Keywords:Minor Actinides, Separation, Storage

For the scenario in which Minor Actinides(MA) are separated from high-level liquid waste and stored in several 10 years scale until the practical application of nuclear transmutation of fast reactors, etc., technology development is carried out on solvent extraction which is easy for waste treatment, direct conversion of the extract liquid to oxide, and solid solubilization of MA to fluorite structure(IV). In Part 2, the functional requirements and expected effects of the concept of MA separation and storage technology were extracted as targets of the concept.
