Davis-Besse Nuclear Plant Completes Planned Outage

FirstEnergy's Davis-Besse nuclear plant in Ohio

The single-unit Davis-Besse nuclear power plant in Ohio returned to service following a planned refueling and maintenance outage.

The 908-MW unit was taken offline March 28 and is currently operating at 45 percent power. It is expected to reach full power in the next week. During the outage, about one-third of the plant’s 177 fuel assemblies were exchanged. FirstEnergy (NYSE: FE) also performed numerous inspections and preventative maintenance and improvement projects, including examining the unit’s reactor head and vessel, turbine, electrical generator and various pumps, motors and valves.

The plant’s two steam generators, which convert heated water to super-heated steam that turns the plant’s turbines to create electricity, were inspected as the plant prepares to enter its 20-year period of extended operation. The generators were installed in 2014. In addition, to of the plant’s four, 50-ton, 16-foot tall reactor coolant pump motors were replaced, and a new emergency feedwater facility was built to provide additional backup supply of power and water to the plant. The previous refueling was in May 2014.
