1988 818-302-1401 U. S. Nuclear Regulatory Commission Attention:

Document Control Desk Washington, D.C. 20555 Gentlemen:

Subject:

Docket No. 50-206 Amendment Application No. 158 San Onofre Nuclear Generating Station Unit 1 Enclosed is Amendment Application No. 158 to the Provisional Operating License DPR-13. Amendment Application No. 158 consists of Proposed Change No. 184, which is a request to revise Appendix A, Technical Specifications, of Provisional Operating License DPR-13.

Proposed Change No. 184 is a request to revise Appendix A Technical Specifications to incorporate Limiting Conditions for Operation and Surveillance requirements for the revised Auxiliary Feedwater System (AFWS).

To eliminate single failure susceptibilities in the AFWS, a third pump will be added. The revised system configuration will consist of two trains, with the new pump on one train and the existing two pumps on the other train. The new system will function with a lead train providing the necessary decay heat removal capability, and the second train remaining in standby to provide flow should a malfunction occur in the lead train. To preclude exceeding water hammer limits, train interlocks and mechanical flow restrictors will be incorporated into the new design.

It is noted that through the review of the Technical Specifications associated with plant modifications to implement the revised AFW system, a reportable situation was identified regarding the existing Technical Specification minimum water volume requirements for the AFW storage tank.

As a result, this proposed change includes a revision to the minimum water volume requirement to compensate for this situation. This situation has been the subject of discussions with the NRC Staff and additional information will be provided in a forthcoming Licensee Event Report.

Pursuant to 10 CFR 170.12, the review of Proposed Change No. 184 contained in Amendment Application No. 158 has been determined to require a fee of

$150.00. Accordingly, SCE's check in the amount of $150.00 is enclosed.
