DUQUESNE LIGHT COMPANY Beaver Valley Power Station Narrative Summary Of Operating Experience - November,1979 Date Event November 1 to Station in Operational Mode 1 at nominal 35% reactor power.
November 6 November 7 to Station in Operational Mode 1 at nominal 40% reactor power.
November 10 The station was taken off-line at 2239 hours0.0259 days <br />0.622 hours <br />0.0037 weeks <br />8.519395e-4 months <br /> for planned maintenance in containment and the reactor was shutdown at 2240 hours0.0259 days <br />0.622 hours <br />0.0037 weeks <br />8.5232e-4 months <br /> on November 10. Maintained station in Operational Mode 3.
November 11 Station in Operational Mode 3 for maintenance. Entered containment to seal a steam leak, which was isolated at 1245 hours0.0144 days <br />0.346 hours <br />0.00206 weeks <br />4.737225e-4 months <br />. Reactor startup was commenced at 1356 hours0.0157 days <br />0.377 hours <br />0.00224 weeks <br />5.15958e-4 months <br /> and the reactor was critical at 1415 hours0.0164 days <br />0.393 hours <br />0.00234 weeks <br />5.384075e-4 months <br />. At 2013 houre, the reactor tripped due to low-low steam generator water level signal when operator had difficulty maintaining level in narrow range caused by interim lo-lo level setpoint of 20%. Reactor was critical again by 2127 hours0.0246 days <br />0.591 hours <br />0.00352 weeks <br />8.093235e-4 months <br />. The turbine roll-off occurred at 2150 hours0.0249 days <br />0.597 hours <br />0.00355 weeks <br />8.18075e-4 months <br /> and the generator was synchronized at 2232 hours0.0258 days <br />0.62 hours <br />0.00369 weeks <br />8.49276e-4 months <br />.
November 12 Station in Operational Mode 1 at nominal 35% reactor power.
November 13 to Station in Operational Mode 1 at nominal 40% reactor power.
November 21 November 22 Station in Operational Mode 1. Reduced the power level from nominal 40% to 35% reactor power at 0130 hours0.0015 days <br />0.0361 hours <br />2.149471e-4 weeks <br />4.9465e-5 months <br /> to conserve fuel.
November 23 Station in Operational Mode 1 at nominal 35% reactor power.
through Between approximately 0900 and 1030 hours0.0119 days <br />0.286 hours <br />0.0017 weeks <br />3.91915e-4 months <br /> on November 27, a November 30 potential safety problem was created when a motor operated valve from the refueling water storage tank was placed on clearan.:e while the diesel generator which provides emergency power for the redundant valve was also on clearance.

Major Safety-Related Maintenance - November, 1979
- 1. Radiation monitors for the containment internal atmosphere, the ventilation system exhaust and the liquid waste effluent discharge line were repaired and placed back into service.
- 2. A torque switch on the redundant supply valve from the refueling water storage tank to the high head charging pumps [MOV-CH-115D] was replaced when the valve would not close remotely.
