Subject:
Docket Nos. 50-361'and 50-362 Monthly Operating Reports for January 1996 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 Edison 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 90 days from the time the changes are effective.
This letter transmits the January 1996 Monthly Operating Ry orts for Units 2 and 3.
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.
If you require any additional information, please let me know.
