Wake and dispersion models for the EBR-II building complex

Abstract Wind properties measured downwind of the reactor containment structure at the EBR-II complex were found to be in agreement with predictions made with a mathematical wake model that was derived from measurements in the wakes of suspended flat plates in a wind tunnel and modified for the presence of the ground boundary. Simultaneous concentration measurements of a tracer released in the lee of the reactor containment structure were found to be in agreement with the predictions of a mathematical dispersion model that incorporated the wake model in conjunction with atmospheric turbulence properties. The analysis provides insights into the nature and properties of building wakes in the atmosphere, and their influence on dispersion of released material.
