Lacey, NJ-based Oyster Creek Generating Station shut down automatically at 3:42 a.m. Sunday, due to a fault in the nuclear power plant’s turbine control system, said officials at its parent company Exelon Corp.
The system controls turbine conditions and speed, and is on the non-nuclear side of the plant, according to Exelon.
Technicians worked Sunday to repair and test the system before returning it to service.
“The plant responded as expected, safely and without incident,” Exelon officials said. “The Oyster Creek shutdown will not have an impact on electrical service to Exelon customers.”
Oyster Creek is the oldest operating nuclear power plant in the United States. It is on schedule to shut down in 2019.
