ENCLOSURE INTEGRATED IMPLEMENTATION SCHEDULE SAN ONOFRE NUCLEAR GENERATING STATION, UNIT 1 NINTH EDITION JUNE 1990 Introduction License Condition 3.J, "Integrated Implementation Schedule" (IIS), requires 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 and also: 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 ninth edition of the IIS, provides the required status update for the period November 1989 through May 1990.
The eighth edition of the IIS was provided to the NRC by letter, F.
R. Nandy to NRC Document Control Desk, dated November 16, 1989.
The current Schedules A, B, and C are attached as Attachments 1, 2 and 3, respectively.
Progress In Implementing NRC Requirements Since the last submittal (IIS Eighth Edition) in November 1989, Unit 1 did not have a refueling or modification outage; one 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> maintenance outage occurred to repair backup nitrogen regulators (LER No.89-028).
In the Eighth Edition of the IIS letter, SCE reported that the Automatic Vent System (AVS) for the Boric Acid System was substantially completed and would receive final testing by November 30, 1989.
As reported in the letter, F. R. Nandy (SCE) to the NRC, dated March 5, 1990, the final testing which was completed on November 30, revealed that additional design work was required. Consequently, the AVS modifications will be completed in the Cycle 11 refueling outage.

Changes Since The Last Report And The Reasons For Schedule Changes Associated With Schedules A and B On January 2, 1990, the NRC issued "Order Confirming Licensee Commitments on Full-Term Operating License Open Items -
San Onofre Nuclear Generating Station, Unit 1 (TAC No. 11232)".
This Order resulted in several Cycle 11 and Cycle 12 modifications being moved from Schedule B to Schedule A.
Also the Order added two new modifications to Schedule A for Cycle 11.
The changes due to the NRC Order are as follows:
NRC ORDER -
UPGRADED CYCLE 11 SCHEDULE B TO SCHEDULE A MODIFICATIONS CCW Permanent Fix Charging Pump Motor Rewind Design Basis Precipitation Modifications (Rooftop Drainage Modifications -
Scuppers) 480V Overload Modifications EQ of Hot Leg Recirculation System Mid-loop Water Level Indication (RWLI)
NRC ORDER -
UPGRADED CYCLE 12 SCHEDULE B TO SCHEDULE A MODIFICATIONS Safety Injection Recirculation System Modifications Safety Injection System Improvements NUREG-0612 Turbine Deck Steel Plating Safety Parameter Display System Control Room Design Review Modifications (All Groups)
Upgrade Core Exit Thermocouples (To be implemented with Schedule A RVLIS)
Control Room Habitability CVCS Valves MOV-LCV-1100 B, C, and D Addition of Synchrocheck Relays to Emergency Diesel Generators Undervoltage Relays for Protection from Degraded Grid Voltage (SEP VIII-1.A)
Waste Gas Decay Tank Monitoring Instrumentation Inservice Testing Modifications NRC ORDER -
NEW CYCLE 12 SCHEDULE A MODIFICATIONS Steam Generator Overfill Single Failure Analysis Separation & RG 1.97, including non-single failure 2
SCE has added five new modifications to Schedule B as the result of plant operating events which were the subject of Licensee Event Reports (LER).
These modifications are as follows:
NEW CYCLE 11 SCHEDULE B MODIFICATIONS -
LERs CV-517 and CV-518 actuator upgrades committed to in LER No. 90-05 HV-851A and HV-851B backup nitrogen upgrade committed to in LER No. 89-28 Auxiliary Feedwater venturi modification committed to in LER No. 89-31 Spent Fuel Pool cooling pump addition (short term) committed to in LER No. 90-10 NEW CYCLE 12 SCHEDULE B MODIFICATIONS -
LERs Spent Fuel Pool Cooling pump modification (long term exact modifications are yet to be determined) committed to in LER No. 90-10 and SCE Amendment Application No. 183, dated May 16, 1990 In addition, two new Schedule B modifications have been scheduled for Cycle 11: upgrades to valves SV2900 and SV3900 which resulted from the Safety Injection System review which was conducted as described in the letter, M. 0. Medford to NRC, dated July 25, 1988; and replacement of the Utility Bus panel, which was identified during assessments of NRC Bulletin 88-10, initiated as a result of the letter, M. 0. Medford to the NRC, dated March 30, 1989.
Also, one new Schedule B modification has been scheduled for Cycle 12: the Emergency Response Data System committed to in the letter, Mr. Harold B. Ray to the NRC, "Response to Generic Letter 89-15", dated December 26, 1989.
All the modifications which were added to Schedules A and B will be completed in the respective Cycle 11 or Cycle 12 Refueling outage.
It is not possible to move any of the Cycle 12 projects to Cycle 11, since the outage is about to begin. Since all remaining projects are scheduled for Cycle 12, 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 (Cycle 11) refueling outage.

Expected Percentage Allocation Of Resources On Requlatory And Betterment Projects For The Next Refueling/Modification outage All (100%) of the resource allocation of the next refueling is on regulatory projects; there will be no resource allocation on betterment projects.
