A chain reaction is a type of reaction that keeps going on its own once it starts due to the products of the reaction continuing to fuel the reaction. Nuclear fission reactions in nuclear power plants and explosions are examples of chain reactions that continue on their own once initiated.
A stable nuclear fission reaction will be sustained if every fission produces one additional fission 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.
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.
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.

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.
When the powder is ignited, it starts a chemical reaction which creates gases. As these gases expand, the pressure separates the bullet from the casing, and propels the bullet down the barrel.
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
It used 2 pieces of 93.5% enriched Uranium-235: the target and the bullet at opposite ends of a cannon barrel. Cordite propelled the bullet down the barrel to the target. Once at the target, creating a supercritical mass, the bullet crushed the neutron source which generated a pulse of neutrons (about 10 in the time to set off the bomb).For more details see The Making of the Atomic Bomb by Richard Rhodes.
The first time a fission chain reaction was produced was in 1942

Yes, a chain reaction is all fission, just out-of-control fission. Usually, fission creates 2 neutrons per decay, but it is controlled by the fact that lots of neutrons get absorbed by U-238, which doesn't fission, unlike U-235, which does, and by the control rods, which also absorb lots of neutrons. But if these fail to contain the outbreak of neutrons, and the fail safes (which usually just drop the control rods totally into the reactor, stopping any chain reaction) fail, then an exponentially accelerating chain fission reaction can start, and once it starts, it's pretty much impossible to stop.
