Lifetime Predictions for the First Wall and Blanket Structure of Fusion Reactors: Report on the IAEA Technical Committee Meeting held at Karlsruhe, Federal Republic of Germany, 5–7 November 1985

R. Behrisch, D.R. Harries1986年Nuclear FusionIF 3出版社

With the progress in controlled thermonuclear fusion research, experiments having dimensions approaching those of future fusion reactors and discharge times of the order of 100 to 1000 s have become a necessity. Parameters close to those of ignited plasma are anticipated or achieved in today's four large tokamaks TFTR (Princeton), JET (Culham), JT-60 (Naka-machi) and T-l 5 (Moscow); the burning of a fusion plasma is to be investigated in the next generation of experiments. In these large experiments the load from the plasma on the surrounding vessel walls is considerably increased in duration and intensity compared to that of most previous plasma experiments. The wall load is approaching the values foreseen in a fusion reactor and the lifetime of the wall components represents a major physical and engineering problem.

核融合の制御に関する研究の進展に伴い、将来の核融合炉に近い寸法と100〜1000秒のオーダーの放電時間を持つ実験が必須となっている。点火プラズマに近いパラメータは、今日の4つの大型トカマク装置、TFTR(プリンストン)、JET(カラム)、JT-60(那珂)、T-15(モスクワ)において予測または達成されており、核融合プラズマの燃焼は次世代の実験で調査されることになっている。これらの大規模実験において、プラズマから周囲の真空容器壁への負荷は、従来のほとんどのプラズマ実験と比較して、時間的にも強度的にも大幅に増大している。壁負荷は核融合炉で予想される値に近づきつつあり、壁構成部品の寿命は主要な物理的・工学的問題となっている。
