摘　　要：使用有限元程序对聚变次临界堆双冷嬗变包层第一壁进行数值模拟 ,给出不同载荷条件下的温度场和应力场分布 ,结果证明典型氦气系统设计满足热工要求。依据数值模拟结果对第一壁氦气载热能力进行分析 ,并考虑了流道形状对结构热应力的影响。The finite element code is used to simulat e the first wall (FW) structure of dual-cooled waste transmutation blanket (DWTB) for the fusion driven sub-critical system (FDS). The temperature and stress fi eld on the condition of different heat loads have been presented. It is shown th at typical Helium gas system can meet the requirement of thermal-hydraulic desi gn. The ability of helium gas removal heat in FW has been analyzed, and the infl uence of the shape of FW flow channel on thermal stress have been considered.
