Question

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

Answer 1

HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this question.

To make sure they could safely control the chain reaction, they used what they called “control rods.” These were simply sheets of the element cadmium, an excellent neutron absorber. The physicists interspersed control rods through the uranium-graphite pile.

At every step of the process theycalculated the expected neutron emission, and slowly removed a control rod to confirm his expectations. As a safety mechanism, the cadmium control rods could quickly be inserted if something started going wrong, to shut down the chain reaction.

I HOPE IT HELPS U.

Answer 2

If fission reaction in nuclear power plants is not controlled, then enormous amount of heat released during this process will lead to explosion of the plant and cause fatal destruction to environment and mankind. Thus, it is absolutely necessary to control the fission reaction in nuclear power plants.
