Operation of the JET Active Gas Handling System during and after DTEl

摘要

During and after the Deuterium--Tritium Experiment (DTEl) the JET Active Gas Handling System fulfilled all expectations and requirements f it pumped, processed and purified the gases from the Torus and connected systems, isotopically separated hydrogen and supplied l00 g tritium to the machine with only 20 g on JET site which means that the tritium was recycled five times. In addition, it supplied ventilation air detritiation services during interventions inside and outside the Active Gas Handling building. This demonstrated for the first time that high tritium quantities can be recycled safely in connection with a large fusion facility. The paper describes the operation of the Active Gas Handling System.
