WIND-FIELD MODELING OF NUCLEAR ACCIDENT CONSEQUENCES FOR HONG-KONG

An efficient weighted interpolation technique is used to generate a ti me series of wind fields from the measurements of seven strategically located weather stations in Greater Hong Kong. This wind-field model, HKWIND, is integrated with the atmospheric dispersion/consequence mode l RADIS to form a complete off-site nuclear accident analysis package. A study is also performed that compares the calculational results of accident consequences with and without wind-field models. The inclusio n of the wind-field model has a drastic effect on the Puff trajectory and subsequently increases the frequencies of early fatality, early in juries, and latent cancers for Hong Kong.
