- Abstract
- The rates of leaching of elements from B-Si glass with radionuclide simulators at 90°C after 14 days are reduced by 1–2 orders of magnitude due to the formation of a gel layer on its surface. The stability of glass in water after its contact with bentonite is lower than in distilled water. Alteration of the glass is determined by the diffusion of water into it, exchange of alkalis and protons, hydrolysis and breaking of bonds between atoms in the glass network, appearance of gel, saturation of the solution with silica and alumina, precipitation of secondary phases. Radionuclides remain in the gel layer and only B, alkalis, as well as U and Mo in higher oxidation states accumulate in the solution. A significant proportion of waste simulants in glass leaching products is found in form of colloids.
