Subject:

Docket Nos. 50-361/50-362 Monthly Operating Reports for September 1985 San Onofre Nuclear Generating Station, Units 2 and 3 Enclosed are the Monthly Operating Reports as required by Section 6.9.1.10 of Appendix A, Technical Specifications to Facility Operating Licenses NPF-10 and NPF-15 for San Onofre Nuclear Generating Station, Units 2 and 3, respectively.

Revised August 1985 Operating Status sheets for Units 2 and 3 are included.

The revisions were necessitated by the discovery of a computer error and clerical error in reporting the generator on line hours for Unit 2, and the net electrical energy generated for Unit 3.

The af fected portions of this report have been annotated with an asterisk.

Please contact us if we can be of further assistance.
