Thermo-mechanical assessment of the optimized CFETR water cooled ceramic breeder blanket

Within the framework of the engineering design of CFETR, an updated design of WCCB blanket was proposed corresponding to the latest core parameters (major radius=7.2 m, minus radius=2.2 m). Thermalhydraulic analyses preliminarily showed the feasibility of the previous blanket design.

However, the flow distribution of the blanket was unsatisfactory. Thus, optimization of cooling systems of the blanket was performed accordingly. The optimized blanket design as well as the hydraulic analysis results are presented.
