FirstEnergy Nuclear Operating Company announced the Davis-Besse Nuclear Power Station in Oak Harbor, Ohio, returned to service following a shutdown for refueling and maintenance. The 24-day outage marks the shortest refueling outage in Davis-Besse’s 41 years of operation, with the previous record being 38 days in 2012.
The 908-MW plant is currently operating at 20 percent power, with the plant gradually ramping back up to full power production.
While the unit was shut down, approximately one-third of the unit’s 177 fuel assemblies were exchanged. In addition, more than 1,200 work activities associated with numerous inspections, preventive maintenance and improvement projects were completed, including examinations of various pumps and valves, the reactor vessel, steam generators, turbine generator and cooling tower.
“Davis-Besse’s solid outage performance reflects the hard work and dedication of the plant employees and more than 1,000 temporary contract workers and FENOC personnel who assisted with the refueling outage,” said FENOC Chief Operating Officer Paul Harden. “Thanks to their good work, Davis-Besse will operate at peak efficiency while generating safe, reliable, secure and clean electricity.”
Prior to the outage, Davis-Besse generated more than 13.8 million MWh of electricity since the completion of its last refueling in May 2016.
