基于C4ISRE系统的核电站大气核污染扩散轨迹系统仿真研究

为了在核污染事故处理时提供精细化预警，以辽宁省某核电站周边部分重要目标（大衣屯、大周屯、红沿河镇、驼山乡、西杨乡、复大线应急撤离线路）为研究对象，将环境保护指挥自动化系统C4ISRE（Command，Control，Communications，Computer，Intelligence，Surveillance，Reconnaissance，Environmental Impact Assessment）与HYSPLIT 4.9模型相耦合，采用NCEP（美国国家环境预报中心）的FNL全球气象数据对核污染扩散轨迹进行仿真研究.结果表明:自模拟初始时间2014-04-01T00:00:00.00开始，进、出大衣屯边界时间分别为00:06:16.560、00:06:49.000，历时31.340 s；由西向东横穿过大周屯，进、出时间分别为于00:06:16.56到达大衣屯北部边界，于00:06:46.90扩散出大衣屯边界，经过大衣屯区域耗时共计29.00 s；核污染气团于00:15:30.85到达大周屯上空500 m处，由西向东横穿过大周屯，于00:15:46.05离开大周屯上空，过程耗时15.20 s；核污染气团于00:32:14.25经过重要应急撤离线路2（复大线），全程耗时32 min 14.25 s.核污染气团与从2014-04-01T00:00:00.000进入红沿河镇上空500 m区域，于00:24:27.00扩散出，全程历时24 min 27.00 s；进、出驼山乡上空500 m区域的时间分别为00:24:28、00:51:00，历时26 min 32.00 s；进、出西杨乡上空的时间分别为00:51:01、01:05:4.70，历时14 min 37.00 s；重点区域大衣屯和大周屯行政区的预警时间分别为376.56、930.85 s，重点撤离线路2区域预警时间为1934.25 s. 

Systematic Simulation of Atmospheric Nuclear Pollution Diffusion Trajectory of a Nuclear Power Plant based on C4ISRE

Abstract: When dealing with nuclear pollution accidents, it is necessary to the refine the early warning technique to support joint defense action. For locations including Dayi village, Dazhou village, Hongyanhe town, Tuoshan village, Xiyang village and Fuda line emergency evacuation route, precise emergency warnings for atmospheric nuclear pollutant transport trajectories were determined based on C4ISRE (Command, Control, Communications, Computer, Intelligence, Surveillance, Reconnaissance and Environmental Impact Assessment) and HYSPLIT 4.9 model, which was driven by FNL meteorological data from NCEP. The results showed that a nuclear pollution air mass spread into the northern border of Dayitun between 00:00:00.00 and 00:06:16.56 on April 1. It then moved outside the border of Dayitun at 00:06:46.900, taking only 29.00 seconds to shift. It arrived in the airspace of Dazhou village (altitude of 500 m) at 00:15:30.85, traversing Dazhou village from west to east. It left the airspace of Dazhou village at 00:15:46.05, taking 15.20 seconds. It then arrived in the airspace of vital emergency evacuation route 2 (Fuda route) at 00:32:14.250, taking 32 minutes and 14.25 seconds. Next, it spread into the airspace of Hongyanhe (altitude of 500 m) at 00:00:00.00 on April 1,4. Then, it spread away from Hongyanhe at 00:24:27.00, taking 24 minutes and 27.00 seconds. It arrived in the airspace of Tuoshan township at 00:24:28.00, spreading away from the area at 00:51:00.00, which took 26 minutes and 32.00 seconds. It arrived in the airspace of Xiyang township at 00:51:01.00, spreading away from the area at 01:05:04.70, which took 14 minutes and 37.00 seconds. The early warning and emergency response times for relevant areas were as follows:Dayi village administrative region was 376.56 seconds, Dazhou village administrative region was 931.85 seconds, and emergency evacuation route 2 was 1934.25 seconds.
