to the creation of a new or different kind of accident.
The revised thermal power restrictions imposed by [the]
Technical Specification[s] when there are inoperable main steam line
safety valves are conservative and consistent with the Technical
Specification Bases methodology. The reduction in hot standby time
to six hours continues to satisfy requirements for safe shutdown. No
new failure mechanisms or limiting single failures are introduced
and there are no adverse effects or challenges to the performance or
integrity of safety related systems.
Removing application of F* repair criteria and sleeving
methodologies from [the] Technical Specification[s] with the RSGs
does not introduce significant or adverse changes to the plant
design basis that could lead to a new or different kind of accident
being created. These requirements were needed to address design and
material conditions of the original HNP SGs that are not applicable
to the RSGs. This change does not alter the objective of SG
surveillance activities--maintaining the structural integrity of
this portion of the reactor coolant system. The surveillance
activities are performed during outages and the proposed
surveillance program is consistent with regulatory guidance. No new
failures are created.
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.
Analyses supporting the change reflect the RSG design, including
changes to primary and secondary volume and minimum water level for
adequate heat sink. Mass and energy and containment response
analyses model ESF [engineered safety features] systems and safety
analysis limits. The analysis results demonstrate that applicable
acceptance criteria, including DNB, RCS pressure, peak cladding
temperature, containment pressure and temperature, and dose,
continue to be met.
The calculated containment peak accident pressures result in a
value of Pa that remains below the containment design
pressure. The margin of safety during design basis events is
preserved if Pa does not exceed the design pressure. In
addition, performance of the containment leakage rate testing
program ensures the validity of the assumptions used in the accident
analyses.
All evaluations and analyses performed to support SG replacement
reflect the proposed values. The results demonstrate that applicable
acceptance criteria (including DNB, RCS pressure and temperature,
LOCA [loss-of-coolant accident] peak clad temperature, containment
pressure and temperature, and dose) continue to be met. Calculations
confirm that the proposed RTS/ESFAS values provide margin to the
safety analysis limits, thereby ensuring that the margin of safety
inherent in the safety analysis limit itself is preserved.
The specific activity limit has no effect on safety limits or
limiting safety system settings. The only impact of the specific
activity limits is on dose consequences for certain design basis
accidents such as SGTR. The proposed change is in the conservative
direction for dose. The SGTR analysis is the most limiting of these
accident dose evaluations. The proposed new analysis demonstrates
that the SGTR consequences remain within allowable SRP guideline
limits, which establish the margin of safety. Since the analysis
results remain below the SRP guidelines, the margin of safety is not
reduced.
The thermal power restrictions imposed by [the] Technical
Specification[s] when there are inoperable main steam line safety
valves [ensure] sufficient relieving capacity during all postulated
transients, thereby maintaining margin of safety for secondary
system pressure.
The proposed in-service inspection program for the RSGs monitors
the integrity of the SG tubing and is consistent with NUREG-0452.
Since the F* repair criteria and sleeving methods specifically
addressed OSG degradation issues, their removal does not involve a
reduction in a margin of safety. Analyses demonstrate that the RSG
tubing retains adequate structural and leakage integrity using the
proposed plugging criteria during normal, transient, and postulated
accident conditions. The RSG tubing design and proposed plugging
criteria are consistent with applicable ASME requirements and do not
allow for operation with indications identified by F* criteria.
The proposed plugging limit maintains the margin of safety by
providing for leakage detection and shutdown in the event of an
unexpected tube leak while minimizing the potential for excessive
leakage or tube burst in the event of [an] MSLB [main steam line
break] or LOCA.
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.

Detroit Edison Company, Docket No. 50-341, Fermi 2, Monroe County,
Michigan

Date of amendment request: September 20, 2000.
Description of amendment request: The proposed amendment would
change Technical Specification (TS) 5.5.7.d to decrease the maximum
allowed pressure drops across control room emergency filtration (CREF)
make-up and recirculation train filters and charcoal adsorbers.
Specifically, the pressure drops would be changed from ``6.0 inches WG
[water gauge]'' to ``3.0 inches WG'' for the CREF makeup train, and
from ``8.0 inches WG'' to ``4.2 inches WG'' for the CREF recirculation
train. Additionally, the words ``(CREF only)'' would be removed to
clarify that standby gas treatment system (SGTS) prefilter is included
in the Ventilation Filter Testing Program (VFTP).
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 changes revise the pressure drop acceptance
criteria of TS Section 5.5.7.d from ``6.0 inches WG'' to ``3.0
inches WG'' for the CREF makeup train, and from ``8.0 inches WG'' to
``4.2 inches WG'' for the CREF recirculation train. The change in
pressure drop reflects the impact of reduced fan speed on system
characteristics. The removal of ``(CREF only)'' is editorial and
clarifies the inclusion of the SGTS prefilters in the VFTP. These
changes assure that the Surveillance procedure appropriately
demonstrate[s] the ability of the CREF trains to perform its
specified function.
No changes in either system design or operating strategies will
be made as a result of these changes. Thus, no opportunity exists to
increase the probability or consequences of a previously analyzed
accident. Therefore, the proposed change does not involve a
significant increase in the probability or consequences of a
previously evaluated accident.
2. The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The proposed change does not involve a change to the plant
operation. As a result, the proposed change does not affect any of
the parameters or conditions that could contribute to the initiation
of any accidents. This change involves the pressure drop across the
filters and adsorbers of the CREF make-up and recirculation trains.
The

[[Page 65341]]

surveillance requirements for performing the actual test have not
changed. The VFTP tests are performed such that the pressure drop
across the combined HEPA [high efficiency particulate adsorber]
filters, the prefilters, and the charcoal adsorbers is less than the
value specified in the acceptance criteria in accordance with
Regulatory Guide 1.52, Revision 2, and ANSI/ASME N510-1980 at the
system flowrate of plus or minus 10 percent. The change involves
restrictive changes in test acceptance criteria and test methodology
and no change in system operation.
No new accident scenarios are created by the lower value of
filter and adsorber pressure drop. No safety-related equipment or
safety functions are altered as a result of this change.
Additionally, the removal of ``(CREF only)'' is editorial and
clarifies the inclusion of the SGTS prefilters in the VFTP.
Therefore, the changes do not create the possibility of a new or
different kind of accident or malfunction from those previously
analyzed.
3. The change does not involve a significant reduction in the
margin of safety.
The proposed change in combination with existing restrictions
within the TS provides assurance that there are no credible
mechanisms to prevent the CCHVAC [control center heating,
ventilation, and air conditioning] system from performing its
specified function. The maximum allowable differential pressure is
more restrictive and corresponds to the reduced fan speed across the
HEPA filters, prefilters, and charcoal adsorbers as a result of this
change. There will be no changes in system operating strategies
because of the inclusion of the make-up moisture separator/prefilter
and test acceptance criteria for the CREF trains. Additionally, the
removal of ``(CREF only)'' is editorial and clarifies the inclusion
of the SGTS prefilters in the VFTP. Therefore, the 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
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Duke Energy Corporation, Docket Nos. 50-369 and 50-370, McGuire Nuclear
Station, Units 1 and 2, Mecklenburg County, North Carolina

Date of amendment request: June 13, 2000.
Description of amendment request: The proposed amendments would
make administrative changes to the McGuire Nuclear Station, Units 1 and
2, Facility Operating Licenses (FOLs). Specifically, they would: (1)
Delete existing License Conditions which have been met by completed
licensee's actions or are imposed by other regulatory requirements, or
(2) make other miscellaneous changes to the McGuire Nuclear Station,
Units 1 and 2, FOLs.
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 the change involve a significant increase in the
probability or consequence of an accident previously evaluated?
No. The proposed amendment to the FOLs are either
administrative, eliminate duplication of other regulatory
requirements or delete License Conditions fully met by Duke Energy
Corporation. No actual plant equipment, operating practices, or
accident analyses are affected by this proposed amendment.
Therefore, the proposed amendment has no impact on the possibility
of any type of accident: new, different, or previously evaluated.
2. Will the change create the possibility of a new or different
kind of accident from any previously evaluated?
No. The proposed amendment to the FOLs [are] either
administrative, eliminate duplication of other regulatory
requirements or delete License Conditions fully met by Duke Energy
Corporation. No actual plant equipment, operating practices, or
accident analyses are affected by this proposed amendment and no
failure modes not bounded by previously evaluated accidents are
created. Therefore, the proposed amendment has no impact on the
possibility of any type of accident: new, different, or previously
evaluated.
3. Will the change involve a significant reduction in a margin
of safety?
No. Margin of safety is associated with confidence in the
ability of the fission product barriers (i.e., fuel and fuel
cladding, reactor coolant system pressure boundary, and containment
structure) to limit the level of radiation dose to the public. The
proposed amendment to the FOLs are either administrative, eliminate
duplication of other regulatory requirements or delete License
Conditions fully met by Duke Energy Corporation. Therefore, no
reduction in any existing margin of safety is involved.

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.

