Nuclear power plants
A nuclear power plant uses the heat that a nuclear reactor produces to turn water into steam, which then drives turbine generators that generate electricity. U.S. nuclear power plants use two types of nuclear reactors. Nuclear power plants in the United States have either a boiling-water reactor or a pressurized-water reactor.
