A review on radionuclides atmospheric dispersion modes
摘要
Abstract
The radionuclides atmospheric dispersion modes can be used to simulate transportation and diffusion of radionuclides in different scales under normal and accident conditions,and it can provide scientific references for selecting the nuclear power plant location,monitoring the radiation environment and managing nuclear accident.The current advance and suitability of different radionuclides atmospheric dispersion modes were summarized.The results indicate that computational fluid dynamics（CFD）turbulence modes and Gaussian modes are often used for dispersion within the scope of 2 km and 20 km respectively,while Lagrangian modes and Euler modes are used for dispersion of mid-scale（20-200 km）and large-scale（more than 200 km）.Nested modes should be employed in order to avoid the intrinsic limitations of modes.Finally,the prospect of radionuclides atmospheric dispersion modes is discussed.关键词
