Template:Infobox Nuclear power plant
The Callaway Nuclear Generating Station is a nuclear power plant located on a 5,228-acre (21 km²) site in Callaway County, Missouri, near Fulton, Missouri. It began operating on December 19, 1984. The plant, which is the state's only commercial nuclear unit, has one 1,190-megawatt Westinghouse four-loop pressurized water reactor and a General Electric turbine-generator. It is fully owned by the Ameren Corporation and operated by AmerenUE.
According to Ameren, Callaway produces about 19 percent of AmerenUE's power.[1] In 2001, Callaway set a plant record for capacity utilization, producing 101.1 percent of its rated electrical output, ranking it among the world's top reactors, according to the Energy Information Administration.[2]
On November 19, 2005, its workers completed the replacement of all four steam generators in 63 days, 13 hours, setting a world record for a four-loop plant.[3]
On July 28, 2008, AmerenUE submitted an application to the U.S. Nuclear Regulatory Commission (NRC), seeking a Combined Construction and Operating License (COL) for a potential second unit. According to Thomas R. Voss, president and chief executive officer of AmerenUE, "Given projections for a nearly 30 percent increase in demand for power in Missouri in the next two decades, we believe we will need to build a large generating plant to be on line in the 2018–2020 timeframe."[1] AmerenUE is considering building a 1,600-MW Areva Evolutionary Power Reactor (EPR).[4]
In April 2009, AmerenUE canceled plans to build a second reactor at its mid-Missouri nuclear power plant. A key stumbling block was a law barring utilities from charging customers the costs of a new power plant before it starts producing electricity. The new nuclear plant would have cost at least $6 billion.[5][6]
