Abstract

Feasibility study of Dutch concept of deep geological repository for radioactive waste is at present widely conducted in the Netherlands. In this project, transport properties of selenate ion in clay materials were investigated. Apparent diffusion coefficients of selenate ion were obtained as results. To study possible alternations of Boom Clay by alkaline concrete pore water, elemental composition and pore structure of raw Boom Clay samples were characterized.
