Components of a Nuclear Power Plant :
A nuclear power plant consists of the following components : (a) Nuclear Reactor :
यहाँ, Here, a controlled nuclear fission of a fissionable fuel such as 92235
U is carried out. (b) Heat Exchanger :
The reactor is connected to 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. (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.
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. Location of Power Station in India
At present about 3% of the electrical energy produced in India is obtained from nuclear power stations (also called atomic power stations).
The following atomic stations are in operation in India :
Tarapur atomic power station (420 MW) in maharashtra.
Rajasthan atomic power station (440 MW) at Rana Pratap Sagar near Kota in Rajasthan.
Madras atomic power station (420 MW) at Kalpakkam in Tamil Nadu.
Narora atomic power station (470MW) near Bulandshahar in Uttar Pradesh.
