dc.description.abstractThe aim of this work was to study the effect of fission fragment damage on the dissolution of UO$_2$ thin films in water. For this purpose, thin films of UO$_2$ on LSAT (Al$_{10}$La$_3$O$_{51}$Sr$_{14}$Ta$_7$) substrates were produced and irradiated by 92 MeV $^{129}$Xe$^{23+}$ ions to a fluence of 4.8 × 10$^{15}$ ions/cm$^2$ to simulate the fission damage and induce chemical mixing that occur within nuclear fuels. The dissolution experiment was conducted under a nitrogen atmosphere (200–900 O$_2$ ppm in N$_2$ ) to study the effect of the induced irradiation damage and mixing on the dissolution of the UO$_2$ matrix. The irradiated samples showed a decrease in the amount of dissolved uranium, as compared to the corresponding unirradiated samples. This was ascribed to the irradiation-induced chemical mixing of the UO$_2$ films with the substrate elements, which resulted in stabilisation of the UO$_2$ matrix and increased its aqueous durability. Secondary phases were also observed on the surface of the UO$_2$ films after the dissolution experiment.
dc.description.sponsorshipThe irradiation experiment was performed at the Grand Accelelerateur National d’Ions Lourds (GANIL) Caen, France, and supported by the French Network EMIR. AFM, SEM and EDX experiments were performed with support of M.V.Lomonosov Moscow State University Program of Development. A.J.
