The fission of uranium 235 gives on average 2.5 neutrons per fission. Now you may think it an odd figure, surely it must be a whole number? But in fact not all U235 nuclei follow the same route, a range of different fission products is formed, and when the yield of fission products is analysed, the graph of yield against atomic weight shows two peaks, one around AW 90 and one around 135, so a range of different elemental nuclei results. As well as the neutrons, there is a gamma ray release from the fission. The fission releases about 200 Mev, of which about 160 goes into the fission fragments, 30 into the gamma ray, and the rest into the neutrons. Therefore most of this energy release goes into the fission fragments which recoil and give up their kinetic energy as heat within the fuel elements. Many of the fission products go through subsequent decay with beta release, and once the reactor has operated for a few days and the population of fission products has settled down, these decays add appreciably to the heat generated, and when the reactor is shutdown for maintenance or refuelling this decay heat has to continue to be removed. Some of the fission products act as strong neutron poisons, so this is another factor that has to be allowed for in designing the fuel cycle.
I should perhaps add that for the nuclear chain reaction to continue at a steady rate, one neutron from each fission has to enter another U235 nucleus, causing another fission, and so on. So the excess neutrons have to be controlled, or the power would go on rising. This can be done with control rods or soluble poisons, to augment the fission product poisoning mentioned. This is more important with new fuel loaded, as the fuel charge is used up the amount of poisoning needed reduces, and eventually if more new fuel is not loaded, the reactor will gradually shut itself down.
There is a good Wikipedia article on 'Nuclear Fission', and if you look at this and follow some of the links you will find out more. One of the articles even has an animated diagram showing the fission process.

∙ 10y agoThe particles given off by nuclear fission are neutronsand fission product atoms.
The fission product atoms are highly radioactive and after they are emitted usually undergo beta and gamma decay, giving off high energy electrons, electron neutrinos, and very high energy photons.

What is induced nuclear fission?
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
Compare and contrast nuclear fission and nuclear fu sion?
Fission is when two particles are split to make energy while fusion combines to particles. The result of fission is usually used up radioactive material while fusion results in helium. Fusion makes more energy than fission
What is the process of the production of lighter nuclei from heavier nuclei called. Nuclear radiation nuclear force fusion or fission?
Nuclear fission
How are elements with atomic masses greater than uranium made?
Elements that have greater atomic masses then uranium are created using nuclear fission.
What products do you gain by nuclear fission?
The products which are created as a result of nuclear fission are Pu-239 and a lot of nuclear waste.
Atomic bombs are the result of what nuclear reaction?
fission and/or fusion

What is a fission nuclear reaction?
The primary result of a fission reaction is the conversion of mass to energy. In fission, the nucleus split, either through radioactive decay or as result of being bombarded by other subatomic particles known as neutrons.

Nuclear fission
How are elements with atomic masses greater than uranium made?
Elements that have greater atomic masses then uranium are created using nuclear fission.
Are ionic bonds hard to break?
Yes, and when they are it will result in a massive release of energy. That is what's happening in nuclear fission and atomic bombs.
What products do you gain by nuclear fission?
The products which are created as a result of nuclear fission are Pu-239 and a lot of nuclear waste.
What is an easy description for fission?
In nuclear fission, a very large nucleus such as a uranium nucleus breaks apart into two smaller nuclei, and some energy is released as a result. If you can get a whole lot of heavy nuclei to undergo fission at the same time, the result is an atomic bomb.
What is Alternative energy source produced from atomic reactions?
Nuclear fission is when a neutron is fired at an element with a high atomic number, which splits and releases more neutrons and energy as a result. Nuclear fusion occurs in stars and experimental reactors.

Can nuclear fission be harmful?
Yes. The first use we developed for nuclear fission was the atomic bomb. The number of people who died when the bombs were dropped on Hiroshima and Nagasaki is difficult to estimate precisely, but was likely over 200,000. Even aside from nuclear weapons, the products of nuclear fission are highly radioactive and fission itself produces large amount of radiation. Accidents at nuclear power plants, which use controlled fission reactions, can result in radioactive material being released into the environment.
