t 7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION SOUTHERN CALIFORNIA EDISON COMPANY, ET AL.
s DOCKET NOS. 50-361 AND 50-362 NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENTS TO FACILITY OPERATING LICENSES AND OPPORTUNITY FOR HEARING The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of amendments to Facility Operating License Nos. NPF-10 and NPF-15 issued to Southern California Edison Company (SCE), San Diego Gas and Electric Company, the City of Riverside, California and the City of Anaheim, California (the licensees), for operation of San Onofre Nuclear Generating Station, Units 2 and 3 located in San Diego County, California. The request for amendments was submitted by letter dated May 19, 1988 and identified as Proposed Change PCN-246.
TheproposedchangewouldreviseTechnicalSpecification(TS)3/4.7.6,
" Snubbers." TS 3/4.7.6 requires the operability of all snubbers installed on safety related systems or on nonsafety related systems where failure of a snubber or the system could adversely imp.ct a safety related system. TS 3/4.7.6 defines periodic surveillance tests and inspections to verify operability, and actions when a snubber is found to be inoperable. Specifically, TS 4.7.6.b, 4.7.6.d, and 4.7.6.1 require periodic visual inspections, functional tests and service life monitoring of all snubbers.

.s',
TS 4.7.6.b requires a visual inspection of snubbers at a maximum interval of 18 months 25%. The interval for the subsequent visual inspection is decreased, depending on the number of inoperable snubbers detected in the visual inspection, from 12 months 25% if one snubber is inoperable to a minimum of 31 days 25%
if eight or more snubbers are inoperable.
TS 4.7.6.d requires that a representative sample of at least 10% of each type of snubber be functionally tested, either in place or in a bench test, at least once every 18 months, during shutdown. At least 25% of the sample shall include snubbers categorized as the first snubber away from a reactor vessel' nozzle, within five feet of heavy equipment, or witnin ten feet of a safety relief
, valve discharge. Should failures be discovered, functional testing of an addi-l tional 10% is required until no failures are found or all snubbers of that type have been functionally tested.
TS 4.7.6.1 requires that the installation and maintenance records for each snubber be reviewed at least once per 18 months to determine that the service life has not been, and will not be, exceeded until at least the next scheduled
- snubber service life review.
The proposed amendment would make the following changes to the current requirements:
1)
Increase the visual inspection interval from 18 months 25% to 20 months 25% and the subsequent inspection interval for one failure from 12 months 25% to 14' months 25%.
2)
Increase the functional test interval from 18 months to each refueling and increase the functional test sample size from 10% to 15%. For l
-3 consistency, Bases Section 3/4.7.6 would be revised to indicate that functional testing of a representative sample of snubbers is required at refueling intervals.
3)
Increase the interval for snubber service life review from 18 months to refueling interval to be consistent with the functional test interval.
Before issuance of the proposed license amendments, the Commission will have made findings required by the Atomic Energy Act of 1954, as amended (the Act) and the Commission's regulations.
By~ March.21, 1989 the licensees may file a request for a hearing with respect to issuance of the amendments to the subject facility operating licenses, 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 hearing and petition for leave to intervene. Requests for a hearing and petitions 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.
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 Panel 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 fe: lowing factors:
(1)thenature of the petitioner's right under the Act to be made a 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 fifteen (15) days prior to the first pre-hearing conference schedule in the proceeding, but such an amended petition must satisfy the specificity requirements described above.
Not later than fifteen (15) days prior to the first pre-hearing 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, and the bases for each contention set forth with reasonable specificity. Contentions shall be limited to matters within the scope of the amendments under consideration. 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.
A request for a hearing or a petition for leave to intervene shall be filed
