- Abstract
Variation of the speciation of Np, U, and Cs in a sand-clay rock from the Kornilovskoe deposit in relation to the time of radionuclide contact with the rock was studied, and mineralogical changes in the rock composition during 500-year period of functioning of a barrier based on this material were estimated. With an increase in the time of the barrier functioning, migration of radionuclides through sand-clay rocks will decrease. Neogenic montmorillonite will also be formed, which will enhance the sorption properties of the barrier under the conditions of a surface repository of solid radioactive wastes.
