Engineering structure design and fabrication process of small sized China helium-cooled solid breeder test blanket module

As partial verification that the original size module of China helium-cooled solid breeder (CH-HCSB) test blanket module (TBM) was reasonable and the development process was feasible, fabrication work of a small sized module was to be carried out targetably. The detailed design and structure analysis of small sized TBM was carried out based on preliminary design work, fabrication process and integrated assembly process was proposed, so it lay a solid foundation for the engineering fabrication of TBM.
