Description:
electrical contacts were exposed to a water leak fro = the overhead.
All contacts were found to be corroded which resulted in a invalid logic signal indicating the valve was shut. The pu=p logic sensed no suction path available and would not allow the pump to start.
Corrective Action:
The wires associated with the pu=p suction valvo positten for t'-
logic to LA RRR pu=p were re=aved and the pu=p was tested satis-factorily. A caution tag was placed on RHR LA pump control switch to ensure the operators are aware the suction valve logic input is re=oved.
Action to Prevent a Recurrence:
Instructors will be sent to the =aintenance fore =an giving guidance on protecting equip =ent, which has been left open to the environ =ent, while a portion of the equipment has been re=oved for repair.
