摘　　要：新开发的非能动安全壳冷却系统(PCS)需要进行试验验证,缩比例试验是一种直接有效的验证方法。本文介绍了PCS综合性能试验台架的比例设计方法、试验台架系统、试验工况。分析了典型试验工况下壳内压力变化情况,气相存在、壳体冷凝换热的无量纲数变化特性,结果表明关键无量纲数处于可接受范围。证明了采用的PCS试验方法的合理、有效,采用该方法设计的台架试验结果可以对原型的物理现象进行准确的相似模拟。Itis necessary to verify the new developed passive containment system, and the small-scale test verification is an effective methodology. Methodology used to design the integral facility of passive containment system, test vessel, auxiliary system, test condition are presented briefly. Non-dimensional numbers of pressure condition, gas exist, and shell condensation heat transfer are analyzed, which indicates the non-dimensional numbers are in the acceptable range. This proves that the adopted methods in the integral test of passive containment system are reasonable and effective, and the test results show that the facility can exactly model the phenomenon of the prototype.
