Diesel Power Plants Diesel power plants of 2 to 50 MW capacities are used in central power station for peak loads in conjunction with either steam or hydraulic power plants. These plants are also used by industrial undertakings for small power supplies. The plants are also installed at places where fuel costs are low, water … Read more
Comparison between Nuclear and Conventional Thermal Power Plants Advantages of nuclear power plants over thermal power plants : For similar capacity plants, the space required is less. Cost of fuel transportation, storage and handling is very less since nuclear fuel requirements is much less compared to coal. It is more economical to operate, particularly in … Read more
Nuclear Waste Disposal Waste disposal of nuclear power station is of prime importance since the nuclear waste is likely to have radioactivity. Therefore, these wastes are disposed off in such a manner that it does not cause harm to human or plant life. The various methods adopted are : In case of gaseous wastes, it … Read more
Nuclear Power Plants In India Following nuclear power plant stations have been built in India : 1. Tarapur atome power station : This is the India’s first nuclear power station of 380 MW capacity which has been built at Tarapur situated on west coast at a distance of about 100 km from Bombay in collaboration … Read more
Selection of Site for Nuclear Power Plants Various points to be considered in selection of site for nuclear power plants are as follows : Availability of water for steam generation and cooling water for condenser. It should be nearer to sea, river or reservoir. Nearer to load centre to reduce power transmission losses. Away from … Read more
Liquid Metal Fast Breeder Reactors (LMFBR) and its Advantages and Disadvantages When uranium U235 is fissioned by slow neutrons it produces heat and an additional neutron. In case a fertile material like U238 is kept in the same reactor surrounding the core of U235, the fast moving additional neutron is absorbed by U238 and converts it into plutonium … Read more
Liquid Metal Reactor or Sodium Graphite Reactor (SGR) Power Plant and its Advantages and Disadvantages Sodium graphite reactor is a typical liquid metal reactor. The arrangement of a sodium graphite reactor power plant is shown in Figure. It uses graphite as the moderator and liquid sodium as coolant which can reach temperature of about 850°C … Read more
CANDU Reactor Power Plant and its Advantages and Disadvantages A reactor developed and designed by Canadian is called as CANDU (Canadian Deutorium Uranium) reactor. It uses pressurized heavy water (PHW) (which is 99.8% deutorium oxide, D2O) a moderator and primary coolant while the fuel used is natural uranium. A CANDUPHW (Canadian Deutoriam Uranium Pressurized Heavy … Read more
The Gas Cooled Reactors (GCR) and its Advantages and Disadvantages A gas cooled reactor was first developed in U.K. uses CO2, as coolant instead of water and graphite as moderator. It is called gas cooled graphite moderated (GCGM) reactor. It uses natural uranium as fuel. The coolant pressure is about 7 bar and temperature 336°C. … Read more
The Boiling Water Reactor (BWR) Power Plant and its Advantages and Disadvantages The arrangement of a boiling water reactor power plant is shown in Figure. It uses enriched uranium as fuel and water is used both as coolant and moderator. These reactors do not require a heat exchanger as needed in case of pressurized water … Read more
