摘要
对非能动安全冷却系统热工、水力机理进行了研究,着重对钢安全壳内外混合气体传热和流动模型、钢安全壳外表面液膜模型、非能动贮水箱模型以及紊流模型和辅射换热模型等进行了分析研究。并运用自主开发的PCCSAC-3D程序对先进堆冷段双端断裂大破口失水事故工况下的安全壳压力和温度进行了计算分析。
Mechanism of hydraulic and heat transfer of Passive containment vessel cooling system is studied.Heat transfer and flow model of gas mixture in and out steel containment vessel, fluid film model outside surface of steel containment vessel, passive storage tank model, turbulence model and heat transfer model by radiation are emphasize analytical studied. Taking advantage of PCCSAC 3D Code that is developed by self-determination, the pressure and temperature in the advance PWR containment vessel is calculated and analyzed under cold leg double end rupture large crevasse loss-of-coolant accident.
