摘要
The China home team is developing an ITER TBM based on a helium-cooled solid breeder （HCSB） DEMO blanket concept . This blanket concept employs high-pressure helium （8 MPa） to cool down the blanket first wall （FW） and side wall （SW） structures and the interior of the blanket module, including the beryllium multiplier pebble beds and the Li4SiO4 breeder pebble beds （enriched lithium-6 of 80%）. The tritium breeder is purged by forced flow low-pressure helium （0.1 MPa） provided by the tritium extraction system （TES）. Low activation ferritic/martensitic steel is selected as the structural material for the TBM.
