20555 Gentlemen:
Subject:
Docket Nos. 50-361 and 50-362 Twelfth Edition of the Integrated Implementation Schedule (IIS)
San Onofre Nuclear Generating Station Units 2 and 3 1
Reference:
Letter from W. C. Marsh (SCE) to Document Control Desk (NRC),
i dated December 29, 1994; Eleventh Edition of the Integrated Implementation Schedule (IIS).
Enclosures 1 through 3 provide the Twelfth Edition of the Integrated i
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 Eleventh 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. lists the ongoing evaluations for 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 Twelfth Edition of the San Onofre Units 2 and 3 IIS, please let me know.
Very truly yours, 9alb8 Enclosures l
