CH PUMPXX Reactor power was reduced to 53% on 821129 to remve the east main feed-pump turbine from service due to ex-cessive vibration-Investigation re-vealea that the coupling sleeve on the turbine half of the coupling was cracked the length of the sleeve. A i

complete new coupling was installed.

During the return to full power on i

steam lead, down stream of the No. 3 turbine control value. To repair the l'

steam leak a power reduction to 30%

was required. The leak was repaired and the reactor power returned to 100% power on 821204.

1/10/83 Page:

1 of 2 MONTHLY OPERATING ACTIVITIES - DECEMBER 1982 Highlights:

The Unit entered the reporting period operating at 59% power. The reduction in power was due to high vibration on the East Main Feedpump. The forced outage on the Feedpump occurred on Nov. 29 and after repairs were made to the.Feedpump/ Turbine Coupling, the Feedpump was returned to service at 1730 hours0.02 days 0.481 hours 0.00286 weeks 6.58265e-4 months on Dec. 3.

Unit power was increased to 62%, and at 1830 hours0.0212 days 0.508 hours 0.00303 weeks 6.96315e-4 months on Dec. 3 a pressure test connection on the #2 Main. Steam lead to the High Pressure Main Turbine developed a leak. A power reduction to 30% was begun at 1910 hours0.0221 days 0.531 hours 0.00316 weeks 7.26755e-4 months with the reactor reaching 30% at 2140 hours0.0248 days 0.594 hours 0.00354 weeks 8.1427e-4 months . Repairs were completed to the test connection at 2315 hours0.0268 days 0.643 hours 0.00383 weeks 8.808575e-4 months on Dec. 3 and 100% power was achieved at 1423 hours0.0165 days 0.395 hours 0.00235 weeks 5.414515e-4 months on Dec. 4.

At 1850 hours0.0214 days 0.514 hours 0.00306 weeks 7.03925e-4 months on Dec. 22 power was reduced to 55% to remove the 1

~

West Main Feedpump to replace a grease seal on the Feedpump/ Turbine Coupling. The West Main Feedpump was returned to service at 0100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months on Dec. 24 and Reactor Power was increased to 70% at 0355 hours0.00411 days 0.0986 hours 5.869709e-4 weeks 1.350775e-4 months on Dec. 24. Due to system conditions, the Unit Power was held at 70% until 1245 hours0.0144 days 0.346 hours 0.00206 weeks 4.737225e-4 months on Dec. 25 at which time the Unit reached 100%

power.

At 1845 hours0.0214 days 0.513 hours 0.00305 weeks 7.020225e-4 months on Dec. 25, an oil leak developed on the West Main Feedpump Turbine and at 0200 hours0.00231 days 0.0556 hours 3.306878e-4 weeks 7.61e-5 months on Dec. 26 the Unit Power was reduced to 58%.

Following repairs to the West Main Feedpump the Unit was brought to 100% power at 1206 hours0.014 days 0.335 hours 0.00199 weeks 4.58883e-4 months on Dec. 27.

Reactor power was reduced to 95% two times during this period to test Turbine Control Valves. These are addressed in the Summary.

50 - 315 UNIT NAME D. C. Cook - Unit No.1 DATE l-13-83 COMPLETED BY B. A. Svensson TELEPHONE (616) 465-5901 PAGE 1 of 1 MAJOR SAFETY-RELATED MAINTENANCE DECEMBER,1982 M-1 MRV-231, No. 3 steam generator stop valve dump valve was leaking by. Replaced the stem, plug, pin, cage and seat. Reassembled using new gaskets and had the valve tested.

C&I-1 Gland steam exhaust vent radiation monitor, R-33, failed low.

Power supply filter capacitor and voltage regulator were re-placed to restore operability to channel R-33.

0 C&I-2 Reactor coolant loop 3 AT indicator TI-431A was reading 7 to 100F above the other 3 loops. The loop 3 " cold leg" resistance temperature detector had failed. The spare cold leg RTD for this loop was connected in-circuit. Both hot and cold leg resistance-to-voltage converter modules were recali-brated to correct the loop 3 AT indication.

C&I-3 Upper containment area radiation monitor, VRS-1201, exhibited high readings up to 1R/ hour, while other redundant monitors were trending normally. A defective Geiger-Mueller radiation detector tube, V202, was replaced. Calibration of the system was completed and the channel was verified operable.

C&I-4 Steam jet air ejector flow meter, SFR-401, was reading about two times the actual flow rate. The transmitter, square-root extractor and recorder were recalibrated.
