How Nuclear Energy Works

Power plants that run on fossil fuels burn coal, oil or natural gas to generate heat. In a nuclear energy plant, heat is produced from splitting atoms - a process called nuclear fission. Nuclear reactor creates heat that is used to make steam. The steam turns a turbine connected to an electromagnet, called a generator.
