ITER托卡马克排气处理（TEP）系统的设计目标之一是在氚工厂的正常排气口除氚系统中损失不超过10（-5）gh（-1）。因此，等离子体废气需要以实现相对于流速约108的氚去除效率的方式进行处理。用氚浓度表示，这相当于从约130 gm（-3）降到约10（-4）gm（-3）（约1 Cim（-3）= 3.7*10（10）Bqm（-3））的去污。ITER TEP系统的三步参考过程称为CAPER，已在卡尔斯鲁厄氚实验室（TLK）开发和实现。作为第三步的关键组成部分的PERMCAT反应堆成功调试后，对涉及处理300克以上氚的3个步骤进行了详细的参数氚测试，并证明了每个工艺步骤和整个工艺的去污系数超出了设计要求。不仅ITER要求的10（8）的去污因子，而且TEP作为不同来源气体的废物堆的操作模式已经在CAPER设施上进行了实验验证。
One of the design targets for the Tokamak Exhaust Processing (TEP) system of ITER is not to lose more than 10(-5) gh(-1) into the Normal Vent Detritiation system of the Tritium Plant. The plasma exhaust gas therefore needs to be processed in a way that a tritium removal efficiency of about 108 with respect to the flow rate is achieved. Expressed in terms of tritium concentrations this corresponds to a decontamination from about 130 gm(-3) down to about 10(-4) gm(-3) (about 1 Cim(-3) = 3.7*10(10) Bqm(-3)). The three step reference process for the TEP system of ITER is called CAPER and has been developed and realized at the Tritium Laboratory Karlsruhe (TLK). After the successful commissioning of the PERMCAT reactor as the key component of the third step detailed parametric tritium testing of the 3 steps involving the processing of more than 300 g tritium has been carried out and decontamination factors beyond the design requirements have been demonstrated for each process step and for the process as a whole. Not only the decontamination factor of 10(8) as required by ITER, but also the operational mode of TEP as a waste dump for gases from diverse sources has been experimentally validated with the CAPER facility.
