Geochemical Model of the Environmental Impact of Low-Level Radioactive Sludge Repositories in the Course of Their Decommissioning

摘要

The impact of a low-level radioactive sludge repository on the environment (surrounding soils, groundwater, surface waters) was substantiated by on-site observations in combination with data of experimental and thermodynamic modeling. The efficiency of natural geochemical barriers preventing the uranium release beyond the repository was evaluated. The main forms of uranium transfer and accumulation in waters and soils were revealed by experiments and on-site observations.
