摘要：

The radioactive source term analysis of serious accidents in nuclear power plants is the focus of attention in the field of nuclear safety, and the source term analysis has great uncertainty. In this paper, based on the best estimate plus uncertainty (BEPU) analysis method, HPR1000 serious accident analysis model is established by using the integrated serious accident analysis program. For the first time, from the point of view of the whole accident process, a process suitable for source term uncertainty analysis of HPR1000 serious accident is developed, and this method is used to analyze the source term uncertainty of containment bypass release category. The research content of this paper enriches the source term analysis of the serious accident of HPR1000, and also lays a foundation for the development of the three-level probabilistic safety analysis (PSA) technology of HPR1000. © 2022 Yuan Zi Neng Chuban She.
