Abstract
After Conceptual Design (CD) Approval by ITER orgnization, Chinese Helium Cooled Ceramic Breeder (HCCB) Test Blanket Module (TBM) design has been updated during the preliminary design phase, in which the manufacturability was the main concerned issue. The main components design such as the back manifold zone, the rib&cap, and the breeding zone were updated through the neutronic, thermal, structural and hydraulic analyses with MCNP and ANSYS. The flow diagram of the He coolant and purge gas in TBM was optimized, which can satisfy the heat remove need of TBM. Different materials’ temperature and stresses were well below the limit. The design of the associated TBM shield was also updated in order to simplify production and assembly.
