摘　　要：基于国际热核聚变实验反应堆磁约束聚变-裂变混合能源系统次临界包层的物理-热工设计结果,提出了聚变-裂变混合堆次临界包层燃料区结构设计方案,包括纵骨支撑结构、燃料区结构和锆包壳结构。运用Pro/e建模软件建立了次临界包层燃料区结构模型,并利用ANSYS-workbench mechanical有限元分析软件对纵骨式支撑结构开展了初步力学分析,得到了燃料部件和纵骨式多层支撑结构的最大Tresca应力值、应力分布云图和总变形量,其中最大应力为87.04 MPa,最大变形量为0.17mm。按照第3强度理论校核,计算结果表明纵骨式次临界包层结构各部件能够满足强度要求。Based on the result of physics and pyrology design,the design of subcritical blanket fission fuel zone structure is given for the fusion-fission hybrid reactor.This scheme includes longitudinal bone support structure,fuel zone structure and zirconium cladding structure.Using Pro/e CAD software,the subcritical blanket fuel zone structure model is established,at the same time,the preliminary mechanical analysis for the longitudinal bone style support structure is carried out by ANSYS-workbench mechanical finite software.Accordingly,the maximal Tresca stress value,the stress distribution contours and the total deformation are obtained,the maximal stress and deformation are respectively 87.04 MPa and 0.17 mm.In the light of the third strength theory,the above calculation results show that the longitudinal bone style subcritical blanket fuel zone structure can satisfy the strength requirements.
