Radioactive Waste Storage

The paper presents a concept for disposal of Class 2 and Class 3 radioactive waste in existing workings and chambers in the underground uranium mines of the Priargunsky Industrial Mining and Chemical Union PJSC with isolation of radioactive waste storage chambers using paste backfilling made with processed uranium ore materials and sealing of cracks in host rock by injection consolidation. The need is shown to enhance the strength of radioactive waste containers to increase the number of tiers in the storage blocks to make better use of the available chamber space. Data is provided on the forecast hydrogeological conditions in deep levels (up to 1000 m) of Mine No.6.

Supercritical Co2 Fluid Extraction

Uranium is an important fuel for nuclear power, so the mining and milling of uranium is the base for development of nuclear power. Our experiments study is about the supercritical CO2 fluid extraction of uranium in low grade uranium ore, and the influence of aqueous medium, oxidants, chelating agents and other factors on the uranium leaching. In aqueous media, Fe2 (SO4)3 as the oxidants, supercritical CO2 fluid extraction of uranium has the best effect, the uranium leaching rate reaches 90.44%, significantly higher than that of the conventional acid and alkaline leaching. In the process of extraction of uranium in supercritical CO2 fluid, the uranium in uranium ore is first oxidized to hexavalent uranium, and then forms high solubility of uranyl carbonate complexes. Supercritical CO2 fluid is expected to be used in in-situ leaching of uranium mining of the low grade sandstone uranium deposits.
