Abstract
MOX fuel which stands for Mixed Oxide fuel is one of the most realistic options for utilizing plutonium as an energy resource in the future with nuclear fuel cycle system including breede reactors.
Development of MOX fuel is undertaken in Tokai Laboratory of PNC (Power Reactor and Nuclear Fuel Development Corporation) faced with the PNC's breeder reactor program.
In the text, features of nuclear fuel, completely different from fossil fuel, and state of the art of MOX fuel development is discribed plain.
