Relationship Between Glass Leaching Mechanism and Geochemical Transport of Radionuclides

Abstract

ABSTRACTWhen the leaching of glasses is taken into consideration in risk analysis models, it is necessary to make a distinction between accidental and normal conditions in the repository. In accidental conditions, it is assumed that the glass will be leached by ground-water which can also be renewed. The composition of this water will be related to the aquifer existing around the repository. Under normal repository conditions the leaching process has to be analyzed separately for each geological formation considered.
