摘　　要：为了解决核事故场景难以可视化逼真呈现的难题,结合核应急训练使用需求,通过开展集成化系统架构设计和一系列关键技术攻关,综合采用动态渲染引擎、数字化建模、脚本驱动等三维数字技术手段,开发了一种核应急推演仿真训练系统。该系统能够灵活构设包括235U、239Pu、60Co在内的9种放射性核素材料分别在多种场地条件下发生大面积泄漏、扩散等重大核事故场景,利用后台计算程序量化分析事故造成的辐射水平、影响范围和危害后果并实现态势发展的可视化动态模拟,相关态势数据信息经由局域网交换服务器传递给虚拟训练分系统,引导操作人员按照训练要求执行数字化处置预案,开展辐射监测、污染压制、核材料回收等模拟训练,以虚拟现实交互手段达到沉浸式处置训练的目的。该系统能够为受训人员提供不受气候、地域和环境限制的有效训练环境,为科学开展核应急处置行动提供重要方法途径。In order to solve the problem of difficult visualization and realistic presentation of nuclear accident scenes,combined with the needs of nuclear emergency teams,a nuclear emergency deducing simulation training system was developed by carrying out integrated system architecture design and a series of key technology breakthroughs,and comprehensively using three-dimensional digital technologies such as dynamic rendering engine,digital modeling,and script driving.The system is capable of flexibly constructing nine types of radioactive nuclide materials,including 235U,239Pu,60Co,which undergo large-scale leakage,diffusion,and other major nuclear accident scenarios under various terrain conditions.The system uses backend computing programs to quantitatively analyze the radiation level,impact range,and harmful consequences caused by the accident,and realizes visual dynamic simulation of situation development.Relevant situation data information is transmitted to the virtual training subsystem through a local area network exchange server,guide operators to execute digital disposal plans according to training requirements,conduct simulation training such as radiation detection,pollution suppression,nuclear material recovery and achieve immersive disposal training through virtual reality interaction.This system can provide trainees with an effective training environment that is not limited by weather,geography and environment,also provide important methods for scientific nuclear emergency response actions.
