Abstract: The emergency road of nuclear power plant has always been the focus of the site emergency evacuation feasibility analysis. The probabilistic risk assessment method is applied to the emergency evacuation simulation of nuclear power plants in this paper. Using self-designed simplified evacuation simulation program, combined with the site characteristics of accident source term, population, road and meteorological conditions, the possible exposure doses to the public and staff under emergency conditions of multiple nuclear power plant sites are calculated, and the risks of each site are compared. Besides, combined with the practical problems encountered in the emergency evacuation road scheme of Xiapu site, while ensuring the effective evacuation of the public and staff under emergency conditions, the schemes of emergency evacuation road are compared and selected in combination with the actual situation of the plant site, which could provide reference for the implementation of the Xiapu project. The program and the method mentioned above can also provide technical support for the subsequent development of island nuclear power plant and small heating reactor, which is also conducive to more intuitive public communication of nuclear power.

Key words: emergency evacuation, probabilistic risk assessment, emergency feasibility analysis
