| 摘 要： | 在一维质量、动量和能量守恒方程基础上建立了AP1000反应堆主冷却剂系统及非能动余热排出系统数学模型，并编制了用于该系统瞬态特性分析的动态仿真程序PRHRSDSC。模拟了非能动余热排出系统在全厂断电事故下的瞬态响应过程，并将计算结果与西屋公司的LOFTRAN程序结果进行对比。结果表明：系统可依靠自然循环有效导出堆芯余热，一回路冷却剂温度维持在过冷状态，峰值压力未超过运行压力限值，各参数的变化趋势符合良好，证明了建模的合理性。

| Abstract: | Based on one-dimensional governing equations, the mathematical models of the reactor primary coolant system and the passive residual heat removal system (PRHRS) were established. A dynamic simulation program PRHRSDSC was developed to analyze the transient characteristics of the system. The program was used to simulate the transient process of PRHRS during station blackout accident. The calculated results were compared with LOFTRAN code. The results show that the core residual heat can be removed efficiently using natural circulation to keep the coolant at sub-cooled state and the peak pressure is below the limit of the operation pressure. The parameter variation trends are well consistent with LOFTRAN code and the rationality of the model is demonstrated. |
