Abstract :
The Korean Helium Cooled Ceramic Reflector Test Blanket Module (TBM) consisted of four submodules for International Thermonuclear Experimental Reactor program. The thermal-structural analysis considered a design pressure (10 MPa) and a thermal stress in the changed first wall design, which has a 15 mm × 11 mm rectangular U-shape, was carried out according to the RCC-MR code. The contact stress between the TBM submodules was also evaluated to confirm the structural integrity. The results showed that the design requirements were satisfied.
