Question
Which is the process used to harness nuclear energy these days? Explain it briefly.
✓
Answer
Nuclear energy is harnessed in nuclear power plants. It contains a nuclear reactor, a boiler and a turbine.
- The nuclear reactor is the place where nuclear fission is carried out. Nuclear fission produces a huge amount of energy.
- Energy produced during nuclear fission is utilized to boil water, so that steam can be generated.
- Steam is utilized to turn the turbines to produce electricity.
