I OPFRATIONS-

SUMMARY

APRIL 1989 The unit entered April operating at 100% power producing approximately 890 MWe. Plant power was reduced for four hours on April 2, 1989 following the shaft failure of the "A" heater drain pump. The "C" heater drain pump was placed in service and the plant was returned to 100% power. The "A" heater-drain pump was returned to operable status on April 24, 1989. The-unit closed the month at 100% power.

MAJOR SAFETY RELATED MAINTENANCE During April, the following major maintenance activities were performed on safety-related equipment:

Air Intake Tunnel - Fire System The Air Intake Tunnel fire protection system was repaired in April. Following a halon actuation, inspections revealed that the actuation was caused by a bad ultraviolet detector. The detector was replaced and the system was returned to service. 'The system then actuated again due to moisture in the relays. The relays were replaced and the system was-returned to service.
