Nuclear power station :
In the nuclear power station, energy is produced by nuclear fission of Uranium (U235),
Thorium (Th232), Plutonium (Pu239). The fission process takes place in a nuclear
reactor and material in certain circumstances can be made to become unstable and
transform themselves into ordinary chemical elements, iron nickel, silicon and
calcium and in this process set free a considerable amount of heat energy. Heat thus
generated will be taken away by fluid such as molten bismuth or liquid sodium. This
hot molten metal will convert feed water into high-pressure steam in a heat exchanger.
The steam thus generated is utilized to drive steam turbine coupled to an alternator
and exciter, thereby generating electrical energy.
Low temperature and low pressure steam from turbine is condensed in a condenser
with the help of circulated cooling water. From the condenser, water is again fed to
heat exchanger with the help of a feed water pump for converting it into steam.
In this power station transportation of fuel is not a problem, because one kg of atomic
fuel can generate as much electrical energy as can be generated from about
2500 tonnes of high grade coal.
The most suitable areas in our country for atomic power stations are western UP,
Rajasthan, Punjab and Haryana
Few examples of atomic or nuclear power stations are as follows:
1. Tarapur Atomic Power Stations, Tarapur near Mumbai.
2. Ranapratap Atomic Power Stations, Kota (Rajasthan).
3. Madras Atomic Power Stations, Kalpakkam (Tamil Nadu).
