Outline of Final Research Achievements

The experimental results in this study showed feasibility of new extension of extract-able elements which have not been considered in the previous studies, but important ones at the radioactive waste processing. This finding leads to safety enhancement of the waste processing from the point of flammable organic solvent as well as marked reduction of secondary radioactive waste amount. These newly brought advantages are intrinsic. In addition to the advantages, an enhancement of distribution ratios of extracted metal has been experimentally observed; this fundamental demonstration would contribute to an innovative and practical fundamentals of applied technology with a marked reduction of the secondary waste amount.
