Thermodynamic Assessment of the NaCl-CrCl₂, NaCl-CrCl₃, and FeCl₂-CrCl₂ Pseudo-Binary Systems for Describing the Corrosion Chemistry Between Molten Salt Fuel and Steel

A thorough understanding of the corrosion chemistry between molten salt fuel and structural materials (e.g., steel) is key for the advancement of Molten Salt Reactor technology. In this work, we consider more specifically the case of a chloride fuel salt mixture and the thermochemistry of a salt mixture such as (NaCl-MgCl₂-PuCl<sub...

New insights into the Cs-Mo-O system: Experimental studies of the Cs₂MoO₄-MoO₃ pseudo-binary system

The ternary cesium molybdates Cs₂Mo₂O₇, Cs₂Mo₃O₁₀, Cs₂Mo₅O₁₆ and Cs₂Mo₇O₂₂ have been synthesized in this work using a solid state route and their structures have been characterized using X-ray diffraction. The...

Investigation of the Cs₂(Mo,Te)O₄Solid Solution and Implications on the Joint Oxyde-Gaine System in Fast Neutron Reactors

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...
