Abstract

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.
