Classification of a nuclear reactor A. Classification by type of nuclear reaction: → Thermal reactors: They use slow or thermal neutrons. Almost all current reactors are of this type. These contain neutron moderator materials that slow neutrons until their neutron temperature is thermalised. → Fast neutrons: They use fast neutrons to cause fission in their

[/sc_fs_faq] The fission of U235 or Pu239 occurs instantaneously producing large amount of energy in the form of heat and radiation. Calculation of energy released due to nuclear fission Consider

Nuclear chain reaction is defined as a fission reaction where the neutrons from a previous step continue to propagate and repeat the reaction. We know that U235 when bombarded hit by a neutron undergoes the following fission reaction: 92U235 + 0n1 → 56Ba140 + 36Kr93 + 30n1 + Energy In this reaction three neutrons are produced. These
