在通往稳态热核聚变反应堆的道路上，完全保护容器免受等离子体边缘的热量和粒子通量影响的概念和实现无疑是最具挑战性的问题之一。Tore Supra自1988年以来完成了一项开创性的工作，从实现长脉冲稳态等离子体放电的角度出发，早期安装了一套高热通量主动冷却组件(模块限制器、内壁)。由于在1996年获得了2分钟持续时间的创纪录放电，循环能量为280MJ，因此与欧洲工业界密切合作，在面向等离子体的组件(PFC)的各种概念上完成了大量的研发。这项研发的主要目的是开发具有大功率密度提取能力(即10 mW/m2)并且表面材料与散热器具有可靠粘结的全氟碳化物。已经进行了大量高性能部件的系列化制造，目前已接近完成。
The conception and realisation of a full protection of the vessel against heat and particle flux at the plasma edge is certainly one of the most challenging issues on the route to a steady-state thermonuclear fusion reactor. Tore Supra has accomplished a pioneer work since 1988 by the early installation of a set of high heat flux actively cooled components (modular limiters, inner wall) in the perspective of the realisation of long pulse steady-state plasma discharges. As 2 min duration record discharges were obtained in 1996 with 280 MJ of circulated energy, a wealth of R&D was accomplished on a variety of concepts for plasma facing components (PFCs), in close collaboration with European industry. This R&D was aimed primarily at developing PFCs with large power density extraction capacity (i.e. 10 MW/m2) and with reliable bonding of the facing material to the heat sink. The series fabrication of a large number of high performance pieces was undertaken and is now mid-way to completion.
