蒸汽发生器给水瞬变事故的研究

Study on the water feed transient accident of the steam generator

通过对蒸汽发生器流量、水位以及一回路相应温度、功率等参数的计算,模拟蒸汽发生器给水流量发生瞬变时的动态过程。建立准确的数学物理模型,该模型可以与其它船用模型结合以进行安全分析研究或为运行操纵人员提供可靠的分析依据以及相应的问题解决方案。

The authors calculated the water supply, water position, temperature, and the power of the primary circuit in the steam generator to simulate the dynamic process when the water supply changes suddenly. The mathematical physical models are precisely established, which can be used for the safety analysis together with other marine nuclear power models. The result can provide us reliable analytical basis and the method to solve the problem.
