JT-60 U有多种壁面处理方法，如真空容器烘烤、氦泰勒放电清洗、氦辉光放电清洗、托卡马克放电清洗和硼化。利用这些壁面调节方法，JT-60 U的碳基第一壁已成功地进行了大功率运行。研究了碳基第一壁的材料行为，获得了有关机械工程和等离子体表面相互作用的重要知识。为了了解氚在JT-60 U中的行为，测量了氚在第一壁中的滞留和通过泵系统的氚排出。这些结果产生有用的信息，在未来的DT聚变机的氚行为。
JT-60U has a variety of wall-conditioning methods such as baking of the vacuum vessel, helium Taylor discharge cleaning, helium glow discharge cleaning, tokamak discharge cleaning, and boronization. Using these wall-conditioning methods, the high-power operation of JT-60U has been successfully carried out with the carbon-based first wall. The material behavior of the carbon-based first wall has been investigated, and important knowledge was obtained on mechanical engineering and plasma surface interactions. In order to understand the tritium behavior in JT-60U, tritium retention in the first wall and tritium exhausted through the pumping system were measured. These results yield useful information on the tritium behavior in a future DT fusion machine.
