NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-445 and 50-446]
Texas Utilities Electric Co.; 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 Nos.
NPF-87 and NPF-89 issued to Texas Utilities Electric Company (TU
Electric, the licensee) for operation of the Comanche Peak Steam
Electric Station, Units 1 and 2 located in Somervell County, Texas.
The proposed amendment would modify the Comanche Peak Steam
Electric Station (CPSES) Technical Specification (TS) 3/4.6.2,
``Depressurization and Cooling Systems--Containment Spray System''
Surveillance Requirement (SR) 4.6.2.1b, is replaced with NUREG-1431 SR
3.6.6A.4. This change replaces the specific pump flow and head values
now contained in the SR with the general requirement that the pump
develop the required head at the flow test point. Also Bases 3/4.6.2.1
``Containment Spray System'' will be revised to expand the detail
consistent with the NUREG-1431 Bases SR 3.6.6A.4. The Bases from NUREG-
1431 has minor modifications to reflect (1) that the CPSES containment
spray pumps are tested via a special test line which allows testing at
flows higher than that allowed by the miniflow recirculation line; (2)
the ``pump design curve'' is termed the ``analytical pump curve''; and
(3) the reference to the technical requirements manual where the pump
head requirements are defined is provided for the user's information.
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 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:
1. Do the proposed changes involve a significant increase in the
probability or consequences of an accident previously evaluated?
The relocation of the specific values for flow and developed
head at the flow test point to the Technical Requirements Manual
(TRM) is essentially an administrative change. The change does not
change the plant hardware or operating procedures. As such, the
change has no impact on the probability of an accident.
The consequences of an accident previously evaluated, as it
relates to the performance characteristics of the containment spray
pumps, depends on the pumps meeting the performance characteristics
in the analytical pump curve used by the containment analyses. Since
the limitations established in the TRM will continue to ensure that
this analytical pump curve is met, there is no impact on the
[[Page 12256]] accident analyses. The initial TRM will duplicate the
existing surveillance values. In the future, the TRM values may be
slightly more or slightly less restrictive based on changes to the
containment analyses or their design inputs. The result of this
variation could be a minor variation in the consequences of an
actual event were one to occur; however, the consequences would be
bounded by the existing safety analyses and therefore, the change
does not involve a significant increase in the consequences of an
accident previously evaluated.
2. Do the proposed changes create the possiblity of a new or
different kind of accident from any accident previously evaluated?
The proposed change does not add new hardware to the units or
change plant operations. Relocation of the surveillance acceptance
criteria to the TRM cannot initiate an event nor cause an analyzed
event to progress differently. Thus, the possibility of a new or
different kind of accident is not created.
3. Do the proposed changes involve a significant reduction in a
margin of safety?
The margin of safety is not affected since the surveillance will
continue to be required by Techincal Specifications at the same
frequency and that surveillance will continue to ensure the
containment spray pump performance is bounded by the analytical pump
curve used in the containment analyses.
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 Rules Review and
Directives Branch, Division of Freedom of Information and Publications
Services, Office of Aministration, U.S. Nuclear Regulatory Commission,
Washington, DC 20555, and should cite the publication date and page
number of this Federal Register notice. Written comments may also be
delivered to Room 6D22, Two White Flint North, 11545 Rockville Pike,
Rockville, Maryland, from 7:30 a.m. to 4:15 p.m. Federal workdays.
Copies of written comments received may be examined at the NRC Public
Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC.
The filing of requests for hearing and petitions for leave to
intervene is discussed below.
By April 5, 1995, 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, the Gelman
Building, 2120 L Street, NW., Washington, DC, and at the local public
document room located at the University of Texas at Arlington Library,
Government Publications/Maps, 702 College, P.O. Box 19497, Arlington,
Texas 76019. 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 petitioners shall file a supplement to
the petition to intervene which must incude 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. [[Page 12257]]
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, 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. Where petitions are filed during the last 10 days of the notice
period, it is requested that the petitioner promptly so inform the
Commission by a toll-free telephone call to Western Union at 1-(800)
248-5100 (in Missouri 1-(800) 342-6700). The Western Union operator
should be given Datagram Identification Number N1023 and the following
message addressed to William D. Beckner, Director, Project Directorate
IV-1: petitioner's name and telephone number, date petition was mailed,
plant name, and publication date and page number of this Federal
Register notice. A copy of the petition should also be sent to the
Office of the General Counsel, U.S. Nuclear Regulatory Commission,
Washington, DC 20555, and to George L. Edgar, Esq., Newman and
Holtzinger, 1615 L Street, N.W., Washington, D.C. 20036, 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 28, 1995, which is available
for public inspection at the Commission's Public Document Room, the
Gelman Building, 2120 L Street, NW., Washington, DC, and at the local
public document room located at the University of Texas at Arlington
Library, Government Publications/Maps, 702 College, P.O. Box 19497,
Arlington, Texas 76019.
