An advanced reduced activation alloy (ARAA) is a reduced activation ferritic/martensitic (RAFM) steel under development in Korea. The first complete data set of parameters (permeability, diffusivity, solubility, trap site density, and trapping energy) for tritium transport in an ARAA was theoretically estimated using a model developed by Ebisuzaki et al . assuming a quantum harmonic approximation. Our results for tritium transport in an ARAA are also compared with the results for tritium transport in an RAFM steel OPTIFER IVb previously reported by Esteban et al .

使用量子谐波近似估计高级减少活化合金中的氚输运

先进的低活化合金 (ARAA) 是韩国正在开发的低活化铁素体/马氏体 (RAFM) 钢。使用 Ebisuzaki 等人开发的模型，理论上估计了 ARAA 中氚传输的第一个完整参数数据集（渗透率、扩散率、溶解度、陷阱位点密度和陷阱能量）。假设一个量子谐波近似。我们在 ARAA 中氚传输的结果也与 Esteban 等人先前报道的 RAFM 钢 OPTIFER IVb 中氚传输的结果进行了比较。
