The excess of neutrons produced.
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.
The first time a fission chain reaction was produced was in 1942
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
In a chain reaction, each fission reaction must produce at least one additional fission reaction to sustain the reaction. This is necessary to achieve a self-sustaining nuclear reaction where each fission event leads to more fission events, releasing energy in the process. Without this multiplication of fission reactions, the chain reaction would not be able to continue and sustain itself.
It is called nuclear chain fission reaction.
To sustain a fission chain reaction, each fission reaction must result in one more fission reaction. And that one should result in one more, and so on.
Not of itself, but it can be made to be.
For a chain reaction to occur, each fission must produce at least one more fission reaction. This leads to a self-sustaining reaction where each fission event triggers more fission events, resulting in a continuous release of energy.
This process is called a nuclear chain reaction. Neutrons released from one fission event trigger other fission events, creating a self-sustaining reaction that releases energy and more neutrons, continuing the chain reaction.
Neutrons released during a fission reaction trigger other fission reactions.
another name for nuclear fission is: E=MC squared
Fission and fusion reactions are chain reactions but in different ways. In fission reaction a heavy nuclei is bombarded with a slow moving neutron and this nuclei breaks to produce more such neurons along with generation of new elements. These slow moving neutrons are further used to carry out fission of more such nuclei. This is chain reaction. Fusion reaction are a different class of nuclear reaction in which small nuclei fuse together to produce bigger nuclei along with the generation of energy due to mass defect.. In fusion reaction lot of energy is produced and this energy is used to carry out further reaction. Thus both can be called series reaction.
