The Role of Colloids in Uranium Transport: A Comparison of Nuclear Waste Repositories and Abandoned Uranium Mines
The Role of Colloids in Uranium Transport: A Comparison of Nuclear Waste Repositories and Abandoned Uranium Mines
Zänker, H.; Ulrich, K.-U.; Opel, K.; Brendler, V.
The formation of colloids containing U(IV) or U(VI) was studied by experiments simulating colloid formation under unoxic and oxic conditions. It is concluded that both transport-facilitating effects of colloids on immobile radiotoxic contaminants such as U(IV) and transport-impeding effects on mobile radiotoxic contaminants such as U(VI) can play a part in the surroundings of nuclear waste repositories and abandoned uranium mines. The differences between the two geochemical settings are discussed.
Keywords: Colloids; uranium; solubility; nuclear waste repositories; abandoned uranium mines
