The Exhaust Detritiation System (EDS) of the JET Active Gas Handling Plant has operated continuously for the last three years. The system has been used during the active commissioning phase, during the DTE1 deuterium-tritium experiment and subsequently during the Remote Tile Exchange (RTE) operation. The Exhaust Detritiation System is one of the key safety systems which permits the operation of the JET machine with tritium. This paper describes the experience gained of operating the Exhaust Detrititaition System throughout the tritium operations at JET. The design [1] and the construction and commissioning [2] of the Exhaust Detritiation System have been discussed previously.
