Ameren’s Callaway County nuclear plant will remain shut down for several days as workers from the electric utility perform tests and repair damage after a small fire Friday night.
Crews are taking apart and checking electrical equipment in the area of the fire, which was in the “non-nuclear” power-generation side of the facility, and that the plant would remain offline until their work is through, said Cleveland Reasoner, vice president of engineering for Ameren.
“We can’t discuss exact timelines but it will be several days,” Reasoner said.
The Callaway County reactor supplies about 20 percent of the electricity used by Ameren Missouri’s 1.2 million customers. Other Ameren plants will make up for the lost power generation while the nuclear plant is offline
The fire occurred shortly before midnight Friday and the plant fire crew put it out quickly. Power cables that connect the plant to the electric grid shorted, causing some nearby insulation to catch fire, Reasoner said. The nuclear reactor automatically shut down and no radioactivity released, Ameren said.
The company is working with the U.S. Nuclear Regulatory Commission on the assessments.
