Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch.Frisch named the process by analogy with biological fission of living cells.uclear fission produces energy for nuclear power and drives the explosion of nuclear weapons. Both uses are possible because certain substances called nuclear fuels undergo fission when struck by fission neutrons, and in turn emit neutrons when they break apart.
Nuclear power plants use nuclear fission to generate power. The nuclei of uranium atoms, as well as the nuclei of other large atoms, can undergo nuclear fission naturally. The first nuclear fission reaction discovered involved uranium-235. Nuclear power plants use uranium-235 nucleus to undergo fission by hitting them with neutrons, as shown by the model in the following diagram. The figure represents the process of nuclear fission when a neutron strikes a uranium-235 nucleus.
