Boldyrev, S.A. Bogatov ANNOTATION: The article investigates the mechanisms responsible for aluminum phosphate glass matrix (APM) leaching and quantifies the corresponding release of radionuclides beyond the system of engineered barriers of the deep geological repository (DGR) for radioactive waste. The paper considers a bentonite clay-based material as a buffer material. The leaching model of the APM was developed on the basis of an experimental study with account taken of the kinetics of leaching, surface blocking made by secondary solid mineral phases of the interaction of leached glass matrix with water and contacting bentonite. Keywords: migration of radionuclides, modeling, radioactive waste, leaching, bentonite, DGR, PhreeqC. DOWNLOAD (RU) » Boldyrev K. A., Bogatov S. A.
