摘　　要：从田湾核电站早期应急的需要,开发了一套核事故场外后果实时评价计算机系统软件(TW-NAOCAS)。该系统设计为一个连接多种模型(数据预处理、风场预测、大气弥散、剂量估算和干预与防护对策评估)和数据库的综合系统。本文对该系统进行介绍,并通过模式比对,对系统物理模型有效性进行了初步分析。结果表明,该系统采用的物理模型和运行设计是有效而可靠的。From the needs of Tianwan NPP＇s early emergency management, a comprehensive nuclear accident consequence assessment system TW-NAOCAS, designed for the real time assessment of nuclear accidental releases from the Tianwan NPP to off-site local scale, has been established through integrating a number of existing preprocessors, wind dispersion, dose evaluation and emergency countermeasure models together with online available meteorology. The results indicate that the development of TW-NAOCAS has been carried out with success through Model J-model intercomparison.
