Overview of design and R&D of solid breeder TBM in China

Testing TBM (Test Blanket Modules) is one of important engineering test objectives in ITER project. China is performing the TBM design and R&D based on Chinese development strategy of fusion DEMO. Helium-cooled test blanket module concept with ceramic breeder for testing on ITER will be one of the basic options in China. The current progress and status on design and R&D of CH HC-SB (Chinese Helium-cooled Solid Breeder) TBM are introduced briefly in this report. The modified designs of HC-SB TBM, related ancillary sub-systems and test strategy on ITER as well as relevant R&D activities are summarized.
