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 results of physical-thermal design of sub-critical cladding in ITER fusion fission-hybrid energy system, a design scheme of sub-critical cladding fuel zone for fusion-fission hybrid reactor was proposed, including the longitudinal support structure, Fuel zone structure and zirconium cladding structure. Pro / e modeling software was used to establish the sub-critical cladding fuel zone structure model, and the use of ANSYS-workbench mechanical finite element analysis software to carry out the initial mechanical analysis of the longitudinal bone support structure has been fuel components and longitudinal multi-layer The maximum Tresca stress, the stress distribution cloud and the total deformation of the supporting structure, of which the maximum stress is 87.04 MPa and the maximum deformation is 0.17 mm. According to the third strength theory check, the calculation results show that the longitudinal bone sub-critical cladding structure components to meet the strength requirements.
