摘　　要：CAP1400是我国自主开发的第三代非能动核电站。为了验证CAP1400反应堆水力设计的合理性,有必要开展整体水力模拟试验。在整体水力模拟试验中,试验件比例分析和简化是试验开展的基础。从模型比例、模型相似关系和模型简化设计等方面介绍了模型试验件的设计。对模型比例主要考虑因素、比例模型遵守的相似关系及主要模拟试验的试验件简化设计进行了详细地描述。试验件的简化不仅能降低模拟试验的制造成本,而且能反映CAP1400反应堆内冷却剂的实际流动状态。CAP1400 reactor is the third generation advanced passive PWR reactor which is designd by china, it is necessary to carry out the reactor hydraulic simulation test for verifying the rationality of hy- draulic performance of CAP1400 reactor internals. Scale analysis and model simplification are the base of hydraulic simulation test. This paper describes in detail the main factors of model scale, similarity criterion and the simplification of test model. The simplification of model will not only reduce the fabrication cost, but also can simulate the real flow pattern in the CAP1400 reactor.
