In this study, hydrogen permeation through Flinabe (equimolar LiF + NaF + BeF2 molten salt) including 0.1 wt% Ti particles is experimentally and analytically investigated. Ti particles mixed with Flinabe can suppress H2 permeation for a certain time when the upstream side is supplied with H2. The diffusion time lag after activation process is over 20 times larger than that before activation. H2 diffusion behavior in the Flinabe + Ti system is analyzed using an unsteady-state diffusion equation. The effective diffusivity in the Flinabe + Ti system is around 1/27 of that in the Flinabe system. It is confirmed that the activation of Ti particles is important for the overall permeation process in the Ti-Flinabe system.
