The working of a nuclear power plant is as follows:
A controlled chain reaction occurs in a nuclear power plant which produces a lot of heat.
The heat energy released from nuclear fission is utilized by the boiler to generate high-velocity steam, which is used to rotate the turbine blade.
A generator is directly connected to the turbine, which generates electricity from the rotation of the turbine.
On the other hand steam loses its energy and comes to the condenser.
In the condenser, the cold water coming from the cooling tower absorbs the heat and due to condensation steam becomes water and a pump is used to pump it to the boiler again and this process continues.
A cooling tower is used to cool hot water coming from the condenser, and the chimney removes the water vapor and hot air into the atmosphere.
This journey of getting electrical energy from nuclear energy started with a controlled chain reaction of nuclear material.
