Outline of Final Research Achievements

We have proposed a completely new concept of a fusion reactor that combines ultra-high-energy 14 MeV neutrons generated by fusion reactions with high-level waste (fission products and minor actinides) contained in spent nuclear fuel produced by nuclear power plants. We have performed designing of the minor actinide fuel and transmutation system, and also the blanket including the fission products transmutation system. We have indicated successful scenarios that it is possible to surely reduce the domestic storage amount of these high-level wastes by introducing the innovative fusion reactors to Japan.

Academic Significance and Societal Importance of the Research Achievements

本研究では、核分裂生成物やマイナーアクチノイドを有効に利用した新しい核融合炉の概念設計を行い、高レベル廃棄物の地層処分以外の選択肢を示すことにより、現在の原子力エネルギー問題を解決すると同時に、核融合炉に対するコスト低減の要求を緩和することによって、核融合炉の近い将来における意義の明確化を行った。
第5期科学技術基本計画にある、第3章「経済・社会的課題への対応」に記載されている「将来に向けた重要な技術である核融合炉等の革新的技術、核燃料サイクル技術の確立」を同時に解決する研究内容であり、新しい核燃料サイクルの未来図を示し、原子力エネルギーの社会的受容性を格段に向上させる可能性を持っている。
