Total electrical generation for the month was 815,330 mwh.

~Sunna r 5/1/80 The Turbine Driven Auxiliary Feedwater Pump was in-operable for a 5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> period for, testing of trip and throttle valve.

5/3/80 Containment Radiation Monitor R-11 5 R-12 were inoper-able foi a 17 hour1.967593e-4 days <br />0.00472 hours <br />2.810847e-5 weeks <br />6.4685e-6 months <br /> period for replacement of the sample pump.

Reactor power was lowered to 96/ to return the Reheater Coils to service following an automatic isolation of the Reheater Coils. After several unsuccessful attempts to return the coils to service the Unit was reloaded to 100Ã power and operated non-reheat. Total time below 100Ã power was 13.5 hours.

5/5/80 Reactor power was again reduced to 96K for a 5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> period to attempt to return the Reheater Coils to service.

5/6/80 Through testing it was determined that there was a tube .

leak in the north set of Reheater Coils. Unit power was reduced to 965 and the south set of Reheater Coils were pl,aced .in service. Total time below 100/ power was 8.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />.

5/9/80 The south set of Reheater Coils were isolated due to a high level in one of the Coil Drain Tanks. Power was reduced to 97/ and three unsuccessful attempts were made to return these coils to service. Further testing indicated the coils to have failed tubes. Reactor power was returned to, 1005. Total time below 100K was 11.25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br />. Unit operation continues in the non-reheat mode.

5/10/80 Reactor power increased to 101/ when a non-borated demineralizer was mistakenly valved in to the Reactor Coolant System. Rapid response by the Control Room Operators using control rods and boration reduced the

5/15/80-- Containment Radiation Monitor R-11 was inoperable for a 1.25 hour2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> period due to the filter failing to move.

5/16/80 -- The sample pump for Containment Radiation Monitors R-11 and R-12 failed at 0750. Repairs were made and the mon-itors were again operable at 0617, 5/17/80.

Reactor power was reduced to 60% over a 1.25 hour2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> ramp starting at 1330 to remove the East Main Feed Pump from service so the Condenser for this feed pump could be checked for a tube leak. One leak was located and plugged.

The pump was returned to service and the unit loaded to 100Ã power over a 4 ho'ur ramp starting at 2100 the same day..

5/20/80-- ESF Vent Fan 2-HV-AS-2 was inoperable for a 11.75 hour8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> period for replacement of the ruffing filter.

The Turbine Driven Auxiliary Feedwater Pump tripped.

This was while the pump was in it's normal standby (not running) condition. The turbine was reset, test run, and declared operable.

5/27/80-- A review of ISI test data sheets indicated that the Turbine Driven Auxiliary Feed Pump had not met the minimum required discharge pressure. Since the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> time interval for an "inoperable pump" specified in the Action statement had been exceeded, the pump had to be proven operable or the unit placed in hot standby within one hour. Unloading of the unit was initiated while retesting of the pump was under way.

Unit unloading was stopped at 97'/ when the pump was proven operable. The unit was reloaded to 1005 power.

Total time below 100% power was 1.25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br />.

5/28/80-- The Steam Jet Air Ejector Radiation Monitor R-15 was removed from service at 1004 for moisture proofing of the detector tube. 'This detector was returned to service at 0917, 5/29/80.

Cook - Unit No. 2 DATE 6-11-80 COMPLETED BY 'BBB. svensson TELEPHONE 616 465-5901 PAGE 1 of 2 MAJOR SAFETY-RELATED MAINTENANCE MAY, 1980 Low flow was detected from the sample pump for R-25, containment air particulate detector. Replaced the pump and verified operability.

The CCW sparge tank east level recorder isolation valve, CLR-410V2 was

'leaking.'. Replaced valve and tubing.'o.

M-3 3 steam generator power relief valve, MRV-233 was leaking by. All gaskets were replaced; disc,, pilot disc and pilot seats were machined.

The valve was leak tested and operability verified.

CSI-1 The pressurizer level control system would not maintain the set point level during automatic operation. The reset action of level controller LC-459 was removed and flow controller FC-121 gain was reduced. The control system now responds and maintains pressurizer level at the pro-grammed set point.

CRI-2 Steam generator level protection set III, steam generator No. 3 level low-low and high level bistable LB-538AlB required replacement due to a drift problem in the high alarm set point. A spare bistable was installed and surveillance test 2 THP 4030 STP 117 was performed

~ to verify the channel's operability.

CSI-3 Ice condenser temperature recorder SG-017 indicated off scale at the low end of travel. The servo motor, point selector switch and pen drive amplifier card were replaced. ,The recorder was calibrated per 12 THP 6030 IMP.079 and returned to service.

C& I-4 The comparator and rate drawer channels for the nuclear instrumentation system displayed a deviation alarm. The alarm was present with the deviation between .channels less than the required set point. The bistable card for channel deviation alarm actuation was replaced with a spare card and the calibration of the bistable was performed.

CSI-5 Radiation Monitoring System Channel Rll, containment air particulate monitor, air pump tripped without producing an alarm in the control room. The alarm bulb had been replaced with a neon type which was incorrect. A filament type bulb was installed and operated properly.

The air pump was tripping on low air flow. The air flow indication rotometer required replacement. The alarm unit was calibrated for correct set points and the air flow rate was adjusted for 10 cfm flow.

DOCKET NO. 50 316 UNIT NAME D. C. Cook - Unit No. 2 DATE 6-11-80 COMPLETED BY B. A. Svensson TELEPHONE 616 465-5901 PAGE 2of2 MAJOR SAFETY-RELATED MAINTENANCE MAY, 1980 The analog rod position indication meter for control rod M-2 was in-dicating full scale. The panel meter was removed and a spare meter was installed. Correct rod position indication returned.

The pressurizer pressure control hand/automatic station was not oper-ating properly in either position. An out-of-balance condition in the pressurizer pressure master control module PC-455A was discovered.

This module tracks the hand/auto station when in the "manual" position, so that change-over to "auto" will not cause a step-change to the spray valve and other controllers following PC-455A. The module was balanced and retracked, and a set point dial calibration was performed. Pressure control then was satisfactory.
