Breeder reactor is the one which converts non-fissionable material (U238) into fissionable material (U235). or A nuclear reactor that produces (breeds) some kind of fissile material as it burns is called breeder reactor. These...

Most commercial nuclear power plants today are light water reactor. U-235 fuel rods are submerged in water, where the water acts as a coolant as well as a moderator. This is called a light water power plant. The fission reaction...
Components of a nuclear reactor and its functions Controlled fission reaction is carried out in a specially designed plant called nuclear reactor or nuclear power plant. Nuclear reactor consists of: Reactor core Fuel...
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...
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 the fission of U235 92U235 + 0n1 →...
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...
In a nuclear fusion two light-weight nuclei combine or fuse to form a single heavy nucleus., with the simultaneous release of large amount of energy. For example, two nuclei of deuterium undergo fusion reaction to yield a heavy...
In many cases corrosion can be effectively controlled by changing or modifying the corrosive environment by: The corrosion nature is reduced by modifying the environment: the removal of harmful constituents in the environment...
The rate and extent of corrosion depends on: Nature of the environment Nature of the metal. S.No Environment based factors Metal based factors 1 Temperature. Position of metal in galvanic series. 2 Humidity. Relative...
There are two types of electrochemical Corrosion: Galvanic corrosion Differential aeration or Concentration cell corrosion Galvanic corrosion When two dissimilar metals are in contact with each other on the presence of aqueous...
