Progress and status of Chinese helium-cooled solid breeder TBM

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