Data handling and processing at the HEISSEN ZELLEN in Jülich using the example of gamma spectrometry

Automatic translation: Many gamma spectrometric measurements are carried out in the HOT CELLS in Jülich to determine the burn-up and fission product distribution. Both whole fuel assemblies and parts of them, as well as parts of irradiation facilities and leach solutions, are examined. One or more nuclides are quantitatively determined. The measurements are carried out either in a special gamma spectrometry cell or on wall feed-through collimators of the generally used cells, in some cases also outside the cell in the associated control areas. As the samples are irretrievable and therefore very valuable, and have to be brought to the measurement location using complex transfer and transportation processes, it is necessary to carry out the measurements with a high degree of safety.
