A CFD approach to the atmospheric dispersion of radionuclides in the vicinity of NPPs
PAB de Sampaio, MAG Junior, CMF Lapa - Nuclear Engineering and …, 2008 - Elsevier
Most studies of atmospheric dispersion of radionuclides released from Nuclear Power Plants
(NPPs) are based on Gaussian plume models or on the use of a convection–diffusion
equation. Such methods, which do not involve solving the flow problem, are useful in the
atmospheric mesoscale, of the order of 2–2000km from the NPP. However, they do not
account for the turbulence generated by the interaction of the wind with obstacles and with
the released material stream, which are the dominant factors in the local scale, of the order …
