FirstEnergy Nuclear Operating Company (FENOC) has shut down its Davis-Besse nuclear power station in Oak Harbor, Ohio, US, for scheduled refueling and maintenance outage.

During outage, the company will install new steam generators to enhance safe and reliable operation of the power plant.

Manufactured by The Babcock and Wilcox Company at its facility Ontario, Canada, the steam generators function as heat exchangers, producing the superheated steam that is used to drive the turbine generator, which ultimately produces electricity.

Davis-Besse Nuclear Power Station site vice president Ray Lieb said the new steam generators are expected to provide additional margins of safety and reliability for the long-term operation of the nuclear plant.

"The investment in these new components, along with the other work we will complete during the refueling outage, supports our commitment to remaining an integral part of northwest Ohio’s economy for many decades to come," Lieb added.

Other work scheduled during outage includes replacement of about a third of the unit’s 177 fuel assemblies, several safety inspections and preventative maintenance activities to promote continued safe and reliable operations of major components including pumps, valves and motors across the plant.
