The mineralogical alteration of bentonite was studied in saline water at 60 and 90 °C. To obtain the altered bentonite, a crude bentonite (Kunigel V1) was dispersed into simulated sea-water, and maintained at 60 or 90 °C over 6000 h. Magnesium was

The effect of compaction of bentonite on the sorption behavior of 137Cs was studied for the safety assessment of the high level radioactive waste. The diffusion coefficients (effective De and apparent Da ) and the distribution coefficient for sorptio

The sorption and diffusion of Cs and HTO in compacted bentonite was investigated at temperatures from 30 to 60°C. The apparent (Da) and effective (De) diffusion coefficients were determined by in-diffusion and through-diffusion experiments with a co
