单词 nuclear energy
释义 nuclear energy
Energy obtained as a result of nuclear fission or nuclear fusion. The nuclear fission of one uranium atom yields about 3.2 × 10-11 joule, whereas the combustion of one carbon atom yields about 6.4 × 10-19 joule. Mass for mass, uranium yields about 2 500 000 times more energy by fission than carbon does by combustion. The nuclear fusion of deuterium to form helium releases about 400 times as much energy as the fission of uranium (on a mass basis)
