|dc.description.abstract||A specialised set of facilities for Non-Destructive Examinations (NDE) is operated since more than four decades in the β-, γ-reception hot cell of the Institute for Transuranium Elements (ITU), where the ir-radiated fuel rods are delivered. The inspection techniques, including multi-isotope γ-spectrometry, de-fect detection and corrosion examination with eddy-current, dimensional measurements, visual control and gas analysis of the plenum region are performed with modern updated devices. The system has proven over long period to be a powerful tool providing key information on the state and physical con-dition of several hundred irradiated fuel rods. The fuel's burn up level for instance can be estimated through evaluation of the γ-spectra and the shadow corrosion of spent BWR rods is easily detected by means of eddy-current measurements. Fuel swelling, measurable through profilometry or fuel stack elongation is also part of the NDE deliverables. The data collected by NDE are very important for an effective planning of the subsequent rod sectioning and destructive examination. Locations where in-tense external corrosion is measured represent potential clad failure spots or regions where other anomalies may have occurred. Such locations are natural candidate positions for sampling and further detailed analysis. In this paper we present the configuration and actual status of the NDE equipment and demonstrate the system's performance with some representative results.||en_GB|
