Nuclear scientist Interview Question:

Explain what Is Chain Reaction And How It Is Controlled In Nuclear Reactor?

Submitted by: Muhammad

In fission reaction during every stage two or more daughter nuclei is released, two or more neutrons and vast energy is released. Each neuron produced further participate in fission reaction and results in release of more neutrons, this reaction continues results in nuclear explosion. However in nuclear reactor the excess neutrons produced will be absorbed using moderator and control rods allowing only one neutron per fission to carryout further chain reaction.
