May 1990 Limerick Generating Station Unit 1 l May 1 through May 31,1990 l

1. Narrative Summary of Onoratina Erneriences Limerick Unit 1 began the month of May at a nominal 100% of rated thermal power. On May 5,  !

reactor power was reduced to 36% to allow individual removal of the reactor recirculation pump i motor generator (M.G) set from service for generator brush replacement. On May 6 following M- '

G set return to service and recalibration of nuclear instrumentation for two recirculation loop l operation, reactor power was restored to 100%. On May 9, reactor power was reduced to 82% to perform a control rod pattern adjustment. Limerick Unit 1 ended the month of May at a nominal  !

100% of rated thermal power.  ;

Operational events that occurred during the month of May included:

On May 23, the Unit 1 HPCI was blocked for 1 & C work on a flow transmitter. Following completion of the work, the pump was placed in service per ST-6 055 230-1. The test wh completed satisfactorily; however, a leak on the booster pump seal cooling water line was observed. Following testing, HPCI was returned to an operable status. On May 25. HP.QI was blocked and the booster pump seal cooling water leak was repaired. Following repair HPCI was placed in service, operated satisfactorily, and subsequently returned to an operable status, ll, mat i FNGES TO MAIN STEAM SAFETY RELIEF VALVES r There were no challenges to the Main Steam Relief Valves during the month of May.

1. Narrative Summarv of Onoratina Exr,st;ences Limerick Unit 2 began the month of May at a nominal 100% of rated therrnal power. On May 6, reactor power was reduced briefly to 94% to perform a control rod pattem adjustment. On May 19, reactor power was reduced to 62% for ALARA considerations while performing maintenance on the cordenser hotwell level transmitter and the '281' moisture separator drain valve air line. Limerick Unit 2 ended the month of May at a nominal 100% of rated thermal power.

Operational events that occurred during the month of May included:

I The D21 Diesel Generator was declared inoperable on May 17 upon discovery that the seismic qualifications for the installed speed signal Generator could not be verified. The remaining Unit 2 Diesel Generators were placed in service to verity operability to sati$

Technical Specifications. On May 18, the D21 Diesel Generator was declared operable after documentation verlfled that the speed signal generator had seismic qualifications. .

II. Challennes to Main Steam Safety Relief Valves There were no challenges to the Main Steam Safety Relief Valves during the month of May.
