Distribution of wind pressures on the outer surface of the New Safe Confinement (NSC) is necessary to determine the unorganized air exchange from the NSC (outward or inward) with radioactive aerosols to the environment, since it is not hermetically sealed. The results show the discrepancy between the wind pressure distribution on the NSC outer surface in the small-scale 1:300 physical model of the NSC tested in the wind tunnel and the literature data. The computational CFD model of the NSC external air flow was developed to determine the distribution of pressures on the NSC surface at different wind directions and speeds. The adequacy of the calculated model is confirmed by the proximity of calculated and literature data, as well as calculations according to the European standard.
