Kinetics of the dissolution of uranium dioxide in nitric acid. I

The kinetics of the dissolution of uranium dioxide in nitric acid have been investigated over a range of acid concentration from 0·3 to 37·0 molal. A change in the reduction mechanism for nitric acid is indicated at about 16 molal concentration. A proposed mechanism for the initial rate period of di...

Zusammenfassung:The kinetics of the dissolution of uranium dioxide in nitric acid have been investigated over a range of acid concentration from 0·3 to 37·0 molal. A change in the reduction mechanism for nitric acid is indicated at about 16 molal concentration. A proposed mechanism for the initial rate period of dissolution is consistent with experimental results and with the known thermodynamics of the system.
