Thermo-hydraulic and neutronics calculation for the blanket of HCSB-DEMO

Through thermo-hydraulic and neutronics iterative computation and optimization for the blanket sub-module on HCSB-DEMO,the preliminary structure layout under separate cooling circumstance has been designed,which meet several important requirements from thermo-hydraulics and neutronics.Each material's temperature is below its limit value,outlet temperature of coolant has reached 500℃,and pressure drop of coolant has also meet the engineering requirement,meantime TBR has reached 1.30,regardless of the complicated structures.Using the final structure layout mentioned above,there were still some discussions about the sympathetic cooling circumstance,considering that the first wall is a special component with high heat flux,it is suggested that separate cooling circumstance should be taken.
