Davis-Besse Nuclear Plant Down for Refueling & Replacement Project

Davis-Besse Nuclear Station down for refueling and replacement outage

FirstEnergy Nuclear Operating Co. (FENOC), a subsidiary of FirstEnergy Corp. (NYSE: FE), shut down the 908-MW Davis-Besse Nuclear Power Station in Ohio for a scheduled refueling and maintenance outage.

While the unit is down, about a third of the reactor’s 177 fuel assemblies will be replaced. Workers will also perform preventive maintenance and safety inspections on major components, including pumps, valves, reactor vessel, steam generators and the cooling tower.

A major project will be replacing two of the four reactor coolant pump motors. The 50-ton, 16-foot tall, 9,000 horsepower motors drive large pumps capable of pushing more than 100,000 gallons of water per minute through the reactor vessel. More than 1,000 temporary contractor workers and FENOC and FirstEnergy employees will supplement the Davis-Besse workforce during the outage.

The last refueling outage at Davis-Besse was completed in May 2014. The reactor received a 20-year license extension from the U.S. Nuclear Regulatory Commission in December 2015.
