Reactor is that part of nuclear power plant where nuclear fuel is subjected to nuclear fission and the energy released in the process is utilised to heat the coolant which may in turn generate steam or be used in a gas turbine. The main function of the reactor is to control the emission and absorption of neutrons. A nuclear reactor [...]
In this article we will discuss about the classification and safety of nuclear reactors. Classification of Nuclear Reactors: Nuclear reactors may be classified in several ways i.e., on basis of their applications, type of fission, fuel used, state of fuel, fuel cycle, arrangement of fissile and fertile material, arrangement of fuel and moderator, moderator material, cooling system employed, coolant used [...]
