DUQUESNE LIGHT COMPANY Beaver Valley Power Station NARRATIVE

SUMMARY

OF MONTHLY OPERATING EXPERIENCE - August, 1981 August 1 Station in Operational Mode 1 at nominal full power.

through August 13 August 14 Station in Operational Mode 1 at nominal full power. At 1226 hours0.0142 days 0.341 hours 0.00203 weeks 4.66493e-4 months through a reactor trip occurred due to a turbine trip.

The turbine electro-August 15 hydraulic control (EHC) system hydraulic fluid pressure decreased when the EHC fluid pump tripped and the scandby EH fluid pump failed to start automatically. Reactor start-up was commenced at 1450 hours0.0168 days 0.403 hours 0.0024 weeks 5.51725e-4 months , the reactor was critical at 1510 hours0.0175 days 0.419 hours 0.0025 weeks 5.74555e-4 months and the main unit generator was synchronized at 2007 hours0.0232 days 0.558 hours 0.00332 weeks 7.636635e-4 months . A reactor trip occurred at 22% reactor power due to Ica-low level in the 1A Steam Generator while transferring from the bypass flow controllers to the main feedwater flow controllers.

The reactor was critical at 2217 hours0.0257 days 0.616 hours 0.00367 weeks 8.435685e-4 months and the main unit was synchronized at 0049 hours5.671296e-4 days 0.0136 hours 8.101852e-5 weeks 1.86445e-5 months on August 15, and power level was stabilized at full power by mid-morning.

August 16 Station in Operational Mode 1 at nominal full power.

through August 25 August 26 Station in Operational Mode 1 at nominal full power. At 2223 hours0.0257 days 0.618 hours 0.00368 weeks 8.458515e-4 months a through reactor trip occurred due to a turbina trip. The turbine EHC system August 27 control signals were causing the turbine throttle valves to modulate.

Reactor start-up was commenced at 0145 hours0.00168 days 0.0403 hours 2.397487e-4 weeks 5.51725e-5 months on August 27 and the reactor was critical at 0204 hours0.00236 days 0.0567 hours 3.373016e-4 weeks 7.7622e-5 months .

Repairs to the turbine EHC system were completed at 1405 hours0.0163 days 0.39 hours 0.00232 weeks 5.346025e-4 months . At 1640 hours0.019 days 0.456 hours 0.00271 weeks 6.2402e-4 months a reactor trip occurred due to low-low level in the 1C Steam Generator. The reactor start-up was commenced at 2040 hours0.0236 days 0.567 hours 0.00337 weeks 7.7622e-4 months , the reactor was critical at 2102 hours0.0243 days 0.584 hours 0.00348 weeks 7.99811e-4 months and the main unit generator was synchronized at 2241 hours0.0259 days 0.623 hours 0.00371 weeks 8.527005e-4 months .

August 28 Station in Operational Mode 1 with load increase to full power in progress.

August 29 Station in Operational Mode 1 at nominal full power.
