Abstract

serious accidents in nuclear power plants (npps) may cause environmental radioactive contamination, resulting in significant social negative effects. The research of serious accidents in npps is gaining increasing concern. The operation support software for serious accident simulation is consists of real-time monitoring, intelligent SAMG and forecast analysis module. The main technologies of real-time intervention in the process of serious accident analysis and dynamic generation for guided SAMG are described in the paper. Last but not least, taking Fangjiashan NO.1 power plant as the research object, then a serious accident of SBO with LOCA and restore power is calculated by software, and Judged whether the main parameters of the system are consistent with the changes of major characteristics in the process of serious accidents. The results show that the software is reasonable in calculation, stable in operation and convenient in graphical interface operation. It is in line with the use habit of serious accident management personnel in npps, and can provide technical support for the operation of nuclear power plants.

重大事故模拟运行支持软件的研究与开发

核电站发生重大事故，可能造成环境放射性污染，造成重大的社会负面影响。核电站重大事故的研究日益受到人们的关注。重大事故模拟运行支持软件由实时监测、智能SAMG和预测分析模块组成。介绍了引导式SAMG重大事故分析过程实时干预和动态生成的主要技术。最后，以方家山第一电厂为研究对象，对一起严重事故的SBO进行LOCA和恢复功率的软件计算，判断系统主要参数是否符合严重事故发生过程中主要特征的变化。结果表明，该软件计算合理，运行稳定，图形界面操作方便。符合核电厂重大事故管理人员的使用习惯，可以为核电厂的运行提供技术支持。
