FORMALIZATION OF THE KINETICS FOR AUTOCATALYTIC DISSOLUTIONS. FOCUS ON THE DISSOLUTION OF URANIUM DIOXIDE IN NITRIC MEDIUM

Formalization of the kinetics for autocatalytic dissolutions. Focus on the dissolution of uranium dioxide in nitric medium

Uranium dioxide dissolution in nitric acid is a complex reaction.On the one hand, the dissolution produces nitrous oxides (NOX), which makes it a triphasic reaction.On Storage Table the other hand, one of the products accelerates the kinetic rate; the reaction is hence called autocatalytic.The kinetics for these kinds of reactions need to be formal
