1 of 1 MONTHLY OPERATING ACTIVITIES - JULY, 1982 Highlights:
The Unit operated at 100% power for the entire reporting period except as detailed in the sumary.
The electrical generation for the month was 801,930 MWH.
Sumary:
7-02-82 The "AB" Diesel Generator was inoperable for a 2.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months period for the ICS Calibration.
7-09-82 The flow path for the Boric Acid Storage Tank via the transfer pumps and charging pumps to the Reactor Coolant System was made inoperable for a 1.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months period to repair a body to bonnet leak on a manual isolation valve for Emergency Boration.
7-14-82 The North Rod Drive M.G. Set was out of sert ice for a 7 hour8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months period to replace a defective trip relay in the output breaker.
7-15-82 The Turbine Driven Auxiliary Feedpump was inoperable for a 1.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months period to replace a coil in the Trip and Throttle Valve.
7-24-82 The Loop 3 over temperature AT instrument was inoperable for 6.25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months to replace the set-point module.
7-30-82 At 0000 hours0 days 0 hours 0 weeks 0 months a power reduction to 95% was started to perform a Moderator Temperature Coefficient Test. The test was completed at 1548 hours0.0179 days 0.43 hours 0.00256 weeks 5.89014e-4 months and the power level was returned to 100% at 0020 on July 31.
7-31-82 At 0145 the primary to secondary leak rate was calculated to be 0.17 gpm and at 0315 a controlled unit shutdown was started, with the Reactor being made sub-cirtical at 0211 on August 1,1982. The Unit is presently cooled down to Mode 5.
The RCS is degassed, depressurized, and at h loop being cooled by the RHP, System.
Preparations are being made to inspect #21 Steam Generator, for locating and plugging of any tubes that indicate leakage.

Svensson TELEPHGNE (616) 465-5901 PAGE 1 of 1 MAJOR SAFETY-RELATED MAINTENANCE JULY,1982 M-1 No. 2 steam generator power-operated relief valve, MRV-223, had a body-to-bonnet leak. Replaced the bonnet gasket and seal ring and had the valve retested.
M-2 Boric acid system isolatien valve, CS-485, was leaking. Replaced the valve diaphragm.
M-3 The discharge check valve for 2CD2 diesel fuel oil transfer pump, DF-ll5C, leaked by. Cleaned the discharge check valve for both 2002 and 2C01 fuel oil transfer pumps.
C&I-l Reactor Coolant Pump No. 3 motor air cooler non-essential service water inlet flowmeter, WFA-953, was intermittently failing high.
This caused flow mismatch alarms to be received. The problem was traced to a defective circuit board in WFA-953. After replacement of the circuit board, the transmitter was recalibrated.
C&I-2 ABT-5 Feeder to CRP-3 failed to transfer automatically when lighting transformer 2 "N" was taken out of service for breaker cleaning. The lockout relay was adjusted and the ABT was cycled several times to verify correct operation.
C&I-3 Steam generator No. 21 blowdown radiation monitor, R-19, had no flow indication. Replacement of the flow regulator diaphragm restored the flow to normal. The sight glass was also cleaned.
C&I-4 Turbine-driven auxiliary feedwater pump control bus, distribution cabinet 2 DCN circuit 6, was inoperable. The trip and throttle valve coil was found to have shorted. The defective coil was replaced and the control bus was returned to service with no further incident.