Duke Energy Corporation, Docket Nos. 50-369 and 50-370, McGuire Nuclear
Station, Units 1 and 2, Mecklenburg County, North Carolina

Date of amendment request: August 22, 2000.
Description of amendment request: The proposed amendments would
revise the Technical Specifications and associated Bases to limit the
amount of time a Refueling Water Storage Tank level channel can be in a
trip condition.
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 of consequences of an accident previously evaluated?
No. The proposed change modifies the allowed outage time that a
channel of the Refueling Water Storage Tank (RWST) can be in the
tripped condition from an indefinite period of time to a more
conservative maximum of 48 hours. The Engineered Safety Features
Actuation System (ESFAS) is an accident mitigating system, and not
an accident initiator. Therefore, the proposed change will have no
impact on any accident probabilities. Accident consequences will not
be affected, as no changes are being made to the plant involving a
reduction in reliability or effectiveness of the Emergency Core
Cooling System (ECCS). Consequently, any previous evaluations
associated with accidents will not be affected by this change.
2. Does the change create the possibility of a new or different
kind of accident from any accident previously evaluated?
No. The proposed change does not modify the design or
configuration of the plant. The proposed change provides a more
conservative time limit for a channel to be in the tripped
condition. No physical changes are being made to plant systems,
structures or components nor will the proposed change reduce the
ability of any of the safety related equipment required for accident
mitigation. Consequently, this change does not create the
possibility of a new or different kind of accident from any
previously evaluated.
3. Does this change involve a significant reduction in a margin
of safety?
No. Margin of safety is related to the confidence in the ability
of the fission product barriers to perform their design functions
during and following accident conditions. These barriers include the
fuel cladding, the reactor coolant system, and the containment
system. The proposed change provides a more restrictive time limit
for a channel of the RWST to be in a tripped condition than is
currently allowed by the ITS. The performance of the fission product
barriers will not be degraded by the proposed changes. Consequently,
plant safety analyses will not be affected.

The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three

[[Page 65342]]

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 Generation Company, Docket No. 50-293, Pilgrim Nuclear
Power Station, Plymouth County, Massachusetts

Date of amendment request: September 1, 2000.
Description of amendment request: The proposed amendment would make
a change to Pilgrim Technical Specification Table 4.6-3. The proposed
change substitutes ``21 (approx)'' under the column ``Effective Full
Power Years (EFPY)'' for the current ``18 (approx).'' This proposed
change would defer the second reactor vessel surveillance capsule pull
to allow Pilgrim to pursue participation in the Boiling Water Reactor
Integrated Surveillance Program Plan.
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 standards of 10 CFR 50.92(c). The NRC staff's analysis is
presented below:
The proposed changes do not involve a significant increase in the
probability or consequences of an accident previously evaluated.
Pressure-temperature (P/T) limits (Pilgrim Technical Specifications
Figures 3.6.1, 3.6.2, and 3.6.3) are imposed on the reactor coolant
system to ensure that adequate safety margins against nonductile or
rapidly propagating failure exist during normal operation, anticipated
operational occurrences, and system hydrostatic tests. The P/T limits
are related to the nil-ductility reference temperature, RTndt, as
described in American Society of Mechanical Engineers (ASME) Section
III, Appendix G. Changes in the fracture toughness properties of
reactor pressure vessel (RPV) beltline materials, resulting from the
neutron irradiation and the thermal environment, are monitored by a
surveillance program in compliance with the requirements of 10 CFR Part
50, Appendix H. The effect of neutron fluence on the shift in the nil-
ductility reference temperature of pressure vessel steel is predicted
by methods given in Regulatory Guide (RG) 1.99, Revision 2.
The proposed change is a revision of the second surveillance
capsule withdrawal time, identified in Technical Specification Table
4.6-3, from approximately 18 effective full power years (EFPY) to
approximately 21 EFPY. This change will not affect P/T limits as given
in Pilgrim Technical Specifications Figures 3.6.1, 3.6.2, and 3.6.3.
This change is not related to any accidents previously evaluated. This
change will not affect any plant safety limits or limiting conditions
of operation. The proposed change will not affect reactor pressure
vessel performance because no physical changes are involved and Pilgrim
vessel P/T limits will remain in accordance with RG 1.99, Revision 2
requirements. The proposed change will not cause the reactor pressure
vessel or interfacing systems to be operated outside of their design or
testing limits. Also, the proposed change will not alter any
assumptions previously made in evaluating the radiological consequences
of accidents.
Therefore, the probability or consequences of accidents previously
evaluated will not be increased by the proposed change.
The proposed changes do not create the possibility of a new or
different kind of accident from any accident previously evaluated.
The proposed change revises the second RPV material surveillance
capsule withdrawal time in Pilgrim Technical Specification Table 4.6-3
from approximately 18 EFPY to approximately 21 EFPY. This proposed
change does not involve a modification of the design of plant
structures, systems, or components (SSCs). The proposed change will not
impact the manner in which the plant is operated as plant operating and
testing procedures will not be affected by the change. The proposed
change will not degrade the reliability of SSCs important to safety
because equipment protection features will not be deleted or modified,
equipment redundancy or independence will not be reduced, supporting
system performance will not be downgraded, the frequency of operation
of equipment important to safety will not be increased, and increased
or more severe testing of equipment important to safety will not be
imposed. No new accident types or failure modes will be introduced as a
result of the proposed change. Therefore, the proposed change does not
create the possibility of a new or different kind of accident from that
previously evaluated.
The proposed changes do not involve a significant reduction in a
margin of safety.
Operation in accordance with the existing P-T curves ensures
reactor vessel and cooling system integrity. The capsule pull is a
surveillance technique that provides data for modification of the
curves. The margins will not change without new data from the capsule
pull. The NRC-approved methods used to develop the temperatures
associated with the current curves reside in Pilgrim's TSs and have
been determined to be conservative. The proposed change will not affect
any safety limits, limiting safety system settings, or limiting
conditions of operation. The proposed change does not represent a
change in initial conditions, or in a system response time, or in any
other parameter affecting the course of an accident analysis supporting
the Bases of any Technical Specification. Therefore, the proposed
changes do not involve a significant reduction in any margins of
safety.
Based on the staff's analysis, it appears that the three standards
of 50.92(c) are satisfied. Therefore, the NRC staff proposes to
determine that the amendment request involves no significant hazards
consideration.

FirstEnergy Nuclear Operating Company, Docket No. 50-346, Davis-Besse
Nuclear Power Station, Unit 1, Ottawa County, Ohio

Date of amendment request: August 7, 2000.
Description of amendment request: The proposed changes would revise
Technical Specification (TS) Bases 3/4.3.1 and 3/4.3.2 to clarify the
actions that must be performed when Steam and Feedwater Rupture Control
System (SFRCS) components and SFRCS-actuated components are inoperable.
Specifically, the proposed changes would provide guidance on which TS
actions are applicable for SFRCS-actuated components. Also, the
proposed changes would introduce new TS 3/4.7.1.8 which would provide
appropriate requirements for the Main Feedwater Control Valves and the
Startup Feedwater Control Valves. Additionally, the proposed changes
would introduce new TS 3/4.7.1.9 which would provide requirements for
the Turbine Stop Valves.
Basis for proposed no significant hazards consideration
determination:

[[Page 65343]]

As required by 10 CFR 50.91(a), the licensees have provided their
analysis of the issue of no significant hazards consideration, which is
presented below:

The Davis-Besse Nuclear Power Station (DBNPS) has reviewed the
proposed changes and determined that a significant hazards
consideration does not exist because operation of the Davis-Besse
Nuclear Power Station, Unit No. 1, in accordance with these changes
would:
1a. Not involve a significant increase in the probability of an
accident previously evaluated because no such accidents are affected by
the proposed changes. The amendment application proposes to revise
Technical Specification (TS) Bases 3/4.3.1 and 3/4.3.2, Reactor
Protection System and Safety System Instrumentation, to clarify Steam
and Feedwater Rupture Control System (SFRCS) requirements; to add new
TS 3/4.7.1.8, Main Feedwater Control Valves (MFCVs) and Startup
Feedwater Control Valves (SFCVs); to add new TS 3/4.7.1.9, Turbine Stop
Valves (TSVs); and to make associated changes to the Bases and TS
Index.
The proposed change would provide clear guidance for the actions
required when SFRCS logic and SFRCS-actuated components are inoperable.
The new TSs for MFCVs, SFCVs, and TSVs provide appropriate operational
requirements for these SFRCS-actuated components. The proposed change
will not change any system hardware or testing requirements. Initiating
conditions and assumptions remain as previously analyzed for accidents
in the DBNPS Updated Safety Analysis Report (USAR). The proposed
changes to the TS Bases and Index are consistent with the changes
described above.
The proposed changes are consistent with the intent of NUREG-1430,
``Standard Technical Specifications--Babcock and Wilcox Plants,''
Revision 1, April 1995. The proposed change does not involve a change
to any plant hardware and does not affect the probability of any
equipment malfunction or accident-initiating event.
1b. Not involve a significant increase in the consequences of an
accident previously evaluated because the source term, containment
isolation, or radiological releases are not affected by the proposed
changes. The proposed changes ensure that excessive unavailability of
SFRCS-actuated equipment which is used to mitigate accident
consequences does not occur. The reliability of the plant hardware and
the ability of the SFRCS-actuated equipment to perform its safety
function are not affected. Existing system and component redundancy is
not affected by the proposed changes. The existing system and component
operation is not affected by the proposed changes, and the assumptions
used in evaluating the radiological consequences in the DBNPS USAR are
not invalidated. Therefore, for each postulated accident the
consequences remain bounded by the consequences from the previously
evaluated accidents.
2. Not create the possibility of a new or different kind of
accident from any accident previously evaluated because these proposed
changes do not involve any physical changes to systems or components,
nor do they alter the manner in which the systems or components are
operated.
3. Not involve a significant reduction in a margin of safety
because, for the proposed changes, there are no new or significant
changes to the initial conditions contributing to accident severity or
consequences. Accordingly, there are no significant reductions in a
margin of safety.
On the basis of the above, the DBNPS has determined that the
License Amendment Request does not involve a significant hazards
consideration. As this License Amendment Request concerns a proposed
change to the Technical Specifications that must be reviewed by the
Nuclear Regulatory Commission, this License Amendment Request does not
constitute an unreviewed safety question.

