Abstract: [Background] To narrow the gap between international thermonuclear experimental reactor (ITER) and a demonstration reactor (DEMO), a Tokamak device, Chinese fusion engineering test reactor (CFETR) was proposed and is being designed. While the design and discussion of blanket for CFETR is still ongoing. [Purpose] This study aims to present a new conceptual design of a helium cooled solid breeder blanket and to get the results of thermal-hydraulic analysis of the blanket for normal operating conditions. [Methods] The flow characteristic was obtained by theoretical calculation of engineering fluid mechanics and the thermal analysis result was given by fluid-solid coupled finite element analysis using the computational fluid dynamics (CFD) software CFX. [Results] Mass flow rate, mean velocity and pressure drops of coolant in various channels of the blanket were given by the theoretical calculation. Temperature field of the whole blanket module and peak temperature of different functional materials were given by the FEA. [Conclusion] The parameters of coolant are in acceptable range. Rules about temperature limits of different functional materials are followed in normal operating conditions.
