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

Nuclear Power - A Short HistoryNuclear fission is the splitting of the nuclei of (normally) very heavy or unstable elements (normally heavier than iron), resulting in a release of large amounts of energy as well as the unstable, hot isotopes of lighter elements, as well as some(prenominal) logical image of neutrons. For atomic number 92 235, the most abundant operable 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 efficiently win 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 t he subject of a chain-reaction of radioactive isotopes in 1933 (Szilrd, two hundred6) he patented his idea in 1936 in the U.K., and shared a patent with Enrico Fermi in the United evidences. 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 rise of a few smaller atoms in addition to neutrons and energy Mietner and Frisch interpret 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). In 1942 and after deciding that ura... ...n the Accident at Three Mile Island.