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.

IES Utilities Inc., Docket No. 50-331, Duane Arnold Energy Center, Linn
County, Iowa

Date of amendment request: September 19, 2000.
Description of amendment request: The proposed amendment revises
the Standby Liquid Control (SLC) boron solution requirements in TS
Figure 3.1.7-1 to ensure a minimum boron concentration of 660 parts per
million (ppm) in the reactor.
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 amendment will not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
The current TS SRs ensure acceptable SLC boron solution volume
and concentration values which produce a minimum boron concentration
of 600 ppm in the reactor. This proposed amendment revises the boron
solution requirements to ensure a minimum boron concentration of 660
ppm in the reactor. A minimum boron concentration of 660 ppm in the
reactor is sufficient to initiate and maintain reactor
subcriticality as the nuclear system cools. The DAEC is currently
pursuing the use of GE-14 fuel, power uprate to 1912 MWth and
extended cycle length. Increasing the minimum boron concentration to
660 ppm in the reactor will provide adequate shutdown margin for
these future core designs. A General Electric analysis, using the
approved methods described in Revision 14 of General Electric
Standard Application for Reactor Fuel (GESTAR II), NEDE 24011-P-A,
provides the basis for the increase in minimum boron concentration.
This analysis assumes DAEC operation with an equilibrium core of GE-
14 fuel, operating at 1912 MWth with 24 month cycles and bounds all
planned future core designs.
The concentration requirement of the SLC boron solution will
continue to comply with the requirements of 10 CFR 50.62(c)(4).
The proposed editorial change to the title of TS Figure 3.1.7-1
provides clarity only and does not alter performance of TS SR
3.1.7.1 and SR 3.1.7.5.
Therefore, this proposed amendment will not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. The proposed amendment will not create the possibility of a
new or different kind of accident from any accident previously
evaluated.
Ensuring a minimum boron concentration of 660 ppm in the reactor
will result in an increase in the acceptable minimum volume of boron
solution in the SLC tank. The tank can accept the increased volume
of boron solution. The tank low and high level alarms will be
altered; these alarms alert the operator to take action in the event
boron solution volume is decreasing or increasing, respectively.
Increasing the volume in the SLC tank and increases to the low and
high level alarm setpoints will have no effect on operator actions
to maintain system operability. Revising the SLC boron solution
requirements to ensure a minimum boron concentration of 660 ppm in
the reactor cannot create a new or different kind of accident.
The proposed editorial change to the title of TS Figure 3.1.7-1
provides consistent wording between the Figure, TS SR 3.1.7.1 and
the TS BASES to avoid potential inconsistencies when determining the
tank volume acceptability.
Therefore this proposed amendment will not create the
possibility of a new or different

[[Page 65344]]

kind of accident from any accident previously evaluated.
3. The proposed amendment will not involve a significant
reduction in a margin of safety.
DAEC TS SRs ensure SLC boron solution volume and concentration
values which produce a minimum boron concentration of 600 ppm in the
reactor. This proposed amendment revises SLC boron solution
requirements to ensure a minimum boron concentration of 660 ppm in
the reactor. A boron concentration of 660 ppm in the reactor is
sufficient to initiate and maintain reactor subcriticality as the
nuclear system cools. The DAEC is currently pursuing the use of GE-
14 fuel, power uprate to 1912 MWth and extended cycle length. A
General Electric (GE) analysis, using the approved methods described
in Revision 14 of General Electric Standard Application for Reactor
Fuel (GESTAR II), NEDE 24011-P-A, provides the basis for the
increase in minimum boron concentration. GE's analysis demonstrated
that at a minimum boron concentration of 600 ppm in the reactor, the
SLC shutdown margin was marginal with respect to the TS requirement
for shutdown margin. At a minimum boron concentration of 660 ppm in
the reactor, sufficient margin is maintained such that TS Section
3.1.1 will be met under all anticipated conditions. The GE analysis
assumes DAEC operation with an equilibrium core of GE-14 fuel,
operating at 1912 MWth with 24 month cycles and bounds all planned
future core designs.
The concentration requirement of the SLC boron solution will
continue to comply with the requirements of 10 CFR 50.62(c)(4).
The SLC system is designed to inject a quantity of boron that
produces a minimum boron concentration of 600 ppm in the reactor. An
additional 25% of that quantity of boron is also injected to
compensate for imperfect mixing, leakage and volume in other small
piping connected to the reactor. This margin will be maintained such
that an additional 25% of the quantity of boron required to achieve
a minimum boron concentration of 660 ppm in the reactor will also be
injected. Therefore, this proposed amendment will not involve a
significant reduction in a margin of safety.
The proposed editorial change to the title of TS Figure 3.1.7-1
provides consistent wording between the Figure, TS SR 3.1.7.1 and
the TS BASES to avoid potential inconsistencies when determining
tank volume acceptability.

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. 50-220, Nine Mile Point
Nuclear Station Unit No. 1, Oswego County, New York

Date of amendment request: September 26, 2000.
Description of amendment request: The licensee proposed to amend
the unit's Technical Specifications (TSs), Sections 3.3.0, 3.3.2 thru
3.3.5 and 3.3.7 to allow performance of reactor vessel hydrostatic or
leakage tests, and scram time and excess flow check valve tests, when
the reactor system temperature is above 215 degrees Fahrenheit and the
reactor is not critical, without having to maintain primary containment
integrity. These proposed changes are consistent with the guidelines of
NUREG-1433, Revision 1, ``Standard Technical Specifications, General
Electric Plants, BWR/4.'' Concurrently, the licensee proposed to amend
TS Sections 3.4.0 thru 3.4.5 to require reactor building (secondary
containment) integrity when the reactor system temperature is above 215
degrees Fahrenheit. This will ensure that, should accidents occur
during the above tests, the reactor building will perform its function
to contain radiological releases. The licensee also proposed to impose
a dose-equivalent iodine level of 1.5 microcuries per gram (as opposed
to 9.47 microcuries per gram allowed during plant operation) during the
above conditions to limit radiological consequences of possible
accidents to limits bound by the previously analyzed main steam line
break accident.
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 standards of 10 CFR 50.92(c). The NRC staff's review is
presented below:
The operation of the unit in accordance with the proposed amendment
will not involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed TS changes will result in not requiring containment
integrity, but requiring reactor building integrity (secondary
containment) during performance of the specified tests. These are
changes in configuration (no hardware design change is involved) to
permit testing of various systems or components under different
conditions. The changed conditions are not considered precursor of
accidents. Accordingly, the probability of an accident previously
evaluated is not increased.
Accidents could occur during a test. As part of the proposed TS
change, the licensee proposed to limit the dose-equivalent iodine level
to ensure that the consequences of possible accidents will continue to
be bounded by a previously analyzed accident, the main steam line break
accident. Thus, there will not be any increase in the consequences of
an accident previously evaluated.
The operation of the unit in accordance with the proposed amendment
will not create the possibility of a new or different kind of accident
from any accident previously evaluated. No hardware design change is
involved with the proposed TS changes. Other than the changes in the
configuration of the containment, the reactor building, and the
permissible dose-equivalent iodine level, there are no other procedural
changes. Therefore, the proposed amendment will not create the
possibility of a new or different kind of accident from any previously
evaluated.
The operation of the unit in accordance with the proposed amendment
will not involve a significant reduction in a margin of safety.
The proposed TS changes will not adversely affect the performance
characteristics and intended functions of systems and components
covered by the above-listed TS sections. The tests, not affected by the
proposed amendment, will ensure the ability of the subject systems and
components to perform their intended function. Therefore, the proposed
changes do 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 amendment request involves no significant hazards
consideration.

