Limerick Generating Station Monthly operating Report For Units 1 and 2 Enclosed are the monthly operating reports for Lincrick Units 1 and 2 for the month of March, 1991 forwarded pursuant to Technical Specification 6.9.1.6. Also enclosed is Revision 1 to the January, 1991 and February, 1991 for Limerick Unit I which corrects the year-to-dato and cumulativo figures for generator on line and forced outage hours. This error occurred as a result of a . computational error for January forced outage hours which has been corrected. We regret any inconvenience this error may have caused.

1. NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 1 began the month of March at a nominal 100% of rated thermal power. Thore wuro four (4) briot power reductions and ono (1) extended power reduction during the month.

On March 1,14,19, and 27, reactor power was reduced to approximately 85% to perform main turbino stop and control valvo tests. Additionally, on March 0, reactor power was reduced to 80%

to perform main turbino stop and control valve testing Upon completion of testing, reactor power romalnod reduced duo to high reactor water conductivity. Reactor power was gradually increased following correctivo action, achloving 100% on March 14. Unit 1 ondod the month at 100% of rated thermal power.

11. CHALLENGES TO MAIN STEAM SAFETY REllEF VALVES There woro no challongos to the Main Steam Safoty Rolio! Valves during the month of March.

1. NARRATIVE

SUMMARY

OF OPERATING EXPERIENQES Umorick Unit 2 began the month of March at a nominal 100% of rated thermal power. On March 1, reactor power was reduced to 88% for a control rod pattem adjustment and to perform main turbino stop and control valve testing. On March 8, reactor power was reduced to 87% to perform main turbine stop and control valve testing. On March 14, at 0200 hours0.00231 days 0.0556 hours 3.306878e-4 weeks 7.61e-5 months , reactor power was reduced to 48% duo to a loss of cooling to the isophaso bus. At 0704 hours0.00815 days 0.196 hours 0.00116 weeks 2.67872e-4 months , reactor power was reduced to 20% and the turbine generator tripped with main steam bypassed to tno condensor, Upon completion of Inspection and corrective actions, on March 15 at 0430 hours0.00498 days 0.119 hours 7.109788e-4 weeks 1.63615e-4 months the gonorator was synchronized to the grid. Reactor power achloved 100% on March 15, but gradually decreased to 88% over the next soveral days due to the control rod pattern. On March -

17, reactor power was reduced to 80% and all remaining partially insorted control rods were fully withdrawn and a power levol of 97% was achloved and end of cycle fuel coast down then began.

Or, March 22 at 1219 hours0.0141 days 0.339 hours 0.00202 weeks 4.638295e-4 months , the main turbino generator was tripped and the reactor scrammed from 96% to begin the first refueling outage. Unit 2 ontored Operational Condition (OPCCN) 4 on March 22, OPCON 5 on March 26, and OPCON 5* on March 30. Unit 2 onded the month of March in OPCON 5* with fuel unloading in progress, in day 9 of a 75 day refueling outage.

NOTE: OPCON 5* equates to fuel movement.

Operational events that occurred during the month of march included:

- On March 22, a manual Main Turbine trip on Unit 2 was initiated por procedures SP T.

007, Unit 2 Main Turbine Trip and SP 099 Unit 2 Main Steam Piping Dynamic Loading During Main Turbino Stop Valve and Control Valve Closures. The reactor scrammed due to Main Turbine Stop Valvo Fast Closure. The reactor scram was successful and the Foodwater Level Control System responded in automatic to rostore reactor water lovel to normal without operator action por SP-T-007. The test was satisfactorily complotoly and a normal plant cooldown commenced in preparation for the first refueling outage.

- On March 24, during the performance of the DMslon 111125 VDC Safeguard Battery 18 Month inspection, a 300 amp fuse blew during load testing, causing an undervoltage condition on the bus. This caused the '2A' RPS Breaker Panol (2PC240) shunt trip coil relay to trip one of the serios output breakers due to an apparent undervoltage condition.

This condition caused the doenergization of the '2A' RPS and UPS Distribution Panel, which resulted in numerous NSSSS isolation signals and an 'A' channel scram signal.

-This event resulted in Isolations of shutdown cooling, RWCU, instrument gas, drywell chilled water, and reactor enclosure ventilation. The RPS series breaker was reclosed and the '2B' loop of shutdown cooling was retumed to service within 24 minutos. Reactor coolant temperature increased from 124 dog. F to 141 deg. F and reactor lovel increased from 85 inches to 92 inches during this event. It was determined that the evont was initiated by faulty test equipment. A 4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months notification was made to the NRC.

- On March 24, during the installation of a Temporary Circuit Alteration (TCA) In the Redundant Reactivity Control System (RRCS) cabinet in the Auxillary Equ!pment Room (AER), RRCS Initiated a DMslon 1 Altemate Rod insertion (ARI) due to a falso low low (-

38 inches) reactor level signal. The ARI initiation caused the Scram Dischargo Volume (SDV) vent and drains to closo. The SDV level increased to tho SDV high level scram setpoint and a full scram signal was generated. The scram signal was subsequently resot.

A 4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months notification to the NRC was made.
