福清核电厂应急撤离时间估算

本文介绍了环境保护部核与辐射安全中心主持开发的“核电周边人员应急撤离的虚拟现实模拟系统”(简称“撤离模拟系统”)及所采用的技术。结合福清核电厂厂址周围的人口分布、交通基础设施分布和天气状况,利用该系统模拟了不同撤离情景下,福清核电厂烟羽应急计划区内人员的撤离过程,估算了撤离时间,分析了影响撤离的主要因素。研究结果表明,福清核电厂在典型事故情景下,部分拥堵路段对撤离时间影响显著;同时,私家车的使用比例增加也会显著增加撤离时间。

Evacuation time estimation (ETE) in case of an emergency at Fuqing nuclear power plant

A system of virtue reality simulation on emergency evacuation around nuclear power plant is described.We simulated the evacuation process under different scenarios through modeling the influences of population distribution,human behavior,traffic infrastructure and weather condition of the Fuqing nuclear power plant.Major influencing factors on evacuation time were analyzed using the evacuation simulation system.The results indicated that congested roads play an important role in emergency evacuation time under typical accident scenarios.Meanwhile,the increasing fraction of private car usage would also increase the evacuation time.