Northeast Nuclear Energy Company, et al., Docket No. 50-336, Millstone
Nuclear Power Station, Unit No. 2, New London County, Connecticut

Date of amendment request: August 25, 2000.
Description of amendment request: Millstone Unit No. 1 (MP1) is
being decommissioned. To support this activity, several modifications
are

[[Page 65345]]

required to modify/eliminate MP1 systems that support the operation of
structures, systems, and components that are shared or common to
Millstone Unit No. 2 (MP2) and Millstone Unit No. 3 (MP3). One of the
separation projects entails the replacement of the existing MP1 to MP2
4160-volt cross-tie with a new MP3 to MP2 4160-volt cross-tie.
Northeast Nuclear Energy Company (NNECO) has proposed a one time
extension to the allowed outage time (AOT) for Action a.2 of Technical
Specification (TS) 3.8.1.1, ``Electrical Power Systems--A. C. Sources--
Operating'' in order to complete this modification. The proposed change
would extend the AOT from 72 hours to 14 days, provided the MP3 station
blackout (SBO) diesel generator (DG) is available to supply MP2;
otherwise the AOT would only be extended to 7 days.
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 offsite circuits supply power to equipment required to
support the safe shutdown and post-accident operations of MP2. The
preferred off-site power supply is from the 345 kV [kilovolt]
switchyard, through the reserve station service transformer (RSST).
The alternate (delayed) source of offsite power is the 4.16 kV
cross-tie from MP1 via bus 14H.
To ensure that the probability of a complete loss of offsite
power is not significantly increased, the MP1 4.16 kV cross-tie will
only be removed from service when the weather conditions and
forecast are favorable. Additionally, during the time that the
alternate offsite source is inoperable, actions will be taken to
protect the operable offsite circuit (i.e., no work will be
conducted that could challenge the operability of the offsite
circuit).
Although the offsite circuits provide power to components that
help mitigate the consequences of accidents previously evaluated,
the extension in the AOT does not affect any of the assumptions used
in the deterministic evaluations of these accidents. Thus, this
change will not increase the consequences of any accident previously
analyzed.
Based on the above, the proposed change does not involve a
significant increase in the probability or consequences of an
accident previously analyzed.
2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
The proposed change is an extension to a TS AOT. It does not
alter the physical design, configuration, or method of operation of
the plant. Therefore, the proposed change will not create the
possibility of a new or different kind of accident from any
previously analyzed.
3. Involve a significant reduction in a margin of safety.
During the implementation of the modification to provide MP2
with a 4.16 kV cross-tie with MP3, NNECO will:
a. Appropriately consider the 7 day and 14 day weather forecasts
prior to removing the MP2 4.16 kV cross-tie with MP1 from service to
minimize the potential for loss of offsite power due to severe
weather or salt spray.
b. Protect the equipment redundant to the systems removed from
service or whose power supply is affected by the modification. This
includes limiting work on the 345 kV lines, the switchyard, the
RSST, the diesel generators, the service water system, the high
pressure safety injection system, and the reactor building closed
cooling water system. This restriction will ensure that MP2 will
remain capable of mitigating any potential design basis accident
during the implementation of the modification.
c. Within 7 days of entering Action a. of TS 3.8.1.1, establish
the capability to supply MP2 with power from the MP3 SBO DG via
operator actions within one hour of an event resulting in a loss of
the remaining offsite source of power. The capability to utilize the
MP3 SBO DG is a contingency measure (i.e., will be able to serve as
a temporary diesel).
Additionally, NNECO has evaluated the dominant sequences
affecting plant risk using probabilistic safety analysis techniques.
The analysis determined that the Delta Core Damage Probability
associated with the extended allowed outage time was small.
There will be no significant reduction in a margin of safety
because the increased risk is acceptable, focus on maintaining the
operability of the redundant equipment and systems will be
increased, the probable weather conditions will be appropriately
considered, and the capability to supply MP2 with power from the MP3
SBO DG via operator action will be established within 7 days of
entering Action a. of TS 3.8.1.1. The capability to utilize the MP3
SBO DG is a contingency measure (i.e., will be able to serve as a
temporary diesel).

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.

Northeast Nuclear Energy Company, et al., Docket Nos. 50-336 and 50-
423, Millstone Nuclear Power Station, Unit Nos. 2 and 3, New London

Date of amendment request: August 25, 2000.
Description of amendment request: Millstone Unit No. 1 (MP1) is
being decommissioned. To support this activity, several modifications
are required to modify/eliminate MP1 systems that support the operation
of structures, systems, and components that are shared or common to
Millstone Unit No. 2 (MP2) and Millstone Unit No. 3 (MP3). One of the
separation projects entails the replacement of the existing MP1 to MP2
4160-volt cross-tie with a new MP3 to MP2 4160-volt cross-tie.
Northeast Nuclear Energy Company (licensee) has evaluated this proposed
new cross-tie utilizing the criteria of 10 CFR 50.59. The modification
involves four unreviewed safety questions (USQs). One USQ pertains to
MP2 and three USQs pertain to MP3. The licensee is requesting approval
of the USQs.
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:

Basis for No Significant Hazards Consideration--Millstone Unit No.
2 Unreviewed Safety Question

1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The test that will be performed to verify the ability of the
cross-tie to supply approximately 3 MVA of power from MP3 to MP2
will require parallel operation of the MP3 SBO [station blackout] DG
[diesel generator] with the MP2 4160 Volt system. To ensure that the
MP3 SBO DG and associated connection will be isolated immediately
should any abnormal event or failure occur at MP2, a special Class
1E instantaneous overcurrent relaying scheme will be used. This will
provide additional assurance that if a fault occurs in the MP3 SBO
DG or the associated cross-tie cabling, it will be isolated
immediately and should not affect operability of the MP2 safety
related 4160 Volt system. In addition, if a

[[Page 65346]]

loss of normal power occurs at MP2 during the test, the undervoltage
condition will be detected by the credited undervoltage scheme, and
MP2 will respond as designed to the loss of power.
The performance of this test does not significantly alter the
manner in which the plant is operated. There will be no adverse
effect on plant operation or accident mitigation equipment. The
response of the plant and the operators following a design basis
event will not be significantly different. Therefore, the proposed
activity does not involve a significant increase in 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 installation of the Class 1E instantaneous overcurrent relay
scheme to be used during performance of this test will provide
additional assurance that the MP2 safety related/busses will remain
operable during the test to parallel the MP3 SBO DG to the MP2 4160
Volt system. The failure of the temporary overcurrent protection
scheme would have the same effect as failure of the existing
overcurrent protection scheme. Therefore, the proposed activity does
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.
The installation of the Class 1E instantaneous overcurrent relay
scheme to be used during performance of this test will provide
additional assurance that the MP2 safety related busses will remain
operable during the test to parallel the MP3 SBO DG to the MP2 4160
Volt system. This will provide additional assurance that if a fault
occurs in the MP3 SBO DG or the associated cross-tie cabling, it
will be isolated immediately and should not affect operability of
the MP2 safety related 4160 Volt system. In addition, if a loss of
normal power occurs at MP2 during the test, the undervoltage
condition will be detected by the credited undervoltage scheme, and
MP2 will respond as designed to the loss of power.
The proposed activity will have no adverse effect on plant
operation or equipment important to safety. The plant response to
the design basis accidents will not change and the accident
mitigation equipment will continue to function as assumed in the
design basis accident analysis. Therefore, the proposed activity
does not involve a significant reduction in a margin of safety.

Basis for No Significant Hazards Consideration--Millstone Unit No.
3 Unreviewed Safety Questions

1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.

MP3 USQ 1

The MP3 to MP2 4160 Volt cross-tie will impose up to an
additional 3 MVA load on MP3. As a result, the minimum acceptable
switchyard voltage for MP3 will increase from 334 kV to 337 kV. The
analysis performed to support the new design shows that, with a
minimum voltage of 337 kV in the switchyard, MP3 will remain
connected to offsite power. The minimum voltage protection assures
that acceptable starting and running voltages are present for the
safety systems that may be required to operate should a loss of
coolant accident (limiting design basis event) occur at MP3 while
MP2 is being supplied with the safe shutdown load of 3 MVA from
either the MP3 RSST [reserve station service transformer] or the MP3
NSST [normal station service transformer]. Thus, the MP3 offsite
connection will not be tripped when offsite power is available.
The extra loading imposed by the MP2 safe shutdown loads on the
MP3 power supplies is within the MP3 capability to simultaneously
supply the worst case MP3 normal and accident loads. The ability of
MP3 to mitigate design basis accidents and events is not adversely
affected by the new design.
This activity does not significantly alter the manner in which
the plant is operated. There will be no adverse effect on plant
operation or accident mitigation equipment. Also, the response of
the plant and the operators following a design basis event will not
be significantly different. Therefore, this activity does not
involve a significant increase in the probability or consequences of
an accident previously evaluated.

