To clarify plutonium and americium redistribution behaviors of mixed oxide fuel in fast reactor, by using test results of Am bearing mixed oxide fuel irradiated for short term in the fast experimental reactor “JOYO”, we evaluated influence of oxygen-to-metal ratio on plutonium and americium redistribution behaviors.
