During 1997 JET was operated for an extensive period using a D-T mixture (DTE1). The use of tritium in the machine required a number of changes in the design and operation of diagnostic systems.

All diagnostics with a direct vacuum interface with the main vessel have been fitted with tritium compatible pumps and their exhaust gases have been re-routed to the Active Gas Handling Plant. All items on the torus, which could lead to significant leakage in the event of failure, were required to have double containment. Therefore, all windows, and the majority of bellows and feed-throughs, were designed and installed with a double barrier, making a total of some 330 interspaces. .
