ImPACT International Symposium on
“New Horizons of Partitioning and Transmutation
Technologies with Accelerator System”
2-3 December 2018, at The University of Tokyo

Hosted by
Cabinet Office of the Government of Japan (CAO)
Japan Science and Technology Agency (JST)
RIKEN Nishina Center for Accelerator-Based Science

Overview

Reduction of high-level radioactive waste is one of the major goals of sustainable development for society. Research and development into the reduction using partitioning and transmutation (P&T) technology have been conducted over recent decades in the world. Very recently in Japan an R&D program dedicated for long-lived fission products, entitled “Reduction and Resource Recycling of High-level Radioactive Wastes through Nuclear Transmutation” is being conducted in the “ImPACT” organization in the Cabinet Office. This program depicts a strategy based on even-odd laser separation and transmutation using an accelerator system, and the strategy is being strengthened by new scheme for chemical separation, newly developed reaction database and new ideas for efficient laser separation scheme as well as a high-power accelerator. In this symposium, by introducing the R&D activities in the ImPACT program, the world-wide P&T activities and the related topics are overviewed and discussed to achieve the reduction of high-level radioactive waste in future.
