The systematic presence of the ternary phases U6Mo4Al43and UMo2Al20is reported in a U–Mo/Al interaction layer grown by thermal annealing. This work shows, therefore, the low Mo solubility in UAl3and UAl4binary phases; it contradicts the hypothesis of the formation of (U,Mo)Al3and (U,Mo)Al4solid solutions often admitted in the literature. Using µ-XAS (micro X-ray absorption spectroscopy) at the MoKedge and µ-XRD (micro X-ray diffraction), the heterogeneity of the interaction layer obtained on a γ-U0.85Mo0.15/Al diffusion couple has been precisely investigated. The UMo2Al20phase has been identified at the closest location from the Al side. Moreover, µ-XRD mapping performed on an annealed fuel plate enabled the characterization of the four phases resulting from the γ-U0.85Mo0.15/Al and (U2Mo + α-U)/Al interactions. A strong correlation between the concentrations of UAl4and UMo2Al20and those of UAl3and U6Mo4Al43has been shown.

AbstractThe choice of surrogate for plutonium oxide for use during the initial stages of research into the immobilization of intermediate level pyrochemical wastes containing plutonium andamericium oxides in a calcium phosphate host has been investigated by powder X-ray diffraction and X-ray absorption spectroscopy. Two non-radioactive surrogates, hafnium oxide and cerium oxide, together with radioactive thorium oxide were compared. Similarities in behaviour were observed for all three surrogates when calcined at the lowest temperature, 750°C but differences became more pronounced as the calcination temperature was increased to 950°C. Although some reaction occurred between all the surrogates and the host to form a substituted whitlockite phase, increasing the temperature led to a significant increase in the cerium reaction and the formation of an additional phase, monazite. Additionally it was observed that the cerium became increasingly trivalent at higher temperatures.
