Subject:

Docket Nos. 50-361 and 50-362 Monthly Operating Reports for-September 1992 San Onofre Nuclear Generating Station, Units 2 and 3 Technical Specification 6.9.1.10 to Facility Operating Licenses NPf-10 and NPF-15 for the San Onofre Nuclear Generating Station, Units 2 and 3, respectively, requires SCE provide a Monthly Operating Report for each Unit, which includes: routine operating statistics and shutdown experience; all challenges to safety valves; any changes to the Offsite Dose Calculation Manual (0DCM); and any major changes to the radioactive waste treatment system. All covered activities are reported monthly, except for ODCM changes,' which are reported within 90 days from the time the changes were made effective.

This letter transmits the September 1992 Monthly-0perating Reports for Units 2-and 3, respectively. There were no challenges to safety valve , no changes to the ODCM, and no major changes to the Units 2 and 3 radioactive waste treatment systems during the reporting period.

If you require any additional information, please let-me know.
