Energy produced by nuclear fission of heavy atomic nuclei. About one-third of all electric power worldwide now comes from nuclear power plants. The navies of many countries include nuclear-powered warships; almost half of U.S. combat warships are nuclear-powered. Most commercial nuclear reactors are thermal reactors. Two types of light-water reactors in use throughout the world are the boiling-water reactor and the pressurized-water reactor. In the liquid-metal fast-breeder reactor, fuel is utilized 60 times more effectively than in light-water reactors. See also nuclear energy
