Uranium and its radioactive decay products such as radium and radon gas present a significant public health and safety hazard and environmental health risk. The exposure of people and the environment to heavy metals and radionuclides in soil, air, and water in the vicinity of legacy uranium operations in the Grants District requires mitigation through the systematic assessment and cleanup of materials and sites bearing these hazardous contaminants. In August 2010 EPA released the Five-Year Plan Grants Mining District, New Mexico to assess and cleanup hazards from legacy uranium in northwestern NM. An evaluation of the activities in the first five years (2010-2014) of such a large-scale project was performed to determine if there has been measurable progress toward major goals and specific tasks in the Plan. The Six Objectives of the Plan address the following areas: 1. ground water; 2. mines; 3. mills; 4. structures; 5. Jackpile Mine, and 6. biomonitoring. The v Plan accomplishments and progress during 2010-2014 toward completion of these six Objectives indicates that Jackpile Mine and Biomonitoring (Objectives 5 and 6, respectively) were achieved. Objectives 3 and 4 (mill sites and residential structures, respectively) show accomplishments and continuing work. Objectives relating to ground water and mine cleanup (Objective 1 and 2) show some progress but these two objectives were not fully achieved. Constraints and complexities related to regulatory practices, uncertainties, financial burden, and health impacts were identified as hindrance to full completion of the Six Objectives. Recommendations to support future work include development of an implementation plan for ground water, full enforcement of state ground water protection regulations, enhanced public involvement, and better collaboration among five-year plan agencies. vi Table of Contents List of Figures

  • Cost Analysis of Seawater Uranium Recovered by a Polymeric Adsorbent System
    IAEA-CN-216 Abstact 180 Cost analysis of seawater uranium recovered by a polymeric adsorbent system E. Schneider, H. Lindner, D. Sachde, M. Flicker The University of Texas at Austin, USA E-mail address of main author: [email protected] In tandem with its adsorbent development and marine testing efforts, the United States Department of Energy, Office of Nuclear Energy, routinely updates and expands its cost analysis of technologies for extracting uranium from seawater. If informed by repeatable data from field tests, a rigorous cost analysis can convincingly establish seawater uranium as a “backstop” to conventional uranium resources. A backstop provides an essentially unlimited supply of an otherwise exhaustible resource. Its role is to remove the uncertainty around the long-term sustainability of the resource. The cost analysis ultimately aims to demonstrate a uranium production cost that is sustainable for the nuclear power industry, with no insurmountable technical or environmental roadblocks. It is also a tool for guiding further R&D, identifying inputs and performance factors where further development would offer the greatest reduction in costs and/or uncertainties. A life cycle discounted cash flow methodology is used to calculate the uranium production cost and its uncertainty from the costs of fundamental inputs including chemicals and materials, labor, equipment, energy carriers and facilities. The inputs themselves are defined by process flow models of the adsorbent fabrication and grafting, mooring at sea, recovery, and elution and purification steps in the seawater uranium recovery process. Pacific Northwest National Laboratory (PNNL) has carried out marine tests of the Oak Ridge National Laboratory amidoxime grafted polymer adsorbent in natural seawater.

  • Uranium Contamination in the 300 Area: Emergent Data and Their Impact on the Source Term Conceptual Model

The primary objectives of these efforts were to define inventories of contaminant uranium in the subsurface environment and to identify the mechanism(s) controlling the mobility (i.e., leaching and sorption) of uranium in the 300 Area. In addition to providing insight on the fate of contaminant uranium in the vadose zone, data from these studies were used to create a “box model” of the inventory of uranium in sediments and groundwater beneath the 300 Area (Peterson et al. 2008a). While a significant amount of scientific information has been gathered as a result of these activities, there are still uncertainties regarding the location and inventory of contaminant uranium in the 300 Area vadose zone and aquifer. These uncertainties present obstacles for evaluating remediation options for the persistent uranium plume in groundwater. Opportunistic sediment samples collected during a drilling campaign in 2007 became available for uranium characterization in 2008. The primary objectives of this characterization activity were to 1) determine the extent of uranium contamination in the sediments, 2) quantify the leachable (labile) concentration of uranium in the sediments, and 3) create a data set that could be used to correlate the present data to existing 300 Area data.

