The Callaway Plant is a nuclear power plant located in Callaway County, Missouri. The plant is Missouri's only nuclear power plant and is close to Fulton, Missouri.[2] The 2,767 acres (1,120 ha) site began operations on December 19, 1984. It generates electricity from one 1,190-megawatt Westinghouse four-loop pressurized water reactor and a General Electric turbine-generator. The Ameren Corporation owns and operates the plant through its subsidiary Ameren Missouri. It is one of several Westinghouse reactors designs called the "Standard Nuclear Unit Power Plant System," or SNUPPS.[3]
The plant produces 1,279 electrical megawatts (MWe) of net power.[4] As of 2019, Callaway has completed five "breaker-to-breaker" runs — operating from one refueling to the next without ever being out of service. It is one of only 26 U.S. reactors to achieve such a feat according to Ameren.[5]
