Subject:

Docket Nos.-50-361 and 50-362 Monthly Operating-Reports for March 1994 San Onofre Nuclear Generating Station, Units 2 and 3 Technical Specification 6.9.1.10 of Facility Operating Licenses NPF-10 and NPF-15 for.the San Onofre Nuclear Generating Station, Units 2 and 3, respectively, requires SCE to 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 (ODCM); and any major changes to the radioactive waste treatment system. All covered activities are reported monthly, except for ODCM changes, which are reported within SK) days from the time the changes were made effective.

This letter. transmits the March 1994 Monthly operating Reports for Units 2 and 3, respectively. There were no' challenges to safety valves, 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.

Sincerely, ape &
