The Perry Nuclear Power Plant shut down Monday after a momentary loss of power.

At about 2 a.m., crews at the Perry, OH, plant were working to switch the power supplies for the feedwater control system from its main source to an alternate source as part of routine maintenance, said FirstEnergy spokeswoman Jennifer Young.

The feedwater system brings water into the reactor and has a few different uses, including keeping the reactor cool.

During this switch, the feedwater system lost power for a few seconds, Young said.

While backup systems automatically kicked on, the water level did drop a few inches during this power interruption. Still, 14 feet of water was above the fuel, she said.

Power to the system ended up restored back to its main source, but workers safely shut the plant down so crews could investigate what caused the power loss.

“It’s not enough to just restore power, we have to determine why it happened,” Young said, who pointed out there was no impact to public health and safety. When the plant will resume operation remains unknown.

According to the U.S. Nuclear Regulatory Commission (NRC) event report, the incident ended up classified as a “non-emergency.” The state of Ohio, Perry Township and the NRC resident inspector received notification of the incident.
