Design and Realization of Water Distribution Experiment System for High-power Pressurized Water Reactor PCS

  • 摘要: 针对大功率非能动安全壳基准事故下的水流特征,采用和原型安全壳相同尺寸比例及切片形式,设计了椭球扇面试验台架装置和相应的测量系统以研究安全壳穹顶水膜覆盖率和延迟时间等关键参数与冷却水流量之间的关系。同时开发了大空间曲率表面的视频测量系统,通过电容探针及其三维可调节支架系统实现了本体各处的水膜厚度非接触式测量,并对关键测量系统进行了标定。初步分析结果表明,试验本体及回路设计合理可行,获得了水膜覆盖率和相对延迟时间随雷诺数的变化关系。

     

    Abstract: Aimed at the water flow characteristic under design basis accident (DBA) for high-power pressurized water reactor passive containment cooling system, a full scale but sector style of the containment was adopted. In order to study the relationship between the flow rate and the key parameters such as water film coverage rate, quasi-steady time etc., an ellipsoid sector test facility and respective measurement system were designed. A high-speed image measurement system for large curvature surfaces was also designed. The water film thickness measurement system was designed to obtain the accurate film thickness data by non-contact electric capacitance probes and related three-dimensional adjustable bracket system. All the important measurement systems were calibrated. Preliminary analysis results show that the design of test body and loop is reasonable. The trends of water film coverage rate and the relative quasi-steady time with different Reynolds numbers are obtained.
