Abstract

The JET Active Gas Handling System (AGHS) was designed, built and commisioned to handle safely radioactive tritium gas mixtures, to supply tritium (T(2)) and deuterium (D(2)) to the JET torus, to process the exhaust gases with the main purpose to enrich and re-use T(2) and D(2), to detritiate impurities and to keep discharges far below the approved daily release limits. In addition, the AGHS had to supply the necessary ventilation air streams during maintenance or repair inside or out of the AGHS building.

During the first Deuterium-Tritium Experiment (DTE1) and JET in 1997 the AGHS fulfilled all these in an excellent manner. No unauthorized or unplanned tritium releases occurred and no operational delays were caused by the AGHS. In fact, this was the first true demonstration that quantities of tritium in the tens of grams range can be processed and recycled safely and efficiently in a large fusion device. As a consequence of the performance of the AGHS during DTE1 we can state confidently that the AGHS is ready for further Deuterium-Tritium experiments. .
