May 27--SHIPPINGPORT -- Beaver Valley Nuclear Power Station's Unit 1 returned to service Sunday after being shut down late last month for refueling and maintenance, according to owner FirstEnergy Corp.
Unit 1 was restarted shortly before 10 a.m. Sunday. It was shut down April 25 for scheduled work unrelated to an April 16 incident in which one of two condensate pumps in Unit 1 malfunctioned, causing an unexpected outage.
Akron, Ohio-based FirstEnergy said that 61 of 157 fuel assemblies were replaced during the planned shutdown, which also allowed the company to conduct safety inspections, preventative maintenance and improvement projects.
FirstEnergy spokeswoman Jennifer Young said the monthlong shutdown was "typical for a standard refueling and maintenance outage."
More than 1,000 temporary contract workers and company employees augmented the plant's existing staff during the shutdown. Unit 1, a 939-megawatt unit, generated more than 11 million megawatt hours of electricity since its last refueling in November 2013, the company said.
