Permeation of hydrogen isotope through a high-temperature alloy as used heat exchanger and reformer tubes is an important problem in the hydrogen production system connected to be the high-temperature engineering test reactor (HTTR). The objective of this study is to investigate an effect of mutual permeation process of hydrogen (H_2) and deuterium (D_2) on an amount of permeated D_2 through tubes. From the results obtained in this experiment, when the partial pressure of D_2 was kept at 100Pa in the tube inside and the one of H_2 was lower than 10kPa in the tube outside, the amount of permeated D_2 in the case of mutual permeation was larger than the one in the case of ordinary permeation. On the other hand, when the partial pressure of H_2 was larger than 10kPa, the amount of permeated D_2 decrease with increasing the partial pressure of H_2 in the tube outside. This paper described a permeability of hydrogen and deuterium for Inconel 600 and effectiveness of mutual permeation on the amount of permeated D_2.
