聚变发电反应堆双冷锂铅包层结构温度和应力计算分析

Temperature and stress calculation and analysis on the dual-cooled lithium-lead breeder blanket structure for the fusion power reactor FDS-Ⅱ

使用有限元程序对聚变发电反应堆FDS-Ⅱ双冷锂铅包层结构进行数值模拟,依据结构设计、热工水力学参数和中子学计算参数,给出对应包层结构温度场和应力场分布,同时分析了液态金属LiPb碳化硅流道插件的温度、应力及变形。依据温度场和应力场模拟结果,对FDS-Ⅱ双冷锂铅包层设计方案在等离子体稳态运行条件下进行可行性分析。

The finite element code is used to simulate the dual-cooled lithium-lead breeder blanket structure for the fusion power reactor（named FDS-Ⅱ）. The temperature and stress field have been presented for the whole blanket structure on the basis of the structure design, the thermal-hydraulic design and the neutronics design. The temperature field, stress field, thermal deformation of SiCf/SiC FCI in the liquid metal LiPb flow channel have been also presented. The feasibility of the DLL blanket structure design of FDS-Ⅱ has been analyzed based on the above results.
