The nuclear power plant in central Missouri shut down for the second time in eight months, this time after a “non-emergency” leak in the reaction control system.
The shutdown occurred at 1:15 a.m. Thursday at the plant near Fulton, MO, said officials at Ameren Corp.
Jeff Trammel of St. Louis-based Ameren called it a “minor steam leak.” He said no one was hurt and there was no risk to the public.
Ameren officials are investigating the cause of the leak. Trammel said it remains unclear when the plant will restart.
The U.S. Nuclear Regulatory Commission (NRC) received notification. An NRC report classifies it as a “non-emergency” and said radiation levels in the containment building are “slightly above normal,” but there were no excessive radiation releases from the plant.
The Callaway plant also shut down in December, due to an electrical equipment failure.
