Liquid Metal Cooled Reactor (LMCR) – Working, Advantages & Disadvantages: A liquid metal cooled reactor (LMCR) is an advanced type of nuclear reactor that uses a liquid metal as the primary coolant. The use of liquid metal has many advantages because the reactor need not to be kept under pressure and they allow high power […]

Fast Breeder Reactor (FBR) – Definition and Working Principle: Breeding – The process of producing fissionable material from a fertile material such as Uranium 238 (U238) and thorium 232 (Th232) by neutron absorption is known as breeding. The fast breeder reactor system is shown in Fig. 3.11. Pu239 and U233 are fissionable materials and can be

Canada Deuterium Uranium Reactor (CANDU): It is a Canadian invented pressurized heavy water reactor which uses 99.8 percent of Deuterium oxide D2O (Heavy water) as moderator and coolant. The reactor uses 0.7% U235 (natural uranium) as its fuel. The Canada Deuterium Uranium Reactor consists of a steel cylinder with a horizontal axis containing number of

Pressurized Water Reactor (PWR) – Working Principle: Pressurized Water Reactor uses enriched U as fuel. In this reactor, water is used as coolant and moderator. The water passes through the reactor core and becomes hot water. The hot water flows to a heat exchanger (steam generator) where its heat is transferred to the feed water

Boiling Water Reactor (BWR) – Advantages and Disadvantages: In this Boiling Water reactor, enriched Uranium is used as fuel. Enriched uranium contains more fissionable isotope U235. Water is used as coolant, moderator and reflector like in PWR except the steam is generated in the reactor itself instead of separate steam boiler. Water enters the reactor

Nuclear Reactor – Definition and its Components: Nuclear reactor is an apparatus which is used to extract the heat produced by the nuclear fission chain reaction. In other words, a nuclear reactor is a controlled chain-reacting system supplying nuclear energy. Mechanism of heat production The fission fragment after bombardment with the nucleus move at high

Nuclear Fission and Nuclear chain reaction: Uranium exists in different isotopes of U238, U234 , and U235. Out of these, U235 is the most unstable. When unstable heavy nucleus is bombarded with high energy neutrons, it splits up roughly into two equal fragments and about 2.5 neutrons are released and a large amount of energy is produced
