FirstEnergy Nuclear Operating Company, a subsidiary of FirstEnergy Corp., announced Monday that its Beaver Valley Power Station Unit 2 in Shippingport, Pa., is undergoing scheduled refueling and maintenance.
The station shut down early Monday morning for replacement of fuel assemblies, safety inspections of the unit's reactor vessel head, turbine and electrical generator and preventative maintenance on major components including pumps, valves and the cooling tower.
A FirstEnergy spokeswoman said customers will see no difference with the plant off line. The company gave no timeframe for when the plant will come back into service.
More than 1,000 temporary contractors and FirstEnergy employees, including 130 workers from the company's W.H. Sammis Plant, will supplement the Beaver Valley work force during the outage.
The 904-megawatt Beaver Valley Unit 2 operated safely and reliably for 532 consecutive days and has generated more than 12 million megawatt hours of electricity since the completion of its last refueling in April 2011, according to the company.
The FirstEnergy Nuclear Operating Company subsidiary also operates Ohio's Davis-Besse Nuclear Power Station in Oak Harbor and the Perry Nuclear Power Plant.
