液钠冷却池式快中子增殖反应堆(简称快堆)主容器壳附近设置有径向薄壁热屏蔽围堰。快堆运行时少部分冷钠通过热屏蔽围堰和主容器壳间的间隙从下向上流动,当液面高度高于围堰上沿时发生溢流,液钠沿围堰内壁面流入冷钠池。为研究溢流时薄壁结构与流体间相互运动引起的流体弹
Liquid sodium-cooled fast reactor neutron breeder reactor (Reactor) near the main container shell is provided with a radial thin-walled heat shield cofferdam. During the operation of the fast reactor, a small amount of cold sodium flows through the gaps between the heat shield cofferdam and the main container shell from the bottom to the top. When the liquid level is higher than the upper edge of the cofferdam, liquid sodium overflows into the sodium silicate along the inner wall of the cofferdam Pool. In order to study the fluid bomb caused by the mutual movement of thin-walled structure and fluid during overflow
