Exelon (NYSE:EXC) said March 22 that the Oyster Creek nuclear plant in New Jersey automatically shut down that afternoon because of an electrical issue in a system that controls steam pressure.
All systems operated as designed during the reactor’s shutdown, Exelon said in a news release.
Staff will troubleshoot and make necessary repairs to the pressure control system while the plant is shut down. The plant will return to service after repairs are made and the system is tested.
Oyster Creek is about 60 miles east of Philadelphia in Ocean County, N.J. The plant produces 636 MW (net) at full power, enough electricity to supply 600,000 typical homes.
The boiling water reactor (BWR) was commissioned in 1969, according to GenForum data. The plant will retire by the end of 2019.
