O(J Cause h, Corlcctivc Actioo to Prcvcnt Rceuffcnec The Unit entered the reporting period operating at 50K power.

Reactor power was increased to 90%

790102 and held at this power level due to one circulating water pump being out of service.

Reactor power was at 1005 790112.

The Unit operated for the remainder of the month with no significant power reductions.

Lease (616) 465-5901 February 8, 1979 OPERATING EXPERIENCE -- JANUARY 1979 Hi hli hts This Unit entered the reporting period operating at 505 Power.

Loading was being held at 50'A Power (525 NWe) due to high inven-tory of waste gas in the plant.

Weather instrumentation was frozen at this time not allowing any release of waste gas.

Loading was increased to 905 January 2,

1979 and held and main-tained between this and 1005 power the rest of the reporting period.

Summar 01/02/79 Waste Gas Inventory was rearranged and the weather instrumentation freed up allowing the release of two gas decay tanks.

The Unit was loaded to 90K power (980 NWe) by 2020 hours0.0234 days 0.561 hours 0.00334 weeks 7.6861e-4 months .

Loading was held at this point due to approachinq maximum temperature rise across the Condenser;wh>le only having two Circulating Water Pumps.

01/22/?9--

The West Component Cooling Water Pump had difficulty meeting the requirements for minimum discharge pres-sure.

The suction strainer was checked and found to contain resin beads and some pieces of rubber.

The strainer was removed and the pump retested satisfac-torilyy.

01/26/79 Power was reduced to 85K (890 MWe) for testing of Turbine valves.

Time span from unloading back to 1004 power was two hours.

The "AB" Emergency Diesel Generator was inoperable

~for a 7.75 hour8.680556e-4 days 0.0208 hours 1.240079e-4 weeks 2.85375e-5 months period for changing of lubricating oil in the Governor and the Turbo Charger.

Replacement, of the North Condensate Booster Pump motor was started and was completed January 28, 1979.

01/29/79 -- The North half of "A" Condenser was out of service for 10.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months for location and plugging of leaking tubes.

Annual inspection and overhaul of the plant air compressor was started and this job was completed

Thursday, February 1,

1979.

01/30/79 The East Centrifugal Charging Pump was inoperable for a 21,.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months period for replacement of a mecha-nical seal and cleaning of the lube oil filter.

All motor operated Auxiliary Feedwater Valves were removed from

service, one at a time, for inspection of electrical connections and checking of tightness of terminals.

One of the Pressurizer Safety Valves is leaking through at the rate of 2 GPM.

The water in the Pressurizer Relief Tank is being kept cool by the feed and bleed method.

This is adding to evaporator requirements.

No.

4 steam generator stop valve dump valve, MRV-242 was leaking by.

Dis-assembled valve, cleaned internals, replaced seat and gaskets.

Timed retest was satisfactory.

The scan sequencer of the axial power distribution monitoring system failed.

The sequencer 1 printed circuit board was repaired.

An op-erational test was performed and verified the systems operability.

The rod position indication for control rod F-6 was out of specifications.

The position signal for rod F-6 was measured and recorded as 2.885 vdc.

The secondary coil voltage was verified and the calibration of the signal conditioning module was performed.

The axial power distribution monitoring system failed to perform the eight hour scan.

The time sequencer digital display also failed.

The timer sequencer printed circuit board required replacement.

The panel. rod position indication for control rod F-6 was out of speci-fications.

The LVDT secondary coil voltage was measured and verified correct.

The signal conditioning modules output signal was recorded as 2.885 vdc.
