Operation of the JET Active Gas Handling System during and after DTE1

During and after the Deuterium-Tritium Experiment (DTE1) the JET Active Gas Handling System fulfilled all expectations and requirements: it pumped, pr ocessed and purified the gases from the Torus and connected systems, isotop ically separated hydrogen and supplied 100 g tritium to the machine with on ly 20 g on JET site which means that the tritium was recycled five times. I n addition, it supplied ventilation air detritiation services during interv entions inside and outside the Active Gas Handling building. This demonstra ted for the first time that high tritium quantities can be recycled safely in connection with a large fusion facility. The paper describes the operati on of the Active Gas Handling System. (C) 1999 JET Joint Undertaking. Publi shed by Elsevier Science S.A. All rights reserved.
