摘要: 为研究氚自持条件，建立了Z-FFR氚分析模型，基于理论方程和氚平均滞留时间方法进行计算，得到稳态运行时排灰气处理系统、氚增殖提取系统、同位素分离系统、水去氚化系统的氚质量流分别为52.30，25.40，81.30，3.60 g/day，对应的氚盘存量为52.30，25.40，8.13，1.80 g。同时以氚质量流推导出氚自持判断条件，分析了设计参数能够满足氚自持要求，同时获得了燃烧效率、氚增殖率、提取效率与氚自持的互补关系，三者作为关键参数相互依存，于临界值、设计值、理想值之间分析了氚的自持情况。Abstract: Tritium self-sufficiency of Z-pinch driven fusion-fission hybrid reactor (Z-FFR) is the basis of its long-term operation. In order to analyse the conditions of tritium self-sufficiency, a modified tritium fuel cycle model and equations of Z-FFR based on mean residence time calculation method were established. Through theoretical analysis and calculation, the tritium mass-flow of Z-pinch exhaust processing system(ZEP), tritium extraction system(TES), isotope separation system(ISS), water detriation system(WDS) were got. The results of tritium mass-flow are 52.30, 25.40, 81.30, 3.60 g/day, and tritium inventory are 52.30, 25.40, 8.13, 1.80 g. Meanwhile, criteria of tritium self-sufficiency were given out based on mass-flow. The design parameters can meet this requirements. Then the complementary relationship of burning rate, tritium breeding ratio and extraction efficiency under tritium self-sufficiency critical condition were analyzed.
