A fission reaction is initiated by bombarding a heavy atomic nucleus, like uranium or plutonium, with a neutron. This causes the nucleus to split into two smaller nuclei, releasing more neutrons and a large amount of energy. To sustain the reaction, these released neutrons must continue to collide with other nuclei, causing them to split and release more neutrons, creating a chain reaction. This process is carefully controlled in nuclear reactors to generate heat for electricity production.

How is nuclear fission initiated in a nuclear reactor?
Nuclear fission in a nuclear reactor is initiated by bombarding uranium or plutonium atoms with neutrons, causing them to split and release more neutrons, which then continue the chain reaction.
For a sustainable fission reaction each fission must produce exactly additional fission reaction(s).?
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
What does a fission reaction require to be sustainable?
A sustained fission reaction requires a critical mass of fissile material, such as uranium-235 or plutonium-239, and a moderator to slow down the emitted neutrons, like water or graphite. Additionally, a fission chain reaction needs a controlled environment in which the reaction can be regulated to ensure it doesn't run away uncontrollably.
What reaction keeps going on its own once it starts?
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.
For a chain reaction to occur each vision must produce at least more fission reaction Apex?
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.
What part of a fission reaction makes is capable of producing energy from a self sustained chain reaction?
You think probable to neutrons.

Is fusion a chain reaction?
Not exactly, nuclear chain reactions are a series of nuclear fissions initiated by neutrons produced in a preceding fission.

If For a sustainable fission reaction each fission must produce exactly how many additional fission reaction(s).?
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.
How many neutrons are produced during a typical uranium fission reaction and what is the role of these neutrons in a nuclear chain reaction?
A typical uranium fission event produces 2 to 3 neutrons. These neutrons are moderated (slowed down) and go on to initiate the fission of more uranium. On average, in a controlled reaction that is maintained at normal criticality (KEffective = 1), each fission creates exactly one neutron that is used to produce another fission.
What is the smallest amount of radioactive material that will support a self sustained reaction?
The smallest amount of radioactive material that can support a self-sustained nuclear reaction is called the "critical mass." This mass varies depending on the type of fissile material, such as uranium-235 or plutonium-239, and the configuration of the material. For instance, the critical mass for uranium-235 in a spherical shape is about 52 kilograms. This threshold is crucial for achieving a sustained chain reaction in nuclear fission.
When was fission reaction invented?
The first time a fission chain reaction was produced was in 1942
Why does only one neutron need to be fired to react all of the uranium 235 atoms?
For each nuclear fission are released approx. 2,5 neutrons and a nuclear chain reaction is initiated.
For a chain reaction to occur each vision must produce at least more fission reaction Apex?
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.
