Outline of Final Research Achievements

To separate Cs(I) and Sr(II), which are heat-generating nuclides, from high-level liquid waste (HLLW) generated from spent nuclear fuel reprocessing selectively and efficiently, an innovative separation process of the nuclides have been developed by using novel macroporous silica-based adsorbents based on extraction chromatography method. Moreover, a new purification process of the recovered nuclides based on extraction chromatography method was investigated and the process was used for internal irradiation therapy of cancer is proved and radiotherapy technique using a novel Y-labeled radiopharmaceutical.
