【摘要】：基于环境保护指挥自动化系统C4ISRE,提出了核电站大气核污染扩散预警方法.首先,构建红沿河核电站"海/陆/空/天一体化"仿真环境.其次,根据核污染扩散想定应用气象数据驱动HYSPLIT4.9模型,模拟大气核污染物输送特征,进而推演模拟各个重点区域的预警应急处置时间.推演结果表明:核污染扩散气团经过71.885 s到达常规岛废液贮存罐厂房;79.306 s扩散至热机修车间和仓库;91.596 s抵达废水处理站和车库;132.267 s扩散至厂界海区边界;655.337 s扩散至烟羽应急区5 km边界;712 s进入黄泥洞村空界;1 240.535 s扩散至烟羽应急区10 km边界;2 527.945 s扩散至长兴岛镇空界;3 468.65 s扩展至烟羽应急区30 km边界.
[Abstract]:Based on C4ISRE-based command automation system for environmental protection, an early warning method for atmospheric nuclear pollution diffusion in nuclear power plants is proposed. Firstly, the "sea / land / air / sky integration" simulation environment for the Hongyan River nuclear power station is constructed. Secondly, according to the nuclear pollution diffusion scenario, the HYSPLIT4.9 model is driven by meteorological data, which simulates the transport characteristics of atmospheric nuclear pollutants, and then deduces and simulates the early warning and emergency disposal time of each key area. The results show that after 71.885 s, the nuclear pollution diffusion air mass reached the conventional island waste liquid storage tank factory building for 79.306 s and reached the waste water treatment station and garage for 91.596 s to reach the waste water treatment station and the garage to the boundary area of the plant area at 655.337s. From the 5 km boundary of Yanyu emergency area, 712 s into Huangnidong Village air boundary 1 240.535 s, to 10 km boundary 2 527.945 s spread to Changxing Island town air boundary 3 468.65 s to extend to 30 km boundary of Yanyu emergency zone.
