The fact that when a fission occurs, more than one neutron is released. Thus by careful design, one of these second generation neutrons can be captured by a further nucleus causing another fission, and so on.
Up to about 2.5 neutrons per fission can be utilized. In a bomb, all of them are used, and the reactivity (approximately) doubles with each reaction. In a controlled reaction, such as in a reactor, the moderator and geometry are such that one neutron per fission goes on to create another fission, yielding a stable reactivity.
The property of releasing additional neutrons during the fission process leads to the possibility of a chain reaction. When these neutrons go on to cause more fission events, it creates a self-sustaining chain reaction that can release a large amount of energy.
nuclear fission is useful for:
The release of heat in fission enables it to produce useful electric power, using the normal steam cycle.
It does not produce combustion gases like fossil fuels do
The amount of energy produced by a fission reaction can be used to produce a high amount energy that can be converted into electricity.
Energy production is one of the benefits.
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.
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.
Nuclear fission is the term that describes the reaction process in which the nucleus of an atom is split into two or more smaller nuclei, releasing a large amount of energy.

A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
The first time a fission chain reaction was produced was in 1942
Nuclear fission is the term that describes the reaction process in which the nucleus of an atom is split into two or more smaller nuclei, releasing a large amount of energy.
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.
Fissile, that is they will split on capturing a neutron, releasing energy. Also if the fission releases more neutrons, as with U-235 and Pu-239, this gives the possibility of a chain reaction.
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.
A nuclear fission reaction occurs in a nuclear power plant. This is the process where the nucleus of an atom is split, releasing large amounts of energy in the form of heat, which is used to generate electricity.
Not of itself, but it can be made to be.
Neutrons released during a fission reaction trigger other fission reactions.
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.
A nuclear chain reaction nuclear fission
further fission reactions, leading to a chain reaction. This process releases more neutrons, producing a large amount of energy. Controlling the rate of the chain reaction is crucial for nuclear power generation and atomic weapons.
