摘　　要：整体性能试验研究是验证先进非能动压水堆核电站堆芯冷却系统设计有效性的核心技术,一回路系统两相自然循环热工水力特性比例分析是确定整体性能试验装置尺度的主要理论依据。以一维漂移流模型为基础,对整个一回路两相自然循环系统控制方程积分,并求得稳态解,由此获得了系统的流动条件。应用初始流动条件与边界条件,对两相自然循环系统控制方程直接无量纲化,最终得到了整体性能试验装置与实际非能动电站热工水力特性的相似准则。Integral test plays a key role in assessing the performance of the passive core cooling system of the advanced passive nuclear reactor design.The scaling analysis of two-phase natural circulation behavior in primary loop provides the theoretical basis for determining the characteristics scale size of the integral test facility.Based on two-phase drift flow model,a steady-state solution of the flow condition was obtained by integrating the governing equations of the loop two-phase natural circulation.The governing equations were then non-dimensionalized straightway using the initial or boundary condition.Finally,the similarity criteria that should be preserved between the prototype plant and the integral facility was given.
