EVENT _9_4-4 CAUSE: DURING MANUAL PLANT SHUTDOWN FOR A PLANNED REFUELING OUTAGE, AN AUTOMATIC REACTOR TRIP FROM LESS THAN 1% POWER WAS CAUSED BY A SPURIOUS SOURCE RANGE HIGH FLUX SIGNAL.

l l

CORRECTIVE ACTION: THE CAUSE OF THE AUTOMATIC TRIP WAS FOUND TO BE A LOOSE CAPACITOR IN THE NI-0032 NEUTRON DETECTOR PRE-AMPLIFIER THAT CAUSED A SIGNAL SPIKE. THE PRE-AMPLIFIER WAS REPLACED, NI-0032 WAS RETURNED TO SERVICE AND THE REFUELING OUTAGE CONTINUED AS SCHEDULED. NO MAJOR SAFETY RELATED CORRECTIVE MAINTENANCE WAS PERFORMED DURING THIS OUTAGE PERIOD.

CRITICAL PATH WAS: COOLDOWN TO 200 DEG. F, RCS CLEANUP, BATTERY REPLACEMENT, REMOVAL OF REACTOR VESSEL HEAD AND INTERNALS, CORE OFFLOAD, STATION AUXILIARY TRANSFORMER TIE IN, ECCS FLOW TEST, REACTOR VESSEL FOSAR.
