Accidents in the auxiliary building

In both accident scenarios I is the most important radionuclide because of its radiotoxicity and its potential volatility in comparison, the release of other radionuclides from the resulting sump due to droplet or aerosol carry-over can be ignored. The postulated identical release fractions of iodine and non-volatile radionuclides can only be explained by the assumed presence of iodine in the solution as iodide ion. However, such a high droplet entrainment seems to be very unlikely, since even from boiling water surfaces a significantly smaller fraction of droplets (on the order of 0.1% and less) is formed and transported over distances