MP3 USQ2

The proposed design change will allow the MP3 RSST (or the MP3
NSST, if the MP3 RSST is unavailable) to provide the alternate
offsite source for MP2 to meet GDC [General Gesign Criterion] 17
requirements. If the MP3 RSST is not available, MP2 will need to
credit the MP3 NSST as the alternate offsite power supply for GDC 17
compliance. The connection for the MP3 NSST is between breakers 13T
and 14T. This connection point only provides 1 breaker separation
(13T) between the MP2 RSST and the MP3 NSST. If breaker 13T is
closed, this arrangement does not provide adequate separation
between the two offsite sources as required by GDC 17. Opening
breaker 13T when MP3 is shutdown will provide the required
separation for MP2, but it will reduce the reliability of the
offsite supply for MP3. Therefore, opening the 13T breaker to allow
MP2 to meet GDC 17 requirements increases the probability of a loss
of offsite power at MP3 when shutdown.
A loss of offsite power at MP3 due to a fault in the offsite
distribution network is a low probability event. When combined with
the expected frequency of removing the MP3 RSST from service of once
per MP3 refueling outage, the probability of a loss of offsite power
at MP3 when shutdown as a result of breaker 13T being open is low.
In addition, the MP3 shutdown risk program will evaluate the impact
of removing the MP3 RSST from service, and plan accordingly. This
will ensure the MP3 RSST will be removed from service when the
shutdown risk is determined to be acceptably low. Also, at least one
MP3 EDG will be available, as required by Technical Specifications,
to supply power to necessary loads if offsite power is lost.
This activity does not significantly alter the manner in which
the plant is operated. There will be no adverse effect on accident
mitigation equipment.
Also, the response of the plant and the operators following a
design basis event will not be significantly different. Therefore,
this activity does not involve a significant increase in the
probability or consequences of an accident previously evaluated.

MP3 USQ 3

The connection of an additional 3 MVA load for MP2 onto the MP3
electrical distribution system will increase the short circuit fault
levels on the MP3 electrical distribution system. If worst case
conditions are established, the additional contribution from the MP2
loads would increase the fault level to above the switchgear
ratings. The worst case short circuit conditions occur with MP3 at
full power, the switchyard at its maximum voltage, an MP3 EDG
paralleled to the bus for surveillance testing, and the MP3 to MP2
cross-tie supplying 3 MVA of power to MP2.
Although the fault levels could exceed the MP3 switchgear and
circuit breaker ratings, it is not expected that the worst case
conditions will be frequently established. For the majority of
scenarios, this situation can be avoided because the new design
allows the 3 MVA of power for MP2 to be supplied by either MP3 bus
34A or 34B. Procedural guidance will be provided to select the MP3
bus (34A or 34B) to supply power to MP2 that powers the opposite
train from the train associated with the MP3 EDG to be tested. Even
if the worst case plant configuration cannot be avoided, there is a
low probability of event occurrence given the low probability of a
bus fault coincident with the short time that the MP3 EDG would be
paralleled to the system. In addition, the event would only affect
one MP3 train of safety related equipment. The other train will be
available to function as assumed to mitigate any accidents that may
occur.
The use of the MP3 to MP2 cross-tie does not significantly alter
the manner in which the plant is operated. Considering the low
likelihood of a fault occurring concurrently with worst case
conditions, and that only one MP3 train of safety related equipment
should be affected, sufficient accident mitigation equipment will be
available to mitigate a design basis accident. In addition, the
response of the plant and the operators following a design basis
event will not be significantly different. Therefore, this activity
does not involve a significant increase in 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.

MP3 USQ 1

The ability to supply 3 MVA of power from MP3 to MP2 will reduce
the margin between the minimum switchyard voltage and the minimum
acceptable switchyard voltage. However, the extra loading imposed by
the MP2 safe shutdown loads on the MP3 power supplies is within the
MP3 capability to simultaneously supply the worst case MP3 normal
and accident loads. As a result, the response of the plant and the
operators following an accident will not be

[[Page 65347]]

significantly different. There will be no adverse effect on accident
mitigation equipment and no new failure modes will be introduced.
Therefore, the activity will not create the possibility of a new or
different kind of accident from any previously evaluated.

MP3 USQ 2

Maintaining breaker 13T and its associated disconnect switches
open to ensure separation and independence of the two MP2 offsite
sources is a change to the normal configuration of MP3. The new
configuration involves the opening of a breaker. It does not involve
any other physical changes to the plant or the operating
methodology. This activity does reduce the diversity of offsite
power supplies for the MP3 NSST, which increases the potential for a
loss of offsite power at MP3. However, the plant response to a loss
of offsite power because breaker 13T is open will not be
significantly different from any previously analyzed loss of offsite
power. Therefore, opening breaker 13T and its associated disconnect
switches will not create the possibility of a new or different kind
of accident from any previously evaluated.

MP3 USQ 3

The connection of an additional 3 MVA load for MP2 onto the MP3
electrical distribution system will increase the short circuit fault
levels on the MP3 electrical distribution system. In the worst case,
the short circuit fault could lead to a loss of one MP3 train of
safety related equipment. However, the safety related equipment in
the other train would remain capable of mitigating the event. The
loss of a train of safety-related equipment is an analyzed event.
Therefore, this activity will not introduce the possibility of a new
or different kind of accident than any previously evaluated.
3. Involve a significant reduction in a margin of safety.

MP3 USQ 1

The MP3 to MP2 4160 Volt cross-tie will impose up to an
additional 3 MVA load on MP3. As a result, the minimum acceptable
switchyard voltage for MP3 will increase from 334 kV to 337 kV. The
margin between the minimum switchyard voltage (345 kV) and the
minimum acceptable switchyard voltage will decrease from 11 kV to 8
kV. This is an improvement for MP2. However, it is a reduction in
the operating margin for MP3.
The analysis performed to support the new design shows that,
with a minimum voltage of 337 kV in the switchyard, MP3 will remain
connected to offsite power. The minimum voltage protection assures
that acceptable starting and running voltages are present for the
safety systems that may be required to operate should a loss of
coolant accident (limiting design basis event) occur at MP3 while
MP2 is being supplied with the safe shutdown load of 3 MVA from
either the MP3 RSST or the MP3 NSST. Thus, the MP3 offsite
connection will not be tripped when offsite power is available.
The extra loading imposed by the MP2 safe shutdown loads on the
MP3 power supplies is within the MP3 capability to simultaneously
supply the worst case MP3 normal and accident loads. As a result,
the response of the plant and the operators following an accident
will not be significantly different. There will be no adverse effect
on plant operation or equipment important to safety. The plant
response to the design basis accidents will not change and the
accident mitigation equipment will continue to function as assumed
in the design basis accident analysis. Therefore, this activity does
not involve a significant reduction in a margin of safety.

MP3 USQ 2

The proposed design change will allow the MP3 RSST (or the MP3
NSST, if the MP3 RSST is unavailable) to provide the alternate
offsite source for MP2 to meet GDC 17 requirements. If the MP3 RSST
is not available, MP2 will need to credit the MP3 NSST as the
alternate offsite power supply for GDC 17 compliance. This will
require the 13T breaker to be open to meet GDC 17 requirements. As a
result, the probability of a loss of offsite power at MP3 will
increase.
A loss of offsite power at MP3 due to a fault in the offsite
distribution network is a low probability event. When combined with
the expected frequency of removing the MP3 RSST from service of once
per MP3 refueling outage, the probability of a loss of offsite power
at MP3 when shut down as a result of breaker 13T being open is low.
In addition, the MP3 shutdown risk program will evaluate the impact
of removing the MP3 RSST from service, and plan accordingly. This
will ensure the MP3 RSST will be removed from service when the
shutdown risk is determined to be acceptably low. Also, at least one
MP3 EDG will be available, as required by Technical Specifications,
to supply power to necessary loads if offsite power is lost.
The plant response to the design basis accidents will not change
with breaker 13T open, and the accident mitigation equipment will
continue to function as assumed in the design basis accident
analysis. Therefore, this activity does not involve a significant
reduction in a margin of safety.

MP3 USQ 3

The connection of an additional 3 MVA load for MP2 onto the MP3
electrical distribution system will increase the short circuit fault
levels on the MP3 electrical distribution system. If worst case
conditions are established, the additional contribution from the MP2
loads would increase the fault level to above the switchgear
ratings. The worst case short circuit conditions occur with MP3 at
full power, the switchyard at its maximum voltage, an MP3 EDG
paralleled to the bus for surveillance testing, and the MP3 to MP2
cross-tie supplying 3 MVA of power to MP2.
Although the fault levels could exceed the MP3 switchgear and
circuit breaker ratings, it is not expected that the worst case
conditions will be frequently established. For the majority of
scenarios, this situation can be avoided because the new design
allows the 3 MVA of power for MP2 to be supplied by either MP3 bus
34A or 34B. Procedural guidance will be provided to select the MP3
bus (34A or 34B) to supply power to MP2 that powers the opposite
train from the train associated with the MP3 EDG to be tested. Even
if the worst case plant configuration cannot be avoided, there is a
low probability of event occurrence given the low probability of a
bus fault coincident with the short time that the MP3 EDG would be
paralleled to the system. In addition, the event would only affect
one MP3 train of safety related equipment. The other train will be
available to function as assumed to mitigate any accidents that may
occur.
The response of the plant and the operators following a design
basis event will not be significantly different when using the MP3
to MP2 4160 Volt cross-tie. The accident mitigation equipment will
continue to function as assumed in the design basis accident
analysis. Therefore, this activity 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.

