1 of 1 MONTHLY OPERATING ACTIVITIES - AUGUST, 1981 Highlights:

The Unit entered this period in Mode Three following refueling.

The reactor was made critical at 0854 hours0.00988 days 0.237 hours 0.00141 weeks 3.24947e-4 months , August 1,1981. This was the beginning of the Physics Testing.

Unit was paralleled at 0614 hour0.00711 days 0.171 hours 0.00102 weeks 2.33627e-4 months , August 4,1981. At 1847 hours0.0214 days 0.513 hours 0.00305 weeks 7.027835e-4 months , August 4,1981, Unit removed from service for overspeed testing.

2028 hours0.0235 days 0.563 hours 0.00335 weeks 7.71654e-4 months , August 4,1981 the Unit was again paralleled.

At 1517 hours0.0176 days 0.421 hours 0.00251 weeks 5.772185e-4 months , August 7,1981 the Unit tripped from pressurizer high level because channel NLP-153 was inadvertantly valved out with NLP-152 in trip for calibration. The trip was from 48% power.'

The reactor was made critical the same day, paralleled at 2205 hour0.0255 days 0.613 hours 0.00365 weeks 8.390025e-4 months and power physic tests were continued.

August 14,1981 at 1800 hour0.0208 days 0.5 hours 0.00298 weeks 6.849e-4 months , a power reduction was started due to an engineering review indicating that the safety related 4 KV power busses had not been adequately supported for their seismic class.

Sixty percent power was reached at 0254 hour0.00294 days 0.0706 hours 4.199735e-4 weeks 9.6647e-5 months , August 15, 1981. At 0825 hours0.00955 days 0.229 hours 0.00136 weeks 3.139125e-4 months the seismic supports were temporarily repaired and a power increase started. Reactor power was at 100% at 1403 hours0.0162 days 0.39 hours 0.00232 weeks 5.338415e-4 months , August 17, 1981. The Unit operated at s100% power for the remainder of the month, except for a short period of time at 90% power to test turbine valves.

Replaced the No. 3 seal and the No. 1 seal insert.

M-2 A vent valve at the top of No. 3 steam generator, MS-106-3 had a packing leak.

The leak was sealed by Furmanite injection M-3 Disassembled No.1 through No. 4 steam generator stop valves, MRV-210, 220, 230 and 240 and replaced all upper and lower disc guide studs.

Reassembled valves and had the valves tested.

M-4 No. 3 steam generator stop valve dump valve, MRV-232 was leaking by.

Replaced the valve stem and plug.

Lapped the plug to the seat.

Re-packed the valve and had it tested.

M-5 The inner door of the containment personnel airlock on the 612' elevation had a broken interlock cable.

Replaced the cable and tested the door.

M-6 The tapered pin on the 1AB diesel fuel rack assembly at the bell crank shaft was worn and bent.

Replaced the tapered pin and retested engine.

C&I-l MRV-233, steam generator No. 3 power operated relief valve would open approximately 4% when the controller was in the auto mode and not re-quired.

The controller's calibration was tested and the setpoint dial was found out of specification.

The setpoint dial was adjusted to the correct value and proper operation of the controller was verified.

C&I-2 A 4% difference was indicated on the pressurizer level protection set indication in the control room. The reference leg of NLP-151, pro-tection channel No.1 was filled. The indication returned to the cor-rect value.

C&I-3 Annunciator 11 Drop 6, 'Tavg High' was received with Tavg at approxi-mately 561.5 F.

The alarm module's calibration was tested and found to be out of specification. The module was recalibrated'and returned to service.

C&I-4 IPA-131, accumulator No. 3 control room indication failed. The instru-ment loop was tested and a fuse was found blown in the loop's power supply.

The fuse was replaced. The test point voltage was measured at 1.7 volts with the normal maximum being 0.5 VDC. The problem was iden-tified as a shorted feed-through in the penetration. The circuit was changed to a different penetration and correct operation of the instru-ment loop was verified.

The temperature transmitter, 0

0 QTC-410 indicated 170 F at the transmitter and 175 F at the control room panel.

The alarm bistable's calibration was tested and the high alarm setpoint was found to be 1.875% low. The bistable was recalibrated and returned to service.

The calibration of the transmitter was tested to detenmine the reason for the difference in indications. The process temperature point on the transmitter was found binding. The transmitter was within specifications and the pointer was freed.

Control Rods' Control Bank C Low Alarm was received with the rods at 228 C&I-6 and all associated RPI Channels indicating > 228. The insertion limit computer modules were tested.

ZY-4328 high limit was found out of spec-ification. The high limit was calibrated to the correct value and the low alarm was verified to actuate at 220 steps.

C&I-7 The 50' wind recorder paper drive was not working..The defective drive motor was replaced and all drive components checked.
