The Research and Development of Operation Support Software for Serious Accidents Simulation

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.
