基于压水堆二回路热力系统热经济性定量分析理论,提出适用于M310核电机组的二回路热力系统变动后机组反应堆安全性分析计算方法。应用该方法对M310机组二回路两列高压加热器解列的事故工况进行了反应堆安全性分析计算,并与全范围模拟机的仿真结果进行比较,结果一致,说明本文提出的反应堆安全性分析计算方法是正确且准确的。
Based on the quantitative analysis theory of thermal economy of the thermodynamic system of the second circuit of PWR, the safety analysis and calculation method for the unit reactor after the change of the thermodynamic system of the secondary circuit of M310 nuclear power plant is proposed. This method was used to analyze the safety of the reactor in the accident conditions of two columns of high pressure heaters in the second circuit of M310 unit and compared with the simulation results of the full range simulator. The results are consistent. The analysis of reactor safety proposed in this paper The calculation method is correct and accurate.
