Investigation of the Cs₂(Mo,Te)O₄ Solid Solution and Implications on the Joint Oxyde-Gaine System in Fast Neutron Reactors.

ABSTRACT: The formation of a thin layer, the so-called Joint Oxyde-Gaine (JOG), between the (U,Pu)O₂ fuel pellets and the cladding has been observed in fast neutron reactors, due to the accumulation of volatile fission products. Cs₂MoO₄ is known to be one of the major components of the JOG, but other elements are also present, in particular tellurium and palladium. In this work, an investigation of the structural and thermodynamic properties of Cs₂TeO₄ and Cs₂Mo_1-xTe_xO₄ solid solution is reported. The existence of a complete solubility between Cs₂MoO₄ and Cs₂TeO₄ is demonstrated, combining X-ray diffraction (XRD), neutron diffraction (ND), and X
