摘要

摘要: 次临界能源包层是聚变-裂变混合堆的重要部件，对其进行力学特性分析研究是确保整个反应堆正常运行的关键。本文利用有限元分析软件对次临界能源包层的第一壁结构、支撑固定结构的相关零部件开展了初步的力学分析，得到了各零部件相关结构的最大应力值、应力分布云图和变形分布云图，其中支撑结构的最大应力位于加强筋板与圆柱定位销的连接处，应力值为310.2 MPa；第一壁的最大应力位于“U”形流道拐角处，应力值为240.7 MPa；按相应的评价准则进行结构的强度和刚度校核，计算结果表明次临界能源包层各零部件能够满足计算工况下的强度和刚度要求。

Abstract: The subcritical energy blanket is an important component of the fusion-fission hybrid reactor. The mechanical characteristic analysis of the subcritical energy blanket is the key to ensure the normal operation of the whole reactor. In this paper, the preliminary mechanical analysis for the parts including the first wall and the support structure of the subcritical energy blanket is carried out. Accordingly, the maximal stress value, the stress distribution contours and the deformation distribution contours are obtained. The maximal stress of the support structure is located at the connection between the stiffener and the cylindrical pin and the value is 310.2 MPa. The maximal Tresca stress of the first wall is located at the corner of the U shaped flow channel and the value is 240.7 MPa. In the light of the strength and stiffness norms, the calculation results show that the structure of the subcritical energy blanket can satisfy the strength and stiffness requirements.
