Subject:

Docket Nos. 50-361 and 50-362 Monthly Operating Reports for February 1995 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,

  • respectivelyIncludes:

which requires routineEdison to provide operating a Monthly statistics Operating and shutdown Report for each experience; dnit,hallenges all c 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 90 days from the time the changes are effective.

This letter transmits the February 1995 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, .
