NUCLEAR REGULATORY COMMISSION
[Docket No. 50-327]
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 (NRC or the Commission) is
considering issuance of an amendment to Facility Operating License DPR-
77 issued to the Sequoyah Nuclear Plant (SQN) for operation of Unit 1
located in Hamilton County, Tennessee.
The proposed amendment would revise the SQN, Unit 1, Updated Final
Safety Analysis Report (UFSAR). The revision provides an alternative
methodology using a Bar-Lock Mechanical Splice in lieu of the Cadweld
splice used in the original design and construction of the Unit 1
concrete shield building dome. This proposed Bar-Lock mechanical splice
is described in Topical Report No. 24370-TR-C-001, ``Alternate Rebar
Splice--Bar-Lock Mechanical Splices,'' and is requested for
implementation upon the restoration of the dome as part of the upcoming
steam generator replacement project for SQN, Unit 1.
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 amendment
request involves no significant hazards consideration. Under the
Commission's regulations in title 10 of the Code of Federal Regulations
(10 CFR), section 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:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
No. No changes in event classification, as discussed in UFSAR
chapter 15, will occur due to use of the Bar-Lock couplers.
The restoration of the temporary concrete construction openings
in the shield building will utilize Bar-Lock couplers to splice new
rebar to the existing rebar. The shield building structure limits
the release of radioactivity following an accident and protects the
systems, structures, and components inside containment from external
events. The accidents of interest are those that rely on the shield
building to limit the release of radioactivity to the environment,
and those that result from some external events. The design of the
shield building is such that it is not postulated to fail and
initiate an accident described in the UFSAR.
The Bar-Lock coupler qualification tests detailed in Topical
Report 24370-TR-C-001 demonstrate that the Bar-Lock coupler meets
the American Society of Mechanical Engineers (ASME) strength
requirements and is, therefore, acceptable for use in nuclear
safety-related applications. Based on these test results, it is
concluded that use of the Bar-Lock couplers in restoring the
temporary
[[Page 12719]]
concrete construction openings will not reduce the structural
capability of the repaired structure. The shield building will
continue to perform its design function as described in the SQN
UFSAR.
Therefore, the proposed use of the Bar-Lock couplers will not
significantly increase the probability or consequences of an
accident previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
No. The design of the shield building is such that it is not
postulated to fail and initiate an accident described in the UFSAR.
The Bar-Lock couplers are passive devices and as such will not
initiate or cause an accident.
The restoration of the temporary concrete construction openings
in the shield building will utilize Bar-Lock couplers to splice new
rebar to the existing rebar. The Bar-Lock coupler qualification
tests detailed in Topical Report 24370-TR-C-001 demonstrate that the
Bar-Lock coupler meets the ASME strength requirements and is,
therefore, acceptable for use in nuclear safety-related
applications. Based on these test results, it is concluded that use
of the Bar-Lock couplers in restoring the temporary concrete
construction openings will not reduce the structural capability of
the shield building. The shield building will, therefore, continue
to perform its design functions as described in the SQN UFSAR.
Therefore, the possibility of a new or different accident
situation occurring as a result of this condition is not created.
3. Does the proposed change involve a significant reduction in a
margin of safety?
No. As indicated in the SQN UFSAR, the structural design of the
shield building is in compliance with the American Concrete
Institute (ACI) 318-63 building code working stress design
requirements. The reinforcing steel conforms to the requirements of
ASTM (American Society for Testing and Materials) A 615, Grade 60.
The SQN UFSAR states that reinforcing bars were lap spliced in
accordance with ACI 318-63 requirements for Strength Design.
The restoration of the temporary concrete construction openings
in the shield building will utilize Bar-Lock couplers to splice new
rebar to the existing rebar. The restoration of the construction
openings, including use of the Bar-Lock couplers, will conform to
the requirements of ACI 318. Therefore, following completion of the
modification, the shield building will continue to comply with ACI
318 requirements.
In addition to conforming to ACI 318 requirements, the Bar-Lock
coupler qualification tests detailed in Topical Report 24370-TR-C-
001 demonstrate that the Bar-Lock coupler meets the ASME strength
requirements.
Therefore, a significant reduction in the margin to safety is
not created by this modification.
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, Public File Area O1 F21, 11555
Rockville Pike (first floor), Rockville, Maryland.
The filing of requests for hearing and petitions for leave to
intervene is discussed below.
By April 16, 2003, 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,\1\ which is
available at the Commission's Public Document Room, located at One
White Flint North, 11555 Rockville Pike (first floor), Rockville,
Maryland, or electronically on the Internet at the NRC Web site http://www.nrc.gov/reading-rm/doc-collections/cfr/. If there are problems in
accessing the document, contact the Public Document Room Reference
staff at 1-800-397-4209, 301-415-4737, or by e-mail to [email protected]. 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.

\1\ The most recent version of title 10 of the Code of Federal
Regulations, published January 1, 2002, inadvertently omitted the
last sentence of 10 CFR 2.714(d) and subparagraphs (d)(1) and (2),
regarding petitions to intervene and contentions. For the complete,
corrected text of 10 CFR 2.714(d), please see 67 FR 20884; April 29,
2002.
---------------------------------------------------------------------------
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
[[Page 12720]]
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: Rulemakings and
Adjudications Staff, or may be delivered to the Commission's Public
Document Room (PDR), located at One White Flint North, Public File Area
O1 F21, 11555 Rockville Pike (first floor), Rockville, Maryland, by the
above date. Because of the continuing disruptions in delivery of mail
to United States Government offices, it is requested that petitions for
leave to intervene and requests for hearing be transmitted to the
Secretary of the Commission either by means of facsimile transmission
to 301-415-1101 or by e-mail to [email protected]. A copy of the
petition for leave to intervene and request for hearing should also be
sent to the Office of the General Counsel, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001, and because of continuing
disruptions in delivery of mail to United States Government offices, it
is requested that copies be transmitted either by means of facsimile
transmission to 301-415-3725 or by e-mail to [email protected]. A
copy of the request for hearing and petition for leave to intervene
should also be sent to General Counsel, Tennessee Valley Authority, 400
West Summit Hill Drive, ET 11A, 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 February 14, 2003, which is available
for public inspection at the Commission's PDR, located at One White
Flint North, File Public Area O1 F21, 11555 Rockville Pike (first
floor), Rockville, Maryland. Publicly available records will be
