Design analysis of the China dual-functional lithium lead (DFLL) test blanket module in ITER

摘要

The dual-functional lithium lead-test blanket module (DFLL-TBM) system, which is designated to check and validate the relevant technologies of both the helium-cooled lithium-lead blanket and the helium/lithium-lead dual-cooled blanket for the Chinese fusion DEMO reactor, has been proposed for testing in ITER referring to the relevant several conceptual designs of liquid lithium-lead breeder blankets developed in China. The detailed description of the basic structure, cooling scheme and auxiliary systems for DFLL-TBM has been given in this paper. A series of preliminary performance analyses have been performed to validate the feasibility of the DFLL-TBM design. Preliminary results show that TBM design can satisfy the material requirements and ITER safety design requirements.
