Home › Nuclear Power Plants in America Nuclear Power Plants in America The United States operates 62 nuclear power plants with a combined nameplate capacity of 103,823 MW .
Nuclear plants generate carbon-free baseload electricity by fissioning uranium fuel inside a reactor. They run nearly around-the-clock — typical capacity factors above 90% — and a single facility can power millions of homes. Spent fuel is stored on-site in dry casks. NRC oversees safety; emergency planning zones extend 10 miles from the reactor.
The table below lists the 100 largest nuclear plants ranked by capacity. For the complete fuel-type breakdown, visit the Nuclear fuel page . To find nuclear plants near your address, try Nuclear power plants near me .
