Enclosure INTEGRATED LIVING SCHEDULE SAN ONOFRE NUCLEAR GENERATING'STATION, UNIT 1 Fourth Edition March, 1987 Introduction Proposed License Condition 3.J, "Integrated Living Schedule of Backfits,"

requires SCE to follow the ILS Program.Plan ("Plan").

The Plan specifies that periodic schedule updates be submitted to the NRC along with specific information regarding progress in implementing NRC requirements, changes since the previous report, reasons for schedule changes and the expected percentage allocation of resources on regulatory vs. betterment projects. This document is the fourth edition of the ILS which provides that information.

Progress in Implementing NRC Requirements Since SCE's last submittal in October, 1986, SONGS 1 has not had a backfit outage. Work continues on projects scheduled for implementation during the next refueling/backfit outage scheduled for early 1988.

Of the two evaluations scheduled for completion on the Cycle X schedule, we submitted the SPDS design criteria this month. The next milestone for the Supplement 1 to NUREG-0737 projects is the submittal of the Control Room Design Review,Report. The schedule for submittal has been extended from May 1, 1987 to August 14, 1987 due to the unanticipated workload associated with evaluating the SONGS 1 control room and a secondary review of the effort to ensure compliance with NRC review requests.

This has been discussed and agreed with the NRC staff.

Changes Since Last Edition There has been only one new project added to the ILS since our last submittal. This project is the FSA update required by 10 CFR 50.71(e). In accordance with the regulation, this project is due two years after our notification by the Director of NRR of the completion of the Systematic Evaluation Program.

Expected Allocation of Resources for Upcoming Outage The refueling/backfit outage for Cycle X of plant operation is expected to have resources allocated approximately 70% to regulatory projects,and 30% to betterment projects. This allocation reflects a balancing of resource allocation following the last refueling/backfit outage which was approximately 90% regulatory work.

Updated Schedules Schedules A, B and C are attached.
