Long-term survivability of riprap for armoring uranium-mill tailings and covers: a literature review. [203 references]

Description: Pacific Northwest Laboratory (PNL) is investigating the use of a rock armoring blanket (riprap) to mitigate wind and water erosion of an earthen radon suppression cover applied to uranium mill tailings. Because the radon suppression cover and the tailings must remain intact for up to 1000 years or longer, the riprap must withstand natural weathering forces. This report is a review of information on rock weathering and riprap durability. Chemical and physical weathering processes, rock character… more

Stability of ceramic waste forms in potential repository environments: a review

Description: Most scenarios for geologic disposal of high-level nuclear waste include the eventual intrusion of groundwater into the repository. Reactions in the system and eventual release of the radionuclides, if any, will be controlled by the chemistry of the groundwater, the surrounding rock, the waste form, and any engineered barrier materials that are present, as well as by the temperature and pressure of the system. This report is a compilation and evaluation of the work completed to date on interact… more

Soil-water impacts from using vegetation and rock covers for surface stabilization of uranium-mill tailings

Description: This paper presents the results from an analysis of vegetated and rock covers and their effect on the moisture content in a covered uranium mill tailings system. Based on a one-dimensional analysis of moisture movement, the results indicate that care must be taken when selecting a surface stabilization system for a tailings pile. The moisture-content response of the tailings pile and cover system can be radically altered by different surface treatments. The two cases considered in this study in… more

Uncertainties associated with geologic disposal of high-level radioactive waste

Description: This paper focuses on uncertainties associated with models for predicting: (1) groundwater transport of radionuclides between a repository and the biosphere; and (2) long-term collective dose and health effects following release of long-lived radionuclides to the biosphere. We do not present numerical estimates of uncertainties in such predictions. Rather, we emphasize the various sources of uncertainty and attempt to evaluate the extent to which current models and supporting data bases can rea… more

Evaluation of environmental-control technologies for commercial nuclear fuel-conversion (UF/sub 6/) facilities

Description: At present in the United States, there are two commercial conversion facilities. These facilities process uranium concentrate into UF/sub 6/ for shipment to the enrichment facilities. One conversion facility uses a dry hydrofluor process, whereas the other facility uses a process known as the wet solvent extraction-fluorination process. Because of the different processes used in the two plants, waste characteristics, quantities, and treatment practices differ at each facility. Wastes and efflue… more
