摘　　要：乏燃料后处理厂可能发生临界、放射性物质泄漏、火灾和爆炸等事故,营运单位需要建立相应的应急评价能力,配置针对上述事故的核应急评价系统。本文介绍了针对乏燃料后处理厂5种典型事故的三维可视化实时核应急评价与决策支持系统设计,该系统可基于工艺系统监测数据实现应急工况实时诊断,计算向厂房和环境释放的源项,基于应急预案开展应急响应流程管理,针对工作人员和公众防护策略开展防护行动分析等功能,并基于三维可视化技术实现应急评价结果和响应流程的动态展示。本系统可用于我国乏燃料后处理厂应急评价与决策支持,提升其应急准备与响应能力。A nuclear emergency assessment system should be established to deal with the potential accidents such as criticality,radioactive material leakage,fire and explosion which could occur in spent fuel reprocessing plant.This paper introduces the design of a real-time three-dimensional visualization system for nuclear emergency assessment and decision support for five typical accidents in spent fuel reprocessing plant.The system is capable of diagnosising emergency conditions on real-time based on dynamic process monitoring data,calculating the source terms released into the plant and environment,carrying out emergency response process management based on emergency plan,and implementing protection action analysis for protecting staff and the public.The system can realize the dynamic display of emergency evaluation results and response process based on three-dimensional visualization technology.The system was developed for the emergency assessment and decision support of the spent fuel reprocessing plant,and will improve the emergency preparedness and response capacity.
