  • Depleted uranium technical brief

    Depleted uranium (DU) is a byproduct of the process used to enrich natural uranium for use in nuclear reactors and in nuclear weapons. Natural uranium is composed of three isotopes; 234U, 235U, and 238U (see Table 1) [1]. The enrichment process concentrates both the 235U and the 234U isotopes in the product material, resulting in a waste product or byproduct depleted in both 235U and 234U. The ...

  • Uranium city culvert headwall, Uranium City, Sask., Canada - Case Study

    In the province of Saskatchewan, Canada, Highway 962 services the remote northern community of Uranium City. Uranium City is located in the extreme northwestern cor-ner of Saskatchewan, north of Lake Athabasca, 30 mi. (48.3 km) south of the border of the Northwest Territories. The city was developed and named as a result of a significant uranium deposit that was first explored in 1946. At one ...

  • Determination of uranium concentration in surface soil samples of Iran

    The use of uranium-tipped antitank shells during the Iraq war (2003) caused serious concerns in Iran and the international media over possible contamination of the Iranian environment and consequent long-term health effects. After a shell explosion, uranium is discharged by fire into the air in the form of oxidised particles, which can be dispersed over a radius of several kilometres. Gamma ray ...

  • Biokinetic modeling of uranium in man after injection and ingestion

    Uranium is a naturally occurring primordial radioactive element. Small amounts found in air, water, and food are regularly consumed and inhaled by humans. Even the military, medical, and industrial use of depleted uranium can affect humans. There is an appreciable retention of incorporated uranium in skeleton, kidneys, and liver, and a review of respective effective dose coefficients has been ...

  • ANDalyze Case Study - Uranium in Ground Water

    Good Water Company (Testing Service) Groundwater samples were submitted by well owners from different regions of New Mexico (around Espanola region) in a water clinic sponsored by the Good Water Company. Problem/Task The groundwater in this region is contaminated with natural uranium, often above the EPA maximum contaminant level of 30 ppb uranium. ...

  • Effect of sulfate on the simultaneous bioreduction of iron and uranium

    The biogeochemistry related to iron- and sulfate-reducing conditions influences the fate of contaminants such as petroleum hydrocarbons, trace metals, and radionuclides (i.e., uranium) released into the subsurface. An understanding of these processes is imperative to successfully predict the fate of contaminants during bioremediation scenarios. A series of flow-through sediment column experiments ...

  • Uranium mining and milling: material security and risk assessment

    At present, physical protection for the front end of the nuclear fuel cycle is typically at a significantly lower level than at any other part of the nuclear fuel cycle. However, in view of past experiences it is feasible to take into consideration some generic threat scenarios, potentially resulting in loss of control over the nuclear material, respectively its by-products, such as: illegal ...

  • Recovery of uranium and vanadium from brine streams and oceans

    Research and technological developments are being pursued vigorously all over the globe to reduce the cost of desalinated water. One approach can be to retrofit 'value addition' by the recovery of uranium and vanadium from reject brine streams. Bench-scale field trials that have been carried out are presented in this paper. Coupling 'uranium recovery' with desalination plants for partly ...

  • Exploring ecotoxicological fish bioassay for the evaluation of uranium reprotoxicity

    Although reproduction in fish is known to be sensitive to metal exposure, few ecotoxicological studies have focused on the toxicological effects of metals on reproduction in fish. Because uranium (U) is naturally present in aquatic ecosystems (0.6–2 mg/L), freshwater organisms are subjected to chronic U exposure. Although new standardised assays are currently being developed to mimic realistic ...

  • Challenges in the design of a prototype contactor assembly for the recovery of uranium from seawater

    The total estimated quantity of uranium in oceans is around four and a half billion tonnes. Harvesting uranium from seawater is much less taxing to the environment. Thus, when uranium is harvested from seawater with near-zero environmental burdens, it will become a totally green fuel in the hands of humankind, as uranium generates primary calories without giving CO2 emissions and leaves no mill ...

  • Donor-dependent extent of uranium reduction for bioremediation of contaminated sediment microcosms

    Bioremediation of uranium was investigated in microcosm experiments containing contaminated sediments from Oak Ridge, Tennessee to explore the importance of electron donor selection for uranium reduction rate and extent. In these experiments, all of the electron donors, including ethanol, glucose, methanol, and methanol with added humic acids, stimulated the reduction and immobilization of ...

  • Ultrasonic density measurement of uranium loaded organic phase in solvent extraction process

    The application of ultrasound technique in density determination of uranium loaded organic phase in solvent extraction can provide a unique solution for online density monitoring of process streams.

  • Experimental determination of heat transfer coefficients in uranium zirconium hydride fuel rod

    The heat generated by nuclear fission is transferred from fuel elements to the cooling system through the fuel-to-cladding gap and the cladding-to-coolant interfaces. The fuel thermal conductivity and the heat transfer coefficient from the cladding to the coolant were evaluated experimentally. A correlation for the gap conductance between the fuel and the cladding was also presented. As the ...
