After a manual shutdown, the Oyster Creek Generating Station’s nuclear reactor remains offline following an increase in pressure in the reactor.

The Nuclear Regulatory Commission (NRC) said the plant, located in Lacey Township, Ocean County, near the New Jersey Shore, is not getting power at this time.

A spokesman for the NRC said the plant’s control room operators manually shut down the reactor on Saturday in response to increasing reactor pressure.

“Cool down was achieved using the plant’s isolation condensers,” said Neil Sheehan, NRC spokesman.

At the time of the shutdown, plant workers were conducting turbine valve testing. They have not determined the cause of the problem involving the turbine control system, Sheehan said.

One of the NRC resident inspectors assigned to Oyster Creek on a full-time basis responded to the site following the shutdown to independently verify that the plant was in a safe condition and that the operators were taking the appropriate actions, Sheehan said.

“The inspector did not identify any significant concerns with the [shutdown] or with subsequent operator actions to stabilize the plant,” Sheehan said.

Suzanne D’Ambrosio, plant spokeswoman, said staff will take advantage of the outage to perform additional maintenance work to “keep the unit operating reliably and efficiently.”
There has not yet been a determination as to when the plant will return to service.
