摘　　要：根据船用压水堆的事故特点,提出采用ESD(事件序列图)方法进行事故序列分析,并以控制棒失控抽出事故为例进行应用研究,建立反应堆不同运行工况下、不同控制棒组(束)失控抽出后装置的动态响应图景,分析过程中考虑了功率调节系统状态、保护系统状态及人员手动干预的影响。结果表明,ESD提供了1种简单的方法来获得船用压水堆的动态事故序列,可以有效帮助运行人员理解反应堆复杂的事故过程。Based on the characteristic of marine PWR accident,the ESD method is adopted to analyze the accident sequence.This paper has studied the uncontrolled draw accident,completed the dynamic response picture on uncontrolled draw accident of NPP different control rod assembly under various operation statea,nd at the time considered the effect of power regulating system,various state of protection system and operator＇s manual control.The result indicates that ESD offers a simple method to obtain the dynamic response picture of marine PWR,which can effectively help operator understand complicated event sequence of PWR.
