Abstract Some calculations of the oxygen potential thresholds for the reactions of liquid sodium with urania and urania—plutonia solid solutions are presented and compared with experimental data. The… (More)
Abstract Thermodynamic models have been developed to describe the phase equilibria of oxide solutions appropriate for the understanding of the chemical interactions between nuclear reactor core… (More)
The thermodynamic conditions for the reactions of sodium with urania, plutonia and solid solutions of urania-plutonia have been determined using an electrochemical method. The thermodynamic oxygen… (More)
Abstract The kinetics of the reaction between sodium and solid solutions of urania-30% plutonia have been investigated over the temperature range 500 to 800°C, and a pseudo-activation energy for the… (More)
Abstract The Enpanne code is being developed in order to describe the behaviour of fuel pins after failure. This is important if non-essential reactor shutdowns to remove failed pins are to be… (More)
Abstract Aspects of the phase equilibria and thermodynamic quantities for the various chemical reactions which can occur between sodium and irradiated oxide fuel for fast breeder reactors are… (More)
In metallic U-Pu-Zr fuel, metallurgical reactions occur between the fuel slug and the cladding, and a phase of which the melting point is relatively low is formed in the reaction zone. If a liquid… (More)
Abstract An assessment of the chemical equilibria which can occur in the fuel-clad gap of irradiated pins for water-cooled thermal reactors and liquid-sodium-cooled fast breeder reactors is… (More)
Abstract A study of the reaction between sodium and urania-ceria solid solutions has been performed over the range of ceria concentrations in the solid solutions of 3 to 80 mol.% at temperatures up… (More)
