single tube located _ in Row 1, Column 71, Steam Generator 2-1 was identi-fied as leaking. Eddy current l

testing showed an indication in the Row 1, Column 72 tube. Both tubes were plugged using mechanical plugs.

The Unit was returned to service on 820818 and reached 100% reactor power on 820819.

(616) 465-5901 Date: 9/8/82 Page: 1 of 2 MONTHLY OPERATING ACTIVITIES - AUGUST 1982 Highlights: The Unit entered the reoorting period at 100% power. On July 31, 1982, the primary to secondary leak rate was calculated to bc 0,17 GPM. The Unit was shut down to Mode 5.

Testing of the number 21 steam generator determined that tube number 71 in row I was leaking; this tube was plugged. The Unit was restarted and paralled to the grid on August 18, 1982. One hundred pr.rcent power was reached at 0504 hours0.00583 days <br />0.14 hours <br />8.333333e-4 weeks <br />1.91772e-4 months <br />, August 19, 1982. On August 24, 1982, the Unit tripped from a reactor trip caused by loss of CRID IV inverter (vital instrument power supply).

Repairs were made to the inverter and the Unit was paralled to the grid at 2225 hours0.0258 days <br />0.618 hours <br />0.00368 weeks <br />8.466125e-4 months <br />, August 24, 1982.

Svensson TELEPHONE (616) 465-5901 PAGE 1 of 2 MAJOR SAFETY-RELATED MAINTENANCE AUGUST,1982 M-1 RHR cooldown motor-operated containment isolation valve, ICM-lll, had a body-to-bonnet leak. Replaced the bonnet gasket and had the valve tested.

M-2 CVCS letdown system regulating valves QRV-160 and 162, had body-to-bonnet leaks.

Inspected valve internals and had bonnet studs in-spected. Replaced the gaskets and had the valves tested.

M-3 Auxiliary pressurizer spray regulating valve, QRV-51, had a body-to-bonnet leak. Replaced the valve gaskets and the bonnet studs and nuts. Had the valve tested.

M-4 The vent valve for the South seal water injection filter, CS-343S, was leaking by. Replaced the valve bonnet and stem. Repacked the valve.

M-5 CVCS letdown regulating valve, QRV-161, had a body-to-bonnet leak.

Replaced the valve gaskets and had the valve tested.

C&I-l Reactor coolant loop 3 overtemperature AT setpoint had drifted high.

Troubleshooting the modules comprising the system disclosed that gain adjustment K1 of module TY-431L had drifted. The module was replaced with a new unit and was recalibrated to specifications.

C&I-2 Unit vent air particulate radiation monitor R-25, sample pump, could not be started from the control room.

Investigation revealed that the paper drive motor ccnnecting wires had shorted together and had burned off, tripping the circuit breaker. The wires were repaired and the breaker was reset without further incident.

l C&I-3 Containment sump level indication loops, NLA-310 and NLI-311, had their transmitters purged of entrapped air which had entered from the sensing line fill with Dow Corning 702 oil.

It is felt that several such purges will eliminate incorrect indications on these instruments as the en-trained air is released from solution slowly over several weeks' period and must be purged out.

C&I-4 Boron injection tank temperature indication was erratic and giving a spurious high temperature alarm. The resistance to current converter module in the resistance temperature detector circuit was replaced to restore correct temperature readout to the BIT.

50 - 316 UNIT NAME D. C. Cook - Unit No. 2 DATE 9-13-82 COMPLETED BY B. A. Svensson TELEPHONE (616) 465-5901 PAGE 2 of 2 MAJOR SAFETY-RELATED MAINTENANCE AUGUST,1982 C&I-5 Source range detector, N-31, was indicating a neutron level and was bringing in a "high flux at shutdown" alarm while the unit was at 100% power. During the outage the N-31 high voltage power supply was replaced, and H.V. cable, signal cable and detector cable end termina-tions were replaced to eliminate noise on the N-31 channel. Proper plateaus were run on the high voltage and discriminator voltage to verify operability.

C&I-6 Containment air particulate monitor, R-ll, " filter paper not in motion" alarm was received. Repairs were made to the paper drive mechanism.

A subsequent check verified that the filter paper was spooling properly.

C&I-7 Valve QRV-62, normal charging line to reactor coolant loop 4 cold leg could not be closed from the control room. When the emergency air station was connected, QRV-62 closed properly. Upon investigation, the cover plate and retaining caps were found to be missing from actu-ating solenoid valve, XS0-510. When these parts were replaced, QRV-62 functioned correctly.

C&I-8 Control room instrument power distribution Bus IV, power inverter failed. The inverter oscillator circuit board and fuses were replaced to restore operability to CRID IV inverter.

C&I-9 Battery charger, 2-AB-2, would not enter the " equalize charge" mode of operation. The problem was traced to a defective " equalize charge" timer. Replacement of the timer returned the charger to operability.

C&I-10 In the " steam pressure" mode of operation, the steam dump control was erratic in " automatic". Electro-pneumatic transducer, EPT-110, was recalibrated and the controller for the three cooldown valves was aligned. Proper operation of the steam dump control was verified as the unit was being brought up to power.
