Abstract A Tritium fuel cycle must have the capability to import tritium inventory from transport storage containers enable initial stockpiling and future refresh of inventory. The Joint European Torus (JET) Active Gas Handling System (AGHS) previously imported Amersham uranium beds (U-beds) via a decanting system housed in Analytical Make-up box secondary containment. Due significant operational challenges with this system, new Decanting Facility (TDF) was designed built, U-beds for JET Deuterium–Tritium experiment 2. TDF process design incorporated several changes, including tertiary containment independent purge services supply argon, direct connection AGHS Intermediate Storage system. These changes resulted improvements process, reduction contamination effects off-gassing, reduced time, risk exposure operators. key features their subsequent impact on operation are discussed detail.
