nuclear energy

Physics

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).

Chemical Engineering

The energy associated with nuclear reactions. The amount of energy released is considerably greater than that associated with chemical reactions. For example, the amount of energy released from radium, which loses an alpha-particle to form radon, is 4.2×10¹¹ joules per mole of radium. The possibilities of harnessing nuclear energy changes has been known since the time when Rutherford brought about the first transmutation of one element to another. This was accomplished by the action of alpha-particles on nitrogen gas to produce the isotope of oxygen-17.
