DOI: 10.1007/s10706-016-0105-8
Abstract: Densely compacted bentonite has been identified as a potential buffer in deep geological repositories as the expansive clay satisfies the hydro-mechanical and physico-chemical functions of the buffer material. A key feature in understanding the hydro-mechanical… read more here.

DOI: 10.1016/j.clay.2017.03.006
Abstract: This study compares the capabilities of two numerical models that simulate the behaviour of compacted saturated MX-80 bentonite exposed to different chemical environments. Both codes have different approaches: one of them is a reactive transport… read more here.

DOI: 10.1016/j.enggeo.2019.105204
Abstract: Abstract In high-level radioactive waste repositories, compacted bentonite used as buffer/backfill materials should have enough strength and stiffness to enhance the stability of the repository and to protect the waste canisters from the surrounding rock.… read more here.

DOI: 10.1520/gtj20190026
Abstract: The effect of steam on the buffer material used in high-level radioactive waste (HLW) repositories has led to incessant uncertainty on the safety assessment because of the likelihood of loss in isolating potential. Hydraulic properties… read more here.
