Its other units are Curie and Rutherford .
1 Curie = 3.7 * 10 10 decay / s
1 Rutherford = 10 6 decay / s
Nuclear Fission
The process of the splitting of a heavy nucleus into two or more lighter nuclei is called nuclear fission .
When a slow moving neutron strikes with a uranium nucleus
( 92 U 235 ), it splits into 56 Ba 141 and 36 Kr 92 along with three neutrons and a lot of energy .
Nuclear Chain Reaction
If the particle starting the nuclear fission reaction is produced as a product and further take part in the nuclear fission reaction , then a chain of fission reaction started , which is called nuclear chain reaction .
Nuclear chain reaction are of two types
( i ) Controlled chain reaction ( ii ) Uncontrolled chain reaction
Nuclear Reactor
The main parts of a nuclear reactor are following
