The Unit entered this reporting period in Mode One and at 100% Reactor power. The Unit operated at 100% Reactor power the entire period except for a reduction of power to 90% for about three hours each Friday of the period to do routine tests of the Turbine Control Valves.

Summary:

9-02-81 The "B" string of H.P. heaters were removed from service to make repairs.

This caused +15-20 MWE loss of power generation.

9-27-81 The "B" string of H.P. heaters were returned to service.

9-21-81 "A" North Condenser was removed from service for eight hours to check for tube leaks.

MAJOR SAFETY-RELATED MAINTENANCE SEPTEMBER, 1981 M-1 The boron injection tank train "B" heaters were discovered to have a ground.

One heater and a cable were burned up. The heater and cable were replaced and the system was functionally tested.

M-2 Primary water isolation valve to No. 2 boric. acid transfer pump, CS-414-2 was leaking.

Replaced the valve diaphragm.

M-3 The reciprocating charging pump had a stuffing box leak.

Replaced the stuffing box, piston packing, adaptors, throat bushing and spring.

Had pump tested.

C&I-l Radiation Monitoring System Channel R-25, ' unit vent air particulate mon-itor filter paper drive mechanism would not advance. The drive motor was removed and replaced with a spare motor. The drive mechanism clutch as-sembly was repaired. The channel was returned to normal service.

C&I-2 Radiation Monitoring System Channel R-15, steam jet air ejector monitor count rate increased without an increase in sample activity.

The chan-nel's drawer assembly was tested and determined to be within specifica-tions.

The monitor's detector tube was replaced with a spare and the

~.

channel calibrated.

During the performance of surveillance test procedure 1 THP 4030 STP.045, C&I-3 Reactor Logic Train "A" and B", test position 18 of the test switch of the solid state protection system failed to test correctly.

Universal logic card A210 failed to function as required.

The card was replaced and correct operation was verified.
