In 1998 following the DTE1 tritium experiment 150g of carbon material in the form of flakes and dust were remotely removed from the JET vacuum vessel. Subsequent measurement by calorimetry showed the flake material to contain 0.5g of tritium and a specific activity of 1.1TBq/g. Because of the specific tritium activity and out-gassing, the flakes were not considered to be a subject for disposal as waste but to be processed and the tritium recovered. A facility has been built within the Active Gas Handling System (AGHS) to recover the tritium and eliminate the flake material by its complete oxidation. The process yields HT which can then be transferred into the main AGHS processing loop for isotopic separation. Initially the process will be proven on batch sizes of up to 2g flake material and will eventually be scaled up to 50g batch sizes. This paper describes the inactive commissioning of the flake processing facility and the active processing runs on the flake material.
