It doesn't always but it does most of the time and this is because the process is started by firing a particle at the nulcleii of a large atom and if it hits and breaks up the nucleus it hits a new particle is fired from this nucleus to hit another one, thus creating a chain reaction.

How is hydrogen used in nuclear fission?
Hydrogen is used in nuclear fission as a moderator to slow down neutrons produced during the fission process, making them more likely to interact with other fissile nuclei to sustain the chain reaction. Water containing hydrogen atoms, such as heavy water (deuterium oxide) or light water (H2O), is commonly used as a moderator in nuclear reactors.
What happens during nuclear fusion and fission?
In nuclear fusion, two atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This is the process that powers the sun and other stars. In nuclear fission, a heavy nucleus splits into two or more lighter nuclei, along with the release of energy and neutrons. This process is used in nuclear power plants to generate electricity.
Is implosion possible and what are the examples of it?
Yes,. One well known example is the atomic bomb dropped on Nagasaki, Japan. The explosives in the bomb were placed around the plutonium then exploded to compress the plutonium to the point where nuclear fission started.
What are the safety precautions for nuclear fission?
Safety precautions for nuclear fission include having redundant safety systems, regular inspections and maintenance, strict adherence to operating procedures, and proper training for personnel. Emergency response plans and drills should also be in place to address any potential incidents.
Does the sun and stars generate energy through nuclear fission reactions?
Stars work on nuclear fusion not fission. When enough material accretes, gravity compresses and heats the material to begin stellar formation. At some point, with enough material and heat, fusion will begin.
What starts the nuclear chain reaction in a nuclear reactor?
The nuclear chain reaction in a nuclear reactor is started by the splitting of uranium atoms, a process known as nuclear fission.
How is hydrogen used in nuclear fission?
Hydrogen is used in nuclear fission as a moderator to slow down neutrons produced during the fission process, making them more likely to interact with other fissile nuclei to sustain the chain reaction. Water containing hydrogen atoms, such as heavy water (deuterium oxide) or light water (H2O), is commonly used as a moderator in nuclear reactors.
What have chain reactions got to do with nuclear fission?
The fission process in a nuclear reactor which produces the thermal energy used in the steam cycle, is called a chain reaction because nuclei of U-235 and Pu-239 fission on absorbing a neutron, and the fission causes further neutrons to be released, thus a self sustaining reaction is started which is controlled to run at a steady power level.
What causes the nuclear reaction to keep going once it has started?
The nuclear reaction in nuclear power plants continues because of a self-sustaining chain reaction. In this process, neutrons produced by fission cause further fission in other uranium or plutonium nuclei, releasing more energy and more neutrons. This chain reaction is controlled and moderated by control rods to maintain a stable and controlled release of energy.
What is fission made from?
Nuclear fission occurs in a few elements and then only in certain isotopes, best known are uranium-235 and plutonium-239. In these cases capture of a neutron causes the nucleus to split up into two lighter pieces, and for neutrons to be emitted. This enables a chain reaction to be started.

In nuclear fission, a heavy nucleus splits into two or more lighter nuclei, along with the release of energy and neutrons. This process is used in nuclear power plants to generate electricity.
How can nuclear fission be forced to happen?
by a neutron source. nuclear reactors are always started with one to avoid a supercritical power surge from damaging the reactor. nuclear bombs are always triggered by one to make sure the reaction happens at optimal supercriticality for desired yield.
Detonation of a fusion type hydrogen bomb is started by?
Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.
What type of nuclear reaction is used n power plants?
Most nuclear power stations have pressurized water thermonuclear reactors. The nuclear reactions that take place in these reactors are fission (atom splitting) and nuclear decay. (Let's not split hairs so we can concentrate on splitting atoms.) In simple terms, these reactors work by fission of enriched uranium, which is uranium with a higher-than-natural amount of the U235 isotope. This isotope has a higher probability of capturing a neutron and splitting than other stuff. That's the fission part. After the uranium splits, neutrons are released and these can be used to make more fissions if they are slowed (thermalized). Links to Wikipedia are provided. There must be some consideration given to the fission products. These are the "broken pieces" left after an atom splits. There are a fair number of these and they continue to decay. Their half lives and decay schemes vary, and an interested party would review the Wikipedia article to get the low down on them. A link is provided.
What happens to nuclear energy before it is used?
Nuclear energy is released as heat in the fuel of a nuclear reactor, but only when the reactor has been brought to criticality and the chain reaction started. At that point the heat must be used, it can't be stored and used later. Before criticality is established, the reactor is shutdown and producing no nuclear heat from fission, so you could regard it as having potential nuclear energy in that state
