A method for homogeneously mixing a uranium/plutonium mixed oxide |
摘要 |
<p>A method for homogeneously mixing a uranium/plutonium mixed oxide which is used for the preparation of a uranium/ plutonium mixed oxide fuel. The method comprises weighing a uranium oxide powder, a plutonium oxide powder, and a dry recovered powder prepared by grinding a uranium/plutonium mixed oxide sinter so as to give a predetermined plutonium enrichment; roughly mixing these powders together by means of a mixer; pulverizing and homogeneously mixing the roughly mixed powder by means of a jet mill (16); discharging the homogeneously mixed powder together with compressed air from the jet mill; and separating the mixed powder from the air by means of a first-stage cyclone (18) to recover at least 90% of the discharged powder. <IMAGE></p> |
