Highly compacted sodium bentonite for isolating rock-deposited radioactive waste products

Abstract [en]

Sodium saturated bentonite clay compacted to a high density is a very efficient isolation for preventing radiotoxic nuclides from deeply buried canisters with radioactive wastes from reaching the biosphere.^The main function of the bentonite, which is applied in the form of blocks between the rock and the canisters in large boreholes, is to provide a practically impervious barrier.^The bentonite blocks take up water and swell so that they completely fill the space between rock and canisters.^The swelling potential, which is permanent, makes the bentonite self-sealing.^This means that rock joints, which may be opened, are sealed by extruding bentonite
