英文摘要	With the method of gas-driven permeation, a series of permeation experiments was carried out using Hastelloy N alloy membrane in an elevated temperature range of 400 degrees C to 800 degrees C with different hydrogen isotopes. A complete set of permeability, diffusivity, and Sieverts' constant for hydrogen and deuterium in Hastelloy N alloy was successfully obtained. The isotope effect in the diffusion process was analyzed and compared with references. The ratios of diffusive transport parameters for hydrogen and deuterium were a permeability ratio of CYRILLIC CAPITAL LETTER EFH/CYRILLIC CAPITAL LETTER EFD = 1.32exp(0.34kJ/RT), a diffusivity ratio of D-H/D-D = 1.15exp(-0.41kJ/RT), and a Sieverts' constant ratio of K-S,K-H/K-S,K-D = 1.16exp(0.21kJ/RT). The result that the permeation flux of deuterium was decreased after introducing hydrogen could be used to suppress the permeation of tritium in future tritium control of the Fluoride-salt-cooled High-temperature Reactor (FHR). Compared with NiO, the Cr2O3 formed in the surface oxidation layer of Hastelloy N alloy showed better hydrogen permeation barrier performance after baking above 700 degrees C in air.
