Bentonite ˈ b ɛ n t ə n ʌ ɪ t is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite one of the first findings of bentonite was in the cretaceous benton shale near rock river wyoming the fort benton group along with others in stratigraphic succession was named after fort benton montana in the mid 19th century by fielding bradford meek and f. A thixotropic bentonite dispersion is used as an intermediate supporting material obviating the need for revetting retaining wall when the trench is excavated. Bentonite plays a key role in controlling the release of radionuclides contained in the spent fuel although its main functionality is to control water inflow and to provide mechanical stability to the vertically emplaced canisters.
