Characterization of radionuclide inventories in nuclear waste packages is performed in routine operation by the correlation of hard-to-measure nuclides to so-called key nuclides, which can be measured directly through the outside of the package. The correlations are derived from statistical evaluations of activity measurement data. The range of radiochemical methods used to determine activity concentrations of hard-to-measure radionuclides has been enlarged by the development of improved or new techniques. Standardized procedures have been developed and applied to the analytical methods for activity measurements. Furthermore, an intercomparison test has been performed between laboratories from five States on two typical nuclear power plant waste streams. A significant number of measurements have been performed on resins, evaporator concentrates and filter cartridges from nuclear power plants and on solid mixed waste from reprocessing operations.
