Give scientific reasons:

It is absolutely necessary to control the fission reaction in nuclear power plants.

In nuclear power plants, a controlled chain reaction results in release of thermal energy, which is used for electric energy generation.

If the reactions are not controlled, a huge amount of energy can be generated which can be dangerous as the neutrons generated in the reactions split up producing more atoms via fission.
