Plutonium obtained in nuclear reactors with uranium fuels after recycling of the burned fuels can be used also as a nuclear fuel.

Nuclear fuel is the fuel used to produce nuclear energy.

By reprocessing spent fuel plutonium can be obtained, this can be added to uranium to make a mixed oxide fuel (MOX), so it is a form of recycling, though it is not the original U-235 that is recycled.
