The Reactor tripped at 1806 hours0.0209 days <br />0.502 hours <br />0.00299 weeks <br />6.87183e-4 months <br /> when the number two main turbine stop valve went shut with the turbine first stage pressure above P-13 setpoint during shell warming.

The Reactor was restarted and entered into Mode 2 at 1910 hours0.0221 days <br />0.531 hours <br />0.00316 weeks <br />7.26755e-4 months <br />.

03-04-82 The Reactor entered Mode 1 and the turbine was rolled at 0045 hours5.208333e-4 days <br />0.0125 hours <br />7.440476e-5 weeks <br />1.71225e-5 months <br /> The turbine was manually tripped at 0214 hours0.00248 days <br />0.0594 hours <br />3.53836e-4 weeks <br />8.1427e-5 months <br /> to investigate an oil flow

problem with a turbine bearing. The problem was resolved and the turbine rolled at 0424 hours0.00491 days <br />0.118 hours <br />7.010582e-4 weeks <br />1.61332e-4 months <br />. The turbine generator was removed from the grid after holding 25% power for three hours in preparation for overspeed testing.

The overspeed tests were successful and the Unit was paralleled to the grid at 1614 hours0.0187 days <br />0.448 hours <br />0.00267 weeks <br />6.14127e-4 months <br />.

The low-low level resulted i

from a problem with the turbine control system.

The problem was resolved and the Reactor was again taken critical at 1554 hours0.018 days <br />0.432 hours <br />0.00257 weeks <br />5.91297e-4 months <br />.

Corrected the electrolyte specific gravity and performed battery service test.

M-2 The reciprocating charging pump had a stuffing box leak.

Replaced the stuffing box on No. 4 cylinder.

Repacked No. 3 and No. 4 cylinders.

Had pump tested.

M-3 No. 4 steam generator stop valve dump valves, MRV-241 and MRV-242 had seat ieakage.

Replaced the valves' stem, plug and seat and had the valves tested.

M-4 Suction valves on the north and south waste gas compressors, RRV-378 and 388 were leaking by.

Replaced the valve diaphragms and had valves tested.

C&I-l Auxiliary Spray Valve, QRV-51 would not close. A new Asco solenoid valve was installed and proper operation verified.

C&I-2 Source range detector, N-32, when blocking a P-6 c.igh voltage did not turn off. Troubleshooting revealed a faulty capacitor on the high voltage cut-off board. The board was replaced and the unit was checked for proper operation.

C&I-3 Loss of the UVcoil output on the Solid State Protection System Train "A".

Troubleshooting revealed a bad UV card. The card was replaced and re-quired surveillance tests were performed sn Train "A" to verify proper operation.

C&I-4 Group 2 on Shutdown and Control Banks B and Group 2 on Control Bank D would not move. Troubleshooting revealed a defective supervisory card.

This was replaced with a spare.

The equipment was then verified operable and returned to service.

C&I-5 The west RHR heat exchanger outlet flow instrument, IFI-321 was reading 2900 gpm flow with the RHR pump not operating. The flow sensor strain gauge and its associated electronics card were replaced to restore proper indication to IFI-321.

C&I-6 Diesel generator l AB had a damaged voltage regulator relay mounting.

The relay was resoldered in its mounting and was checked to be sure the mounting was secure. The diesel generator was tested successfully after 4

completing repairs to the relay.
