Tritium release behavior from neutron-irradiated FLiNaBe mixed with titanium powder

FLiNaBe is a promising liquid blanket material for fusion reactor. Since hydrogen solubility low, one concern the permeation of bred tritium. In order to increase effective hydrogen, addition Ti powder was proposed. this study, influence on behavior tritium generated inside by neutron irradiation investigated. The samples and mixed with 5 wt% 0.5 were prepared solid-state irradiated thermal neutrons at Kyoto University Research Reactor. neutron-irradiated heated 700 °C in an Ar gas flow. released collected water bubbler temporal variation TF HT release observed. Initially, most as from both without but eventually, after long time heating Ti. This result suggests that can decrease very much. amount lower than suppress rate FLiNaBe.
