The dissolution of plutonium dioxide (PuO
) is of a fundamental importance from the point of view of energy as well as enviroment. In this work the mechanism of mediated electrochemical dissolution of semiconducting plutonium dioxide (PuO) particles in nitric acid (HNO
) was studied on the basis of experimental kinetics published so far. It was found that the rate-controlling reaction is an interfacial electron transfer process between the solid tetravalent plutonium Pu
(s) and an aqueous metal ion such as reductive U(aq) or oxidative Ce(aq) ion. The rupture of covalent bond of Pu-O of the possible [PuO
]
cluster in the (110) plane of the cubic PuO lattice by electron transfer is decisive for the dissolution process. The role of HOMO and LUMO of the [PuO] cluster is discussed with regards to the oxidative and reductive dissolution respectively.

Times Cited Count：1 Percentile：14.6(Chemistry, Physical)The previous ternary phase diagram of U-Pu-O system is invalid because the air-oxidation of (U,Pu)O is irreversible. The air-oxidation behavior of (U,Pu)O is discussed from the kinetic viewpoint.
