After the nuclear accident, the effective evacuation of personnel in the field is an important guarantee for nuclear safety. Combined with the characteristics of the nuclear facility area and the actual evacuation of the personnel, this paper constructs the failure model of the emergency evacuation network in the nuclear accident field, and simulates the cascade failure process and the influence degree of each node in the network. Through the simulation results and analysis, the specific suggestions are put forward from the aspects of the construction of the facilities and the determination of...
