Nuclear Power - A Short History Essay -- Nuclear Energy Breeder Fissio

Nuclear Power - A Short HistoryNuclear fission is the splitting of the nuclei of (normally) genuinely heavy or unstable elements (normally heavier than iron), resulting in a release of large amounts of energy as salutary as the unstable, radioactive isotopes of lighter elements, as well as any logical number of neutrons. For uranium 235, the most abundant usable fuel present in nature, the number of neutrons released is or so 2.4 per atom, and the energy released is about 215 MeV per atom (Example, nd), or about215 MeV * 6.02*1023 235U * 1000 g * joule235U 1 * g * Kg * MeV * 1.602*10-13= 8.05*1015 joule or 8.05 petajoule per kilogram of uranium 235However, uranium is not found in natural concentrations of more than 0.7% of any given amount of uranium in order to expeditiously obtain energy from uranium, one must enrich the uranium, or concentrate the usable isotopes (Uranium, nd).Leo Szilard, a Hungarian scientist who had recently escaped Berlin for London, first entertain the id ea of a chain-reaction of radioactive isotopes in 1933 (Szilrd, 2006) he patented his idea in 1936 in the U.K., and shared a patent with Enrico Fermi in the united States. Later, Otto Hahn and Fritz Stressmann, along with Lise Mietner and her nephew Otto Frisch, discovered fission when Hahn and Stressmann bombarded uranium with neutrons, resulting in the emission of a few smaller atoms in addition to neutrons and energy Mietner and Frisch interpreted the resulting energy and atoms as being the results of fission of the uranium atoms nuclei (History, Georgia State University, nd) this fission resulted in huge amounts of energy per reaction (on the order of 200 mega electron-volts per atom of uranium 235).
