FirstEnergy Corp.’s (NYSE:FE) single-unit Davis-Besse nuclear power plant in Ohio automatically shut down June 29 after workers found a problem with a terminal box that powers one of four reactor coolant pumps, according to the Toledo Blade.

During the trip, a feedwater valve did not respond as expected and was placed in manual control, according to a report with the U.S. Nuclear Regulatory Commission (NRC). All other systems have functioned as designed.

Workers said there was a problem with electrical wiring that connects the box to a motor that runs one of four pumps, the article said. The wiring must be repaired and there is no word on when the reactor is expected to return to service.
