摘要：

DEMO requires a novel fuel cycle architecture with Direct Internal Recycling in order to drastically minimize the tritium inventory. One central element of this architecture is the separation (and compression) of hydrogenic gas from the exhaust gas stream, close to the divertor, which can immediately be recycled to feed the matter injection systems. The hydrogen-selective separation will be achieved by the metal foil pump, a novel pump type relying on the effect of superpermeation, which is a first-of-its-kind application for the conditions to be matched for DEMO. To achieve a convincing performance, each hydrogen particle has to undergo successfully a series of processes before it is separated and pumped. To support the design of such a pump, a comprehensive R&D programme has been started which is currently being focused on (i) the plasma source, (ii) the transport of the suprathermal hydrogen, and (iii) the material and surface aspects of the foil. The experimental and modelling tools are described, examples of recent results are presented and a first prediction on the performance is derived.
