Thermal hydraulic analysis was performed for the 2004 ITER blanket design, whichwas based on the fabrication methods of forging, drilling and welding. Results show that, inthe original design, the flow distribution in radial holes was far from uniform because differentflow drivers were used in the radial holes. Improvement of the flow driver is proposed in thisstudy. With the optimization of the flow drivers, it is clearly shown that the total pressure dropdecreases and a better velocity distribution in radial holes is obtained. The more uniform heattransfer coefficient among the radial holes is beneficial for reducing thermal stress.
