10NTHLY OPERATING ACTIVITIES - FEBRUARY 1983 Highlights:

i The Unit remained at 100% power during this reporting period except for those periods of time when the Main Turbine Control Valves were tested and for a short duration when a Reacto, Power reduction to 56% was started at 1930 on Feb. 4 to repair a leaking Condenser tube in the West Main Feedpump Condenser. The Reactor Power was returned to 100% at 2310 on Feb. 5.

These are addressed in the Summary.

The gross electrical generation for the month was 709,700 MWH.

Replaced the valve stem, seat, cage, plug and gasket seat and repacked the valve. Had the valve tested.

M-2 No.1 boric acid transfer pump mechanical seal failed.

In-spection revealed a pump bearing failure also.

Replaced the pump and had the new pump tested.

H-3 The East ESW strainer would not shift. Discovered that the backwash outlet valves, WRV-761 and 771 were leaking by.

Re-placed the seat rings and drive shaft bushings in both valves.

Cleaned both valves and had them tested.

M-4 CS-416, the No.1 boric acid transfer pump isolation valve to the boric acid filter was leaking by.

Replaced the diaphragm valve bonnet and diaphragm.

C&I-l Level and flow transmitters manufactured by ITT - Barton Company were modified to include soldered connections to strain gauges, per Barton Company instructions. Model 764, serial numbers 439, 376 and 1023 were so modified.
