Membrane separation technologies : Their application to the fusion reactors fuel cycle
The fuel of future fusion reactors will be a mixture of deuterium and tritium. The deuterium is available by means of the traditional separation technology. The tritium, however, must be produced by means of a nuclear reaction between neutrons and lithium atoms within the reactor breeder which could be a lithiated ceramic material or a liquid metal containing lithium. The tritium produced in the breeder needs a proper extraction process to reach the required purity level. A conceptual modified version of the tritium recovery plant for a solid ceramic breeder, working with two membrane reaction/separation units, is studied in this work. The first membrane unit considered is a catalytic ceramic membrane reactor to remove, via oxidation, the hydrogen isotopes from the purge gas (He), while the second is a Pd/Ag membrane permeator to separate the hydrogen isotopes from the water shift reactor gaseous products.
