1 of 1 MONTHLY OPERATING ACTIVITIES - APRIL, 1982 Highlights:

The Unit entered the reporting period at 100% power. On April 17, power was decreased to 72% due to excessive number one seal leak-offs on all four Reactor Coolant Pumps.

This condition corrected itself and the Unit was back to 100% power on April 18, 1982.

On April 24, 1982, a one percent load drop was necessary due to an elevated Main Condenser AT caused by removal of a condenser half to check for leakage.

The Unit tripped on April 27, 1982 due to low vacuum on the main turbine condenser. The loss of condenser vacuum was caused by a leaking motor operated shutoff valve on the air take-off of one of the startup air ejectors. All systems worked well.

The Unit was paralleled to the grid on April 28, 1982 and reached 100% power at 0730 hour0.00845 days <br />0.203 hours <br />0.00121 weeks <br />2.77765e-4 months <br /> on April 29, 1982.

4-17-82 At 1504 hours0.0174 days <br />0.418 hours <br />0.00249 weeks <br />5.72272e-4 months <br /> power decrease was started due to excessive number one seal leakoffs on all four Reactor Coolant Pumps.

4-18-82 Power back to 100% at 0250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br />.

4-24-82 Power was dropped to 99% for 25 minutes to bring the main condenser AT back into limits following the removal of a main condenser half to check for leakage.

4-27-82 The Unit tripped from low vacuum at 1453 hours0.0168 days <br />0.404 hours <br />0.0024 weeks <br />5.528665e-4 months <br />.

4-28-82 At 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> the Reactor was made critical.

At 0641 hours0.00742 days <br />0.178 hours <br />0.00106 weeks <br />2.439005e-4 months <br /> the Unit was paralleled to the grid.

Replaced the diaphragm in sample valve, CS-428M.

M-?

The middle boric acid storage tank outlet valve, CS-408, would not close completely.

Replaced the valve bonnet and diaphragm.

M-3 The west motor-driven auxiliary feedpump emergency leak-off line check valve, FW-160, was sticking open.

Replaced the valve disc and lapped the seat.

M-4 No. 1 steam generator power-operated relief valve, MRV-213, was leaking by., Replaced stem and plug.

Reassembled with new gaskets and had valve tested.

C&I-l Containment hydrogen sample return valve, ECR-10, and lower containment volume air sample valves, ECR-13 and 23, would not cycle open/ closed.

Open-circuited solenoids were found on ASCO pilot valves to ECR-10 and

11. After replacing the solenoids, all valves operated properly, as ECR-11 and 21 operate from the same control switch as ECR-13 and 23.

C&I-2 Turbine gland steam air ejector flow instrument, SFR-201, was indicating erratic air flow on recorder, MR-54. The air velocity sensor probe was removed and cleaned of excessive moisture. MR-54, indication for SFR-201 then returned to normal.

C&I-3 Fire protection water valve, ZRV-18, covering the fuel handling area exhaust charcoal filter,12-HV-AFX, would not open upon initiation of a manual signal. The valva was tested and functioned properly. A 10 Mf, 50V electrolytic capacitor on the supervisory circuit board was re-placed to restore proper valve actuation.

C&I-4 On a high Tavg signal, the rod control system responded to a load re-jection with steam dump valves open by moving the rods out. Trouble-shooting revealed an intermittent resistor, (R-4), in lead / lag signal processing module TY-412P. The resistor was replaced and the module was recalibrated.

After checking out the system, rod control was de-clared operable for the automatic mode.

C&I-5 The critical control room power inverter received an automatic bus transfer to the " emergency" power bus and would not switch back to the

" normal" bus.

Replacement of a failed constant voltage transformer, (M & E #25-495200), returned the inverter to operability. The inverter was then successfully transferred back to its " normal" bus power.
