摘　　要：AP1000核电给水流量丧失事故下避免稳压器满水措施的研究,主要目的是掌握导致稳压器满水的主要影响因素,建立这一事故的分析方法,既考虑基于现有手段(压力容器封头排气系统)提出应对策略,又根据分析结果提出改进措施(增大非能动余热排出系统排热能力),供技术决策层参考。The paper studies the meastures to prevent the pressurizer from filling up with water on condition of the loss of normal feedwater accident. The main aim of the study is to get knowledge about the factors causing the pressurizer filling up with water, and to creates the analysis method for the accident. Finally, the paper puts forward counter measures based on the existing reactor vessel head ventilation system, and also the design optimization to increase the capability of the passive residual heat removal system.
