Water is chosen as the fluid. The experimentalresults are compared and analyzed carefully. The complex flow velocity distribution is ob-tained in the experiment with each core structure. The conclusion that the improved upperplenum core structure can reduce the hydraulic load on the drop of cootrol rods is drawn.展开更多
