The article introduces the method of level 2 probabilistic safety assessment in multiple external hazards compound situations, and the application of probabilistic safety assessment technology in building a Level 2 probabilistic safety assessment model for a domestic nuclear power plant under such circumstances. This model can be used to quantitatively evaluate important risk indicators like the frequency of a large release of radionuclides, frequency of occurrence of each release category, in order to identify weaknesses of nuclear power plants in responding to risks. Corresponding risk insights are provided to enhance the safety of nuclear power plants.
