There are three basic steps in a nuclear fission chain reaction are Initiation, Propagation, Termination.
<h3>
What are the three steps of nuclear fission ?</h3>
1. Initiation
The nuclear fission of 
is started by the absorption of a neutron; a single atom must react in order for the chain reaction to begin.
2. Propagation:-
With each stage producing additional product, this component of the process is repeated repeatedly. When 
splits apart, neutrons are released, which start the nuclear fission of more uranium atoms.
3. Termination:
The chain will come to an end eventually. Termination might take place if the reactant is exhausted or if the subsequent neutrons in the chain leave the sample without being absorbed by .
