NUCLEAR CHAIN REACTION
We have already discussed that when a slow moving neutron hits a nucleus of U-235, three neutrons are produced. These three neutrons can strike with three more nuclei of U-235 to produce 9 neutrons, which in turn can bring about fission of nine nuclei of U-235 to produce 27 neutrons and so on. Thus, a continuous chain of nuclear reactions called nuclear chain reaction will be set up which will lead to production of a large amount of energy. If this reaction is allowed to continue endlessly, a very large amount of energy will be produced in a very short time which will lead to explosion. That is why; this reaction is used to make highly destructible atom bombs. This reaction can be represented as:
