摘要 根据海上核事故核素弥散特点,选择高斯模型进行模拟,基于高斯分段烟羽模型对事故发生后较短时间内的核素弥散情况进行了模拟分析,通过Matlab编程模拟烟羽扩散形式,得出了短时间内事故舰船周围的核素分布情况,从而对受时间和风场影响的核素弥散过程实现了实时烟羽动态模拟。整个核素弥散过程可预报一定时间内核素弥散路径和影响范围,为核救援方案提供参考。 According to the characteristic of nuclide dispersion on the sea, we chose Gaussian model to simulate, and then simulated and analyzed the nuclide dispersion which happened after the nuclear accident in a short time by segmented Gaussian Plume model, and programmed and simulated smoke plume diffusion forms with the software of Matlab. At last, we got the nuclide concentration distribution around the accident ship, thus accomplished the dynamic simulation of nuclide dispersion which affected by time and wind field after the nuclear accident in real time. The whole progress of nuclide dispersion could forecast the nuclide diffusion path and influence scope in a certain time, providing references for nuclear rescue packages.
