Short description of the work
An ongoing program of research performed at ITU includes the structural, thermomechanical and thermodynamic investigations of the reaction products between (U, Pu, Np)O2 fuels and sodium. Numerous sodium-uranates, -plutonates and -neptunates have been identified in the Na-An-O systems (An= U, Np, Pu) but none of the compounds, synthesized by solid-state synthesis, have ever been obtained as a single phase which is necessary for the measurements of their thermodynamic properties. In the present studies various routes of synthesis have been explored in order to get pure compounds. This work was part of a six months traineeship offered to a student of Chimie-Paristech. The first step of this research program has been to develop new methods of synthesis with identified surrogate elements to obtain pure compounds. This was performed by the student in the laboratories of Chimie-Paristech, Marie-Claire Illy, under the supervision of Pr. G. Wallez. The second step, which was the object of the TALISMAN proposal C0-05, was to apply those methods of synthesis to plutonium-bearing compounds. This has been done in the laboratories of ITU.
