NIAGARAMOHAWKPOWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT 42 NARRATIVE OF OPERATING EXPERIENCE Nine Mile Point Unit 2 operated with a capacity factor of 70.91% (MDC - net) and an availability factor of 76.23% during the month of December 1991.

On December 7, 1991, at 0935 hours0.0108 days <br />0.26 hours <br />0.00155 weeks <br />3.557675e-4 months <br />, with the reactor mode switch in the "RUN" position (Mode 1),

and the plant operating at approximately 90 percent rated thermal power, Nine Mile Point Unit 2 experienced an Enginecrcd Safety Feature actuation. Specifically, an automatic reactor scram occurred caused by a Turbine Generator stop valve closure, which was initiated by (most probable cause) an Electrohydraulic Control (EHC)

System malfunction.

The root cause investigation is not yet completed; however, the most probable cause is a defective relay actuation.

The immediate corrective action was to respond to the reactor scram and turbine trip in accordance with plant procedures. A Work Request was issued to investigate the EHC malfunction, which lcd to the replacement of the relay board containing the suspected faulty relay (refer to LER 91-22 for further details).

On December 12, 1991, at 0322 hours0.00373 days <br />0.0894 hours <br />5.324074e-4 weeks <br />1.22521e-4 months <br />, with the reactor mode switch in the "RUN" position and the plant operating at approximately 55 percent rated thermal power, Nine Mile Point Unit 2 (NMP2) experienced a reactor scram on a reactor vessel low water level (Level 3) signal. Specifically, following the startup of Feedwater System pump 2FWS-P1A in support of raising plant power, a Condensate System (CNM) and Fecdwater System (FWS) transient occurred, resulting in the loss of both FWS pumps. Reactor vessel water level lowered to 159.3 inches (Level 3 trip setpoint), initiating an automatic reactor scram. signal. On December 12, 1991, at 1023 hours0.0118 days <br />0.284 hours <br />0.00169 weeks <br />3.892515e-4 months <br />, while operators were attempting to return the Reactor Water Cleanup (WCS) System to an operable status following the scram, the WCS isolated on a high differential flow signal (Engineered Safety Feature actuation).

The root cause for the reactor scram was determined to be poor work practices. The root cause for the WCS isolation was inadequate system design.

Immediate actions included restoring reactor vessel inventory and commencing a controlled plant shutdown. Additional corrective actions included: 1) administering disciplinary action for individuals involved in the scram; 2) evaluating and revising Operating Procedure N2-OP-3, "Condensate and Fccdwater System";

and 3) troubleshooting electrical circuitry for condensate pump 2CNM-P1C; and 4) evaluating WCS isolation circuitry (refer to LER 91-23 for further details).

Other capacity losses during the month of December 1991 were due to power reductions to repair steam leaks through the packing of several valves assocated with the Moisture Separator Rehcaters, Condenser tube fouling, Cooling Tower inefficiency, and Feedwater Heater Cycle inefficiency resulting in slightly low final feedwater temperature.

There were no challenges to safety relief valves during this reporting period.

SUMMARY

OF CHALLENGES TO SAFETY RELIEF VALVES DURING 1991 In accordance with the Nine Mile Point Nuclear Station - Unit ¹2 Technical Specification 6.9.1.5c, documentation of all challenges to safety relief valves during the reporting calendar year 1991 is hereby presented:

At 0548 hours0.00634 days <br />0.152 hours <br />9.060847e-4 weeks <br />2.08514e-4 months <br /> on August 13, 1991, Nine Mile Point Unit 2 (NMP2) experienced a turbine trip and reactor scram when the "B" Phase Main Transformer developed an internal fault. The transformer fault created an electrical disturbance in the station electrical distribution system resulting in the loss of five non-safety related Uninterruptible Power Supplies (UPS). As a result, the Control Room lost annunciation and most Balance of Plant (BOP) instrumentation. The conditions described in LER 91-17 mandated entry into a Site Area Emergency as speciTied by the Site Emergency Plan. Prior to the event, NMP2 was in operaitonal condition 1 (RUN) at 100% rated thermal power.

During the event, two Main Steam System (MSS) Safety Relief Valves (SRVs), 2MSS*PSV128 and 2MSS'PSV133, lifted for approximately 30 seconds, to limit reactor pressure to 1070 psig; both valves functioned as designed.

There were no other challenges to the safety relief valves at Nine Mile Point Unit ¹2 during the calendar year 1991.
