Book Synopsis 236U In-Situ Production in High-Grade Mineralization at Cigar Lake, Athabasca Basin, Northern Saskatchewan by : Maria Stefanescu

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada accounts for 15% of the world's uranium production (World Nuclear Association). The Athabasca Basin in northern Saskatchewan Canada contains a number of high grade, uranium ore deposits which occur at, or immediately below, an unconformity between Archean and Paleoproterozoic metasediments and intrusive rocks and overlying Proterozoic sandstones. The uranium ores are largely composed of high concentrations of uraninite and Pitchblende with naturally occurring 238U/235U ratios. U- 236 (half-life of 23.42 Myr) will be produced when 235U absorbs a neutron and the nucleus does not fission. Because it is so long lived, a small amount 236U can be maintained at equilibrium levels in the natural uranium ores. One of the main questions of this research is whether or not these equilibrium levels reflect higher grades or larger amounts of uranium minerals as a result of elevated neutron fluxes from 238U and subsequent neutron absorption on 235U. As well, are there other elements within the system that will absorb these neutrons, thereby reducing that which will impinge on 235U. In this study, we have estimated the amount of 236U that is produced by calculating the neutron flux from uranium and evaluating the effects of spatially related elements such as B, Sm and Gd using their elemental neutron cross- sections and abundances. In this project we have calculated and simulated theoretically the production of 236U and then test the theoretical calculations using measurements of uranium isotopes by accelerator mass spectrometry (AMS). Once we understand the factors controlling the 236U concentration, we hypothesize that the relationship between 236U and 238U can be used as a geochemical vector within uranium exploration, with the equilibrium level possibly distinguishing between primary mineralization and remobilization and reprecipitation of this U within spatially associated secondary U mineralization.

Economic Commission for Europe and published by United Nations Publications. This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources 2009 (UNFC-2009) is a universally applicable scheme for classifying/evaluating energy and mineral reserves and resources - it is the successor to UNFC-2004. Designed as an all-encompassing framework, it enables the incorporation and unification of existing national systems, while allowing their classification units and glossary to be retained. The principal objective of UNFC-2009 is to enhance international communication by providing a simple, user-friendly and uniform format for the reporting of energy reserves and resources, using market-based economic criteria. It has been developed to meet, to the extent possible, the needs of applications pertaining to international energy and mineral studies, government resource management functions, corporate business processes and financial reporting standards
