Current progress of Chinese HCCB TBM program

Highlights: • China plan to test own test blanket modules (TBM) during ITER different operation phase (H-H,D-D, D-T). • A preliminary design (PD) of HCCB TBM have being performed since 2014. • In order to reduce the effects of magnetic field ripple, the HCCB TBM design has been updated with reduced RAFM mass. • Related R&D on key components fabrication, welding technology, materials development, He test loop constraction and mock-up test of TBM modules and components have being implemented. • The current status on design and related R&D, as well as the development of auxiliary system (TES, CPS,HCS, etc.,) of Chinese HCCB TBS program ware overviewed. - Abstract: ITER is an unique opportunity to test tritium breeding blanket mock-ups in integrated Tokamak operating conditions. Helium-cooled ceramic breeder (HCCB) test blanket module will be the primary option of the Chinese ITER TBM program. China plans to test its own test blanket modules (TBM) during ITER different operation phase (H-H,D-D, D-T). A preliminary design of HCCB TBM have been completed in 2013. In order to reduce the effects of magnetic field ripple, the HCCB TBM design has been updated with reduced RAFM mass recently. Related R&D on key components fabrication, welding technology, materials development and mock-up test of TBM modules and components have being implemented. In this paper, the current status on design and related R&D, as well as the development of auxiliary system (TES, CPS,HCS, etc.,) of Chinese HCCB TBS program were introduced.
