This paper presents the results of applying specific time series statistical techniques to observed historical groundwater-climate data at the Ranger uranium project. By developing and applying existing statistical techniques, rarely used in mining studies, improved confidence about the understanding of the groundwaterclimate relationship at the Ranger uranium project is obtained. This forms a ...

The swelling that occurs in uranium dioxide as a result of radiation-induced defect ingrowth is not fully understood. Experimental and theoretical groups have attempted to explain this phenomenon with various complex theories. In this study, experimental lattice expansion and lattice super saturation were accurately reproduced using a molecular dynamics simulation method. Based on their resembl...

X-ray diffraction has been used to probe the radiolytic corrosion of uranium dioxide. Single crystal thin films of UO(2) were exposed to an intense X-ray beam at a synchrotron source in the presence of water, in order to simultaneously provide radiation fields required to split the water into highly oxidising radiolytic products, and to probe the crystal structure and composition of the UO(2) l...

In this work we describe thickness measurements from oxide layers on uranium and tantalum using Energy Dispersive Spectroscopy (EDS) combined with Oxford Instruments software calculating the layer thickness from measured X-ray intensities. A comparison of the oxide distribution is shown between (1) a user standardised system with an older SDD detector and INCA ThinFilmID and (2) the latest larg...
