The FirstEnergy (NYSE:FE) Davis Besse nuclear plant in Ohio appears to be returning to service after experiencing an unplanned outage on Saturday, Sept. 10.
Davis-Besse was listed at 19% power early Sept. 22, according to data from the Nuclear Regulatory Commission (NRC).
The unit had gone offline after water from heavy rains moving through the area entered the turbine building through a roof vent that didn’t fully close.
In addition to replacing affected components, workers also used the unplanned outage to replace a valve on the pressurizer, which is part of the reactor coolant system, according to FirstEnergy.
Davis-Besse is a roughly 900-MW pressurized water reactor (PWR) located in Oak Harbor, Ohio.
