Refueling, steam generator replacement completed at Davis-Besse nuclear plant

Davis-Besse nuclear plant in Ohio

The Davis-Besse Nuclear Power Station in Ohio returned to service after a refueling and steam generator replacement outage.

The $600 million outage at the 900-MW unit started Feb. 1. Workers exchanged 80 of the plant’s 177 fuel assemblies and performed safety inspections and preventative maintenance activities.

Plant owner FirstEnergy Nuclear Operating Co. (FENOC) replaced two steam generators during the outage. The generators function as heat exchangers, producing the steam that is used to drive the turbine generator. Each Babcock & Wilcox Canada-designed generator measures 74 feet in length, 12 feet in diameter and weighs 470 tons. FENOC expected the outage would bring in $108 million, with overall economic benefits expected to exceed $150 million statewide.
