B Steam generator overfill protection system (SG0PS). See following. paragraph A
c Document Control Desk The SG0PS issue is currently under review by the NRC for the Combustion Engineering Owners Group (CE0G). As previously discussed with the NRC Project Manager, SCE is deferring iesolution of this issue pending completion of the NRC review.
Following completion of the NRC/CEOG review of this issue SGOPS will be incorporated in the llS' appropriately.
Approximately 40% of resources for the Unit 2 and the Unit 3 Cycle refueling outages will be allocated to regulatory projects.
The Westinghouse Analytical Ranking Program (WARP) was not used to rank-the relative safety significance of each Schedule A and 8 modification because their impicmentation schedules have been established in separate correspondence.
If.you have any questions on the Seventh Edition of _the San Onofre Units 2 and 3 IIS, please let me know.
Very truly yours, if 0
