U形管蒸汽发生器模型及动态仿真

U-tube Steam Generator Model and Dynamic Simulation

针对核电站立式U形管自然循环蒸汽发生器,建立了能够描述其稳态及瞬态热工水力特性的数学物理模型,并编制了计算程序。计算和验证结果表明,该数学物理模型准确,可以与其它核电站模型一起构建核电站系统模型以进行安全分析研究或开发核电站仿真机。

For the vertical U-tube natural circulation steam generator in nuclear power plant, the mathematical physical models and calculating code to predicate the thermal hydraulic behaviour are established. The calculational results show that the mathematical physical models are accurate, and the model can be used to safety analysis and development of nuclear equipment simulator together with other nuclear power models.
