In this chapter the functions and requirements of bentonite in a repository for spent nuclear fuel are discussed. These requirements concern, for example, swelling pressure, hydraulic conductivity, and diffusion properties. Mineralogy and analysis te

Bentonites are candidate materials for encapsulation of radioactive waste. The cation exchange capacity (CEC) has proven to be one of the most sensitive parameters for detecting changes in mineral properties in bentonite-alteration experiments. An in

We present molecular dynamics simulations of the Donnan equilibrium principle in compacted montmorillonite with three hydration layers of water in the interlayer. This draws attention to the misconception, frequently seen in the literature, stating t

As a model for ion equilibrium in montmorillonite, the Poisson–Boltzmann (PB) equation was solved for two parallel charged surfaces in contact with an external NaCl/CaCl 2 mixed solution. The ion concentration profiles in the montmorillonite interl

Various colloidal phases of Wyoming type Ca/Na-montmorillonite have been investigated experimentally by sedimentation and swelling tests of originally pure Ca- or Na-montmorillonite in different CaCl2/NaCl solutions of low ionic strength. Forces cont

Compound Ca/Na-montmorillonites were prepared by mixing given amounts of homoionic Ca-montmorillonite with given amounts of homoionic Na-montmorillonite. Colloidal sol formation in deionized water of these mixed Ca/Na-montmorillonites were investigat

Bentonite clay is proposed as buffer material around the waste canisters and as tunnel backfill material in several concepts for disposal of radioactive waste. The distribution of charge compensating cations in the bentonite is of interest for severa

Bentonite clay is proposed as buffer material in several concepts of High Level Radioactive Waste repositories, and a correct description of ion diffusion in this material is of vital importance for any quantification of the chemical evolution of the
