NUCLEAR REGULATORY COMMISSION
[Docket Nos. STN 50-456 and STN 50-457]
Commonwealth Edison Company; Notice of Consideration of Issuance
of Amendments to Facility Operating Licenses, Proposed No Significant
Hazards Consideration Determination, and Opportunity for a Hearing
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of amendments to Facility Operating Licenses Nos.
NPF-72 and NPF-77 issued to the Commonwealth Edison Company (the
licensee) for operation of the Braidwood Station, Units 1 and 2,
located in Will County, Illinois.
The proposed amendment would revise the Technical Specifications
for Braidwood 1 and 2 by deleting Section 4.7.6.e.6 which presently
requires a surveillance to verify that the control room ventilation
system can be manually isolated and placed in the recirculation mode of
operation. This manual isolation would be initiated in response to a
report of a chlorine release in the vicinity of the Braidwood Station.
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:
A. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
Elimination of the requirement to test control room ventilation
manual isolation capability does not involve a significant increase
in the probability or consequences of an accident previously
evaluated. This requirement had been previously necessary because of
the potential of a rail borne chlorine accident. Since that time of
the imposed surveillance, the Norfolk and Western railroad line
which transported chlorine near Braidwood has been removed. In
addition, a study has concluded that there are no potential
stationary chlorine release sources within a 10 mile radius that
could pose a threat to control room habitability. The evaluation
concluded that the realistic probability of a transported source of
chlorine passing within the critical distance of 4900 feet of
Braidwood Station is practically zero. Even using the very
conservative assumption that all transported sources of chlorine use
IL 53 or IL 129, the occurrence of an accidental release from these
shipments was calculated to be only 2 x 10-6 events per year.
Thus the probability of a chlorine release is within the
requirements of NUREG-0800, Standard Review Plan (SRP), July 1981
Section 2.2.3, and removal of the requirement to conduct Control
Room ventilation isolation tests every 18 months does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
To ensure that no potential stationary chlorine release source
is introduced within a ten mile radius of Braidwood Station, the
station will perform a survey every three years to ensure that the
protection of the control room personnel from risk due to any
potential chlorine accident is maintained sufficiently small.
B. The proposed changes does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The probability of a chlorine accident that could impact the
control room environment has been shown to be within the
requirements of SRP Section 2.2.3. Control Room isolation capability
testing was performed only to address a chlorine accident.
Therefore, removal of this requirement does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
C. The proposed changes does not involve a significant reduction
in a margin of safety.
Control room ventilation isolation testing was performed as a
result of the possibility of a chlorine accident in the vicinity of
Braidwood. As demonstrated by a recent study, the probability of
this event occurring has been reduced to practically zero within the
acceptable limits of SRP Section 2.2.3 for transportable chlorine.
Survey of the ten mile radius around Braidwood found no stationary
chlorine sources with large enough quantities to pose a hazard to
control room personnel. Thus, the removal of the requirement to
perform Control Room ventilation isolation tests every 18 months
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.
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 [[Page 4931]] 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 Administration, 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 February 24, 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 Wilmington Township Public Library, 201 S.
Kankakee Street, Wilmington, Illinois 60481. 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
proceedings; 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, 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 Robert A. Capra: 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 Michael I. Miller,
Esquire; Sidley and Austin, One First National Plaza, Chicago, Illinois
60690, attorney for the licensee.
Nontimely filings of petitions for leave to intervene, amended
petitions, supplemental petitions and/or requests [[Page 4932]] 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).
