Nuclear power plant
Selection of site for Nuclear Power Plant
The following points should be kept in view while selecting the site for a nuclear power station (i)Availabilty of Water As sufficient of water is required for the cooling purposes,therefore the plant site should be located where ample quantity of water is available. (ii) Disposal of Waste The waste produced by fission in nuclear power staiton is generally radio active which must be disposed off properly to avoid health hazards.The waste should either be burried in a deep trunch or disposed off in a sea quite away from the sea shore.Therefore the site selected for such a plant should have adequate arrangement for the disposal of radio active waste. (iii)Distance from populated areas The site selected for a nuclear power station should be quite away from the populated areas as there is read more

Schematic Arrangement of Nuclear Power Plant
The schematic arrangement of a nuclear power station is shown below. The whole arrangement can be divided into following main stages. (i)Nuclear Reactor (ii)Heat Exchanger (iii)Steam Turbine (iv)Alternator (i)Nuclear Reactor It is an apparatus in which nuclear fuel(U235)is subjected to nuclear fission.It controls the chain reaction that starts once the fusion is done.If the chain reaction is not controlled,the result will be an explosion due to the fast increase in the energy released. A nuclear reactor is a cylindrical stout pressure vessel and houses fuel rods of Uranium moderator and control rods.The fuel rods constitute the fission materials and release huge amount of energy when bombarded with slow moving neutrons.The moderator consists of graphite read more
