. CAUSE DESCRIPTION ANO CORRECTIVE ACTIONS h li l o l l This event occurred because a maintenance technician inadvertent 1v shorted an elec-I trical lead in the pump control loop circuitry which tripped the motor generator unit.g g

The motor generator and pump were then successfully restarted and returned to normal g'

,,,,,; c'peration. The involved technician and all other maintenance technicians have been g

counseled to exercise extreme care when investigating problems with the control 80 S g cuitry of the reactor recircu ion,y g.
