DOCKET N0. 50 - 315 UNIT NAME D. C. Cook - Unit No.1 DATE 12-14-82 COMPLETED BY B. A. Svensson TELEPHONE (616) 465-5901 PAGE 1 of 1 MAJOR SAFETY-RELATED MAINTENANCE NOV EMBER,1982 M-1 The North boric acid tank recirc valve, QRV-410, appeared plugged.

Disassembled and cleaned valve internals. Reassembled using new gaskets and bonnet studs. Had the valve tested.

M-2 The North control room air conditioner chiller package would not turn on. The molded case circuit breaker would not reset. Re-placed the breaker and had the package started and it ran without probl ems .

M-3 An electrical ground developed on one circuit of pressurizer backup heaters on bus llPHA. The feed wires to one of the backup circuit breakers were found burned and grounded to the tub. Replaced the wires and the circuit breaker and had the circuit functionally tested.

M-4 The isolation valve for the alternate supply to the turbine driven auxiliary feedpump from ESW, WM0-753, would not open. The motor was damaged due to installation of a recent modification which reversed the motor rotation. Replaced the motor and had phase rotation problem corrected. Had the valve tested.

C&I-l Containment non-essential service water isolation valve, WCR-932, failed closed and could not be opened from the control room. Water was found to have entered the actuating asco valve coil, shorting it electrically. The terminal box was dried and the coil was re-placed. Correct valve operation was verified after repair.

C&I-2 Containment non-essential service water isolation valve, WCR-914, lower containment ventilation Unit No. 4, failed closed and caused a "CD battery ground" annunciation. The terminal box was dried and asco solenoid was replaced. Correct valve operation was verified after repair.

C&I-3 Subcooling margin monitor pressure readings were abnormally high with temperature readings below normal . The instrument temperature module was in error and was replaced and calibrated. Pressure transmitter, NPS-122, was recalibrated to correct the pressure input. The subcooling margin monitor response was verified with the Westinghouse P-250 computer and also with the Technical Support Center computer. All are in coincidence at Tsat. margin of 480F at 100% power.

Docket No.: 50-315 Unit Name: D. C. Cook Unit 1 Completed By: C. E. Murphy Telephone: (616) 465-5901 Date: 12-9-82 Page: 1 of 2 MONTHLY OPERATING ACTIVITIES - NOVEMBER 1982 Highlights:

The Unit entered the reporting period operating at 100% power.

Reactor power was reduced to s95% four times during this reporting period for Turbine Control Valve testing. These will be addressed in the summary.

On November 28, a vibration problem developed on the East Main Feedpump which resulted in the Unit load being reduced in a normal 6% per hour rate. At 0536 hours0.0062 days 0.149 hours 8.862434e-4 weeks 2.03948e-4 months on November 29, the Unit load decrease was stopped at the 53% power level and the feedpump was removed from service for repairs.

The Unit load remained at 53% power for the remainder of this reporting period. The feedpump vibration problem proved to be a turbine to pump coupling problem and Maintenance is proceeding with repairs.

The gross electrical generation for the month was 747,420 MWH.
