- Abstract
- In the case of a severe nuclear reactor accident, UO2 particles may be emitted as a consequence of mechanical disintegration of the fuel. Once in the atmosphere, various physico-chemical reactions may then occur between the partially vitrified dioxide and vapours from the reactor; these reactions are able to incorporate fission products into the UO2 particles and reduce their availability to the environment. Caesium,for example, which is usually very soluble, can react with fuel UO2 and iron from the reactor structures and be included in chemical forms such as uranates or ferrites where its solubility is greatly reduced.
