摘　　要：阐述非能动核电站安全壳外壁冷却水膜稳定性的重要意义,探讨临界水膜厚度和临界空气流速的计算方法及其在非能动核电站中的适用性,并应用水膜脱离模型和表面波模型,探讨维持水膜稳定、避免水膜脱离和水膜破裂的条件,为各种非能动核电站安全壳外壁水膜稳定性的试验研究奠定基础。The importance of the stability of passive falling water film outside containment is discussed.The calculation method of critical film thickness and air velocity and its applicability in passive nuclear power plant are analyzed.With water flooding model and surface wave model,the requirements for keeping water film stable and preventing water film flooding or water film breakdown are discussed,which provides the research foundation for various PCS tests.
