The NET (Next European Torus) reactor design is conceived with removable internal components (first wall, divertor plate, breeding blanket), both to prolong its operational lifetime and to facilitate testing of different materials. The internals can be removed only if the coolant and breeder piping systems are remotely connected and disconnected from the permanent main circuits. Although a welded connection could be envisaged between the main circuits and the movable parts, a flanged connection seems easier to handle. A new type of flange has been designed to be assembled in two units facing each other, the system working as a pressure boundary by means of two flexible parts in direct contact without an `O-ring'. The flange geometry is designed to obtain a pressure boundary efficiency proportional to the pressure itself. At present, the flange has been optimised for materials and piping systems relevant to the NET reactor.
