One thing that can happen when a neutron interacts with a uranium atom is called scattering. The neutron "bounces off" the uranium. Aside from scattering, a neutron has a possibility of being absorbed by the uranium nucleus, and this can cause several different reactions, depending on which isotope of uranium is involved in the reaction. It is neutron absorption that is the mechanism utilized in the chain reactions in nuclear weapons and in nuclear reactors. Nuclear fuel, which is often uranium-235, fissions by absorbing a neutron. In the case of uranium-238, we make plutonium by getting that isotope to absorb a neutron. There is a lot more to learn, and you'll find related links below to get you going.
To split a uranium nucleus in nuclear fission, you typically use a neutron to initiate the reaction. When a neutron collides with a uranium nucleus, it can cause the nucleus to split into two smaller nuclei, along with releasing additional neutrons and a large amount of energy.
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.
all you need in nuclear fission is a large element (235Uranium) and a neutron, the neutron goes into the Uranium causeing it to split into smaller parts grapes.
Uranium-238 is fissionable. Its just not what we call fissile, which has the added definition of, when fissioned, producing neutrons that can go on to fission more atoms. Uranium-238 is more correctly called fertile, which means that a neutron can transmute it into another isotope, such as plutonium-239, which is fissionable and fissile.Uranium-235, on the other hand, is both fissionable and fissile.
Stability of a nucleus is dictated by the neutron/proton ratio. Too large or too small and the nucleus is unstable.
A uranium-235 nucleus must absorb a neutron in order to become unstable and split, a process known as nuclear fission. This absorption of a neutron causes the uranium-235 nucleus to become uranium-236, which then splits into two smaller nuclei, releasing additional neutrons and a large amount of energy.
The bullet that starts a fission reaction is a neutron. When a neutron collides with the nucleus of a fissile isotope, such as uranium-235, it can induce the nucleus to undergo fission, releasing more neutrons and a large amount of energy.

The energy in the fission process comes from the splitting of an atomic nucleus into smaller parts. When a heavy nucleus such as uranium-235 absorbs a neutron and splits into two lighter nuclei, it releases a large amount of energy in the form of heat and gamma radiation.
Neutrons are typically bombarded onto uranium-235 nuclei to induce nuclear fission reactions. When a neutron collides with a uranium-235 nucleus, it can be absorbed, causing the nucleus to become unstable and split into two smaller nuclei, along with releasing more neutrons and a large amount of energy. This process is the basis of nuclear power generation and nuclear weapons.

The very large nucleus of the uranium atom is a kind of energy storage unit. The energy of that nucleus is the result of the nuclear synthesis reactions that take place in a supernova. In that sense, a supernova is the energy source of uranium.
Uranium, especially the isotope U235, has a large, unstable nucleus. It's unstable because all the positively charged protons in the nucleus are trying to repel each other. They are being held together by the strong nuclear force. Since strong force can only act over very short distances and the U235 nucleus is so large the nucleus is unstable. It tends to want to split into two smaller and thus more stable elements. When this happens it is called nuclear fission. In nuclear power plants we can split the U235 atom on purpose by hitting it with something. This something is a neutron. The neutron has no charge so it can smash into the nucleus and not just bounce off like proton would. Strangely it all works best if we use a slow moving neutron instead of a fast one. A fast neutron, because of quantum smearing, isn't in one place long enough to have any effect. A slow one, though, can be captured briefly by the U235 nucleus. Once the neutron is captured the nucleus is too large to hold together any longer splits apart. The really neat part is that the mass of the nucleus before it split and the mass of all the pieces afterward are different. Something has gone missing. A very small bit of mass has disappeared. Only Albert Einstein can tell us where it went. His famous equation e=mc^2 tells us that a small amount of mass can become a large amount of energy, and that is just what happens in nuclear fission. The missing mass becomes energy, in this case heat energy. The heat boils water. The steam turns a turbine which spins a generator, making electricity.
Apparently uranium is the largest atom, with 92 protons and 92 electrons.
