They are many but the most famous three are: uranium-233, Uranium-235, and Plutonium-239.
Another answerUranium-235, uranium-238, and plutonium-239 are all capable of undergoing neutron induced fission. Actually there are other isotopes that also do this, but they are not commonly used as fuel.Wiki User

What three isotopes that can undergo nuclear fission?
There are many isotopes, especially of the trans-Uranium elements which can undergo nuclear fission. The isotopes which are used in nuclear reactors are Uranium-233, Uranium-235 and Plutonium-239, because these isotopes are more readily available than other fissionable isotopes. Uranium-235 occurs naturally, Uranium-233 can be made by neutron irradiation of Thorium-232 and Plutonium-239 can be made by neutron irradiation of Uranium-238.
Atoms that naturally undergo nuclear fissions are called?
These are called fissile or fissionable. Fissile isotopes undergo fission, producing sufficient neutrons of sufficient power that a chain reaction can happen, if there is enough of the isotope to support it. The mass sufficient to support a chain reaction is called critical. Atoms of fissionable isotopes will undergo fission when a sufficiently energetic neutron collides with them, but the neutrons they emit when they divide are either insufficient in number or insufficient in energy to sustain an chain reaction. There is a third type of material that can undergo fission, called fertile, which is isotopes that can be caused to capture neutrons, changing into fissile or fissionable isotopes, so the fission does not happen to atoms of the fertile material directly, but to the atoms of the isotopes they become.

Does nuclear fission take place in an uranium bar?
Yes, with a rather unimportant qualification. There are isotopes of uranium that do not undergo fission, but it is unlikely a bar would be made from any of them because they have short half lives and are expensive to produce.
Why fission cannot take place with fast neutron?
In order to cause an atomic nucleus to become unstable so that it will undergo fission, you have to add a neutron. If a slow neutron collides with an atomic nucleus, it will be absorbed into the nucleus and become part of it. The nuclear attraction of the nucleus is strong enough to grab a slow neutron. But a fast neutron cannot be captured because it has too much kinetic energy. The attraction of the nucleus is not enough to stop the motion of a fast neutron. Even if a fast neutron makes a direct hit on an atomic nucleus, it is just going to bounce off.
What causes a splitting nucleus?
The capture of a neutron can split a nucleus - but only for certain isotopes like U-235 and Pu-239. Two naturally occurring isotopes undergo spontaneous fission, meaning the nucleus splits without neutron capture. These are 235U and 238U. A few other isotopes undergo spontaneous fission, but these are produced by an earlier neutron capture. Spontaneous fission is the result of quantum tunnelling, which is rather difficult to explain.

How is a uranium-235 nucleus made to undergo fission?
Nuclear fission is the splitting up of big atomic nuclei. Uranium is quite a large nuclei. Each time a uranium atom splits up, it spits out two or three neutrons. One of which might hit another nuclei causing it to split - thus keeping the chain reaction going. The uranium atom - when hit by a neutron splits into Barium and Krypton.
Is fission the same as when was first invented?
Fission is not an invention. Fission is a natural process, and its functioning is not subject to change. The only materials ordinarily found in nature that undergo fission are various isotopes of uranium. The neutrons released from this process occasionally produce isotopes we usually regard as synthetic, but in such small amounts that for practical purposes they do not exist on earth. Some did, however, exist in the distant past, and probably still do in other parts of space. Nevertheless, in connection with this question, it can be pointed out that people have studied a number of substances that can undergo fission that are only produced synthetically. While the functioning of fission is changeless, the understanding of fission changed substantially in the course of these investigations.

How is the energy in the reactor made to drive a turbine?
The fuel in the core of a nuclear reactor goes into a chain reaction of nuclear fission. This happens because atoms of some isotopes in the fuel undergo spontaneous fission, producing neutrons, which cause other atoms to undergo fission, and so on. The fission produces a lot of heat. The heat is typically used to boil water, which is used to turn a turbine. And finally, the turbine turns a generator to make electricity.
What is mearnt by fission cross-section?
In nuclear physics, a cross section is essentially the probability that a nucleus will interact with something. An isotope with a high fission cross section, like U-235, is very likely to absorb a thermal (slow) neutron and undergo fission. The cross section has units of area, usually cm2, which is where the name comes from. When the cross section is multiplied by the neutron flux, the product is the fission rate, or number of fissions per second.
Why fission cannot take place with fast neutron?
In order to cause an atomic nucleus to become unstable so that it will undergo fission, you have to add a neutron. If a slow neutron collides with an atomic nucleus, it will be absorbed into the nucleus and become part of it. The nuclear attraction of the nucleus is strong enough to grab a slow neutron. But a fast neutron cannot be captured because it has too much kinetic energy. The attraction of the nucleus is not enough to stop the motion of a fast neutron.

What organisms undergo fission?
An organism that can undergo binary fission would be a plan ol prokaryotic cell or a protozoan if you want something specific.
