建立了一个合理完善的核动力装置蒸汽发生器动态特性分析数学模型，并运用Ｇｅａｒ方法对此模型求解。研制了用于核动力装置蒸汽发生器稳定运行及扰动和事故工况下动态数值模拟的安全分析程序。运用此程序对秦山核电厂蒸汽发生器失去给水的事故进行了计算，所得结果与大型程序ＲＥＬＡＰ－５计算结果符合较好，并对蒸汽发生器几种不同扰动序列的计算结果进行了理论分析。
A reasonable mathematic model of dynamic characteristics analysis of steam generator for nuclear power plant is established and solved by Gear method. A safety analysis program was developed for the steady operation of the steam generator of a nuclear power plant and the dynamic numerical simulation of the disturbance and accident conditions. The program was used to calculate the loss of water supply to the steam generator of Qinshan Nuclear Power Station. The calculated result is in good agreement with the RELAP-5 calculation result of the large-scale code. The results of several different perturbations of the steam generator were analyzed theoretically.
