MONTEY OPERATING REPORT OPERATING

SUMMARY

- FEBRUARY 1981 UNIT II The Unit was operating at full power at the start of this reporting period. Condenser tube leaks forced a power reduction on 2-3-81.

Full Power Operation w : achieved on 2-7-81 following temporary repairs made to the coudenser. The Unit experienced a trip from approximately 100% full power on 2-17-81 due to a failed Reed Switch Position Transmitter (RSPT) power supply. The Monthly Core Protection Calculator (CPC) Surveillance Test was in pro-gress when the Unit trip occurred. Investigation revealed the trip occurred when the RSPT power supplies were tested per the surveillance procedure. The CPC Monthly Surveillance Procedure has been changed to delete testing the power supplies during the Monthly CPC Testing and test all RSPT power supplies during the annual surveillance tests while the Unit is shut down. A return to Full Power Operation was accomplished on 2-18-81.

Full Power Operation continued for the remainder of the month.
