摘要

The approaches used in long-term performance assessments to determine the impactof sorption in the geosphere on retarding the movement of radioactive contaminants have been reviewed. A comparison is made between the approaches used in the 1994 assessment of the Whiteshell Research Area in Canada and in similar assessments conducted in other countries. The long-term performance assessments reviewed were the ACEL-EIS, the TVO-92 assessment conducted in Finland, the PNC-H3 project from Japan, the SKI Project-90 and SKB-91 assessments performed in Sweden, the Kristallin-I assessment done in Switzerland, and the NIREX-95 assessment performed in the United Kingdom. In each of these assessments, the effect of sorption in the geosphere on contaminant transport was assessed using the 'Kd concept'. The sorption data were selected to reflect the anticipated effects of the reference geochemical conditions of the site being assessed. A number of approaches were taken to account for the uncertainty in the values selected for the sorption coefficients.
