  1. Sources of Energy Nuclear Power Plant The most important use of nuclear energy (or atomic energy) is the generation of electricity. This is done by using a set-up called nuclear power plant.

  2. Sources of Energy Nuclear Power Plant Nuclear power plant and its work The heat produced in a controlled fission can be used for producing electricity. The setup used for generating electricity from the heat released in a controlled nuclear fission is called a nuclear power plant or nuclear power station.

  3. Sources of Energy Nuclear Power Plant Principle of nuclear power plant:The heat produced in a controlled nuclear fission is used for producing steam. The steam so produced runs the turbine. The rotatory motion of the turbine rotates the alternator of the generator and the electricity is produced. Thus, in a nuclear power plant the energy transforms in the following sequence.

  4. Sources of Energy Components of Nuclear Power plant A nuclear power plant consists of the following components Nuclear reactor: Here, a controlled nuclear fission of a fissionable fuel such as 235 U 92 is carried out. (b) Heat exchanger: The reactor is connected to a heat exchanger. Here, the heat produced in the reactor is transferred to water by circulating a coolant through a coiled pipe. The water gets converted into steam. The coolant is pumped back to the reactor.

  5. Sources of Energy Components of Nuclear Power plant (c) Steam turbine: The steam generated in the heat exchanger is used to run the steam turbine. The spent steam is sent back as hot water to the heat exchanger. (d) Electric generator (or dynamo): The shaft of the steam turbine is connected to an electric generator (or dynamo). Electricity so produced is sent for transmission.

  6. Sources of Energy Atomic Power Stations At present about 3% of the electrical energy produced in India is obtained from nuclear power stations (also called atomic power stations). The name of some atomic stations are operated in India: Tarapur atomic power station (420 MW) in Maharashtra. (ii) Rajasthan atomic power station (440 MW) at Rana Pratap Sagar near Kota in Rajasthan.

  7. Sources of Energy Atomic Power Stations (iii) Madras atomic power station (420 MW) at Kalpakkam in Tamil Nadu. (iv) Narora atomic power station (470 MW) near Bulandshaharin Uttar Pradesh
