摘要:

由于不同氢同位素在钯膜上的渗透率存在差异,初步讨论了利用这一特性对氚燃料进行富集的理论可行性。基于中国工程物理研究院针对中国聚变工程试验堆(CFETR)托卡马克排灰气处理(TEP)系统设计的钯膜分离器,构建了多节点钯膜数学模型,对不同进气氘氚比例、进气侧压力、氦灰和其它杂质气体含量以及进气侧流量等参数开展了敏感性分析,详细研究了其对钯膜氚处理能力的影响。结果表明,通过合理的控制进气侧流量与压力,钯膜分离器能够用于调整排灰气中的氘氚比例,达到富集氚燃料的效果。

Abstract:

Due to the differences in the permeability of different hydrogen isotopes on the palladium membrane, the theoretical feasibility of utilizing this property for tritium fuel enrichment was preliminarily discussed. Based on the palladium permeator designed by the Chinese Academy of Engineering Physics for the tokamak exhaust processing (TEP) system of the China Fusion Engineering Test Reactor (CFETR), a mathematical model of the palladium permeator with multi-joints was built and sensitivity analyses were performed for different inlet gas deuterium-tritium ratio, inlet pressure, helium and other impurity gas ratio and inlet flow rate to study in detail their impact on the tritium processing capability of the palladium membrane. The results show that the palladium permeator can be used to adjust the deuterium-tritium ratio in the exhaust gas and achieve the effect of tritium enrichment by properly controlling the inlet flow and pressure.

Key words: CFETR, Tritium, Palladium permeator, Parameter sensitivity analysis
