Fission product behaviour in minor actinide-bearing metal fuel

Abstract

EDS analysis was performed on irradiated MA-bearing metal fuel samples. Fuel alloy is segregated into a few phases of different Zr peak intensity. RE-rich precipitates include Zr, Y, Mo, MAs and/or noble metal elements. Single Zr phase is formed in the periphery of the fuel.JRC.E.2-Safety of Irradiated Nuclear Material
