Abstract

This report contains the text of three papers concerning the JET active gas handling plant, presented at a meeting on tritium technology. The first paper gives an overview of the active gas handling system, which receives the exhaust gases from the tokamak and delivers pure protium, deuterium and tritium. Operation is subject to statutory approvals requiring detailed safety reviews. The second paper describes in detail the design of the cryogenic forevacuum system of JET, which collects gas mixtures from the torus and injection systems. It then separates hydrogen isotopes mixtures from helium and impurities and stores them. The third paper gives details of the impurity processing loop, which recovers tritium from the impurities. The latter are fully oxidised in a catalytic recombiner, the tritiated water frozen in a cold trap and subsequently decomposed on hot uranium powder.
