The Callaway Energy Center near Fulton remains closed after a small fire in the turbine building.
Ameren Missouri says that workers have been performing tests and repairing damage from a small fire Friday night. The fire was in the "non-nuclear" power-generation side of the Callaway County nuclear facility. An Ameren spokesman says cables that connect the plant to the electric grid shorted, causing nearby insulation to catch fire.
An earlier press release said the center is "out of service in accordance with safety protocols and procedures."
KBIA spoke to an Ameren spokesperson Monday morning, who said repairs at the plant were ongoing. There was no estimate as to when the plant will come back online.
