Which is the process used to harness nuclear energy these days ? Explain it briefly.

Explanation

Nuclear energy is harnessed in nuclear power plants. It contains a nuclear reactor, a boiler and a turbine. Nuclear energy originates from the splitting of uranium atoms-a process called nuclear fission.
When the reactor starts, uranium atoms will split, releasing neutrons and heat. Those neutrons will hit other uranium atoms causing them to split and continue the process, generating more neutrons and more heat.
This huge amount of energy is utilised to boil water to produce steam which is used by a turbine generator to generate electricity.
Nuclear power plants are different because they do not burn anything to create steam. As a result, unlike other energy sources, they do not release carbon or pollutants like nitrogen and sulphur oxides into the air. So, they do not produce greenhouse gas emissions.
The following figure shows the working of a nuclear power plants.
