To study the physical properties of a bentonite buffer, long-term test (LOT) of buffer material were performed in granitic rock 450 m underground at the Aspo Hard Rock Laboratory (HRL), Oskarshamn, Sweden. The LOT was set up under conditions similar

Publikováno v: MRS Proceedings. 608

Bentonite clay has been proposed as buffer material in several concepts for nuclear high level waste repositories. The “Long Term Test of Buffer Material” (LOT) series aims at validating models and hypotheses concerning physical properties in a b
