An ED50N INTM%ATIONAL* Company May 11, 1998 U. S. Nuclear Regulatory Commission Attention: Document Control Desk Washington, D.C. 20555 Gentlemen:
Subject:
Docket Nos. 50-361 and 50-362 Supplement 1 to Amendment Application Nos.161 and 145 Appendix J. Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors, Option B San Onofre Nuclear Generating Station Units 2 and 3

Letter dated May 30, 1996, from Dwight E. Nunn (SCE) to Document Control Desk (NRC),
Subject:
Docket Nos. 50-361 and 50-362, Amendment Application Nos.161 and 145, Appendix J, Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors, Option B San Onofre Nuclear Generating Station, Units 2 and 3 Enclosed is Supplement 1 to Amendment Application Numbers 161 and 145 to Facility Operating Licenses NPF-10 and NPF-15 for San Onofre Nuclear Generating Station (SONGS) Units 2 and 3, respectively. Supplement 1 to these amendment applications supersedes entirely the applications forwarded by the Reference letter, which are hereby withdrawn.
These amendment applications consistofProposedTechnicalSpecificationChangeNumberNPF-10/15-468(PCN 468), Supplement 1.
PCN 468, Supplement 1, requests changes to Surveillance Requirements (SRs) 3.6.1.1, SR 3.6.2.1, and SR 3.6.3.6, and creates a new Technical Specification 5.5.2.14.
The affected Bases sections are provided for information only.
The original PCN 468 (Reference) was a request to allow implementation of the recently approved Option B to 10 CFR Part 50, Appendix J.
This new rule allows for a performance-based option for determining the test frequency for containment leakage rate testing. The original PCN 468 requested changes to the SONGS Units 2 and 3 Technical Specifications (TSs) which replaced the references to " Appendix J, as modified by approved exemptions" with
" Appendix J, Option B, as modified by approved exemptions and Regulatory Guide 1.163, dated September, 1995."

Document Control Desk Supplement 1 to PCN 468 is being submitted to re-format the request consistent with Standard Technical Specification Change Traveler TSTF-52.
PCN 468, Supplement 1, is a request to create a Containment Leakage Rate Testing Program, which will be incorporated into the proposed TS 5.5.2.14.
All acceptance criteria and surveillance frequencies currently found in the affected SRs and associated Bases will be relocated to the Containment Leakage Rate Testing Program. Supplement I changes are marked with change bars to show the differences from the original PCN 468.
In accordance with existing requirements, an Integrated Leak Rate Test (ILRT)
}
will be required during the Units 2 and 3 Cycle 10 refueling outages.
This ILRT would not be required in accordance with Option B of Appendix J.
The Unit 2 Cycle 10 refueling outage is currently scheduled to begin on January 2, 1999.
However, planning efforts for the ILRT need to begin as early as six months before the beginning of the outage.
In addition, there are Local Leak Rate Tests (LLRTs) currently required to be performed beginning on November 18, 1998, which would not be required under Option B of Appendix J.
These LLRTs would involve an unnecessary shutdown or a power entry into containment.
Therefore, Southern California Edison requests approval of this proposed change no later than November 1, 1998, to be implemented within 30 days of 4
issuance.
