Question

what is the three general steps in nuclear chain reaction ?

Answer 1

answer :-


A nuclear fission chain reaction has three genral steps :


1 :) Initiation :-


the reaction of a single atom is needed to start the chain reaction fission of 92U^235 is intiated by the absorption of a neutron.


2 :) Propagation :-

this part of the process repeats itself over and over , with each step yielding more product . the fission of 92U ^236 releases neutrons that initiate the fission of other uranium atoms.


3 :) Termination :-

Eventually , the chain will end . termination could occur if the reactant ( 92 U 235) is used up , or if the neutrons that continue the chain escape from the sample without being captured by 92U235.


mark me as brain list

Answer 2

hey mate ,

here is your answer :)

==============

A chemical chain reaction proceeds by a sequence generally subdivided into three stages

• Initiation,
• Propagation
• Termination

(1) Initiation,

in which a reactive intermediate, which may be an atom, an ion, or a neutral molecular fragment, is formed, usually through the action of an agent such as light, heat, or a catalyst.

(2) Propagation,

whereby the intermediate reacts with the original reactants, producing stable products and another intermediate, whether of the same or different kind; the new intermediate reacts as before, so a repetitive cycle begins.

(3) Termination,

which may be natural, as when all the reactants have been consumed or the containing vessel causes the chain carriers to recombine as fast as they are formed, but more often is induced intentionally by introduction of substances called inhibitors or antioxidants.
