Japan Atomic Energy Agency is developing extraction chromatography technology for MA(III) recovery from spent nuclear fuel. Developments in the extraction chromatography system especially focusing on safety and stable operation are required for practical application of the technology. In this paper, main tasks which have to be challenged preferentially are discussed based on achievements obtained by previous studies and potential MA(III) recovery process flow. For the safety assessment, removal of fine particles, optimization in adsorbent for reduction in pressure drop of the column, degradation behavior of the adsorbents and recycle of the adsorbents are topics for development. Enhancement in resistance against radiation and acid of a material in pump and development of automated operation system are required to maintain product quality during long time operation. Those studies are carried out simultaneously in a research project of 2019-2024, and demonstration with a large scale apparatus will be carried out at end of the project.
