Ultrasonic Fingerprinting of Structural Materials: Spent Nuclear Fuel Containers Case-Study / D. A. Sednev, A. M. Lider, D. G. Demyanuk {et al.]
Уровень набора: Physics Procedia, Scientific Journal = 2008-Язык: английский.Страна: .Резюме или реферат: 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.
