安全壳分析程序以安全壳及其相关厂房为计算对象,采用一维和三维多相多流场模型,主要用于安全壳质能释放分析、最小安全壳压力分析等工作。该程序包括了核电厂安全壳设备模型、水力学现象模型及控制系统模型,具备计算安全壳压力、温度、氢气浓度等关键参数的能力,能够模拟安全壳系统中各类设备的功能,如泵、风机、氢气点火器、氢气复合器、阀门等部件,此外还能模拟大空间内流体的三维流动、喷淋、冷凝、液膜蒸发、氢气燃烧等各类重要现象。
COSINE containment analysis code for simulating the containment and relevant buildings of NPP, adopts one-dimensional and three-dimensional multiphase flow field model. It is mainly used for containment mass energy release and minimum containment pressure analysis. The containment code adopts equipment model, hydraulics phenomenon model and control system model. It can be used for calculating pressure, temperature, and hydrogen concentration in the containment. It can also simulates all kinds of equipment in the containment, such as pumps, fans, hydrogen igniter, hydrogen compound device, valves, etc. The containment code can also simulate all kinds of important phenomenon or process in containment, such as three-dimensional flow of fluid in large space, spray, condensation, liquid film evaporation, hydrogen combustion, etc.
