21世紀中頃のエネルギー源確保を目指して核融合炉の開発研究が国際協力で行われている。核融合炉は核分裂炉に比べて安全性に優れている反面、超高温プラズマ,14MeV中性子照射,真空,電磁力,液体ヘリウム冷却等,構造物にとっては苛酷な条件に晒される。将来の動力炉第一壁について課題と展望について述べる。

Research and development of nuclear fusion reactors have been internationally conducted to obtain the energy source in the middle of 21st century. The nuclear fusion reactor has safer characteristics than the nuclear fission reactor. But its structural materials are subjected many severe mechanical conditions such as very high temperature, 14MeV neutron flux. This paper describes the prospect and issues in the fusion power reactor design study from the point of view of the first wall.
