March 1996 The reactor operated continuously in March with the following exceptions: four shutdowns for scheduled maintenance and refueling; one unscheduled shutdown.
On March 29, a manual scram was initiated by the duty operator after receiving and verifying a alarm indicating that the fire main water pressure had dropped below the pressure sufTicient to supply at least 1,000 gallons per minute to the emergency pool fill system as specified by Technical Specification 3.1(c). The loss of fire main system pressure was caused by a fire hydrant pipe rupture during excavation remote from the reactor facility. After the broken fire hydrant was repaired, fire main water pressure was retumed to normal and the reactor was refueled and returned to j
operation.
Major maintenance items for the month included: shipping sixteen spent fuel elements; replacing the cables to the Channel 4 nuclear instrument detector; loading two new deionization beds for use on the pool and primary systems.
