Actinide physicochemical data assessment and selection

There is a continuing need to have reliable physicochemical data for actinide compounds and for the preparation of actinide elements in aqueous solution available for nuclear engineers and scientists. These data are needed for all aspects of the nuclear fuel cycle - from the behaviour of actinides in reactor fuels at high temperature and pressure to actinide behavior in geologic repository environments. This paper summarizes the status of actinide physiochemical data assessment and selection. The topics covered include data assessment of chemical thermodynamic properties and solubilities of actinide compounds and solution equilibria of the actinides. (orig.)
