UNITED STATES NUCLEAR REGULAT RY OMMI ION PPSL INC.
DOCKET N
. 50-388 NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENTTO FACILITYOPERATING LICENSE PR POSED NO SIGNIFICANTHAZARDS CONSIDERATION DETERMINATION AND OPPORTUNITY FOR A HEARING The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Facility Operating Ucense No. 22 issued to PPBL, Inc. (the licensee) for operation of the Susquehanna Steam Electric Station (SSES), Unit 2, located in Luzerne County, Pennsylvania.
This notice supersedes the previous notice published on Spetember 9, 1998, (63 FR 48263) in its entirety. The proposed amendment would change the allowable values for both t
the core spray system and low pressure coolant injection system reactor steam dome pressure low functions.
Before issuance of the proposed license amendment, the Commission willhave 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 facilityin accordance with the proposed amendment would not (1) involve a sign Tiicant 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 990i290346 990i27 PDR ADOCK 05000388
~P PDR
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:
The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
-This proposal does not involve an increase in the probability or consequences of an accident previously evaluated.
The proposed amendment changes the "Reactor Steam Dome Pressure-Low" Allowable Values so to provide further assurance that the Core Spray and RHR systems willperform their LOCA design basis function.
The functional design basis of the Core Spray and LPCI is to inject water into the reactor vessel to cool the core during a LOCA by opening the core Spray and LPCI injection valves when reactor pressure drops below the reactor vessel low pressure permissive.
The upper analytical limitfor the permissive is the Core Spray and LPCI systems'aximum design pressure, and the lower analytical limit is the lowest pressure which allows injection to prevent exceeding the fuel cladding temperature limit. The new allowable values were selected to lie within the upper and lower limits to ensure there willbe no change in the required logic or functions of the Core Spray and LPCI systems.
These new values do not affect the LOCA or its "limitingfault" frequency of occurrence and do not introduce any new accidents or malfunctions of equipment important to safety.
Since they do not affect the LOCA, they do not change the probability of occurrence of the LOCA. The new allowable values do not change the logic or function of the reactor vessel low pressure permissive.
These new allowable values simply provide the basis for which the associated pressure instruments are to be set to ensure proper operation of Core Spray and LPCI within the design pressures as described above.
Therefore, the change in allowable values does not increase the probability of occurrence or the consequences of an, accident or malfunction of equipment important to safety.
t Based upon the analysis presented above, PP8L concludes that the proposed action does not involve an increase in the probability or consequences of an accident previously evaluated.
The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
This proposal does not create the probability of a new or different type of accident from any accident previously evaluated.
The new allowable values do not change any plant systems, structures, or components, nor do they change any existing or created any new Core Spray and LPCI logic or functions. The new allowable
. values were selected to ensure the required operation of the Core Spray and LPCI systems within the design pressures described above.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed change does not involve a significant reduction in the margin of safety.
~
'I The change does not involve a reduction in the margin of safety. Technical.
Specification Bases Section B3.3.5.1 9 (ECCS Instrumentation) identifies that the low reactor steam dome pressure signals are used as permissives for operation of the low pressure ECCS sybsystems.
The new allowable values were selected so to not impact the logic, redundancy, operability or surveillance requirements for these subsystems.
The new allowable values maintain the margin requirements that the Core spray and LPCI system pressures such that they do not exceed their system maximum design pressures and that system pressures are high enough to ensure that the ECCS injection prevents the fuel peak cladding temperature from exceeding the limits of 10CFR50.46.
The margin of safety is unaffected by the proposed changes.
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 willbe considered in making any final determination.
Normally, the Commission willnot 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 willconsider all public and State comments received.
Should the Commission take this action, itwillpublish in the FEDERAL REGISTER a notice of issuance and provide for opportunity for a hearir'ig after issuance.
The Commission expects that the need to take this action willoccur 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 Regulatoiy 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.
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 Nqi-ch 3, 1 g g g, the licensee may file a request for a hearing with respect to issuance of the amendment to the subject facilityoperating 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 Osterhout Free Library, Reference Department, 71 South Franklin Street, Wilkes-Barre, PA 18701.
Ifa request for a hearing or
~
'v 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, willrule on the request and/or petition; and the Secretary or the
'designated Atomic Safety and Licensing Board willissue 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
'v 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, ifproven, would entitle the petitioner to relief. A petitioner who fails to fite such a supplement which satisfies these requirements with respect to at least one contention willnot 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 willmake a final determination on the issue of no significant hazards consideration.
The final determination willserve to decide when the hearing is held.
Ifthe 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.
Ifthe final determination is that the amendment request involves a significant hazards consideration, any hearing held would take place before the issuance of any amendment.
