The systems and process of tritium decontamination for helium cold solid blanket module in the hot cell are considered, three-layer cladding design was used to make sure the safe consideration, among them the second containment system includes the vacuum furnace and glove box, the principle of the vacuum furnace and process of tritium decontamination steps of the blanket is carefully described, high temperature baking and catalytic oxidation technology are employed to remove the tritium. Until the content of tritium lower than the standard of national emission after repeatable tritium removal，which is detected using the method of ionization chamber. The preliminary process of tritium decontamination for the helium cooled solid-state blanket of CFETR is completed, which provides a reference for the design and construction of CFETR hot cell in the future.

设计了CFETR氦冷固态包层在热室中的除氚方法和工艺流程，热室内的除氚系统采用三层包覆的安全冗余设计，其中次级包容系统设计有高温真空炉和手套箱。采用高温烘烤和催化氧化技术，经过反复循环除氚后，直到电离室检测到的气体含氚量达到国家设定的排放标准后稀释排放式固化储存，完成热室内包层模块的深度除氚。
