| A nuclear power plant in northern Ohio has been shut down because a coolant pump malfunctioned - but officials say there's no threat to public safety. The Davis-Besse Nuclear Power Station has been shut down since Saturday night after trouble with one of its four reactor coolant pumps. Jennifer Young, a FirstEnergy spokesman, said the plant automatically shut down after the apparent electrical problem with a motor. There were no injuries. Workers were trying to solve the problem, and Young said she didn't know when the plant would start back up. The Nuclear Regulatory Commission says it is monitoring the situation. Electric customers will see no power interruption. |
Davis-Besse still shut down today
Details emerge about what caused unplanned closure

The Davis-Besse Nuclear Power Station remained shut down Sunday after one of its four reactor coolant pumps experienced trouble.
OAK HARBOR, Ohio — The Davis-Besse Nuclear Power Station remained shut down today as more details emerged about what caused the unplanned closure.
Workers identified a problem with electrical wiring that connects a terminal box to the motor that powers one of the plant’s four reactor coolant pumps, said Jennifer Young, a FirstEnergy spokesman.
The wiring requires repair, and testing of the motor continues, she said. She did not know when the plant would restart or what caused the wiring problem.
“That will be a longer investigation. That’s not an answer that I expect we will have quickly,” she said.
The plant automatically shut down about 9:20 p.m. Saturday. No injuries occurred, and there are no threats to public safety, Ms. Young said.
“We are still able to provide adequate cooling to the reactor,” she said.
Ms. Young said testing of the motor will be completed today, which will allow workers to determine what, if any, additional work is required.
She declined to estimate when the plant could be back in operation, saying the start time is “considered competitive information.”
“It could impact the price of power when any plant is down,” she said. “So that’s why in the competitive marketplace we can’t share estimated … return-to-service dates.”

Workers identified a problem with wiring connected to the motor that powers one of the plant’s four reactor-coolant pumps, said Jennifer Young, a FirstEnergy spokesman. She said she did not know what caused the wiring problem.
“That will be a longer investigation. That’s not an answer that I expect we will have quickly,” she said.
Ms. Young said motor testing took place Monday, which will help determine when the plant will restart.
While inspecting the equipment, Ms. Young said workers found another problem to correct. A weld overlay will fix a flaw on a recirculation line that provides lubrication to the seal on the same pump, she said. The recirculation flaw was not a factor in the shutdown.
