| 摘 要： | 采用气-液两相界面模型和与时间有关的扩散理论及本征函数展开的方法,模拟了Li25Sn75合金的氚增殖行为.计算结果表明:在14 MeV能量下,天然Sn的(n,2n)反应宏观截面相对较小,只有1.5 b;7Li、6Li产氚随时间变化的规律与LiPb合金、Li2O介质是一致的;Li25Sn75合金对模型厚度比较敏感,随着厚度和6Li丰度的增加,氚增殖比(Tritium Breeding Ratio,TBR)保持上升的趋势.

| Abstract: | Sn-Li alloy is considered as a potential liquid breeding materials for fusion reactor. For an effective design of the experimental loop for liquid breeder in-pile production tritium and liquid blanket neutronic, in this paper, a mathematical model of gas-eutectic interface and a time-dependent multi-group diffusion equation and eigenfunction expansion method has been introduced and the tritium breeding behavior of liquid Li25Sn75 alloy has been imitated. Calculation results have shown that cross section of ... |
