Summary:helium-3 influence was analyzed by combining with the Ortman model. The results showed that helium blanketing effect affected the adsorption performance of Zr0.85Ti0.15Co alloy significantly, but the blanketing effect could not completely inhibit the tritium absorption reaction, and it could continue to absorb tritium at a low rate until the adsorption was completed. The completion time of tritium absorption was mainly affected by helium-3 concentration when helium-3 concentrations was low, while when the helium concentration was high, it was mainly affected by the initial tritium partial pressure. Helium-3 blanketing process included two steps, that was “bulk flow” and “diffusion flow”, and Ortman model could predict the helium shielding pressure in “bulk flow”.
