Numerical Simulation and Analysis of Thermal-Hydraulic Characteristics of the First Wall in Dual-cooled Waste Transmutation Blanket
Analysis has been carried out using CFX software on the thermal-hydraulic characteristics of the water-cooled first wall of Dual-cooled Waste Transmutation Blanket(DWTB) in Fusion Driven Subcritical system(FDS). A partial model of the first wall is established. Then the model is calculated with water under typical operational condition of PWR as coolant, with the coupling of heat transfers between solid and fluid being considered. The calculation shows that when the inlet speed of water ranges from 1m/s to 5m/s, maximum temperature of the structure is 16K to 91K lower than when the structured is cooled by helium under typical operational conditions, difference between maximum and minimum temperature of the structure is also 12.2％ to 49.5％ lower. The results show that the water-cooled system can meet the thermal-hydraulic requirements of the first wall under steady-state conditions.
