摘　　要：聚变堆工程设计中,氚在聚变装置部件材料中的扩散、渗透、滞留是十分重要的问题。为便于开展氚的行为分析研究,基于Python语言,开发了聚变堆一维结构材料中氚输运计算程序JD-CF。该程序可对一维平板、一维圆柱与一维球形的连续或多层结构模型所涉及的氚输运问题进行分析,还可实现传质与传热的耦合计算。将JD-CF程序与相关实验结果、TMAP模拟程序以及ANSYS软件的结果进行验证,符合较好。结果证明,JD-CF程序具有较高的精度,并可以满足气体/等离子体注入实验、热脱附实验、瞬态/稳态氢氘的浓度及温度分布模拟、通量变化模拟的需求,对于解决聚变堆结构材料内氚扩散、氚滞留等问题有一定参考价值。The diffusion,permeation and retention of tritium in the component materials are essential for the engineering design of fusion reactor.In order to facilitate the research of tritium behavior,based on Python the tritium transport calculational program named JD-CF in one-dimensional structural materials of fusion reactor was developed.JD-CF program can calculate the tritium transport problem based on the continuous or multi-layer structure model of one-dimensional flat plate,one-dimensional cylinder and one-dimensional sphere,and realize the coupling calculation of mass and heat transfer.The JD-CF program is verified with the relevant experimental results,TMAP simulation programs,and the results of ANSYS software,which is relatively agreeable.The results show that the JD-CF program has high accuracy and could satisfy the requirements of gas/plasma injection experiment,thermal desorption experiment,transient/steady-state hydrogen and deuterium concentration and temperature distribution simulation,and flux change simulation,it has important reference value for solving the problems of tritium diffusion and tritium retention in the structural materials of fusion reactor.
