Evaluation of radionuclide geochemical information developed by DOE high-level nuclear waste repository site projects. Annual progress report, October 1982-September 1983
This report summarizes the results of the activities of the first year in a Nuclear Regulatory Commission (NRC) supported, experimentally oriented project to evaluate geochemical information (primarily radionuclide sorption and apparent concentration limit values). The geochemical information is being developed by the Department of Energy (DOE) in their high-level waste repository site projects for use in site performance assessment calculations. All work this year was focused on the candidate site in basalt being characterized by the Basalt Waste Isolation Project (BWIP). Activities involved measuring values for technetium and neptunium under geochemical parameters expected to be relevant to the site. Oxic (air saturated), reducing (hydrazine added), and anoxic (air excluded) redox conditions were employed in batch contact tests. Geochemical modeling calculations using available thermodynamic data and codes also were carried out to evaluate site groundwaters. The results are compared to values published by BWIP as conservative best estimate numbers in their Site Characterization Report and to other values and information in other available BWIP reports. 45 references, 9 figures, 13 tables.
