Description
After the Conceptual Design Review (CDR), Helium Cooled Ceramic Reflector (HCCR) Test Blanket Module (TBM) is in progress of the preliminary design phase. The detained design work was performed on the connecting supports which are connected between the TBM and the TBM-shield. The geometric design of the connecting supports are referred from the connection design of the blanket first wall. The other types of design are H-beam and a flanged connection which are typically used in the industry. These connection types are based on the bolted joint. The thermo-mechanical analysis was performed characteristics of connecting support types according to the material and the loads conditions. The TBM is designed to make of a RAFM (a reduced activation ferritic-martensitics steel) while the material of TBM-shield is 316L(N)-IG. The material of the connecting support should be considered due the different thermal expansion. The concentrated stress would be generated on the dissimilar welded contact region. The pretention load on the bolted joint is major factor to determine the stress distribution on the connecting support at the specific loads condition. The design modification is continued to meet the design requirement in all loads conditions.
