Abstract
An emergency evacuation route is an important component of emergency rescue of for nuclear accidents. A reasonable evacuation route can reduce evacuation times and protect people’s life. The evacuation route of the nuclear power plant is abstracted into a network diagram and a mathematical model of evacuation optimization route based on the graph theory and the parity of spot diagram method in this paper. Road traffic capacity and other external factors that may affect emergency evacuation are considered in the time weight factor for each road. Finally, an example is given to verify the feasibility of the model.
Highlights
The Daiichi Fukushima Disaster, coming 25 years after Chernobyl, emphasized that society must have robust, sensitive emergency management processes to respond to any future radiation accident, international agencies such as the International Commission on Radiation Protection (ICRP) and the International Atomic Energy Agency (IAEA), as well as national government organizations in nuclear countries made a serious of general guidance on nuclear emergency [1]
The National Nuclear Emergency Preparedness Plan [2] is a national plan for nuclear emergency preparedness work in China, which has clearly defined the targets, mechanism, main tasks, and safeguard measures for scientific and technological innovations in the field of nuclear emergency preparedness
The nuclear emergency status is divided into emergency standby, plant emergency, site emergency, and off-site emergency, which correspond to IV, III, II, and I Level Response respectively) in the National Nuclear Emergency Preparedness Plan, according to the accident type, severity, and radiation effects
Summary
The Daiichi Fukushima Disaster, coming 25 years after Chernobyl, emphasized that society must have robust, sensitive emergency management processes to respond to any future radiation accident, international agencies such as the International Commission on Radiation Protection (ICRP) and the International Atomic Energy Agency (IAEA), as well as national government organizations in nuclear countries made a serious of general guidance on nuclear emergency [1]. The Main Objective Method adopted in this paper assumes that the evacuation began before the release of mass radioactive material, and the radiation dosage of the personnel is less than the standard value; the problem of evacuation routing selection is transformed into a single objective optimization. If the sum of the weight of the repeated edges in the loop is less than half of the loop’s total weight, the network model diagram is the optimal network, otherwise the repeating edge is adjusted until the repeated edges in the loop are less than half of the loop’s total weight At this time, the path starts from the origin, and traversal of all of the lines in the diagram (not (6) A loop that contains a repeating edge is randomly selected, and the total weights of the loop are calculated. The virtual origin in the loop is deleted to oSubsttaiinnabtihlitey s2h01o8r,t1e0s,txrFoOuRteP.EER REVIEW
