MONTHLY OPERATING ACTIVITIES - FEBRUARY, 1981 Highlights:

The Unit operated between 90 and 100% full power throughout the reporting period.

The pressurizer PORV's 151 and 152 have been isolated this entire period due to valves leaking through.

Total electrical generation for the month was 727,710 mw.

50 - 315 UNIT NAME D. C. Cook - Unit No. 1 DATE 3-11-81 COMPLETED BY B. A. Svensson TELEPHONE (616) 465-5901 PAGE 1 of 1 MAJOR SAFETY-RELATED MAINTENANCE FEBRUARY,1981 M-1 The emergency leak-off line check valve for the west motor driven auxiliary feedpump, FW-160, leaked by. This resulted in pressurizing the suction piping when the east pump was tested. Cleaned valve in-ternals and had systems tested to verify proper performance.,

M-2 Auto vent to ESW aftercooler for CD diesel was leaking by.

Replaced ball float valve and gasket.

M-3 The reciprocating charging pump had stuffing box leaks.

Replaced all pump suction and discharge valves.

Repacked all five cylinders and installed new throat bushings. Also, replaced the plunger and packing parts in No. 1 cylinder.

The pump was tested to verify sat-isfactory performance.

C&I-l The containment pressure recorder was reading 2.5 psig low. The re-corder was found to be 1 psig low and was recalibrated.

Pressure transmitter, PPA-312, was also low and was recalibrated to restore correct indication to the containment pressure recorder.

C&I-2 Feedwater flow to transmitter, FFC-211, No. 1 steam generator had a leak in the high pressure side threaded tap. A defective tee fitting was repitced to eliminate leakage.

C&I-3 Unit 2 shutdown bank D, rod N-ll, was indicating 240 steps on the rod position indication system and 228 on the demand indication. After verifying the LVD transformer secondary voltages for all rods in SD bank D, the signal conditioning modules for rods N-ll and B-6 were adjusted to track the indications for these rods.

C&I-4 CFA-411, component cooling water flow to the east centrifugal charging pump would not indicate a flow change when the valve was adjusted.

The instrument lines were plugged and were blown down.

The instrument calibration was verified.and returned to normal operation.

C&I-5 Dual bistable,1 TB-412 D/G, A T/TAVG Protection Set 1 was found to be out of specification during performance of the surveillance test procedure.

The bistable was replaced and the new bistable was re-calibrated in accordance with procedure 1 THP 6030 IMP.094.

C&I-6 Critical Control Room power switched over to its emergency power supply.

Water leaking from an overhead ventilator on to the power supply circuit board had caused a fuse to blow. Other components on the board were checked and were found to be intact.

The power supply inverter was protected from water and returned to service.
