Abstract

Changes in the visual characteristics of uranium oxide surfaces and morphology following storage under different conditions of temperature and relative humidity may provide insight into the history of an unknown sample. Sub-samples of three α-U₃O₈ materials—one that was phase-pure and two that were phase-impure—were stored under controlled conditions for two years. We used scanning electron microscopy to image the oxides before and after storage, and a morphology lexicon was used to characterize the images. Finally, temporal changes in morphology were observed in some sub-samples, and changes were greatest following exposure to high relative humidity.

Hydration of α-UO₃ following storage under controlled conditions of temperature and relative humidity

Journal Article Wilkerson, Marianne P. ; Hernandez, Sarah C. ; Mullen, W. Tyler ; ... - Dalton Transactions

Changes in chemical speciation of uranium oxides following storage under varied conditions of temperature and relative humidity are valuable for characterizing material provenance. In this study, subsamples of high purity α-UO₃ were stored under four sets of controlled conditions of temperature and relative humidity over several years, and then measured periodically for chemical speciation. Powder X-ray diffraction (XRD) analysis and extended X-ray absorption fine structure spectroscopy confirm hydration of α-UO₃ to a schoepite-like end product following storage under each of the varied storage conditions, but the species formed during exposure to the lower relative humidity and lower temperature condition followsmore »« less

Oxidation and Hydration of U₃O₈ Materials Following Controlled Exposure to Temperature and Humidity

Journal Article Tamasi, Alison L. ; Boland, Kevin S. ; Czerwinski, Kenneth ; ... - Analytical Chemistry

Chemical signatures correlated with uranium oxide processing are of interest to forensic science for inferring sample provenance. Identification of temporal changes in chemical structures of process uranium materials as a function of controlled temperatures and relative humidities may provide additional information regarding sample history. In this study, a high-purity α-U3O8 sample and three other uranium oxide samples synthesized from reaction routes used in nuclear conversion processes were stored under controlled conditions over 2–3.5 years, and powder X-ray diffraction analysis and X-ray absorption spectroscopy were employed to characterize chemical speciation. Signatures measured from the α-U3O8 sample indicated that the material oxidizedmore »« less

Effect of Diel Cycling Temperature, Relative Humidity, and Synthetic Route on the Surface Morphology and Hydrolysis of α-U₃O₈

Journal Article Hanson, Alexa Brooke ; Nizinski, Cody A. ; McDonald IV, Luther W. - ACS Omega

The speciation and morphological changes of α-U₃O₈ following aging under diel cycling temperature and relative humidity (RH) have been examined. This work advances the knowledge of U-oxide hydration as a result of synthetic route and environmental conditions, ultimately giving novel insight into nuclear material provenance. α-U₃O₈ was synthesized via the washed uranyl peroxide (UO₄) and ammonium uranyl carbonate (AUC) synthetic routes to produce unaged starting materials with different morphologies. α-U₃O₈ from UO₄ is comprised of subrounded particles, while α-U₃O₈ from AUC contains blocky, porous particles approximately an order of magnitude larger than particles from UO₄. For aging, a humidity chambermore »« less

RadMAP: The Radiological Multi-sensor Analysis Platform

Journal Article Bandstra, Mark S. ; Aucott, Timothy J. ; Brubaker, Erik ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

The variability of gamma-ray and neutron background during the operation of a mobile detector system greatly limits the ability of the system to detect weak radiological and nuclear threats. The natural radiation background measured by a mobile detector system is the result of many factors, including the radioactivity of nearby materials, the geometric configuration of those materials and the system, the presence of absorbing materials, and atmospheric conditions. Background variations tend to be highly non-Poissonian, making it difficult to set robust detection thresholds using knowledge of the mean background rate alone. The Radiological Multi-sensor Analysis Platform (RadMAP) system is designedmore »« less

Morphologic and chemical characterization of products from hydrolysis of UF₆

Journal Article Wagner, Gregory L. ; Kinkead, Scott A. ; Paffett, Mark T. ; ... - Journal of Fluorine Chemistry

Characterization of the chemical speciation and morphologies of products formed from hydrolysis of uranium hexafluoride (UF₆) is important for predicting dispersion and contamination of released material, or health consequences from inhalation of air-borne particles. Here, we report products of hydrolysis of UF₆ in which the quantity of water was insufficient for complete formation of UO₂F₂. Material was deposited onto carbon tape and aluminum. Scanning electron microscopy was employed to characterize textures and particle sizes, and powder X-ray diffraction analysis and μ-Fourier transform infrared absorption spectroscopy were used to characterize chemical speciation. These results revealed that the ratio of H₂O tomore »« less
