In the research and development of nuclear fusion, getter materials have been widely applied to tritium processing and/or handling techniques such as evacuation, recovery, storage, supply, purification, enrichment, and separation. Some getters have been already developed and applied to tritium handling as well as impurity control in tokamaks. In this paper, we have described the present status of getter applications: (1) plasma-vacuum conditioning, (2) storage-supply-recovery, (3) purification, enrichment and separation, (4) removal and waste management. The improvement of getter properties, however, is required so as to apply them to a wider variety of the unit processes of the tritium handling techniques. It has been pointed out that there is a need for investigations on (1) the activation-deactivation mechanism, (2) absorption-desorption properties and mechanism, (3) durability and/or reactivity against impurity gases, (4) isotope effect and (5) alloying effect.
