The path to nuclear fission
WebbOne of these neutrons must trigger another fission for a sustained chain reaction. The fission reactions in a nuclear reactor can be written generically as follows: U-235 + n ==> U-236. U-236 ===> fission fragments + 2 to 4 neutrons + 200 MeV energy (approx.) The uranium-236 nucleus does not split evenly into equal fission fragments. WebbNuclear 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 radioactive decay.. Nuclear fission of heavy elements was discovered on Monday 19 December 1938 in Berlin, by …
