The finite element analysis and calculation were performed for the blanket first-wallmade of SiC/SiC composite material for Advanced Steady-state Tokamak Reactor 2, A-SSTR2,which at present is conceptually designed in Naka Fusion research establishment, JAERI. Compar-ison analysis and design window were analyzed using the finite element code ADINA 7.4. Througha 2D calculation for various geometrical configurations and sensitive material properties, a fun-damental guideline for the first wall and blanket design are established with respect to maximumtemperature, thermal and mechanical stress for many configurations. To satisfy hydrodynamicrequirement, a4d4 (the dimension of coolant channel is 4 mm × 8 mm, and the distance betweenneighboring channels is 4 mm) was chosen as a design point for high thermal conductivity upto 50 W/m.K. In order to find a good solution for lower conductivity, more elaborate work shouldbe done in the future. Nonetheless, the outline of design window for a specific structural materialis very useful for the future A-SSTR2 first wall design.
