C&I-l The turbine driven auxiliary feedpump tripped before stabiliz ng at rated speed. One of the latch coils of the trip-throttle valve solenoid was found burned out. Both coils were replaced. The TDAFP was successfully retested.
C&I-2 Annunciator "RTD Lypass Manifold Low-Flow", was received. The flow transmitter's low side vent plug was found to be leaking and re-sulting reactor coolant leakage shorted the terminal box causing the alarm. The leak was repaired, the box was dried of water and the alarm cleared.
C&I-3 The CD2 battery charger was found to have a low voltage output.
Capacitors on three SCR firing controls were bad, and were replaced.
The charger was operated in service for two hours, then declared operable.
