“…We then estimate the total rate of volume change V˙ore(F) associated with the removed ore. The total mass of produced ore in its final product form is mu3o8(F)=1.8×106 kg with a density ρu3o8=8380 kg/m3 20 . From this and the molar masses of both the final product ore Mu3o8=842 g/mole and mined ore Mu=238 g/mole, we calculate the corresponding mass of mined ore: mu(F)=mu3o8(F)/(Mu3o8×10−3)×3×(Mu*10…”

.The effect of uranium mining on ground deformation is a relatively unexplored area, especially in terms of surface subsidence related to subsurface ore removal. We use interferometric synthetic aperture radar and spatiotemporal techniques to characterize subsidence signals at the McArthur River underground mine in Canada and the Four Mile in situ leach mine in Australia. We enhance the signal-to-noise ratio of our datasets via time-series techniques and compare results from active periods with results during inactivity to establish a baseline for mining-related signals. We then relate observed surface subsidence to subsurface volumetric strain rates via a voxel parameterization and Bayesian, geostatistical inversion. We use priors on our volumetric strain rates to identify whether these rates are best attributed to ore removal or if additional factors are contributing to subsidence at these sites. We find that the subsidence at McArthur River is best explained by a combination of ore removal and thermal contraction resulting from ground freezing practices. Ore removal via solution extraction alone explains the subsidence at Four Mile, although the localized subsidence pattern and resulting strain rates suggest an intricate combination of sinks and sources in the field, possibly from injection and production well locations and the subsequent flow of solution.

“…These applications span from isotope production, environmental restoration, nuclear fuel rod fabrication, space exploration, and harvesting actinides from weapons program waste streams. 1–19 The latter topic was the major motivating factor for this particular research effort. For instance, at Los Alamos National Laboratory (LANL), transuranic actinides – like plutonium (Pu) and americium (Am) – are recovered from aqueous waste streams.…”

“…In a later development, Herbert H. Anderson and Larned B. Asprey, who were participants of the Manhattan Project; an R&D programme comprising 150 000 workers to develop the first nuclear weapons during World War II, 7,8 co-patented the plutonium–uranium reduction extraction (PUREX) process. 9 The PUREX process is a mature liquid–liquid extraction technique that works by using an extractant, tri- n -butylphosphate (TBP) diluted in paraffin (kerosene) and a salting agent, nitric acid, from which separated uranium and plutonium can be recovered and purified.…”
