核电厂应急撤离时间量化评估方法研究
Quantitative assessment methodology for emergency evacuation time in nuclear power plants
摘要
Abstract
This study addresses the potential risk of large-scale airborne radioactive material leakage and dispersion resulting from severe accidents at nuclear power plants.A hypothetical accident simulation is conducted for the Hongyanhe Nuclear Power Plant to calculate and evaluate evacuation times during off-site emergency responses.In line with the"one plant,one plan"principle,this research integrates local human geography information surround-ing the plant,selects gathering points within the emergency planning zone,and determines off-site relocation points for evacuation.Evacuation routes are designed and assessed using Dijkstra's algorithm,whereas the HYSPLIT mod-el is employed to simulate the dispersion of radioactive material from an incident at the Hongyanhe Nuclear Power Plant.This simulation analyzes the dispersion trajectory,ground deposition,and near-ground diffusion of airborne radioactive substances.Based on these simulations and considering typical weather conditions and road traffic ca-pacity in the Hongyanhe area,the maximum emergency evacuation time is calculated to be 176.2 min,with a pub-lic exposure dose of 32.06 μSv.This study provides valuable insights for government organizers to optimize emer-gency evacuation strategies during nuclear accident scenarios.关键词
