2/16/80 -- Power was reduced to 90% for testing of turbine control valves.

Total time below 100% power was 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months .

Power was reduced to 65% of a 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ramp starting at 1040 hours0.012 days 0.289 hours 0.00172 weeks 3.9572e-4 months to remove the West Main Feed Pump from service.

This pump had been showing minor vibration problems. The vibration pattern showed an oscillation between 1 and 2 rails over an 8-minute time span. A balance weight was placed on the pump and it was returned to service at 0145 2-18-80.

The Unit was~ returned to 100% power by 1045 the same day.

The balance weight did not help the oscillating. This vibration pattern went away 2-29-80.

At this time there is no explanation as to what caused it.

2/17/80 -- The filter paper drive on stack particulite Radiation Monitor R-25 failed at 1630 hours0.0189 days 0.453 hours 0.0027 weeks 6.20215e-4 months .

Repairs were made and this was again retu ned to service at 1350 hours0.0156 days 0.375 hours 0.00223 weeks 5.13675e-4 months 2-24-80.

Replaced all valve gaskets and had valve retested.

M-2 The HEPA filter for ESF ventilation system fan HV-AES-1, has a high DP.

Replaced HEPA filter and had unit tested.

C&I-l ZRV-014, the fire protection water supply to ventilation Unit 1-AES-1,.

would not open manually when the actuation button was depressed.

Time delay relay 62-ESS-1 was found energized, preventing the sole-noid valve from energizing and opening ZRV-D14.

A 50 microfarad capacitor utilized as a filter in the power supply circuit failed.

The capacitor was replaced with a spare and an operational test of the control circuit was performed.

C&I-2 ZRV-023, the fire protection water supply to the control room pressurizer / cleanup filter system (1-HV-ACRF), would nct open manu-ally when the actuation button was depressed.

Time delay relay 62 CRPF was energized which prevented the solenoid valve from ener-gizing.

The circuit board was replaced and an operability test was performed to verify correct operation.

C&I-3 C-4, overpower delta T block rod withdrawal and turbine runoack, was received at 99% reactor power operation.

...a resistance to voltage converter output voltages was measurt J for comparisons on all four protection sets.

Loop No. 4 indicated the highest AT% power value, and was producing the annunciator actuation.

The hot leg RTD terminations in the rack were found loose.

The ter-minations were tightened and the AT% power signal decreased 7% of power Loop 4 was returned to normal operation.
