What do you mean by the chain reaction in nuclear fission? How is it controlled?

Solution:

A chain reaction is a process in which a neutron released in fission causes another fission in at least one more nucleus. It generates a massive amount of energy.

The chain reaction is regulated by absorbing part of the neutrons emitted during the fission process. It is done by cadmium rods and then slowing them down with moderators like graphite, heavy water, and so on. The energy gained during fission can then be used constructively.
