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 [...]

Heavy Water Cooled and Moderated (CANDU TYPE) Reactor 5. Liquid Metal Cooled Reactor 6. Fast Breeder Reactor. 1. Boiling Water Reactor (BWR): This is the simplest type of water reactor. It [...]
There are many ways of classifying water or hydraulic turbines, for example, according to the type of flow of water, according to action of water on moving blades, according to head and quantity of water available, after the name of originator and according to the specific speed of the machine. According to the type of flow of water, the water [...]
In this article we will discuss about:- 1. Operation of Steam Turbines 2. Classification of Steam Turbines 3. Compounding. Operation of Steam Turbines: The operation of a steam turbine is based upon the principle that the steam issuing from a small opening attains a high velocity. This velocity attained during the expansion of the steam depends on the initial and [...]
