NUCLEAR REGULATORY COMMISSION
[Docket No. 50-390]
Tennessee Valley Authority; Notice of Consideration of Issuance
of Amendment to Facility Operating License, Proposed No Significant
Hazards Consideration Determination, and Opportunity for a Hearing
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of an amendment to Facility Operating License No.
NPF-90, issued to the Tennessee Valley Authority (TVA, the licensee),
for operation of the Watts Bar Nuclear Plant (WBN), Unit 1, located in
Rhea County, Tennessee.
The proposed amendment would modify the WBN Technical
Specifications (TS) to allow a one-time-only increase in the diesel
generator Action Completion Time from 72 hours to 10 days. This
allowance would facilitate potential repairs to an emergency diesel
generator to improve reliability.
Before issuance of the proposed license amendment, the Commission
will have made findings required by the Atomic Energy Act of 1954, as
amended (the Act) and the Commission's regulations.
The Commission has made a proposed determination that the
[[Page 66267]]
amendment request involves 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. 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:
(A) The proposed amendment does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
The diesel generators are designed as backup AC power sources in
the event of loss of offsite power. The probability of occurrence of
an accident is not increased as the diesel generators perform a
function of accident mitigation only and cannot cause an accident.
Similarly, the diesel generator itself would be out of service and
could not cause other equipment to malfunction.
The technical specifications currently would allow two emergency
diesel generators of one train to be out of service for up to three
days followed consecutively by two diesel generators of the opposite
train to be out of service for three more days. Thus, the current
specifications would allow two diesels to be unavailable for six
days total. This proposed change would allow a single diesel
generator to be out of service for ten days. This is not considered
to be a significant departure from the current requirement. Further,
the consequences of postulated accident with one diesel generator
unavailable is enveloped by the current allowance for both trained
generators unavailable.
The cumulative consequences of an accident are not significantly
increased as the increase in core damage frequency as a result of
the additional Action Completion Time extension is non-risk
significant. Therefore, the proposed amendment does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
(B) The proposed amendment does not create the possibility of a
new or different kind of accident from any accident previously
evaluated.
The possibility for a new or different kind of accident from any
accident previously evaluated does not exist as a result of the
increase in Action Completion Time for the diesel generator, as the
diesel generator performs a function of accident mitigation only and
cannot result in the malfunction of other equipment while undergoing
repairs.
(C) The proposed amendment does not involve a significant
reduction in a margin of safety.
The calculated increase in the Action Completion Time for one
diesel generator out of service shows a non-risk significant
increase in the predicted core damage frequency (CDF). TVA concludes
that the margin of safety has not been reduced.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.
The 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.
Should the Commission take this action, it will publish in the Federal
Register a notice of issuance and provide for opportunity for a hearing
after issuance. The Commission expects that the need to take this
action will occur very infrequently.
Written comments may be submitted by mail to the Chief, Rules and
Directives Branch, Division of Administrative Services, Office of
Administration, U.S. Nuclear Regulatory Commission, Washington, DC
20555-0001, and should cite the publication date and page number of
this Federal Register notice. Written comments may also be delivered to
Room 6D59, Two White Flint North, 11545 Rockville Pike, Rockville,
Maryland, from 7:30 a.m. to 4:15 p.m. Federal workdays. Documents may
be examined, and/or copied for a fee, at the NRC's Public Document
Room, located at One White Flint North, 11555 Rockville Pike (first
floor), Rockville, Maryland.
The filing of requests for hearing and petitions for leave to
intervene is discussed below.
By December 4, 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, and accessible electronically through the ADAMS Public
Electronic Reading Room link at the NRC Web site (http://www.nrc.gov).
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 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 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
[[Page 66268]]
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: Rulemakings and
Adjudications Staff, or may be delivered to the Commission's Public
Document Room, located at One White Flint North, 11555 Rockville Pike
(first floor), Rockville, Maryland, 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
General Counsel, Tennessee Valley Authority, ET 10H, 400 East Summit
Hill Drive, Knoxville, Tennessee 37902, attorney for the licensee.
Nontimely filings of petitions for leave to intervene, amended
petitions, supplemental petitions and/or requests for hearing will not
be entertained absent a determination by the Commission, the presiding
officer or the presiding Atomic Safety and Licensing Board that the
petition and/or request should be granted based upon a balancing of the
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 dated October 30, 2000, which is available
for public inspection at the Commission's Public Document Room, located
at One White Flint North, 11555 Rockville Pike (first floor),
Rockville, Maryland, and accessible electronically through the ADAMS
Public Electronic Reading Room link at the NRC Web site (http://www.nrc.gov).
Dated at Rockville, Maryland, this 30th day of October 2000.
