Automatic Analysis for Input of Nuclear Fuel Reprocessing

An automatic laboratory is described, which can analyse the reprocessing input of U and Pu by isotope dilution mass-spectrometry. A robot prepares the sample for the separations of U and Pu from fission products by an automat. Alpha- and mass-spectrometers analyse the samples and record the data automatically. The evaluation is done on-line by a central computer. Performance of the installation is described.