  • Nuclear Power – a Flawed Case: Part 1: Why We Don't Need Nuclear
    nuclear power – a flawed case part 1: why we don’t need nuclear now In the first instalment of a two-part article arguing the case against nuclear energy, Andrew Blowers suggests that nuclear power is far from necessary either to maintain sufficient energy supply or to save the planet The case for nuclear energy is based on two simple (Scotland had declared a non-nuclear energy policy) and seemingly incontrovertible claims. One is that were initially identified as ‘potentially suitable’ for the ‘We need nuclear energy to stop the lights from deployment of new nuclear stations. Eventually the going out’; the other that ‘We must have nuclear list was reduced to eight, all at locations with existing energy to save the planet’. In this, the first of two nuclear facilities – at Bradwell, Hartlepool, Heysham, articles, I shall attempt to refute these claims and Hinkley Point, Oldbury, Sellafield, Sizewell, and Wylfa.3 argue the contrary; that we can keep the lights on Although chosen for pragmatic reasons of land and tackle the problem of climate change without availability and presumed public support, the sites nuclear energy.

IRB protocol # 14-0112 iii Abstract DeBoom, Meredith J. (PhD, Geography) Developmental Fusion: Chinese Investment, Resource Nationalism, and the Distributive Politics of Uranium Mining in Namibia Thesis directed by Professor John O’Loughlin China’s rising global influence has significant implications for the politics of natural resource extraction and development in sub-Saharan Africa. Focusing on the uranium industry, I analyze how China’s influence operates at global, national, and sub-national scales in relation to natural resource politics in the southern African country of Namibia. Specifically, I draw on multi-methods fieldwork to evaluate 1) how Namibians are engaging with Chinese investments in mining and 2) what implications these engagements have for the politics of mining and development, including natural resource ownership and the distribution of mining-associated benefits and costs.

  • Uranium Demand Higher, Supply Lower Over Long-Term
    Is the Uranium sector about to come back to life? Nuclear Power is currently a much needed source of global base load power. After the Fukushima disaster in 2011 the industry has had a severe slowdown; however signs of life are emerging as the world moves to a safer nuclear solution. The uranium metal price is accordingly showing some early signs of recovery. The chart below gives a great long term perspective, also showing uranium prices are still near historic lows. Uranium price and production graph 1947 to 2018 Global nuclear demand and supply forecasts Currently in more than 12 countries, 71 nuclear reactors are under construction, 165 are planned, and 315 are proposed. China plans to spend $2.4 trillion to expand its nuclear power generation by 6,600%. Demand side growth in new nuclear reactors continue to grow with ‘first fills’ for new reactors requiring three times the uranium up front as annual burn. Japan is restarting idled capacity, and the primary producers are cutting back on production. The graph below shows the large increase in nuclear power plants that are expected to come from China. Nuclear forecast growth 2017 to 2026 World Nuclear.org quotes the International Energy Agency (IEA) 2017 report which states: “In the Sustainable Development Scenario, low-carbon sources double their share in the energy mix to 40% in 2040, all avenues to improve efficiency are pursued, coal demand goes into an immediate decline and oil consumption peaks soon thereafter. Power generation is all but decarbonised, relying by 2040 on generation from renewables (over 60%), nuclear power (15%) as well as a contribution from carbon capture and storage (6%) – a technology that plays an equally significant role in cutting emissions from the industry sector.” Nuclear is currently about 11% of electricity supply.

  • An Environmental Critique of in Situ Leach Mining
    An Environmental Critique of In Situ Leach Mining : The Case Against Uranium Solution Mining By Gavin Mudd Victoria University of Technology A Research Report for Friends of the Earth (Fitzroy) with The Australian Conservation Foundation July 1998 Uranium In Situ Leaching : The Case Against Solution Mining i Preface The mining and export of Australian uranium has been a controversial issue for many years, and will continue to remain an intense political issue for many more years to come. With a depressed world uranium market, the mining industry has been seeking to cut costs in order to make projects more economically viable. One such method of achieving this is a mining process known as In Situ Leaching (ISL) or Solution Mining. It involves pumping chemicals into the ground to dissolve the uranium mineral “in situ” and then pumping these uranium-laden solutions back to the surface for extraction and processing of the uranium into yellowcake for export. It is claimed by the industry to be “a controllable, safe, and environmentally benign method of mining which can operate under strict environmental controls and which often has cost advantages”1. This ignores the reality of many former ISL trials and mine sites across Europe and North America, and the history of ISL trial mines in Australia. The technique of In Situ Leaching is not always controllable, safe, nor environmentally benign, and the hidden costs are usually borne by the underground environment. The process of ISL can lead to permanent contamination of groundwater, which is often used by local people and industries for drinking water supplies, and can also contaminate land which was otherwise good agriculturally productive land.
