As a part of the design study on Gas cooled Fast Reactor (GFR), core component designs of helium gas cooled fast reactor are being researched. The most promising structural materials of core components have been identified as ceramics, especially Silicon Carbide fiber reinforced Silicon Carbide matrix composites (SiC/SiC) have an encouraging characteristics. However, the existing design factors for Fast Breeder Reactor (FBR) was based on isotropic properties of metal, like a Mises yield criterion. Therefore, the design factors which are considered characteristics of ceramic composites was investigated and refined. The difference of result was compared by FEM analysis. Refined design factors are not only to design core components of GFR but also to indicate an improvement direction of SiC/SiC composites.
