Full textThe fission reaction of oxide nuclear fuel: UO2 or MOx ((U,Pu)O2) leads to the formation of fission products. Specifically, molybdenum, palladium, rhodium ruthenium and technetium are known to form metallic phases that precipitate in the fuel matrix. Throughout the nuclear fuel cycle, these phases modify the mechanical and chemical properties of the fuel. They take part in the cladding corrosion and precipitate as non-soluble particles in the fluorite matrix hindering both dissolution process of spent fuel and vitrification process for waste disposal. In some incidental events, these fission products can also interact with uranium and/or plutonium to form intermetallic phases.The goal of the present work is to improve the thermodynamic description of Mo-Pd-Rh-Ru and Pd Rh Ru U systems using the CalPhaD formalism, which combine thermodynamic data (from experiments or first principle calculations) as input with modelling based on the minimization of the internal Gibbs energy of the whole system.The selection of input data was based on a literature survey which also identified the main weaknesses and doubts. Next, the majority of these Mo-platinoid and U-platinoid binary systems were studied using metallographic and thermal analyses carried out on annealed and as-cast samples. These new results confirmed the main invariant reactions, but also highlighted the formation of new intermetallics, some resulting from the ordering of solid solutions. Phase equilibria were also assessed for the first time in the Pd-Ru-U and Rh-Ru-U ternaries. The difficulty of perfectly characterizing these transformations prevented a new assessment of the Pd-Rh-Ru-U system. Nevertheless, these new results may be useful for future optimization of the system. The results of the Mo-platinoid systems have enabled a re-optimization of the Mo Pd, Mo Rh and Mo Ru binaries, as well as the associated ternaries. A complete new description of the Mo Pd Rh Ru system is presented in this manuscript. The efficient formalism of this model makes it compatible with numerous thermodynamic databases developed to describe the thermochemistry of irradiated nuclear fuel, as well as those of backend processes

Full textThe objective of this work is to study, from a fundamental point of view, the two aspects that are catalytic activity and selectivity in reduction of nitrates and nitrites, in the presence of (not supported) catalysts Cuads/Pt prepared and characterized by use of electrochemical techniques. During the hydrogenation, the potential of the catalyst can be established spontaneously in the presence of reactants or controlled by means of a potentiostat. These three modes of control of the catalyst potential were used in this work. Various parameters were studied : copper coverage, nature of anions and cations present in the solution, pH of the solution, concentration of nitrates or nitrites, partial pressure of hydrogen and potential of the catalyst
