The hydraulic simulation of the water-cooled blanket module based on Fluent code is reported. This study focused on heat transfer and the pressure drop under the sub-critical water condition. The temperature field distribution is discussed with the solid zones (breeder, multiplier and F82H material) and the coolants. The peak temperature of beryllium zones reaches about 600 degrees C and most of the breeder zones (Li(4)SiO(4), Li(4)SiO(4)/Be(12)Ti) would be nearly 900 degrees C, which meets the thermal design requirements of the blanket material. For the Delta P (pressure drop), the piping circuit assumes most of the Delta P (72.68%) comparing to the other two, the FW (first wall) channel (23.96%) and the header (3.36%), and the total Delta P of blanket cooling system would be under 0.5 MPa which could be satisfied with the design guideline. In addition, by comparing on Delta P between the simulation and the empirical results, it is confirmed the empirical rules of Delta P could be applied to estimate the preliminary values of Delta P on relevant cooling structure.
