ZZ ZZZZZZ Turbine / Reactor trip.

The turbine trip was caused by low condenser vac-uum.

Condenser tube leakage repairs were in progress and the low vacuum condition resulted when removing a loose tube plug at a location where the tube had previously been removed.

The unit was returned to service the same day.

100% reactor power was reached on 801213.

HA GENERA The unit tripped from 100% power due l

to loss of generator excitation. The reactor trip was initiated by the reactor coolant pump bus undervoltage relays and wac followed by blackout, start-up of the emergency diesel gen-erators and load sequencing. The loss of excitation was caused by a failure of the pilot exciter which was found on fire. The exact reason for the pilot exciter fire nas not been determined. The unit was re-turned to service on 801216 and brought to 100% power on 801217.

1 of 2 MONTHLY OPERATING ACTIVITIES - DECEMBER, 1980 Highlights:

The Unit entered this reporting period in Mode 5 in the progress of running the Reactor Coolant Pumps and venting the Reactor Coolant System. The Unit had tripped from 100% power at 2057, Saturday, October 18, 1980. The cause of the trip was identi-fled as a ground in the Main Turbine Generator.

The Unit reached 100% power at 1925, Thursday, December 11, 1980.

There were three outages of the Reactor and Turbine Generator Unit during the reporting period.

l Sunmary:

12/12/80 - At 0427, the Unit tripped from 100% power due to Low Vacuum in "C" Condenser. Tube leakage repairs were in progress in "C" South Condenser.

The Reactor was critical at 1436, and the Generator l

1 paralleled at 1643. The Unit was loaded to 100%

at 1720 on 12-13-80, 12/14/80 - At 2218, the Unit tripped from 100% power. The l

trip was caused by a loss of field excitation which

}

was a result of a fire at the Pilot Exciter. The trip was accompanied with an Emergency Bus Blackout and both Diesels running. The Emergency Buses were returned to normal reserve power at 2305.

The Reactor was critical at 0104 on 12-16-80 and the Generator paralleled at 0230. The Unit was loaded to 100% by 0500, on 12-17-80.
