  • A review of uranium economics

    The recent increase in the demand for power for commercial use, the challenges facing fossil fuel use and the prospective of cheap nuclear power motivate different countries to plan for the use of nuclear power. This paper reviews many aspects of uranium economics, which includes the advantages and disadvantages of nuclear power, comparisons with other sources of power, nuclear power production ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Why does India require uranium through the 123 Agreement?

    The government of India has taken a deliberate stand that nuclear power should be one of the components of the energy mix that the country should have for sustained economic growth. A base for this was laid in the 1960s to 1970s in collaboration with USA and Canada. However, a major part of the development, in recent decades, has been indigenous. This came about after international sanctions were ...

  • Uranium removal by chitosan impregnated with magnetite nanoparticles: adsorption and desorption

    A magnetic biosorbent composed of nanoparticles of magnetite covered with chitosan, denominated magnetic chitosan, was prepared. The magnetic chitosan showed a magnetic response of intense attraction in the presence of a magnetic field without becoming magnet, a typical behaviour of superparamagnetic material. Its adsorption performance was evaluated by the adsorption isotherm models of Langmuir ...

  • Dissolved radionuclide in the industrial effluent of uranium facilities, Jaduguda, India

    Dissolved radionuclides in the effluent of uranium mining industry were studied. Activity concentrations of uranium and radium were estimated in effluent water from different uranium mines and mill tailings ponds. The concentrations of U and 226Ra in untreated effluent water were found to be elevated. The concentrations of dissolved radionuclides in the adjacent aquatic ...

  • Campbell Ranch, Nevada Arsenic & Uranium Treatment - Case Study

    Campbell Ranch, Nevada Arsenic & Uranium Treatment In March 2009, AdEdge Water Technologies was contacted by Indian Health Services to design, manufacture, and start up an arsenic and uranium treatment system for the Campbell Ranch community in Nevada. Arsenic concentrations were approximately 0.023 mg/L and uranium concentrations were 0.047 mg/L, well above the United States ...

  • Researchers discover high uranium levels in south India groundwater

    The uranium isotopes during their course of their disintegration decay into other radioactive elements and eventually decay into stable lead isotopes. The cause of environmental concern is the emanation of beta and gamma radiation during disintegration. The present study tends to estimate uranium in groundwater trapped in granite and gneiss rocks. Besides, the study aims at estimating the ...

  • Removal of Radioactive Effluent Waste from Uranium Enrichments Plants

    In an effort to reduce greenhouse emissions many nations and multi-national corporations are once again focusing on the development of safe radioactive sources for energy generation. After a hiatus of some 20 years commercial nuclear power plants are being developed globally to satisfy increasing global energy demands. Whether for generation of electrical power or in the production of fission ...
