摘要
从液态金属与氢的相互作用理论出发,进行了氚在液态Pb-17Li中的解吸动力学方面的理论推导。结果表明,氚的释放行为是熔融合金表面反应、扩散与对流综合影响的结果。在此基础上,提出了Pb-17Li辐照离线产氚系统的设计,包括流程设计与描述、实验条件和参数设计,同时还提出了Pb-17Li离线产氚实验的目标及应解决的问题。
In view of the theory of interaction between the liquid metals and hydrogen, theoretical derivation is made from absorption kinetics of tritium from liquid Pb-7Li. The results show that the tritium release is resulted from complex influences of the surface reaction, diffusion and convection of the molten alloy. Based on the derivation;the design is presented for the out-pile reactor tritium release experiment after irradiation from Pb-17Li,including process design and description,design of experimental conditions and parameters. And the target and problems to be solved are also presented in respect of out-pile reactor tritium release experiment. In order to provide technical back-up for the planned experiment, investigation is made into the influence of the carrier gas composition, flow rate, flow mode, breeder temperature on the chemical form and yield of released tritium from Pb-17Li as well as the change of Pb-17Li material properties before and after irradiation.
