    Minerals and natural analogues
    (Elsevier, 2012-02-01) Lumpkin, GR; Geisler-Wierwille, T
    Ceramic waste forms have been considered as options for the disposal of nuclear waste in geological repositories. Major issues for waste forms are their behavior in response to α-decay damage and the presence of aqueous fluids for time scales on the order of 10 000 years. Studies of minerals from geological systems may reveal information about radiation damage response together with dissolution–precipitation or chemical exchange reactions with hydrothermal and low temperature fluids. Studies of radioactive minerals also include laboratory tests of chemical durability and the kinetics of structural recovery. Chemical durability studies can be further extended to include dissolution tests on irradiated and unirradiated synthetic material. In certain cases, the host rocks themselves, for example, uranium ore deposits, have been studied as analogs for spent nuclear fuel in geological repositories. Copyright © 2012, Elsevier