Nuclear Management Company, LLC, Docket No. 50-305, Kewaunee Nuclear
Power Plant, Kewaunee County, Wisconsin

Date of amendment request: November 18, 1999, as supplemented
August 7, 2000.
Description of amendment request: The proposed amendment to the
Kewaunee Nuclear Power Plant Technical Specifications requests approval
to increase the allowable number of spent fuel assemblies stored in the
spent fuel pools.
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. In the analysis of
the safety issues concerning the expanded pool canal storage
capacity, the following previously postulated accident scenarios
have been considered:

a. A spent fuel assembly drop in the Spent Fuel Pool
b. Loss of Spent Fuel Pool cooling flow
c. A seismic event

The probability that any of the accidents in the above list can
occur is not significantly

[[Page 65348]]

increased by the modification. The probabilities of a seismic event
or loss of SFP cooling flow are not influenced by the proposed
changes. The probability of an accidental fuel assembly drop is
primarily influenced by the methods used to lift and move the fuel.
The method of handling fuel during the loading of the canal racks
will be the same as current fuel handling methods, since the same
equipment (i.e., Spent Fuel Handling Crane) and the same procedural
guidance will be used. Since the methods used to move fuel during
normal operations remain nearly the same as those used previously,
there is no significant increase in the probability of an accident.
Accordingly, the proposed modification does not involve a
significant increase in the probability of an accident previously
evaluated.
The consequences of the previously postulated scenarios for an
accidental drop of a fuel assembly in the SFP have been re-evaluated
for the proposed change and were determined to be bounded by the
existing analysis. The results show that the postulated accident of
a fuel assembly striking the top of the storage racks will not
distort the racks sufficiently to impair their functionality. The
resulting structural damage to a falling assembly and/or a stored
assembly has been determined to remain unchanged. The minimum
subcriticality margin, Keff less than or equal to 0.95,
will be maintained. The structural damage to the SFP structure, pool
liner, and fuel assembly resulting from a fuel assembly drop
striking the pool floor or another assembly located within the racks
remains unchanged. The resulting structural damage to these items
subsequent to this event is not influenced by the proposed changes.
The consequences of a loss of SFP cooling have been evaluated
and found to have no increase. The concern with this accident is a
reduction of SFP water inventory from bulk pool boiling resulting in
uncovering fuel assemblies. This situation would lead to fuel
failure and subsequent significant increase in offsite dose. Loss of
SFP cooling at Kewaunee is mitigated by ensuring that a sufficient
time period exists between the loss of forced cooling and uncovering
fuel. This period of time is compared against a reasonable period to
re-establish cooling or supply an alternative water source (such as
service water, makeup water, or fire protection system water). This
evaluation included the determination of the time to boil. The time
to boil represents the onset of loss of pool water inventory and is
commonly used as a gage for establishing the comparison of
consequences before and after a refueling project. The heat up rate
in the SFP is a nearly linear function of the fuel decay heat load.
The fuel decay heat load will increase subsequent to the proposed
changes because of the increase in the number of stored assemblies.
The heat up rate established for the limiting heat load conditions
prior to the addition of canal racking was 10.8 deg.F per hour. This
would result in the pool temperature increasing from the maximum
design temperature of 150 deg.F to boiling in a period of 5.7 hours.
The heat up rate established for the limiting heat load conditions
subsequent to the proposed changes has been determined as 7.5 deg.F
per hour. This would result in the pool temperature increasing from
the maximum design temperature of 150 deg.F to boiling in a period
of 8.4 hours.
This time to boil comparison was made for limiting heat load
conditions. However, the end of this period of time does not
represent the onset of any significant increase in offsite doses. As
stated above, this consequence would result after fuel is uncovered
through unchecked boiling and the resulting water level drop of
approximately 25 feet to the top of the fuel storage racks. This
depth is conservative, since the top of active fuel is below this
level. Subsequent to the proposed changes under limiting heat loads
the maximum boil-off rate will decrease to 40.9 gpm. This will
result in the time lapse between loss of SFP cooling and the
uncovering of the racks to increase to 48.5 hours.
As stated above, subsequent to racking the canal, the time to
boil after loss of forced cooling in the most severe scenario was
8.4 hours. The ensuing rate of evaporative loss would not result in
the fuel being uncovered until after an additional 40.1 hours. The
margin concerning time to boil will increase due to the proposed
modification. This increased margin is due to the conservatism of
the assumptions previously used to determine the heat load for this
condition (i.e. the assumption that all fuel assemblies in the core
were transferred to the pool instantaneously). Also, another factor
is that the required incore hold time prior to fuel movement will
increase from 100 hours to 148 hours. Therefore, the calculated time
to boil in this most severe scenario will increase subsequent to the
proposed modification. In the unlikely event that all pool cooling
is lost, sufficient time will continue to be available subsequent to
the proposed changes for the operators to provide alternate means of
cooling (i.e., service water, makeup water, or fire protection
system water) before fuel is uncovered. Therefore, the proposed
changes represent no increase in the consequences of a loss of pool
cooling.
The consequences of a design basis seismic event are not
increased. The consequences of this accident are evaluated on the
basis of subsequent fuel damage or compromise of the fuel storage or
building configurations leading to radiological or criticality
concerns. The canal racks have been analyzed and found to properly
function during seismic motion. The stored fuel has been determined
to remain intact and the storage racks maintain the fuel and fixed
poison configurations subsequent to a seismic event. The structural
capability of the pool and liner will not be exceeded under the
appropriate combinations of dead weight, thermal, and seismic loads.
The SFP structure will remain intact during a seismic event and will
continue to adequately support and protect the fuel racks, stored
fuel, and pool coolant. Thus, the consequences of a seismic event
are not increased.
Therefore, it is concluded that the proposed changes do not
significantly increase the probability or consequences of any
accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any previously analyzed.
During and following project implementation, the spent fuel must
be safely stored, meeting the requirements 10 CFR 20 and 10 CFR 100.
The installation activities as well as the use of the canal racks
must be evaluated for the possibility of creating a new or different
kind of accident from any previously analyzed.
This evaluation was done by reviewing the differences between
the analyses and assumptions associated with the proposed storage
configuration (existing racks plus canal racks) with those of the
existing storage configuration. The accident scenarios associated
with the existing racks were then reviewed to determine if the
possibility of a new type of accident would be introduced by the
implementation of the proposed modification. Also, the installation
activities were evaluated.
Due to the proposed changes, the following events were
considered as the only events which might represent a new or
different kind of accident:
a. An accidental drop of a rack module into the pool during
construction activity.
b. Fuel assembly mispositioning accident in the canal.
A construction accident resulting in a rack drop is an unlikely
event. A rack-lifting rig will be used to lift and suspend the racks
using the existing Fuel Handling Building crane. The crane, hoists
and lifting rig have been or will be designed, tested and inspected
to ensure that they will properly lift and transport the new racks.
The postulated rack drop event is commonly referred to as a ``heavy
load drop'' over the pools. Heavy loads will not be allowed to
travel over any racks containing fuel assemblies. The area of
concern represented by this event is that the pool structure will be
compromised leading to loss of moderator/coolant. The question of a
new or different type of event is answered by determining whether
heavy load drops of this type have been considered previously. The
last phase of the re-racking of the SFPs at KNP was completed in
1987. The rack modules transported during installation of the pool
re-racking project were significantly larger than those associated
with the proposed canal rack project. Also, the KNP Technical
Specifications state that ``Placement of additional fuel storage
racks is permitted, however, these racks must not traverse directly
above spent fuel stored in the pools''. All movements of heavy loads
will be strictly controlled by procedure, will follow approved safe
load paths, and will be performed by qualified personnel. Therefore,
the rack drop does not represent a new or different kind of
accident.
Fuel assembly mispositioning in the canal is an unlikely event
since assembly placement will be administratively controlled. The
administrative controls will include positive, visual identification
of each fuel assembly to be stored in the canal racks. The
mispositioning event for the canal racks represents a change from
the previously analyzed condition, since Kewaunee currently has no
restriction on fuel storage.

[[Page 65349]]

However, the mispositioning event in the canal does not represent a
new or different kind of accident. A fuel assembly mispositioning
event has been previously analyzed for the existing racks and was
found to be acceptable. The new mispositioning event for the canal
racks was evaluated using similar techniques with similar acceptance
criteria and was also shown to be acceptable. Therefore, since both
events represent the mispositioning of a fuel assembly, the
mispositioning of an assembly in the canal racks is not considered
to represent a new or different kind of accident.
Under the extremely unlikely conditions of a mispositioning
event involving the placement of a fresh (un-burned) fuel assembly
in the canal racks, the boron in the pool water will maintain the
required subcriticality margin. Only a small fraction of the minimum
pool boron concentration required by the KNPP Technical
Specifications would be required for this condition. Under the
postulated accident condition of a total loss of boron from the pool
water, proper subcriticality margin would exist. The multiple
accident scenario of the extremely unlikely mispositioning event
combined with a postulated total loss of pool boron is a non-
credible condition. Therefore, although credit is taken for a small
amount of boron in the pool water for one accident condition, a
decrease of pool boron concentration is not a new or different kind
of accident from any previously analyzed.
The proposed change does not involve the modification of any
equipment credited in the mitigation of the design basis accidents.
The proposed change meets all applicable requirements for the safe
storage of spent fuel at KNP. Therefore, the potential for a new or
previously unanalyzed accident is not created by the implementation
of this modification.
The refueling canal does not have floor drains. Therefore,
draining the refueling canal through a floor drain is not a
postulated event.
3. Involve a significant reduction in the margin of safety.
The function of the SFP is to store the fuel assemblies in a
subcritical and coolable configuration through all environmental and
abnormal loadings, such as an earthquake or fuel assembly drop. The
new rack design must meet all applicable requirements for safe
storage and be functionally compatible with the SFP.
WPSC has addressed the safety issues related to the expanded
pool storage capacity in the following areas:

a. Material, mechanical and structural considerations
b. Nuclear criticality
c. Thermal-hydraulic and pool cooling

