Am(III) and Cm(III) recovery experiments with the extraction chromatography technology were carried out on genuine HLLW obtained by reprocessing of the Fast Reactor fuel. Modification of the flow-sheet with 2 steps column operations using CMPO/SiO$$_{2}$$-P and HDEHP/SiO$$_{2}$$-P adsorbents achieved more than 90% recovery yields for Am(III) and Cm(III) with decontamination factor of 1000 for Eu(III). This is a significant progress in development of the technology for the implementation.
