摘　　要：本文应用RELAP5程序模拟AP1000核电厂阶跃升负荷运行瞬态工况并进行分析。该分析模拟了反应堆功率控制系统，以验证核电厂在预期运行瞬态下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。分析结果表明：核电厂瞬态响应满足设计准则的要求。Typical step load increase operational transients have been analyzed with RELAP5 code for AP1000 NPP, in which the reactor power control system was simulated. 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 transien4 only depends upon the plant control system adjustment. Analysis results show that the design requirement will be met for AP1000 operational transient.
