Subject:
Docket Nos. 50-361 and 50-362 Thirteenth Edition of the Integrated Implementation Schedule (IIS)
San Onofre Nuclear Generating Station Units 2 and 3
Reference:
Letter from W. C. Marsh (SCE) to Document Control Desk (NRC),
dated July 17, 1995; Twelfth Edition of the Integrated Implementation Schedule (IIS).
Enclosures 1 and 2 provide the Thirteenth Edition of the Integrated Implementation Schedule (IIS) for the San Onofre Nuclear Generating Station (SONGS), Units 2 and 3. updates the Schedule A, B, and C projects listed in the Twelfth Edition of the IIS (referenced) for SONGS 2 and 3. provides the current Schedule A, B, and C projects for SONGS 2 and 3 for Cycles 8 and 9.
There are no ongoing evaluations of major issues for SONGS 2 and 3.
The Westinghouse Analytical Ranking Program (WARP) was not used to rank the relative safety significance of each Schedule A and B modification because their implementation schedules have been established in separate correspondence.
If you have any questions on the Thirteenth Edition of the San Onofre Units 2 and 3 IIS, please let me know.
Very truly yours, deep' Enclosures cc:
