Subject:

Docket Nos. 50-361 and 50-362 l Monthly Operating Reports for August 1995 San Onofre Nuclear Generating Station, Units 2 and 3 l

Technical Specification 6.9.1.10 of Facility Operating Licenses NPF-10 and NPF-15 for the San Onofre Nuclear Generating Station, Ur.its 2 and 3, i i respectively, requires Edison to provide a Monthly Operating Report for l each Unit, which includes: routine operating statistics and shutdown l experience; all challenges to safety valves; any changes to the Offsite Dose Calculation Manual-(ODCM); and any major changes to the radioactive waste treatment system. All covered activities are-reported monthly, except for CDCM changes, which are reported within 90 days from the time the changes are effective, l

i This letter transmits the August 1995 Monthly Operating Reports for Units 2 and 3, respectively. There were no challenges to safety valves, no major changes to the Units 2 and 3 radioactive waste treatment systems, and no changes to the ODCM during the reporting period, t

If you require any a witional information, please let me know.

i Sincerely, l W i Enclosures cc: .L. J. Callan, Regional Administrator, NRC Region IV J. E. Dyer, Director, Division of Reactor Projects, NRC Region IV K. E.
