Nuclear engineering is the engineering discipline concerned with designing and applying systems that utilize the energy released by nuclear processes.
The most prominent application of nuclear engineering is the generation of electricity. Worldwide, some 440 nuclear reactors in
32 countries generate 10 percent of the world's energy through
nuclear fission
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactiv ...

In the future, it is expected that
nuclear fusion
Nuclear fusion is a nuclear reaction, reaction in which two or more atomic nuclei combine to form a larger nuclei, nuclei/neutrons, neutron by-products. The difference in mass between the reactants and products is manifested as either the rele ...
will add another nuclear means of generating energy. Both reactions make use of the
nuclear binding energy released when atomic
nucleons are either separated (fission) or brought together (fusion). The energy available is given by the
binding energy curve, and the amount generated is much greater than that generated through chemical reactions. Fission of 1 gram of uranium yields as much energy as burning 3 tons of coal or 600 gallons of fuel oil, without adding carbon dioxide to the atmosphere.
History
Nuclear engineering was born in 1938, with the discovery of nuclear fission. The first ''artificial'' nuclear reactor,
CP-1, was designed by a team of physicists who were concerned that

might also be seeking to build a bomb based on nuclear fission. (The earliest known nuclear reaction on Earth occurred
naturally, 1.7 billion years ago, in Oklo, Gabon, Africa.) The second artificial nuclear reactor, the
X-10 Graphite Reactor, was also a part of the
Manhattan Project, as were the
plutonium-producing reactors of the
Hanford Engineer Works.
The first nuclear reactor to generate electricity was
Experimental Breeder Reactor I (EBR-I), which did so near
Arco, Idaho, in 1951.
EBR-I was a standalone facility, not connected to a grid, but a later Idaho research reactor in the
BORAX series did briefly supply power to the town of Arco in 1955.
The first commercial nuclear power plant, built to be connected to an electrical grid, is the
Obninsk Nuclear Power Plant, which began operation in 1954. The second is the
Shippingport Atomic Power Station, which produced electricity in 1957.
