infrastructure currently exists in the U.S. for thorium-based fuels, and the processing of thorium-based fuels is at a lower level of technical maturity when compared to processing of uranium-based fuels, costs and RD&D [research, development and deployment] requirements for using thorium are anticipated to be higher.”. The appropriateness of developing a separate unrestricted release standard for uranium and thorium at levels higher than those in 10 CFR is being considered given that: 1) source material specific licensees are currently required to cleanup sites where source.
Seepage from the Moab, Utah, USA, former uranium-ore processing site resulted in ammonia and uranium contamination of naturally occurring saline ground water in alluvium adjacent to the Colorado River. An interim ground water remediation system, operating since , is currently being evaluated for design of a long-term : Donald R. Metzler, Joseph D. Ritchey, Kent A. Bostick, Kenneth G. Pill, Elizabeth M. Glowiak. Uranium–thorium dating, also called thorium dating, uranium-series disequilibrium dating or uranium-series dating, is a radiometric dating technique established in the s which has been used since the s to determine the age of calcium carbonate materials such as speleothem or coral. Unlike other commonly used radiometric dating techniques such as rubidium–strontium or uranium.
For mining sites on state or federal land, state or federal reclamation laws and regulations dictate how the land is reclaimed, and it is probable that the state or federal governments will retain ownership of these sites. For uranium processing facilities, reclamation activities are dictated by the site license. What is thorium? Thorium is a naturally occurring radioactive metal that is found in soil, rock, and water. It is formed by the radioactive decay of uranium. Minerals such as monazite, thorite, and thorianite are rich in thorium and may be mined for the metal. Thorium has coloring properties that have made it useful in ceramic glazes.

For students of geology, this book offers a systematic overview of uranium and thorium minerals, which are known for their intense ultraviolet fluorescence and are critically important as our source of nuclear energy/5(10).
liability for the environmental cleanup of uranium and thorium processing sites that sold their product to the federal government. Cleanup of these sites is an environmental legacy of the Cold War. What distinguishes these sites is they are privately owned, and DOE’s liability is limited to the share of their production related to federal sales.
Subject of the book is Uranium and its migration in aquatic environments. The following subjects are emphasised: Uranium mining, Phosphate mining, mine closure and remediation, Uranium in groundwater and in bedrock, biogeochemistry of Uranium, environmental behavior, and modeling.
Introduction. Uranium (U) is a threatening radionuclide because it is both a radiotoxic and a chemotoxic (Bai et al.,Bhainsa and D’Souza,Hu et al., ), and poses a health risk when incorporated, especially, in aqueous forms (Bhalara et al.,Schöner et al., ).Uranium disposed into the environment can reach the top of the food chain and be ingested by humans Author: Paulo J.C.
Favas, João Pratas, Manoj S. Paul, Majeti Narasimha Vara Prasad. This book is the collection of papers from the latest International Uranium Mining and Hydrogeology Conference (UMH VII) held in Septemberin Freiberg, Germany.
It is divided to five sessions: Uranium Mining, Uranium and Phosphates, Clean-up technologies for water and soil. Uranium and daughter nuclides and basic research and modeling.
DOE Accepts Reimbursement Claims for Uranium, Thorium Processing Remediation By Staff Reports The Department of Energy is accepting claims through Sept. 13 for reimbursement of expenses for cleanup of certain uranium and thorium processing sites.
Both target values of 20 μg/l and 10 μg/l for dissolved Uranium and CHC-compounds, respectively, could not yet be reached for all remediation wells.
In accordance to the 10μSv-concept of radiation protection the improvement of specific parameters will still be necessary in order to release the complete site from the German Atomic : Jo¨rg Wo¨rner, Sonja Margraf. operation and Development (OECD/NEA) and the IAEA jointly published a book on Uranium Extraction Technology.
A primary objective of this report was to docu ment the significant technological developments that took place during the s. The purpose of this present publication is to update and expand the original book.
The solid phase materials or sorbents applied to the removal of uranium from industrial waste streams and surface waters are reviewed. The speciation of the element in the environment is discussed.
A series of examples on uranium remediation from the recent literature using the different kinds of solid phase sorbents are reviewed in detail and evaluated. The criteria for making the best choice.

3 Uranium/Thorium production: impacts, decommissioning and rehabilitation op-tions Uranium and thorium occur in the earth's crust in average concentrations in the order of ppm and ppm (g/t rock), respectively. However, for a deposit to be in a workable condition, the cutoff grade is ppm.

for sale to the federal government. The Title X Uranium/Thorium Reimbursement Program reimburses licensees of certain uranium and thorium processing sites for the portion of their cleanup costs attributable to the production and sales of uranium and thorium to the. Uranium mining and milling sites.
Main elements to be considered relevant for potential radiological exposure from uranium and thorium mining activities are uranium and thorium and elements that occur in three natural radioactive decay series (e.g.
Ac, Ra, Rn Po, Bi, Tl, [Pb], Pa, At). T his chapter outlines the basic steps involved in mining, processing, and reclamation that might be suitable for uranium ore deposits in the Commonwealth of Virginia. For uranium ore deposits, the choice of mining methods and processing options is very deposit-specific and dependent on many variables such as the quality and quantity of the ore, the shape and depth of the ore deposit, site.
For this reason, at processing sites what was once a single, long decay series (for example the series for uranium) may be present as several smaller decay series headed by the longer-lived decay products of the original series (that is, headed by uranium, uranium, thorium, radium, and lead in the case of uranium).File Size: 88KB.
“(1) any uranium or thorium processing site, including the mill, containing byproduct material for which a license, issued either by NRC or by an Agreement State, for the production at a site of any uranium or thorium derived from ore IAEA support to uranium mining worldwide Many countries have both legacy uranium mining sites, created at a time when regulatory supervision of operations was weak or absent, and are may be.

Much is already known about the environmental impacts of mining, both on-site and off-site, and that body of information provides a basis for this chapter. However, the primary emphasis of the chapter is on the unique impacts caused by.Determination of thorium, uranium, and potassium elemental concentrations in surface soils in Cyprus Michalis Tzortzis and Haralabos Tsertos* Department of Physics, University of Cyprus, P.O.
