Much attention has been given in recent years to the modeling of the atmospheric dispersion of pollutants released from a point source. Numerous recommendations have been made concerning the choice of appropriate dispersion parameters. A series of calculations has been performed to determine the impact of these recommendations on the calculated consequences of large reactor accidents. Results of those calculations indicate that predicted accident consequences are in general not strongly sensitive to assumed dispersion parameters. However, adjustment of the Pasquill-Gifford dispersion curves for release duration and surface roughness, or use of the Vogt rather than Pasquill-Gifford curves, can have a significant impact on calculated early fatalities.
