Beaver Valley Power Station in the process of starting up after a scheduled refueling shutdown, ended up shut down again by the control room because of a vibration issue.

The control room at FirstEnergy’s nuclear power plant in Shippingport, PA, forced the reactor down Tuesday morning.

The Nuclear Regulatory Commission (NRC) said workers at Beaver Valley Power Station safely shut down unit 2 at 8:35 a.m. because a pump was vibrating. The unit was operating at about 15 percent power as it restarted and workers prepared to reconnect to the grid.

FirstEnergy spokeswoman Jennifer Young said workers found no problems and resumed the restart process, which usually takes several days.

“We encourage our operators to be very conservative,” she said. “We’re very deliberate when we start up. That’s exactly what happened this morning.”

An agency inspector went to the control room and the commission said the shut-down of the 900-megawatt reactor appeared to be appropriate.
