Abstract

CONTAIN code was used to calculate the hydrogen distribution in the containment of 1000 MW NPP during severe accidents in this article.Two sequences of severe accidents were selected in the system shall be designed to meet the requirement of safety review and to improve the safety of 1000 MW NPP.analysis: the first was large break LOCA in cold leg with ECCS（emergency core cooling system） failure;and the second was SBO with failure of emergency feed pump driven by turbine.The results showed that different hydrogen control requirements are needed for different accidents in various compartments.Hydrogen control
