Abstract Tritium permeability through FeCrAl-oxide-dispersion-strengthened (ODS) ferritic steel containing Ce oxides (Ce-ODS steel) was measured at temperatures ranging from 373 to 623 K. Some of the Ce-ODS steel specimens were oxidized by means of an autoclave treatment at 563 K for 30 days to examine the effect of the surface oxidized layer on the tritium permeability. The tritium permeability obtained for nonoxidized specimen was consistent with that for other common ferritic steels and FeCrAl ferritic steel. For the oxidized specimen, the surface oxide layer suppressed the apparent tritium permeability. The permeability for the oxidized specimen also depended on the atmosphere of the downstream in the permeation experiment: An atmosphere containing water vapor yielded lower tritium permeability compared with a reductive one.

氚渗透通过 Ce-ODS 钢

摘要 在 373 至 623 K 的温度范围内测量了通过 FeCrAl 氧化物弥散强化 (ODS) 铁素体钢（Ce-ODS 钢）的氚渗透率。在 563 K 下高压釜处理 30 天，以检查表面氧化层对氚渗透性的影响。非氧化试样获得的氚渗透率与其他普通铁素体钢和 FeCrAl 铁素体钢的渗透率一致。对于氧化试样，表面氧化层抑制了表观氚渗透率。氧化试样的渗透性还取决于渗透实验中下游的气氛：与还原性气氛相比，含有水蒸气的气氛产生的氚渗透性较低。
