Nuclear fuel is the fuel that is used in a nuclear reactor to sustain a nuclear chain reaction.These fuels are fissile, and the most common nuclear fuels are the radioactive metals uranium-235 and plutonium-239. All processes involved in obtaining, refining, and using this fuel make up a cycle known as the nuclear fuel cycle.. Uranium-235 is used as a fuel in different concentrations.

All nuclear power plants have a "containment structure" that holds the reactor. And all plants have deep pools where the nuclear fuel when it is no longer being used can be cooled and stored. All nuclear power plants make electricity from the steam created by the heat of splitting atoms. But there are two different ways that steam is used.
