[en] Firstly, this study was analyzed the partitioning process (wet and dry) of each country by reciprocal comparison. Secondly, the outline of tentative partitioning process established by this study was introduced, and the results obtained from the experimental test of this process was evaluated. By the current status of developed partitioning process, the wet process will be more easily industrialized than the dry process in the near future. From the results of experimental test, residual U, MA (minor actinide) such as Am and Np, and Tc as a long-lived nuclide of PGM (platinum group metal) could be effectively separated from the simulated radwaste solution. Except for the supplementary purification process to purify the Am, overall separation of Np in the same step, and treatment of Fe which was still remained in final organic phase, this tentative process has not any problems. To transmute the long-lived nuclides partitioned in the future, however, MA such as U, Am and Np, and Tc were required to separate mutually and/or to separate Tc only, because of the difference on transmutation methodology of these elements. Therefore, a new separation process to overcome the above problems was suggested, but further study would be required to identify this process in the practical engineering point of view.
