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

Explanation

i. Large amount of energy is generated in a matter of second in a fission reaction . If the fission reaction is not controlled it can prove fatal.
ii. Uncontrolled fission reaction may lead to the emission of harmful radiations.
iii. It can also lead to the meltdown of the nuclear power plant.
Thus, it is absolutely necessary to control the fission reaction in nuclear power plants.
