NUCLEAR REGULATORY COMMISSION
[Docket No. 50-259]
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.
DPR-33 issued to the Tennessee Valley Authority (TVA) for operation of
the Browns Ferry Nuclear Plant (BFN), Unit 1 located in Limestone
County, Alabama.
The proposed amendment would delete the Technical Specification
(TS) Surveillance Requirement (SR) to verify the position of a low
pressure coolant injection (LPCI) crosstie valve. 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 Technical Specification change involve a
significant increase in the probability or consequences of an
accident previously evaluated?
Response: No. This TS change is administrative in nature, since
it deletes the surveillance requirement (SR 3.5.1.4) to periodically
verify the position of a valve which has now been physically removed
from Unit 1. Originally, BFN's LPCI design included the capability
for the redundant LPCI loop discharge piping to be cross-tied;
however, subsequent analysis determined that the crosstie
capability, under certain accident and single-failure scenarios,
could result in the loss of injection from both LPCI loops. This
analysis also determined that the crosstie capability was not
required for the mitigation of any design basis events. Accordingly,
since certain crosstie failure modes could prevent mitigation of
these or other events, TVA modified the plant design to eliminate
the crosstie capability. This was accomplished by closing and
deenergizing the motor-operated isolation valve that existed in the
crosstie flow path and adding an SR to require periodic verification
that the valve was closed and deenergized.
The modified Unit 1 configuration [i.e., LPCI loop discharge
crosstie valve removed and the associated remaining piping capped or
closed with a blind flange] eliminates the possibility of an
undesired flow path. Additionally, the Seismic Class I qualification
and the ASME Section XI classification of the remaining piping in
the new plant configuration are equivalent to the replaced line
configuration. Accordingly, the TS change does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. Does the proposed Technical Specification change create the
possibility of a new or different kind of accident from any accident
previously evaluated?
Response: No. The physical modification eliminating the LPCI
loop discharge crosstie capability does not require revision of the
safety analyses. In addition, since the LPCI loop crosstie valve has
been physically removed from the system and the associated lines
capped or closed via blind flange, the possibility for inadvertent
flow between the LPCI loops has been eliminated. Removing the valve
and capping/flanging the remaining piping is an improvement over the
old configuration. The LPCI function will be accomplished in the
same way as before the modification, and no new failure modes have
been introduced.
3. Does the proposed Technical Specification change involve a
significant reduction in a margin of safety?
Response: No. This TS changes does not involve a reduction in
the margin of safety since removal of the LPCI loop cross tie valve
eliminates the possibility of flow between the two LPCI loops, and
it obviates the need for valve position verification contained in
the SR. In addition, since removing the valve and capping/flanging
the residual piping meets the intent of the SR, the safety analysis
remains unchanged.
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 60 days after the date of publication of this notice. The
Commission may issue the license amendment before expiration of the 60-
day period provided that its final determination is that the amendment
involves no significant hazards consideration. In addition, the
Commission may issue the amendment prior to the expiration of the 30-
day comment period should circumstances change during the 30-day
comment period such that failure to act in a timely way would result,
for example, in derating or shutdown of the facility. Should the
Commission take action prior to the expiration of either the comment
period or the notice period, it will publish in the Federal Register a
notice of issuance. Should the Commission make a final No Significant
Hazards Consideration Determination, any hearing will take place 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, Rulemaking,
Directives and Editing 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 (PDR), 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.
Within 60 days after the date of publication of this notice, 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
[[Page 67167]]
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 2.309, which is
available at the Commission's PDR, located at One White Flint North,
Public File Area O1F21, 11555 Rockville Pike (first floor), Rockville,
Maryland. Publicly available records will be accessible from the
Agencywide Documents Access and Management System's (ADAMS) Public
Electronic Reading Room on the Internet at the NRC Web site, http://www.nrc.gov/reading-rm/doc-collections/cfr/. If a request for a hearing
or petition for leave to intervene is filed by the above date, the
Commission or a presiding officer designated by the Commission or by
the Chief Administrative Judge of the Atomic Safety and Licensing Board
Panel, will rule on the request and/or petition; and the Secretary or
the Chief Administrative Judge of the Atomic Safety and Licensing Board
will issue a notice of a hearing or an appropriate order.
As required by 10 CFR 2.309, 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 general requirements: (1) The name, address and telephone
number of the requestor or petitioner; (2) the nature of the
requestor's/petitioner's right under the Act to be made a party to the
proceeding; (3) the nature and extent of the requestor's/petitioner's
property, financial, or other interest in the proceeding; and (4) the
possible effect of any decision or order which may be entered in the
proceeding on the requestors/petitioner's interest. The petition must
also identify the specific contentions which the petitioner/requestor
seeks to have litigated at the proceeding.
Each contention must consist of a specific statement of the issue
of law or fact to be raised or controverted. In addition, the
petitioner/requestor shall provide a brief explanation of the bases for
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/requestor 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.
The petition must include 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/requestor
who fails to satisfy 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.
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.
Nontimely requests and/or petitions and contentions will not be
entertained absent a determination by the Commission or the presiding
officer of the Atomic Safety and Licensing Board that the petition,
request and/or the contentions should be granted based on a balancing
of the factors specified in 10 CFR 2.309(c)(1)(i)-(viii).
A request for a hearing or a petition for leave to intervene must
be filed by: (1) First class mail addressed to the Office of the
Secretary of the Commission, U.S. Nuclear Regulatory Commission,
