MIGRATION OF DENSE LIQUID RADIOACTIVE WASTES IN SLOPING FRESHWATER AQUIFER
Liquid radioactive wastes (LRW) injected into deep formations usually have a density that exceeds the density of the natural groundwater present in the formations. There are two factors conditioned by the LRW properties that exert an influence on the process of distribution of injected wastes. First, the density of injected wastes often is different from the underground water density. As a result a density dependent convection in the aquifer arises. Second, the radioactive component of the wastes is sorbed onto the rocks. The density of wastes does not affect this process of sorption. Results of the three-dimensional, variable density groundwater flow modeling show that both these factors effect post-injection migration of the injected wastes in essentially different ways. The results of this research were illustrated by using data from the disposal site Severny next to Krasnoyarsk city, South Siberia, Russian Federation.
