| Outline of Final Research Achievements |
One of the most important problems in nuclear fuel cycle is to minimize amount and to reduce radiotoxicity of high-level liquid waste generated from spent fuel reprocessing. In this study, to solve these problems, we focus on nuclide separation by column chromatography method and development of novel macroporous silica-based adsorbents having high selectivity for each nuclide such as Cs, Sr, platinum group metals (PGMs) and minor actinide (MA), which are included in high-level liquid waste generated from spent fuel reprocessing. Moreover, column chromatography method separates thses heat-generating nuclides, and the new process can be used for internal irradiation therapy of cancer.
