Question

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

Answer 1

Explanation:

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.

Answer 2

Answer:

Solution

(1) Nuclear fission reaction is a type of chain reaction. In nuclear power plants these reactions are closely controlled. (2) If these reactions are not managed properly, there can be more production of neutrons in an uncontrolled way. (3) Each neutron further causes fission of 3 uranium (u-235) atoms. (4) Such and more energy uncontrolled reactions can cause hazardous accidents, hence it is absolutely necessary to control the fission reaction in nuclear power plants.
