摘    要:缩小比例的单项和整体性试验台架对研究和开发大型先进压水堆核电站及其分析验证程序都具有重要意义,而由缩比引入的相关现象的失真又直接影响了对台架的设计和试验结果的理解。本文以等效换热系数的形式对非能动安全壳冷却系统(PCS)壳内液膜冷凝在试验台架上的缩比失真进行分析,结合H2TS比例分析方法,系统评价了这种失真对模拟台架中壳内压力响应的作用。结果表明,台架缩比对壳内冷凝液膜换热的影响是保守的。

关 键 词:冷凝液膜传热    失真评价    比例分析    试验台架    非能动安全壳

Abstract:The scale-down separate and integral test facilities are of vital significance for the research and development of both large-scale advanced pressurized water reactor nuclear power plants and the related analytical codes. However, the distortions of some phenomena induced by the reduced size have directly affected both the design of the facility and the understanding of the test results. Through the equivalent heat transfer coefficient, the distortion of condensation film heat transfer on the inner side of PCS was assessed. With the use of H2TS scaling method, the effect of this distortion on the modeling of containment pressure change response was analyzed. The results show that the scale-down of a test facility has a conservative influence on the condensation film heat transfer.
Keywords:condensation film heat transfer  distortion assessment  scaling analysis  test facility  passive containment
