URANINITE ALTERATION IN AN OXIDIZING ENVIRONMENT AND ITS RELEVANCE TO THE DISPOSAL OF SPENT NUCLEAR FUEL Robert Finch Rodney Ewing Department of Geology University of New Mexico Submitted to Svensk Kämbränslehantering AB (SKB) December 21,1990 ABSTRACT Uraninite is a natural analogue for spent nuclear fuel because of similarities in structure (both are fluorite structure types) and chemistry (both are nominally UOJ. Effective assessment of the long-term behavior of spent fuel in a geologic repository requires a knowledge of the corrosion products produced in that environment. -

Near-Infrared Spectroscopy of Uranyl Arsenates of the Autunite and Metaautunite Group
Near-Infrared spectroscopy of uranyl arsenates of the autunite and metaautunite group Ray L. Frost•, Onuma Carmody, Kristy L. Erickson and Matt L. Weier Inorganic Materials Research Program, School of Physical and Chemical Sciences, Queensland University of Technology, GPO Box 2434, Brisbane Queensland 4001, Australia. Frost, Ray and Carmody, Onuma and Erickson, Kristy and Weier, Matt (2005) Near- Infrared spectroscopy of uranyl arsenates of the autunite and metaautunite group. Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy 61(8):1923. Copyright 2005 Elsevier Note: This is the authors’ version of the work. Abstract A suite of uranyl arsenates have been analysed by Near-infrared spectroscopy. The NIR spectra of zeunerite and metazeunerite in the first HOH fundamental overtone are different and the spectra of uranyl arsenates of different origins in the 6000 to 7500 cm-1 region are different. NIR spectroscopy provides a method of determination of the hydration of uranyl arsenates and has implications for the structure of water in the interlayer. Such a conclusion is also supported by the water OH stretching region where considerable differences are observed. NIR is an excellent technique for the study of the autunite minerals and may be used to distinguish between different autunite phases such as the partially dehydrated autunites for example zeunerite and metazeunerite. Keywords: abernathyite, autunite, heinrichite, novacekite, zeunerite, metazeunerite, near-IR spectroscopy Introduction The study of uranium minerals is important for the remediation of soils, the solution of environmental problems caused by radioactive materials and the uptake of radionuclides from aqueous systems. Among the many uranium minerals are a group of minerals which are very common worldwide known as the autunite group of minerals. -

Orcid Francisco Colmenero: https://orcid.org/0000-0003-3418-0735 Orcid Joaquín Cobos: https://orcid.org/0000-0003-0285-7617 Orcid Vicente Timón: https://orcid.org/0000-0002-7460-7572 *E-mail: [email protected] 1 ABSTRACT The structure and Raman spectrum of schoepite mineral, [(UO2)8O2(OH)12] · 12 H2O, was studied by means of theoretical calculations. The computations were carried out by using Density Functional Theory with plane waves and pseudopotentials. A norm-conserving pseudopotential specific for the uranium atom developed in a previous work was employed. Since it was not possible to locate hydrogen atoms directly from X-ray diffraction data by structure refinement in the previous experimental studies, all the positions of the hydrogen atoms in the full unit cell were determined theoretically. The structural results, including the lattice parameters, bond lengths, bond angles and X-ray powder pattern were found in good agreement with their experimental counterparts. However, the calculations performed using the unit cell designed by Ostanin and Zeller in 2007, involving half of the atoms of the full unit cell, leads to significant errors in the computed X-ray powder pattern. Furthermore, Ostanin and Zeller’s unit cell contains hydronium ions, + H3O , that are incompatible with the experimental information. Therefore, while the use of this schoepite model may be a very useful approximation requiring a much smaller amount of computational effort, the full unit cell should be used to study this mineral accurately. -

Clarkeite: New Chemical and Structural Data
American Mineralogist, Volume 82, pages 607±619, 1997 Clarkeite: New chemical and structural data ROBERT J. FINCH* AND RODNEY C. EWING Department of Earth and Planetary Sciences, University of New Mexico, Albuquerque, New Mexico 87131, U.S.A. ABSTRACT Clarkeite crystallizes during metasomatic replacement of pegmatitic uraninite by late- stage, oxidizing hydrothermal ¯uids. Samples are zoned compositionally: Clarkeite, which is Na rich, surrounds a K-rich core (commonly with remnant uraninite) and is surrounded by more Ca-rich material; volumetrically, clarkeite is most abundant. Clarkeite is hexag- onal (space group Rm3Å )a53.954(4), c 5 17.73(1) AÊ (Z 5 3). The structure of clarkeite is based on anionic sheets of the form [(UO2)(O,OH)2]. The sheets are bonded to each other through interlayer cations and H2O molecules. The empirical formula for clarkeite from the Fanny Gouge mine near Spruce Pine, North Carolina, is: {Na0.733K0.029Ca0.021Sr0.009Y0.024Th0.006Pb0.058}S0.880[(UO2)0.942O0.918(OH)1.082](H2O)0.069. Na predominates and the Pb is radiogenic. The general formula for clarkeite is 21 31 41 {(Na,K)pMMMPbqr s x}[(UO2)1 2 xO1 2 y(OH)1 1 y](H2O)z where Na .. K and p . (q 1 r 1 s). The number of O22 ions and OH groups in the structural unit is determined by the net charge of the interlayer cations (except Pb): y 5 1 2 (p 1 2q 1 3r 1 4s). This suggests that the ideal formula for ideal end-member clarkeite is Na[(UO2)O(OH)](H2O)0-1. -

National Museum, Václavské náměstí 68, 115 79 Praha 1, Czech Republic. Abstract Raman and infrared spectra of the uranyl oxyhydroxide hydrate: curite is reported. 2+ Observed bands are attributed to the (UO2) stretching and bending vibrations, U-OH - bending vibrations, H2O and (OH) stretching, bending and librational modes. U-O bond lengths in uranyls and O-H…O bond lengths are calculated from the wavenumbers assigned to the stretching vibrations. These bond lengths are close to the values inferred and/or predicted from the X-ray single crystal structure. The complex hydrogen-bonding network arrangement was proved in the structures of the curite minerals. This hydrogen bonding contributes to the stability of these uranyl minerals. Key words: curite, uranyl mineral, Raman and infrared spectroscopy, U-O bond lengths in uranyl, hydrogen-bonding network Introduction The lead uranyl oxide hydrate minerals, PbUOHs, are a group of natural uranyl oxide hydrates that are formed and therefore are also present in oxidized zones of geologically old uranium deposits, owing to the buildup of radiogenic divalent Pb2+ [1-3]. -
