How many nuclear power plants are in the United States, and where are they located?
There are 61 commercially operating nuclear power plants with 99 nuclear reactors in 30 states in the United States. Thirty-five of these plants have two or more reactors. The Palo Verde power plant in Arizona has three reactors and had the largest combined net summer generating capacity of 3,937 megawatts (MW) in 2014. Fort Calhoun in Nebraska with a single reactor had the smallest net summer capacity at 479 megawatts (MW) in 2014.
Three nuclear power plants with a total of four reactors were taken out of service in 2013: the Crystal River power plant in Florida with one reactor in February; the Kewaunee power plant in Wisconsin with one reactor in April; and the San Onofre power plant in California with two reactors in June. The Vermont Yankee nuclear power plant in Vermont, with a single reactor, was taken out of service in December 2014.
