India’s uranium supply comes from jadugada mines of Bihar. Heavy water is prepared in heavy water plant at Nangal, kota, Vadodra and Talchar.
- Boron rod called the control rod because they absorbed the excess neutrons and prevents the fission reaction from out of control.
- Graphite or heavy water is called a moderator. It slows down the speed of neutrons.
Nuclear chain reaction
In this particle that initiate the reaction is also produced during the reaction and it carries the reaction further and further. Such as fission of uranium-235.
This is called uncontrolled nuclear reaction. It is the basis of Atomic Bomb. Energy released in nuclear fusion is more than that released in nuclear fission and it does not pollution problem.
