堆芯流量分配特性是自然循环铅基快堆热工水力设计的重要内容,一回路腔室几何结构是影响堆芯流量分配特性的重要因素之一。利用计算流体力学方法(Computational Fluid Dynamics,CFD)模拟小型模块化自然循环铅冷快堆(Small Modular Natural Circulation Lead-cooled Fast Reactor-10 MW,SNCLFR-10)一回路流场,分别研究一回路上腔室提升筒高度、中心测量柱半径及长度,下腔室深度、纵横比以及导流结构高度对堆芯流量分配特性的影响特性。研究结果表明:改变提升筒高度、中心测量柱半径及长度对堆芯流量分配特性影响较大;改变反应堆下腔室深度和下腔室纵横比对堆芯整体流量和流量分配特性所造成的影响...

[Background] The flow distribution characteristic of core is an important consideration in the design of natural circulation lead-based fast reactor. The primary chamber geometry is one of the important factors affecting the flow distribution characteristic of core. [Purpose] This study aims to investigate the effects of the height of the chamber riser, the radius and length of the central measuring column, the depth of the lower chamber, the aspect ratio and the height of the diversion structure on the flow distribution characteristics of the ...
