Subject:
Docket Nos. 50-361 and 50-362 Eleventh 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 11, 1994; Tenth Edition of the Integrated Implementation Schedule (IIS).
Enclosures 1 through 3 provide the Eleventh 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 Tenth 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 7, 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 Eleventh Edition of the San Onofre Units 2 and 3 IIS, please let me know.
Very truly yours,
