摘要
FDS-MFX(Multi-Functional eXperimental fusion-fission hybrid reactor)是一个基于现实可行技术的多功能聚变裂变混合实验堆概念,分3个阶段相继开展实验研究,分别采用纯氚增殖包层、铀燃料包层和乏燃料包层。本文重点对其中铀燃料包层后期阶段中高浓缩铀模块的摆放方式和尺寸进行优化,给出一个区平均最大功率密度约为100 MW/m3,235U装料量约为1t,氚增殖率为1.05的三维初步中子学方案。
A multi-functional experimental fusion-fission hybrid reactor concept named FDS-MFX ,which is based on viable fusion and fission technologies, has been proposed. Three-stage tests will be carried out successively, in which the tritium breeding blanket, uranium-fueled blanket and spent-fuel-fueled blanket will be utilized respectively. In this paper, the design optimization for the layout and the size of high enriched uranium modules in later stage of uranium-fueled blanket has been performed. Finally, proposing a preliminary three-dimension neutronics design with maximum average Power Density （PDmax） 100 MW/ m^3 , loaded mass of the ^235U 1 000 kg and TBR （Tritium Breeding Ratio） 1.05.
