Thermal-hydraulics design and analysis on the dual-cooled lithium-lead breeder blanket for the fusion power reactor FDS-Ⅱ

依据结构设计和中子学计算结果给出了聚变发电反应堆FDS-Ⅱ双冷锂铅(DLL)包层热工水力学设计方案。采用数值计算软件对液态金属增殖区LiPb流场和第一壁热-结构等进行了模拟,并对功率转换系统的热效率进行了计算。通过分析评估,证实该包层热工水力学方案能较好地实现FDS-Ⅱ聚变发电反应堆预期目标。

Based on the structure design and the results of the neutronics calculation, the thermal-hydraulics design scheme on the Dual-cooled Lithium Lead （DLL） Breeder Blanket for the fusion power reactor （named FDS-Ⅱ ） is presented. The numerical calculation codes are used to simulate LiPb flow fields of breeder zones and thermal-structure of First Wall. The thermal efficiency of the power conversion system is calculated. The results validate the thermal-hydraulics scheme can achieve the anticipative objects of FDS- Ⅱ.
