Outline of Final Research Achievements

Many kinds of elements are contained in the nuclear spent fuel. Some of them are valuable elements. Some of them constitute a limitation factor of the amount of high-level waste in vitrified waste and the emplacement area for high-level waste disposal. Thus, the separation of these elements is required. For the development of nuclide separation method from the spent fuel, the basic study on the atmospheric-pressure non-thermal plasma chemical conversion and the dissolution of spent fuel was carried out, novel solid-type extractants were developed and the nuclide separation using the developed extractants was investigated.
