The fission reaction must be possible.
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.
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.
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.
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.
What makes a fission reaction possible is that certain atoms, such as uranium and plutonium, are unstable and capable of splitting into smaller atoms when struck by a neutron. This process releases a large amount of energy in the form of heat and additional neutrons, which can go on to trigger more fission reactions in a chain reaction.

The excess of neutrons produced.
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 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

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.
Yes, it is possible to stop a fission reaction at a nuclear power plant by inserting control rods into the reactor core. These control rods absorb the excess neutrons that drive the chain reaction, effectively slowing down and ultimately stopping the fission process.
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.
