Nuclear waste viewed in a new light
Abstract
How do you characterise the contents of a sealed nuclear waste packagewithout breaking it open? This question is important when the containedcorrosion products are potentially reactive with air and radioactive.Synchrotron X-rays have been used to perform micro-scale in-situobservation and characterisation of uranium encapsulated in grout; asimulation for a typical intermediate level waste storage packet. X-raytomography and X-ray powder diffraction generated both qualitative andquantitative data from a grout-encapsulated uranium sample before, andafter, deliberately constrained H<sub>2</sub> corrosion. Tomographicreconstructions provided a means of assessing the extent, rates andcharacter of the corrosion reactions by comparing the relative densitiesbetween the materials and the volume of reaction products. Theoxidation of uranium in grout was found to follow the anoxic U + H<sub>2</sub>Ooxidation regime, and the pore network within the grout was observed toinfluence the growth of uranium hydride sites across the metal surface.Powder diffraction analysis identified the corrosion products as UO<sub>2</sub> and UH<sub>3</sub>,and permitted measurement of corrosion-induced strain. Together, X-raytomography and diffraction provide means of accurately determining thetypes and extent of uranium corrosion occurring, thereby offering afuture tool for isolating and studying the reactions occurring in realfull-scale waste package systems.
