Abstract
In case of a nuclear reactor accident, radionuclides are emitted in ch emical forms which determine their mobility in the environment. Two st ages are important in this aspect: (i) the emission stage which depend s on the temperature and composition of the nuclear fuel and (ii) the so called 'maturation stage' during which UO2 aerosols react with gase s and vapours in the plume of the damaged reactor or in the atmosphere of the confinement structure. The oxidizing nature and the temperatur e of the reacting gases exert a strong influence on the solubility of fission products carried by UO2 aerosols.
