摘　　要：事故分析是核电厂安全分析的重要组成部分,研究核电厂在故障工况下的行为,是核电厂设计过程和许可证申请程序中的重要步骤。因此对事故工况下核反应堆内放射性物质的释放及其危害进行分析是事故分析的必要内容。分析了放射性物质向主回路系统的释放和向安全壳的释放,分析其释放机理、裂变产物特性、迁移规律和安全壳内的去除措施,介绍了国产安全壳过滤排放装置和除气塔两种去除设备。在核电厂事故释放下,分析附近居民可能受到辐射的主要途径及重要核素的健康特性。Accident analysis is an important component part of nuclear power plant safety analysis. The study of nuclear power plant in accident behavior is the important step in the process of design and the procedure of licence application. So the releasing of active material in the nuclear reactor and their harm were analyzed. Active material releasing to main circuit system and safety shell were analyzed, its releasing principle, characteristics of fissium, transition rule and clear way in the safety shell were studied. The main ways of the occupant were irradiated, characteristic of the important nuclein were analyzed.
