摘　　要：在聚变次临界堆双冷嬗变包层第一壁结构初步设计基础上 ,对第一壁结构尺寸和氦气流道形状进行优化分析 ,利用有限元分析软件对第一壁结构进行应力数值模拟 ,在满足结构应力及部件可靠性的前提下 ,给出最佳优化方案。On the basis of mechanic calculation and analysis of fir st wall (FW) structure of the dual-cooled waste transmutation blanket (DWTB) for the fusion driven sub-critical system (FDS),the dimension of the FW structure and the shape of helium flow channel have been optimized. The finite element cod e is used to simulate the temperature and stress field of the FW structure. The optimized scheme has been presented under the limit of structure stress and the safety of the structure parts.
