Japanese perspective of fusion nuclear technology from ITER to DEMO

Tanaka, Satoru*; Takatsu, Hideyuki

The world fusion community is now launching construction of ITER. In parallel with the ITER Program, Broader Approach activities also started this year by the collaboration of Japan and EURATOM. The Atomic Energy Commission of Japan reviewed the on-going Third Phase Basic Program of Fusion Research and Development, and then issued the Report in November 2005. This report presented a roadmap toward the DEMO and beyond and identified research and development items on fusion nuclear technology indispensable for fusion energy utilization. In the present paper, Japanese view and policy on ITER and beyond will be summarized mainly from the viewpoints of fusion nuclear technology, and a minimum set of research and development items on fusion nuclear technology toward DEMO and essential for fusion energy utilization are overviewed.
