⚛ Nuclear Power Plants in South Carolina
South Carolina operates 4 nuclear power plants totaling 6,875 MW of nameplate capacity. Annual generation: 55.6M MWh.
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.