The mechanical, material, and structural designs of the new
racks have been reviewed in accordance with the applicable
provisions of the NRC Guidance entitled, ``Review and Acceptance of
Spent Fuel Storage and Handling Applications''. The rack materials
used are compatible with the spent fuel assemblies and the SFP
environment. The design of the new racks preserves the proper margin
of safety during abnormal loads such as a dropped assembly and
tensile loads from a stuck assembly. It has been shown that such
loads will not invalidate the mechanical design and material
selection to safely store fuel in a coolable and subcritical
configuration.
The methodology used in the criticality analysis of the expanded
SFP meets the appropriate NRC guidelines and ANSI standards. The
margin of safety for subcriticality is maintained by having the
neutron multiplication factor equal to, or less than, 0.95 under all
accident conditions, including uncertainties. This criterion is the
same as that used previously to establish criticality safety
evaluation acceptance and remains satisfied for all analyzed
accidents. Therefore, the accepted margin of safety remains the
same.
The thermal-hydraulic and cooling evaluation of the pool
demonstrated that the pool can be maintained below the specified
thermal limits under all required design conditions. The pool
temperature will not exceed 140 deg.F during the failure of a
cooling pump under normal offload conditions. The pool temperature
will remain below the maximum design temperature of 150 deg.F under
maximum heat load conditions. The maximum local water temperature in
the hot channel will remain below the boiling point. The fuel will
not undergo any significant heat up after an accidental drop of a
fuel assembly on top of the rack blocking the flow path. Following a
loss of cooling to the pool sufficient time exists (48.5 hours for
the limiting heat load) for the operators to intervene and line up
alternate cooling paths and the means of inventory makeup before the
onset of pool boiling. The thermal limit specified for the
evaluations performed to support the proposed change is the same as
was used in the previous evaluation. Therefore, the accepted margin
of safety remains the same.
Thus, it is concluded that the 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.

South Carolina Electric & Gas Company (SCE&G), South Carolina Public
Service Authority, Docket No. 50-395, Virgil C. Summer Nuclear Station
(VCSNS), Unit No. 1., Fairfield County, South Carolina

Date of amendment request: September 14, 2000.
Description of amendment request: The proposed changes will delete
Technical Specification (TS) Section 6.2.3 and revise TS Sections 6.3.1
and 6.5.2.8 to remove the references to the Independent Safety
Engineering Group (ISEG).
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:

South Carolina Electric & Gas Company (SCE&G) has evaluated the
proposed changes to the VCSNS TS described above against the
significant Hazards Criteria of 10 CFR 50.92 and has determined that
the changes do not involve any significant hazard. The following is
provided in support of this conclusion.
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
The proposed amendment is a programmatic and administrative
change to delete the ISEG. The requirement for an ISEG is located
within the Administrative Section of TS (Section 6.0). The ISEG
functions in an oversight role and, as such, performs no actions
that would affect any precursors to any accident previously
evaluated. This change does not physically alter safety-related
systems, nor does it affect the way in which safety-related systems
perform their functions. However, the independent oversight
functions and qualification requirements stated in TS are being
performed by qualified personnel in other departments of the VCSNS
organization. This assures that the functions and qualification
requirements delineated for the ISEG are being met. Because the
design of the facility and system operating parameters are not being
changed, and the oversight functions are performed by other
departments, the proposed amendment does not involve an increase in
the probability or consequences of any accident previously
evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
The proposed amendment to delete the ISEG is a programmatic and
administrative change. There are no physical alterations to safety-
related systems and no changes to the functions of any safety-
related systems. The independent oversight functions assigned to the
ISEG are addressed by other departments within the VCSNS
organization. Personnel in those departments meet the qualifications
required of the ISEG. This assures that the oversight functions and
qualification requirements delineated for the ISEG are being met.
Oversight functions that are performed do not in themselves lead to
activities that are considered as accident precursors or initiators.
Because this change does not alter the design of the facility and
system operating parameters are not being changed, and the oversight
functions and qualification requirements of the ISEG are being met
by other departments, the proposed amendment does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. Does this change involve a significant reduction in margin of
safety?
The proposed amendment is a programmatic and administrative
change to

[[Page 65350]]

delete the ISEG. This proposed change involves utilizing
appropriately trained and qualified personnel in other departments
to perform the oversight functions previously assigned to the ISEG.
No physical alterations to safety-related systems and no changes to
the functions of any safety-related systems are being made. The use
of personnel in other departments to perform the oversight functions
of the ISEG will provide assurance that plant operations continue to
be conducted in a safe manner. These oversight functions will be
performed by personnel that maintain their independence from line
operations. Because the design of the facility and system operating
parameters are not being changed, and the oversight functions of the
ISEG are appropriately addressed by other departments and will
continue to be performed, the proposed amendment 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.

Electric Station, Units 1 and 2, Somervell County, Texas

Date of amendment request: September 6, 2000.
Brief description of amendments: The proposed amendment would
change Comanche Peak Steam Electric Station (CPSES), Units 1 and 2,
Technical Specification (TS) 5.5.9, ``Steam Generator Tube Surveillance
Program,'' to permit installation of a laser welded tube sleeve as an
alternative to plugging defective steam generator tubes. TS 5.5.10,
``Steam Generator Tube Inspection Report,'' would be revised to address
reporting requirements for repaired tubes. Also, an editorial
correction is proposed to Table 5.5-2.
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. Do the proposed changes involve a significant increase in the
probability or consequences of an accident previously evaluated?
Response: No.
The tubesheet and/or tube support plate intersection laser
welded sleeve configurations [were] designed and analyzed in
accordance with the requirements of the ASME Code [American Society
of Mechanical Engineers Boiler and Pressure Vessel Code]. Fatigue
and stress analyses of the sleeved tube assemblies produced
acceptable results. Additionally, mechanical testing for the full
length tubesheet sleeves has shown that the structural strength of
Alloy 690 sleeves under normal, faulted, and upset conditions is
within acceptable limits. Leakage testing for these same \3/4\ inch
tube sleeves has demonstrated that primary to secondary leakage is
not expected during any plant conditions. Similar results are
anticipated for the lower joints of elevated tubesheet sleeves.
Confirmatory mechanical and leak testing will be conducted
supporting the installation of elevated tubesheet sleeves at CPSES,
Unit 1.
The hypothetical consequences of failure of a sleeve would be
bounded by the current steam generator tube rupture analysis
included in the Comanche Peak Steam Electric Station (CPSES) Final
Safety Analysis Report (FSAR). Due to the slight reduction diameter
caused by the sleeve wall thickness, it is expected that primary
coolant release rates would be slightly less than assumed for the
steam generator tube rupture analysis (depending on the break
location), and therefore, would result in lower total primary fluid
mass release to the secondary system. Combinations of tubesheet
sleeves and tube support plate sleeves would reduce the primary
fluid flow through the sleeved tube assembly due to the series of
diameter reductions the fluid would have to pass on its way to the
break area. The overall effect would be reduced steam generator tube
rupture release rates. The proposed Technical Specification change
to support the installation of Alloy 690 laser welded sleeves does
not adversely impact any other previously evaluated design basis
accident or the results of (LOCA) [loss-of-coolant accident] and
non-LOCA accident analyses for the current Technical Specification
minimum RCS [reactor coolant system] flow rate.
Conformance of the sleeve design with the applicable sections of
the ASME Code and the successful completion of the leakage and
mechanical tests (for the lower sleeve joint for the elevated
tubesheet sleeves (ETS), support the conclusion that the
installation of laser welded tube sleeves will not increase the
probability or consequences of an accident previously evaluated.
Depending upon the break location for a postulated steam generator
tube rupture event, implementation of tube sleeving could act to
reduce the radiological consequences to the public due to reduced
flow rate through a sleeved tube compared [to] a non-sleeved tube
based on the restriction afforded by the sleeve wall thickness.
The editorial correction [to] Technical Specification (TS) Table
5.5-2 is typographical in nature and does not require additional
evaluation. Therefore, the proposed changes do not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. Do the proposed changes create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
Implementation of the laser welded sleeving (LWS) will not
introduce significant or adverse changes to the plant design basis.
Stress and fatigue analysis of the repair has shown the ASME Code
minimum stress values are not exceeded. Implementation of laser
welded sleeving restores the overall tube bundle structural and
leakage integrity to a level consistent to that of the originally
supplied tubing during all plant conditions. Any hypothetical
accident as a result of potential tube or sleeve degradation in the
repaired portion of the tube is bounded by the existing tube rupture
accident analysis. Finally, through the results obtained from the
extensive testing and qualification program, the possibility of a
common-mode failure, such as multiple simultaneous steam generator
tube failures, is not credible. Therefore, it is concluded that the
proposed changes do not create the possibility of a new or different
kind of accident from any accident previously evaluated.
The editorial correction [to] TS Table 5.5-2 is typographical in
nature and does not require additional evaluation. Therefore, the
proposed change does not create the possibility of a new or
different kind of accident from any previously evaluated.
3. Do the proposed changes involve a significant reduction in a
margin of safety?
Response: No.
The laser welded sleeving repair of degraded steam generated
tubes as identified in References 1 and 2 was shown by analysis to
restore the integrity of the tube bundle consistent with its
original design basis condition. The safety factors used in the
design of sleeves for the repair of degraded tubes are consistent
with the safety factors in the ASME Boiler and Pressure Vessel Code
used in steam generator design. The design of the full length
tubesheet sleeve lower joints for the \3/4\ inch tube sleeves (roll-
first installation sequence) were verified by testing to preclude
pullout and primary-to-secondary leakage during normal and
postulated accident conditions. The qualification of the lower joint
of the TSS [tube support sleeve], ETS and the full length tubesheet
sleeves (FLTS) (roll-last installation sequence) will be confirmed
at the time of the sleeving outage. Since the installed sleeve
represents a portion of the pressure boundary, a baseline inspection
of these areas is required prior to operation with the sleeves
installed. The portions of the installed sleeves assembly which
represent the reactor coolant pressure boundary can be monitored for
the initiation and progression of sleeve/tube wall degradation, thus
satisfying the recommendations of Regulatory Guide 1.83, Rev. 1. The
portion of the tube bridged by the sleeve joints is effectively
removed from the pressure boundary, and the sleeve then forms the
new pressure boundary. The areas of the sleeved tube assembly which
require inspection are defined in WCAP-13698, Rev. 3.
EPRI [Electric Power Research Institute] qualified eddy current
techniques will be used for the detection of tube degradation in \3/
4\ inch laser welded sleeved tubes. Alternate

