Abstract

Analytical parameters sufficient for identification of nuclear material of unknown origin have been assayed for a number of examples of uranium dioxide fuel. These parameters comprise isotopic composition of uranium and the morphology features of a fuel pellet. However, in practice, it occurs that a sample of an industrial material corresponds frequently to the specification limits of several suppliers. In order to further narrow a range for potential sources, additional analytical parameters are necessary, such as a fuel pellet impurity levels and surface roughness. In this study we utilize results from the following nuclear analytical techniques: thermal-ionisation mass spectrometry, glow discharge mass spectrometry and profilometry. By way of example, we demonstrate how these results serve to differentiate the sources of confiscated, vagabond nuclear materials.
