Abstract

Abstract

Flow behavior of coolant in natural circulation reactor was analyzed by CFD.The analysis found that the results of flow field calculated by SST and SSG turbulence models are basically same,and the results of flowrate calculated by CFD and Relap5 are also basically same.From CFD calculations,the flow distributions were symmetrical at the lower plate,which showed that the minimal mass flow factor was 0.93.Flow distributions could be adjusted by closed core channels and chimneys,which gave the better results.
