Present status and future plan of research and development in JAEA on partitioning and transmutation technology for long-lived nuclides

Nuclear Science and Engineering Directorate; Advanced Nuclear System Research and Development Directorate; J-PARC Center

The Japan Atomic Energy Agency has been conducting research and development (R&D) on partitioning and transmutation (P&T) technology for long-lived nuclides in accordance with the Atomic Energy Commission's "Research and Development of Technologies for Partitioning and Transmutation of Long-lived Nuclides-Status and Evaluation Report" issued in 2000. The present report reviews the progress of the investigation on the benefit and the cost of the P&T technology, the international trend of R&D, the progress and the future plan of R&D on the partitioning process and the transmutation cycle technology, together with the necessary infrastructure improvement including the Transmutation Experimental Facility as the Phase-II of the Japan Proton Accelerator Research Complex (J-PARC).
