Assessment of U. S. domestic capacity for producing reactor-grade thorium dioxide and controlling associated wastes and effluents

Description: Demand for reactor-grade ThO/sub 2/ is likely to increase as a result of the growing interest in the application of the thorium-uranium fuel cycle to nuclear reactors. The wastes and effluents identified with the production of ThO/sub 2/ from monazite sand are waste water, tailings, dust, smoke and gas, and radionuclides (primarily, /sup 232/Th and /sup 226/Ra). There are currently an estimated 1,500 short tons of crude thorium hydroxide byproduct that can be readily converted to reactor-grade … more

Survey of Indian issues in the state of New Mexico relating to uranium mining and milling

Description: (Estimates of Indian uranium resources range from 11 to 50% of the US total resources. About 17% of New Mexico's reserves are known to be on Indian lands. New Mexico has produced almost half of the nation's uranium supply; over half of the known reserves are located within the state. However, the state has virtually no jurisdiction over development of Indian uranium. As a result, economic and environmental impacts on the state are beyond its control. The lack of state and federal control over t… more

Assessment of the radiological impact of the inactive uranium-mill tailings at Shiprock, New Mexico

Description: Uranium-mill tailings at an inactive site near Shiprock, New Mexico, contain an estimated 950 curies (Ci) of /sup 226/Ra together with its radioactive daughters. A radiological survey was conducted at this site in February 1976. Decontamination work and tailings stabilization performed at the site since that time have greatly changed conditions there and little effort was applied to quantification of potential health effects in comparison to the earlier consideration of the site at Salt Lake Ci… more

Field and modeling study of windblown particles from a uranium mill tailings pile. Interim report

Description: A field study is reported, showing that for a carbonate-leach-process mill tailings pile in the Grants, New Mexico region much of the residual radioactive constituents in the tailings is found associated with particles 7 ..mu..m in diameter and smaller. As the tailings material dries, particle attachment and aggregation occurs with the result that radioactive constituents become associated more with larger particles. Soil samples taken at surface and subsurface on radial lines extending from th… more

Radioisotopic composition of yellowcake: an estimation of stack release rates

Description: Uranium concentrate (yellowcake) composites from four mills (Anaconda, Kerr-McGee, Highland, and Uravan) were analyzed for U-238, U-235, U-234, Th-230, Ra-226, and Pb-210. The ratio of specific activities of U-238 to U-234 in the composites suggested that secular radioactive equilibrium exists in the ore. The average activity ratios in the yellowcake were determined to be 2.7 x 10/sup -3/ (Th-230/U-238), 5 x 10/sup -4/ (Ra-226/U-238) and 2 x 10/sup -4/ (Pb-210/U-238). Based on earlier EPA measu… more

Radon and radon-daughter concentrations in air in the vicinity of the Anaconda Uranium Mill

Description: Radon concentration, working level, and meteorological variables were measured continuously from June 1977 through June 1978 at three stations in the vicinity of the Anaconda Uranium Mill with measurements integrated to hourly intervals. Both radon and daughters show strong variations associated with low wind velocities and stable atmospheric conditions, and diurnal variations associated with thermal inversions. Average radon concentration shows seasonal dependence with highest concentrations o… more

Radiological impact of uranium tailings and alternatives for their management

Description: Uncontrolled tailings piles are mobile sources of fugitive dust that may produce a practically uncleanable adjacent environment. A practical procedure for managing solid tailings is addition of surface moisture, mechanical and gravitational separation of slimes, and storage of slimes below solution tailings. Presently practical alternatives for tailings management are variations of two basic methods - surface below-ground disposal. Isolation of tailings by natural materials such as clay lenses … more

Depleted uranium valuation

Description: The following uses for depleted uranium were examined to determine its value: a substitute for lead in shielding applications, feed material in gaseous diffusion enrichment facilities, feed material for an advanced enrichment concept, Mixed Oxide (MOx) diluent and blanket material in LMFBRs, and fertile material in LMFBR systems. A range of depleted uranium values was calculated for each of these applications. The sensitivity of these values to analysis assumptions is discussed. 9 tables.
