ITER Physics Basis出版以降のITPA輸送・閉じ込め(TC)グループにおけるプラズマ輸送と閉じ込めの物理理解と理論モデル開発の進展を、ITERと燃焼プラズマの予測・制御への貢献に焦点を当ててまとめた。本論文は、過去15年間のITPA TC共同実験/共同活動によって主に導かれた進歩について、一般的かつ合理的な概観を提供するものである。本論文は、ITPA TCグループの科学的な戦略とスコープ、主要な進歩の全体像から始まり、粒子輸送、不純物輸送、イオン・電子乱流熱輸送、運動量輸送、3次元磁場が輸送に与える影響、閉じ込めモード遷移、大域的閉じ込め、簡約化輸送モデルといった各研究分野の進歩を示す。

Progress in physics understanding and theoretical model development of plasma transport and confinement in the ITPA Transport and Confinement Topical Group since the publication of the ITER Physics Basis was summarized focusing on the contributions to ITER and burning plasma prediction and control. This paper provides a general and streamlined overview on the advances that were mainly led by the ITPA TC joint experiments and joint activities for the last 15 years. This paper starts with the scientific strategy and scope of the ITPA TC Topical group and overall picture of the major progress, followed by the progress of each research field: particle transport, impurity transport, ion and electron thermal turbulent transport, momentum transport, impact of 3D magnetic fields on transport, confinement mode transitions, global confinement, and reduced transport modeling.
