Abstract: A new type of subcritical energy blanket for fusion fission hybrid reactor was introduced. A 3D finite element model (FEM) of the blanket was established with ANSYS Workbench. The steady-state thermal analysis and thermal-mechanical coupling analysis of the model were carried out. The stress and deformation distributions of all parts of the blanket were obtained. The strength and stiffness of all parts of the blanket were analyzed. The weak position of the blanket was found by the thermal-mechanical coupling analysis. The results show that the strength and stiffness of the blanket meet the requirements. It provides a theoretical basis for the design and improvement of the new subcritical energy blanket.
