MONTHLY OPERATING EXPERIENCES -- MARCH, 1981 HIGHLIGHTS:

The Unit operated at 100% power until 2200 on March 13, 1981 when power reduction was started to go to Cold Shutdown for Refueling, Maintenance, and Modifications.

The Unit had been on line for 88 days, 21 hours2.430556e-4 days 0.00583 hours 3.472222e-5 weeks 7.9905e-6 months and 35 minutes.

The Unit Outage is scheduled for a duration of 55 days.

Total electrical generation for the month was 343,400 mwh.

SUMMARY

03/01/81 The East ESW Pump was inoperable for a 0.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months period due to a Strain-er Gate not being aligned to the same strainer basket. This occurred during the Automatic Cleaning Sequence.

03/04/81 The High Demand Fire Pump was inoperable for a 7.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months period for lubrication.

03/11/81 Radiation Monitor (Air Ejectors) was inoperable for a 7.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months period for Calibration.

03/13/81 At 2200, the Unit was released for shutdown.

03/14/81 At 0510, the Unit entered Mode 4 (Hot Shutdown).

03/15/81 At 1240, the Unit entered Mode 5 (Cold Shutdown). At 2227, the "CD" Diesel became inoperable due to a broken line on the starting Air Check Valve on the rear bank #4 cylinder. This diesel returned to operable at 1245 on 04/07/81 after extensive repairs by the Maintenance Depart-ment.

03/25/81 At 0100, the Unit entered Mode 6 (Refueling).

03/31/81 At 1643, a Safety Injection Actuation occurred on this Unit. The cause of the Actuation was determined to be caused by a Surveillance Test which was being performed on the Pressurizer Pressure Channels. AB Die'sel started satisfactorily and there was no injection to the R.C.

System due to Clearance on the pumps. The Test procedure has been corrected to prevent future reoccurrences.

3. A. Svensson TELEPHONE (616) 465-5901 PAGE 1 of 2 MAJOR SAFETY-RELATED MAINTENANCE MARCH, 1981 M-1 The south safety injection pump discharge drain valve, SI-109S, was found leaking by during inspection.

The 3/4" valve had a cracked seat.

The valve was removed and a new valve was welded in. All NDE requirements were met.

M-2 The suction valve for the north safety injection pump, SI-103N, had a body to bonnet leak.

Replaced the bonnet gasket.

M-3 Steam generator power operated relief valve, MRV-243, had a body to bonnet leak.

Replaced the bonnet and cage gaskets.

Had the valve tested.

M-4 Suction valve for CD diesel auxiliary jac'ket water pump, DG-150C, had a damaged stem.

The valve was replaced.

M-5 Non-essential service water containment isolation valves; WCR-909, WCR-929, WCR-931, WCR-948, WCR-951, WCR-952 and WCR-958 failed to pass the type C leak rate test.

Cleaned the valve internals, lapped the seat and replaced gaskets. Valves retested satisfactorily.

M-6 A crack was discovered in a 2 inch safety valve inlet line on the outlet of the west RHR heat exchanger. The crack was in a socket welded connection. The line was removed and a new nipple and flange for the safety valve were welded in. All necessary NDE was performed and.the welds were hydrostatic tested.

M-7 Component cooling water containment isolation check valves, CCW-243-25 and CCW-244-25, failed to pass the type C leak rate test.

Replaced the valve seats and had valves retested.

M-8 Refueling cavity drain line containment isolation valve, SF-159, failed to pass the type C leak rate test.

Replaced the valve diaphragm and had the valve retested. -

M-9 Component cooling water containment isolation valves, CCM-431 and 432, failed to pass the type C leak rate test.

Disassembled the valves, cleaned the internals and lapped the seat.

Reassembled the valves and had them retested.

l M-10 Non-essential service water containment isolation valve, NSW-419-1, failed to pass the type C leak rate test.

Disassembled valve, cleaned the internals, reassembled, and had it retested.

Replaced the valve bonnet.

M-12 Non-essential service water containment isolation check valves failed to pass the type C leak rate test.

Disassembled and cleaned valve internals, lapped seats. reassembled with new gaskets and had valves retested.

?1-13 Non-essential service water containment isolation check valve, NSW-415-1, failed to pass the type C leak rate test.

Disassembled and cleaned valve internals.

Replaced the disc, reassembled with new gaskets and had the valve retested.

C&I-l Control Rod Position Indication for Rods H6 and C7 indicated greater than demand. The voltages associated with the two RPI channels were measured and verified the rods' position. The signal conditioning modules were adjusted to provide proper indication.

C&I-2 The two east essential service water pump strainer gates had aligned to different baskets while the pump was not in service.

Agastat time relay, 62X SEST, did not operate with a time delay which resulted in

~

the strainer switching over only part of the time.

The time delay relay was replaced.

The 24-hour timer was jumpered to simulate a changeover and verify correct operation.

C&I-3 The auxiliary feedwater flow retention for motor operated auxiliary feedwater regulating valve, FM0-242, did not function.

Flow switch, FFS-245, was tested and found to be out of calibration.

FFS-245 was recalibrated and returned to service. A functional test was performed and verified correct operation.
