Numerical simulation of the temperature field in the ITER Chinese helium cooled solid breeder test blanket module

Two and three dimensional temperature fields in the Chinese helium cooled solid breeder test blanket module(CH HCSB TBM) used in the international thermonuclear experimental reactor(ITER) were simulated using the general-purpose computational fluid dynamics code Fluent.Temperature distributions were given for the Be armor,the Be pebble bed,the Li_4SiO_4 pebble bed,the TBM structural material,and the helium coolant in the cooling pipe.The results show that the temperatures in each material are below the allowed material work temperatures and that the two dimensional results agree reasonably well with the three dimensional results.The analysis can be used to further optimize the thermal hydraulic design of the breeder blanket module.
