摘　　要：本文应用RELAP5程序进行AP1000核电厂典型的运行瞬态分析,该分析模拟核电厂主要的控制系统,包括反应堆功率控制、反应堆快速降功率、稳压器压力控制、稳压器液位控制、蒸汽发生器液位-给水控制以及主蒸汽旁排控制系统等,验证在预期运行瞬态下核电厂依靠控制系统就可达到安全稳定状态,而不触发保护系统动作。计算结果与美国西屋分析结果基本吻合,表明AP1000核电厂运行瞬态响应可满足相关设计准则的要求。Typical operational transients have been analyzed with RELAP5 code for AP1000 NPP, in which the reactor power control system was simulated, including Reactor Control System （RECS）, Rapid Power Reduction （RPR）, Steam Dump Control System （SDCS）, Feedwater Control System （FWCS）, Pressurizer Pressure Control System （PPCS） and Pressurizer Level Control System （PLCS）. It indicates that the plant control system is effective to bring the plant into a safe steady state without actuation of reactor protection system under the representative operational transient, only depends upon the plant control system adjustment. Analysis results show that the design requirement will be met for AP1000 operational transient.
