トカマクにおける内部輸送障壁(ITB)の形成とその特性に関する実験と理論研究の現状について初めてレビューする。特にITBの理論モデリングに関する現状とITBの実験データを世界の9台のトカマク装置から集めた国際ITBデータベースについて述べるとともに、このデータベースを用いてITB形成に必要な実験条件と理論モデルとの比較について述べる。またトカマクの定常運転に関する実験の状況についてレビューし、ITER定常運転シナリオを達成するための課題と展望について議論する。

This paper first reviews the present state of theoretical and experimental knowledge regarding the formation and characteristics of ITBs in tokamaks. Specifically, the current status of theoretical modeling of ITBs is presented; then, an international ITB database based on experimental information extracted from some nine tokamaks is described and used to draw some general conclusions concerning the necessary conditions for ITBs to appear, comparing these with the theoretical models. The experimental situation regarding the steady-state, or at least quasi-steady-state, operation of tokamaks is reviewed and finally the issues and prospects for achieving such operational modes in ITER are discussed.
