Uranium 235....but Uranium 238 is also present and will absorb a neutron and become Plutonium 239 and adds approximately 10% of the net power in most commercial fuels used in the USA.
Most people are not aware that a reactor produces many transuranic elements, not just Plutonium, and that all of these elements have isotopes suitable for reactor fuel.
The uranium 235 atoms in the nuclear fuel are what actually fission, or split into two other atoms. The uranium is in ceramic fuel pellets that are inserted into fuel rods, that make up fuel elements, that are in the reactor core that is located in the reactor vessel of the nuclear power plant. After the fuel has been in the reactor it begins to produce plutonium 239 atoms within the fuel which will also undergo a fission reaction.
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
The part of a nuclear power plant that undergoes a fission reaction is called the reactor core. This is where the nuclear fuel, such as uranium or plutonium, is housed and where the chain reaction occurs to produce heat energy.
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.
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.
In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
No, fission is still a fuel in - waste out reaction. Eventually the supply of nuclear fuel would run out.

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.
The element most commonly used as a fuel in nuclear fission reactions is uranium-235. It is a naturally occurring isotope of uranium that can sustain a chain reaction under controlled conditions in nuclear reactors.
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
The first time a fission chain reaction was produced was in 1942
Nuclear fuel rods contain uranium pellets for the fission reaction. The uranium pellets undergo a controlled chain reaction in a nuclear reactor, releasing heat energy that is used to generate electricity.
