摘要

If a Type B cask carrying spent nuclear fuel is in a traffic accident, some radioactive material could be released to the environment. Dispersion of this material is usually modeled as Gaussian dispersion which is inapplicable closer than about 30 meters to the source of the released material. This document describes an initial attempt to model dispersion from the source out to 20 to 30 meters from the source, in the "near field. " Preliminary results of this model suggest that less radioactivity is dispersed when there is a release from the cask than has been postulated in other studies. However, there is also a strong indication that radioactive material would be trapped near the cask by the downwash on the downwind side of the cask.
