NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-272 and 50-311]
Public Service Electric and Gas Company; Salem Nuclear Generating
Station, Units 1 and 2; 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 License Nos.
DPR-70 and DPR-75 issued to Public Service Electric and Gas Company
(the licensee) for operation of the Salem Nuclear Generating Station,
Units 1 and 2, located in Salem County, New Jersey.
The proposed amendment would revise Technical Specification (TS)
3.4.3, ``Relief Valves,'' for Salem Unit 1, and TS 3.4.5, ``Relief
Valves,'' for Salem Unit 2, to ensure that the automatic capability of
the power operated relief valves (PORV) to relieve pressure is
maintained when these valves are isolated by closure of the block
valves.
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--2 -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. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
The proposal does not involve any physical changes to plant
systems or components. No new protection system logic is proposed,
and therefore, there is no additional signal that can spuriously
actuate the Safety Injection (SI) system. Consequently, there would
be no change in the probability of occurrence of the accident, as
previously evaluated in the [Updated Final Safety Analysis Report]
UFSAR. The proposal is based upon a reanalysis of the Inadvertent SI
event to include a case that demonstrates that the postulated event
would not be likely to lead to a more serious event.
Sustained water relief through a PORV can result in a release of
reactor coolant into containment from the Pressurizer Relief Tank.
The release is limited, however, since (1) it is the result of the
SI System addition and consequently cannot exceed the SI flow rate
at the PORV setpoint pressure, and (2) the SI flow will eventually
be terminated by the operators. The dose consequences for an
Inadvertent SI is bounded by that which is calculated for the
spurious opening of a pressurizer safety valve, Accidental RCS
Depressurization event, which is also a Condition II event.
2. The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The Inadvertent Operation of the SI System at Power analysis
cases, reported in the UFSAR, are analyzed to challenge fuel
integrity. Accordingly, the UFSAR analysis cases produce transients
that lead to a reduction in pressurizer pressure, in order to reduce
the thermal margin. The results indicate that no fuel damage is
predicted. The UFSAR analysis is revised in order to evaluate the
effects of an increase in pressurizer pressure and other conditions
that could lead to water relief through the pressurizer safety
valves. Allowing water relief from the pressurizer would not affect
the likelihood of fuel damage occurring during this event. The
results of the accident reanalysis indicate that the pressurizer
safety valves would not discharge water, (a condition for which they
are not designed), and consequently this event will not result in
the failure of a pressurizer safety valve due to the discharge of
water through the pressurizer safety valves.
An evaluation of the effects of water relief through the PORVs
and downstream piping have also been conducted. The results of the
accident reanalysis and the associated evaluation indicate that a
different type of malfunction (e.g., a stuck open pressurizer safety
valve or failure of downstream piping or components) would not be
expected to result from the analyzed event. Therefore, a different
type of accident would not be expected to occur as a result of
implementation of this proposal.
3. The proposed change does not involve a significant reduction
in a margin of safety.
For this proposed change, the safety analysis criterion, which
the analysis of Inadvertent SI Actuation at Power event is required
to satisfy, is to show that the pressurizer safety valves would not
open and discharge water at any time during the event. Satisfaction
of this criterion indicates that the safety margin is preserved by
preventing the Inadvertent Operation of the SI System at Power event
(a Condition II event) from escalating into a more serious event, (a
Condition III event).
The proposal does not reduce the margin of safety, since the
results of the reanalysis indicate that the applicable safety
analysis acceptance criterion, which is established to protect the
margin of safety, is satisfied.
The conclusions of the reanalyzed Inadvertent Operation of the
SI System at Power event are based upon the assumption that the
operators, working according to Emergency Operating Procedures, act
within ten minutes after the event occurs to make at least one
pressurizer PORV available by opening its associated block valve.
This is a justifiable assumption, since simulator test results
indicate that operators have been successful in accomplishing this
procedure within seven to nine minutes and this requirement has been
incorporated into the procedures as a time critical step. Therefore,
relief capability is assured prior to the pressurizer achieving a
solid water condition.
The PORV surveillance requirements that are currently contained
in the Salem TSs ensure that the automatic operation of the PORVs is
periodically tested.
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
[[Page 5862]]
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
Review and Directives Branch, Division of Freedom of Information and
Publications 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 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 March 10, 1997, 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 Salem Free Public Library, 112 West
Broadway, Salem, New Jersey. 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 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: 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 John F. Stolz, Director, Project
Directorate I-2: 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 20555-0001, and to Mark J. Wetterhahn, Esquire, Winston
and Strawn, 1400 L Street, NW., Washington, DC 20005-3502, 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).
