Download or read book Nuclear Forensic Applications of Uranium Oxide Chemistry and Morphology written by Alison Louise Tamasi and published by . This book was released on 2015 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The entire nuclear fuel cycle is a chemistry-intensive process, from accessing the raw materials from ore, to enriching and forming the fuels, to the eventual long-term disposition or reprocessing of the spent fuel. This chemistry is vital to nuclear forensics, as the chemical history of a sample imbues it with unique signatures that should provide insight into the processing and conversion a sample has undergone. Of course, now that many countries have had nuclear programs for decades, it is appropriate to question the stability of these chemical signatures. This necessitates the assessment of what new chemical and morphological signatures are introduced by the aging in bulk uranium oxide samples, and whether those signatures can be used to elucidate the conditions under which the materials were stored. This thesis is concerned with the analysis of uranium oxide samples: both high-purity UO2, [alpha]-U3O8, and [alpha]-UO3 samples, and several legacy U3O8 and UO3 samples. The samples were aged over several years in chambers designed to control temperature and relative humidity. There are two primary focuses for analysis of these aged uranium oxides -- the first is the identification of chemical signatures using powder X-ray diffraction (p-XRD) and extended X-ray absorption fine structure (EXAFS) analysis, and the second is the identification of morphological signatures contained in scanning electron microscopy (SEM) images using a standardized lexicon for consistent textural analysis.

Download or read book Nuclear Forensic Analysis of Uranium Oxide Powders Interdicted in Victoria Australia written by and published by . This book was released on 2015 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear forensic analysis was conducted on two uranium samples confiscated during a police investigation in Victoria, Australia. The first sample, designated NSR-F-270409-1, was a depleted uranium powder of moderate purity (~1000 [mu]g/g total elemental impurities). The chemical form of the uranium was a compound similar to K2(UO2)3O4·4H2O. While aliquoting NSR-F-270409-1 for analysis, the body and head of a Tineid moth was discovered in the sample. The second sample, designated NSR-F-270409-2, was also a depleted uranium powder. It was of reasonably high purity (~380 [mu]g/g total elemental impurities). The chemical form of the uranium was primarily UO3·2H2O, with minor phases of U3O8 and UO2. While aliquoting NSR-F-270409-2 for analysis, a metal staple of unknown origin was discovered in the sample. The presence of 236U and 232U in both samples indicates that the uranium feed stocks for these samples experienced a neutron flux at some point in their history. The reactor burn-up calculated from the isotopic composition of the uranium is consistent with that of spent fuel from natural uranium (NU) fueled Pu production. These nuclear forensic conclusions allow us to categorically exclude Australia as the origin of the material and greatly reduce the number of candidate sources.

This book was released on 2017-04-25 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 52 of Reviews in Mineralogy and Geochemistry updates our knowledge of U-series geochemistry, offer an opportunity for non-specialists to understand its basic principles, and give us a view of the future of this active field of research. In this volume, for the first time, all the methods for determining the uranium and thorium decay chain nuclides in Earth materials are discussed. It was prepared in advance of a two-day short course (April 3-4, 2003) on U-series geochemistry, jointly sponsored by GS and MSA and presented in Paris, France prior to the joint EGS/AGU/EUG meeting in Nice.

Available in PDF, EPUB and Kindle. Book excerpt: Providing a theoretical background for inorganic mass spectrometry, this text describes classical applications of four modern mass spectrometers - magnetic sector, quadrupole, time-of-flight, and ion trap - and illustrates how they have impacted elemental and isotopic analysis. The book features examples that concentrate on routine and non-routine applications of inorganic analysis techniques.

Available in PDF, EPUB and Kindle. Book excerpt: John E. Mylroie and Ira D. Sasowsky' Caves occupy incongruous positions in both our culture and our science. The oldest records of modem human culture are the vivid cave paintings from southern France and northern Spain, which are in some cases more than 30,000 years old (Chauvet, et ai, 1996). Yet, to call someone a "caveman" is to declare them primitive and ignorant. Caves, being cryptic and mysterious, occupied important roles in many cultures. For example, Greece, a country with abundant karst, had the oracle at Delphi and Hades the god of death working from caves. People are both drawn to and mortified by caves. Written records ofcave exploration exist from as early as 852 BC (Shaw, 1992). In the decade of the 1920's, which was rich in news events, the second biggest story (as measured by column inches of newsprint) was the entrapment of Floyd Collins in Sand Cave, Kentucky, USA. This was surpassed only by Lindbergh's flight across the Atlantic (Murray and Brucker, 1979).

This book was released on 2012-03-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: All the solid fuels fossil energy and mineral commodities we use come out of the Earth. Modern society is increasingly dependent on mineral and fossil energy sources. They differ in availability, cost of production, and geographical distribution. Even if solid fuels, fossil energy resources and mineral commodities are non-renewable, the extracted metals can to a large extent be recycled and used again and again. Although the stock of these secondary resources and their use increases, the world still needs and will continue to need primary mineral resources for the foreseeable future. Growing demands have begun to restrict availability of these resources. The Earth is not running out of critical mineral resources – at least for the near future – but the ability to explore and extract these resources is being restricted in many regions by competing land use, as well as political and environmental issues. Extraction of natural resources requires a clear focus on sustainable development, involving economic, environmental and socio-cultural aspects. Although we do not know what the most important resources will be in 100 years from now, we can be quite certain that society will still need energy and a wide range of raw materials. These resources will include oil and gas, coal, uranium, thorium, geothermal, metallic minerals, industrial and specialty minerals, including cement, raw materials, rare-earth elements. A global approach for assessing the magnitude and future availability of these resources is called for – an approach that, with appropriate international collaboration, was started within the triennium of the International Year of Planet Earth. Some global mineral resource assessments, involving inter-governmental collaboration, have already been initiated. The International Year of Planet Earth helped to focus attention on how the geosciences can generate prosperity locally and globally, as well as sustainability issues in both developed and developing countries.
