Recently, considerable effort has been devoted to improving technologies for tritium recovery in the fusion reactor fuel cycle. Membrane technologies are considered to be an interesting alternative for the fusion fuel process. A mathematical model has been developed to analyse the behaviour of an integrated composite membrane fixed-bed tubular reactor, taking into account the catalytic water shift with carbon monoxide for the tritium recovery from tritiated water. The reactor considered consists of a tubular hydrogen permeable membrane containing the catalytic bed. The shift reaction takes place inside the membrane lumen containing the catalyst, and only the hydrogen produced permeates the reactor wall, moving the reaction towards the products. The hydrogen flux is enhanced by operating with the strip side under vacuum.
