FirstEnergy Nuclear Operating Company (FENOC), a subsidiary of FirstEnergy, announced its Beaver Valley Power Station Unit 1 in Shippingport was shut down for scheduled refueling and maintenance.
While the unit is offline, one-third of the 157 fuel assemblies will be replaced and numerous inspections of the plant's reactor vessel will be conducted. Preventive maintenance to ensure continued safe and reliable operations also will be performed on major components including the plant's three steam generators as well as various pumps, motors, valves and the cooling tower.
More than 1,000 temporary contractor workers and FENOC and FirstEnergy employees will supplement the Beaver Valley workforce during the outage.
The 939-megawatt Beaver Valley Unit 1 has operated safely and reliably, generating more than 10.5 million megawatt hours of electricity since the completion of its last refueling in May 2015.
