The research programme of the Joint Research Centre includes advanced studies on tritium technology with a view to using tritium as a fuel in controlled fusion reactors. For this purpose, construction and testing are now almost complete on ETHEL (European Tritium Handling Experimental Laboratory), in which global quantities of HT amounting to 100 g will be handled, with individual experiments using quantities up to 20 g. Tritium permeates and spreads through all materials and therefore it has been necessary to equip the laboratory with sophisticated monitoring systems in order to control the confinement of the radioactive gas at all times and to detect any contamination as early as possible. This study illustrates and comments on the criteria which have been taken as a reference for the design of the independent systems of active and passive control installed to ensure the safe operation of the laboratory. The calibration methods and controls on reliability and proper operation which have been implemented are also described.
