总结:	Title screen Nowadays, NDT is mainly focused on safety purposes, but it seems possible to apply those methods to providenational and IAEA safeguards. The containment of spent fuel in storage casks could be dramatically improved incase of development of so-called “smart” spent fuel storage and transfer casks. Such casks would have tamperindicating and monitoring/tracking features integrated directly into the cask design. The microstructure of thecontainers material as well as of the dedicated weld seam is applied to the lid and the cask body and provides aunique fingerprint of the full container, which can be reproducibly scanned by using an appropriate technique.The echo-sounder technique, which is the most commonly used method for material inspection, was chosen for thisproject. The main measuring parameter is acoustic noise, reflected from material’s artefacts. The purpose is toobtain structural fingerprinting. Reference measurement and additional measurement results were compared.Obtained results have verified the appliance of structural fingerprint and the chosen control method. The successfulauthentication demonstrates the levels of the feature points’ compliance exceeding the given threshold, which differsconsiderably from the percentage of the concurrent points during authentication from other points. Sincereproduction or doubling of the proposed unique identification characteristics is impossible at the current statescience and technology, application of this technique is considered to identify the interference into the nuclearmaterials displacement with high accuracy.
