In the containment analysis of nuclear power plant, containment scaling analysis could be used to confirm the important phenomena of containment cooling system and demonstrate the sufficiency of test data. Based on the design basis accident (DBA) of passive nuclcar power plant, the scaling analysis method was used to quantify the effect of heat and mass transfer characteristic of liquid drop to mass, energy and RPC. The effect of containment cooling system phenomena to containment pressure response can be confirmed by this scaling analysis.%在核电厂的安全壳分析中,安全壳比例分析可用于安全壳冷却系统重要现象的确定和试验数据充分性的论证.本文以非能动核电厂为例,应用比例分析方法对安全壳内液滴进行传热传质特性分析,量化了核电厂液滴的传热传质特性对质量、能量和压力变化率(RPC)的影响.通过本比例分析,可确定具体安全壳冷却系统对安全壳压力响应的影响程度.
