FirstEnergy Nuclear Operating Co., a subsidiary of FirstEnergy Corp., announced its Beaver Valley Power Station Unit 1 in Shippingport, Pa., shut down earlier today for scheduled refueling and maintenance.
While the unit is off line, 65 of the 157 fuel assemblies will be replaced and numerous safety inspections will be conducted, including inspections of the unit’s high pressure turbine, main electrical generator and containment liner.
In addition, preventative maintenance to ensure continued safe and reliable operations will be performed on major components, including pumps, valves and the cooling tower.
More than 1,000 temporary contractors and FENOC employees from the company’s other nuclear plants will supplement the Beaver Valley workforce during the outage.
The 911-megawatt unit operated safely and reliably for 359 consecutive days and has generated more than 9.3 million megawatt hours of electricity since the completion of its last refueling in November 2010.
The plant also posted an industry top-decile forced-loss rate of 0.01 percent during the past 18 months of operation (forced-loss rate measures a unit’s unplanned outages and power reductions).
