Feasibility of Chemical Getter Beds in Scavenging Tritium from Inert Gases

Chemical getters can be used to scavenge tritium from inert gases. Cerium, which forms a hydride with a low dissociation pressure, has a high reactivity and is relatively inexpensive. It is a good candidate getter material for such a scavenger system. Mathematical models for fixed and fluidized bed reactors predict satisfactory performance. Therefore, the gettering concept warrants further investigation.
