Description

The paper studies the measures 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.
