How much electricity does a typical nuclear power plant generate?
In 2012, the "average" nuclear power plant in the United States generated about 11.8 billion kilowatt-hours (kWh). There were 65 nuclear power plants with 104 operating nuclear reactors that generated a total of 769 billion kilowatt-hours (kWh), or 19% of the nation's electricity.
Thirty-six of those plants have two or more reactors. The Palo Verde plant in Arizona has three reactors with the largest combined generating capacity1 of about 3,937 megawatts (MW). Fort Calhoun in Nebraska had the smallest capacity with a single reactor at 502 megawatts (MW).
The average plant capacity factor was about 86% in 2012.
