Hydrogen transfer under a fluidized condition of Li-Pb is investigated experimentally to design a Li-Pb blanket system. Li-Pb eutectic alloy flows through inside of a Ni tube in the experimental system, where H2 permeates into and out of the forced Li-Pb flow. The overall H2 permeation rate is analyzed using a mass balance model. Hydrogen atoms diffuse in Ni and Li-Pb. The steady-state H2 permeation rate obtained by this experiment is smaller than the result of the calculation model. A resistance factor is introduced to the present analysis in order to evaluate the influence of other H2 transfer mechanisms, such as diffusion in Li-Pb and dissolution reaction between Ni and Li-Pb. The contribution of the resistance to the overall H2 permeation rate becomes large when the flow rate of Li-Pb is low. This is because the boundary layer thickness between Ni and Li-Pb affects the overall H2 permeation rate. When the flow velocity of Li-Pb is large, the thickness of the boundary layer becomes thin, and the driving force of H2 permeation through Ni wall becomes large.
