What is Chain Reaction?

A Chain Reaction happens when neutrons created by the fission of one atomic nucleus trigger further fissions, resulting in a self-sustaining series of processes.

Types of Chain Reaction

There are two types of this reaction โ€“

  1. Controlled Chain Reaction: It is carefully controlled to generate a continuous energy release, similar to a nuclear reactor.
  2. Uncontrolled Chain Reaction: It is happens quickly and releases energy explosively, much like a nuclear bomb.

Mechanism of Chain Reaction

This is the mechanism of this process โ€“

  • Neutrons are released during fission, and these particles have the ability to trigger more fissions.
  • Reactor control rods can be used to absorb some of the neutrons in order to regulate the reaction.
