| Abstract: | Safety Report 1997 (SR 97) of the Swedish Nuclear Fuel and Waste Management Company is a comprehensive performance assessment
of three hypothetical radioactive waste repositories in Sweden. It includes hydrogeologic studies (data compilation, parameter
synthesis, and groundwater flow modeling) to determine groundwater flow and the associated uncertainties for the three sites.
This report reviews and compares the hydrogeologic characterization programs, the site characteristics, and the groundwater
flow models used in the SR 97 performance assessment. Although differences in site-characterization programs tend to mask
differences in site characteristics, the sites do have notable differences that affect the results of the performance assessment.
The effects of model uncertainties evaluated by the variant cases appear to be smaller than the variability of results for
the base case (best estimate of site conditions) of each site.
