Abstract
Preliminary design and analysis for China helium-cooled solid breeder （CH HC-SB） test blanket module （TBM） for testing in ITER（ International Thermonuclear Experimental Reactor） device have been carried out recently. In this paper, the design description, the performance analysis and the related ancillary systems for CH TBM are introduced. The key features of the design are based upon the breederoutside-tube （BOT） concept, on the use of solid breeder ceramic material, of helium as coolant and tritium purge gas, of ferrite-martensite steel as structural material, and of beryllium as neutron multiplier. Results show that the proposed TBM concept has the advantages of higher tritium breeding ratio （TBR）, simple structure design and engineering feasibility.
