Subject:
Docket Nos. 50-361 and 50-362 Tenth 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 February 23, 1994; Ninth Edition of the Integrated Implementation Schedule (IIS).
Enclosures 1 through 3 provide the Tenth 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 Tisted in the Ninth Edition of the IIS (referenced) for SONGS 2 and 3.
Et; closure T. provides the current Schedule A, B, and C projects for SONGS 2 and 3 fo,- Cydes 7 and 8. lists the ongoing evaluations for major issues for SONGS 2 and 3.
The preliminary Cycle 9 scope of work is still being developed.
It should be included in the Eleventh Edition of the IIS.
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 Tenth Edition of the San Onofre Units 2 and 3 IIS, please let me know.
Very truly yours, Ah N Enclosures I '[ L [ [ [