[[Page 65351]]

inspection techniques may be used as they become available, as long
as it can be demonstrated that the technique used provides the same
degree or greater degree of inspection rigor.
The effect of sleeving on the design transients and accident
analyses were reviewed and found to remain valid up to the level of
steam generator tube plugging consistent with the minimum reactor
flow rate as specified in Technical Specification 3.4.1. Continued
compliance with the RCS flow limits of Technical Specification 3.4.1
is assured through precision flow measurements.
Because all relevant safety analyses were reviewed and found to
remain valid, and because the appropriate design margins are
maintained through compliance with the relevant ASME Code
requirements, it is concluded that the proposed change does not
involve a significant reduction in a margin of safety.
The editorial correction [to] TS Table 5.5-2 is typographical in
nature and does not require additional evaluation. The confirming
modifications to the reporting requirements of TS 5.6.10 are
administrative only. Therefore, these proposed changes do 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.

TXU Electric, Docket Nos. 50-445 and 50-446, Comanche Peak Steam
Electric Station, Units 1 and 2, Somervell County, Texas

Date of amendment request: September 15, 2000.
Brief description of amendments: The proposed change replaces the
general references currently provided in Technical Specification 5.6.6
for determining the reactor coolant system pressure and temperature
limits with the requirement that the Pressure/Temperature Limits and
Low Temperature Overpressure Protection System Setpoints shall not be
revised without prior U.S. Nuclear Regulatory Commission approval.
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. Do the proposed changes involve a significant increase in the
probability or consequences of an accident previously evaluated?
Response: No.
The addition of this requirement to the Technical Specifications
is administrative and has no impact on accident initiation or
mitigation. Therefore, the proposed changes do not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. Do the proposed changes create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The addition of this requirement to the Technical Specifications
is administrative and cannot initiate an accident. Therefore, the
proposed change does not create the possibility of a new or
different kind of accident from any previously evaluated.
3. Do the proposed changes involve a significant reduction in a
margin of safety?
Response: No.
The addition of this requirement to the Technical Specifications
is administrative and has no impact on accident initiation or
mitigation. Therefore the proposed change does not involve 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

Virginia Electric and Power Company, Docket Nos. 50-280 and 50-281,
Surry Power Station, Unit Nos. 1 and 2, Surry County, Virginia

Date of amendment request: September 22, 2000.
Description of amendment request: The proposed changes would remove
obsolete license conditions from the Operating Licenses (OLs) and
implement associated changes to the Technical Specifications (TS) and
Bases. The proposed changes include removal of license conditions
associated with completed facility modifications (including the Steam
Generator (SG) Repair Program, as well as support modifications related
to Leak-Before-Break Technology); removal of superseded license
conditions (addressing security); relocation of secondary water
chemistry monitoring program requirements into the TS; removal of
expired license conditions and TS (addressing service water piping
restoration); and editorial 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, which is presented below:

Virginia Electric and Power Company has reviewed the
requirements of 10 CFR 50.92 as they relate to the proposed
administrative change to the Operating Licenses, DPR-32 and DPR-37,
and the associated Technical Specifications for Surry Units 1 and 2
and determined that a significant hazards consideration is not
involved. The proposed administrative change to the Surry Operating
Licenses and associated Technical Specifications makes minor
editorial corrections, relocates one license condition to Appendix A
of the license, and removes outdated, superceded or otherwise non-
applicable license conditions and Technical Specifications
requirements and provides a license document that is directly
applicable to the current plant licensing and design bases. There is
no safety significance associated with this proposed change since
the change does not alter any currently applicable Operating License
requirements. Accordingly, the current Surry licensing and design
bases are unchanged. In support of this conclusion, the following
evaluation is provided.
Criterion 1--The proposed license amendment does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
The proposed change is administrative (and in part editorial) in
nature and neither station operations nor design are affected by the
change. The removal of license conditions and associated Technical
Specifications regarding superceded (OL Sections 3.H and 3.L) or
expired (OL Section 3.0, TS Table 3.7-2, and TS 3.14) requirements
has no impact on plant operations since the requirements no longer
have a legitimate means of being applied. The relocation within the
Operating License of the requirement to have a secondary water
chemistry monitoring program (OL Section 3.K) to new Section 6.4.P
of the Technical Specifications does not alter the program or its
implementation. The impact of the replacement SGs at Surry and the
re-design of the SG and RCP [reactor coolant pump] supports on the
previously evaluated accidents was performed, approved and
documented by the issuance of the license amendments for OL Sections
3. G and 3.M. Removal of these license conditions which refer to
completed work and a design and licensing bases that is documented
in the UFSAR [updated final safety analysis report] also does not
alter station operation or the design of the affected components.
The proposed change is within the current design and licensing bases
of the facility. This change does not affect the initiators of
analyzed events nor the assumed mitigation of accident or transient
events. Analyzed events are initiated by the failure of plant
structures, systems, or components. This change does not impact the
condition or performance of these structures, systems or components.
Consequences of analyzed events are the result of the plant being

[[Page 65352]]

operated within assumed parameters at the onset of any event, and
the successful functioning of at least one train or division of the
equipment credited with mitigating the event. These changes do not
impact the capability of the credited equipment to perform, nor is
there any change in the likelihood that credited equipment will fail
to perform. As a result, the proposed change to the Surry Operating
Licenses and Technical Specifications does not involve any increase
in the probability or the consequences of any accident or
malfunction of equipment important to safety previously evaluated.
Criterion 2--The proposed license amendment does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
The proposed change is administrative (and in part editorial) in
nature. The license conditions and Technical Specifications that are
being removed or relocated by this proposed change do not impact
station operations or station equipment in any manner. The proposed
change does not involve a physical alteration of the plant, nor a
change in the methods used to respond to plant transients that has
not been previously analyzed. No new or different equipment is being
installed and no installed equipment is being removed or operated in
a different manner. There is no alteration to the parameters within
which the plant is normally operated or in the setpoints, which
initiate protective or mitigative actions. Consequently, no new
failure modes are introduced and the proposed change to the Surry
Operating Licenses and Technical Specifications does not create the
possibility of a new or different kind of accident or malfunction of
equipment important to safety from any previously evaluated.
Criterion 3--The proposed license amendment does not involve a
significant reduction in a margin of safety.
The proposed change is administrative (and in part editorial) in
nature and neither station operations nor design are affected by the
change. Margin of safety is established through the design of the
plant structures, systems and components, the parameters within
which the plant is operated, and the establishment of the setpoints
for the actuation of equipment relied upon to respond to an event.
Since station operations are not affected by the proposed change,
the change does not impact the condition or performance of
structures, systems or components relied upon for accident
mitigation or any safety analysis assumptions. Therefore, the
proposed change to the Surry Operating Licenses and Technical
Specifications does not involve a reduction in any margin of safety
described in the bases of the Technical Specifications.

The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Date of application for amendment: November 1, 1999, and as
supplemented by letter dated May 22, 2000.
Brief description of amendment: Consistent with the guidance of
Generic Letter 99-02, ``Laboratory Testing of Nuclear Grade Activated
Charcoal,'' this amendment modifies existing Technical Specification
