Summary  

In order to develop the partitioning-transmutation system for the reduction of high-level radioactive wastes, the group and mutual separation of actinides and rare earth elements in spent fuels is required. In the present work, a chromatographic separation of trivalent actinides (Am and Cm) and rare earth elements was examined in hydrochloric acid/methanol mixed solvents by using a pyridine resin embedded in high-porous silica beads. In a 70 vol% hydrochloric acid (11.7 mol HCl/dm3)/30 vol% methanol mixed solvent, the elution curves of the trivalent actinides were separated completely from those of rare earth elements at room temperature. The present paper discusses the separation behavior of trivalent actinides and rare earth elements as a function of flow rate, temperature and solvent compositions.
