摘要：
Against the background of increased interest in nitride fuel for transmutation of minor actinides, this paper presents the current status of UK modelling of nitride fuel pins. A new equilibrium chemistry model for nitride fuel, suitable for inclusion in fuel pin modelling codes, is described. High-temperature experiments on (U,Zr)N in a sealed capsule indicate that actinide nitrides in a nitrogen atmosphere are stable up to their melting point. The paper also recommends a set of physical and chemical properties for advanced nitride fuels, highlighting the areas where data are presently missing. (C) 2003 Elsevier Science B.V.
