Abstract

The propagation of radioactive contamination in non-head, near-surface, water-bearing strata is modeled in order to analyze the safety of a possible subsurface radwaste repository in the region of the Leningradskaya NPP. The propagation of radioactive contamination along the top water-bearing complex formed by Quaternary and Lower Cambrian deposits is studied. A map model approximation is used. The main contamination components are assumed to be 137Cs, 90Sr, and 60Co. The propagation of contamination over 50 years is predicted. It is shown that the contamination of rocks by 137Cs, 90Sr, and 60Co propagates only in the direct proximity of the section where they leak from the repository (at a distance not exceeding 10 meters). © 2013 Springer Science+Business Media New York.
