ENCLOSURE INTEGRATED IMPLEMENTATION SCHEDULE SAN ONOFRE NUCLEAR GENERATING STATION, UNIT 1 ELEVENTH EDITION JUNE 1991 Introduction License Condition 3.J, "Integrated Implementation Schedule" (IIS), requires Southern California Edison (SCE) to follow the IIS Program Plan issued in License Amendment No. 98 on April 20, 1987.Section V.A of the Plan states that SCE will update Schedules A, B, and C semi-annually. Schedule A items have implementation dates required by NRC regulations, orders or license conditions. Schedule B items are other items which have implementation dates committed to by SCE which would result in either:
(a)
Plant modifications; (b)
Procedure revisions; (c)
Changes in facility staffing requirements; (d) Items perceived by SCE as prospective NRC requirements; (e) Major tasks resulting from mandates of agencies other than the NRC; or (f) Evaluation of major NRC-initiated issues not required by Regulation, License Conditions, or Orders Schedule C lists SCE initiated plant betterment projects. The Plan also states that SCE will summarize progress in implementing NRC requirements concerning plant modifications; identify changes since the last report; summarize the reasons for schedule changes associated with Schedules A and B; and, indicate the expected percentage allocation of resources on Regulatory and Betterment projects for the next refueling/modification outage.
This report, the eleventh edition of the IIS, provides the required status update for the period December 1990 through May 1991. The tenth edition of the IIS was provided to the NRC by letter, F. R. Nandy to NRC Document Control Desk, dated December 27, 1990.
The current Schedules A, B, and C are enclosed as Attachments 1, 2 and 3, respectively.
Progress In Implementing NRC Requirements Since the last submittal (IIS Tenth Edition) in December 1990, Unit 1 concluded the Cycle 11 refueling outage on March 23, 1991.
All of the modifications reported for Cycle 11 in the Tenth Edition of the IIS have been completed except the Boric Acid Gas System Modifications. We encountered difficulties in the installation of this DCP and provided status on this item in our Full Term Operating License (FTOL) update letter dated February 22, 1991.
This letter stated that we would provide a completion

- 2 schedule with this edition of the IIS. Currently, we forecast completion of this DCP for October 31, 1991.
All of the remaining Schedule A and B modification work reported in this edition of the IIS for the Cycle 12 refueling outage will be completed in the Cycle 12 refueling outage.
Changes Since The Last Report And The Reasons For Schedule Changes Associated With Schedules A and B.
A comparison to the tenth edition of the IIS reveals that the following changes have occurred to the Cycle 12 schedule:
Action Cycle Schedule Modification Deleted 12 C
Turbine Plant Cooling Water (TPCW)
Upgrades - Completed Schedule 12 A
Vital Bus Retransfer Modifications Change (NRC Amendment #143, dated February 28, 1991)
- Schedule 12 A
Spent Fuel Pool Cooling Pump Change Modifications (NRC Amendment #132 dated July 16, 1990) **
The Vital Bus Retransfer Modifications have been moved to Schedule A from Schedule B with the issuance of NRC Amednment 143.
Amendment 143, dated February 28, 1991, made these modifications a License Condition.
The Spent Fuel Pool Cooling Pump Modifications have been moved to Schedule A from Schedule B with the issuance of NRC Amednment 132.
Amendment 132, dated July 16, 1990, made these modifications a License Condition.
Based on the above, there was no need to run the Westinghouse Analytical Ranking Program (WARP) to rank the safety significance of each modification.
The rankings are only used to determine the priority of scheduling work that could not be completed in the next refueling outage.
Expected Percentages Allocation Of Resources On Regulatory And Betterment Projects For The Next Refueling/Modification Outage Approximately 99% of the resource allocation of the next (Cycle 12) refueling outage is on regulatory projects.
