l OPERATIONS

SUMMARY

MARCH 1989 The unit entered the month operating at 100% reactor power and producing approximately 880 MWe. The plant continued operating at 100% power throughout the month.

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

Instrument Air Dryer IA-Q-1 Instrument Air Dryer IA-Q-1 work was completed in March. A stainless steel inlet air manifold fabricated from bar stock was welded into the system.

Portions of the inlet air pipi.ng and exhaust piping were also replaced with stainless steel. All welds were NDE inspected and the air dryer was returned to service.

Nuclear Service River Water Pump NR-P-1B Nuclear Service River Water Pump NR-P-1B was repaired during March.

The pump was taken out of service for overhaul because of high vibration. The motor was removed and the pump disassembled.

Inspections revealed excessive clearances in the bearings. The pump was reassembled using new repair parts and a new bowl assembly.

The motor was disassembled, cleaned and reassembled using new bearings. The pump and motor were then reinstalled, aligned, coupled and tested. All tests were satisfactory and NR-P-1B was returned to service.

Nuclear Service River Water Pump NS-P-1A Nuclear Service Closed Cooling Water Pump NS-P-1A was removed from service in March to repair a mechanical seal leak.

The pump was uncoupled, disassembled, cleaned, and inspected.

Inspections revealed normal wear on the seal faces and the pump was reassembled using a new mechanical seal.

The pump was aligned, coupled to the motor and test run. All tests were satisfactory and NS-P-1A was returned to service.
