Anas Sidahmed presents his research at DECOVALEX

Anas Sidahmed (DC8) presented the findings from his lab-scale simulation study to the DECOVALEX community. His results include a numerical simulation of surface deformation in large fractured GREAT cell samples during mechanical and hydraulic flow experiments. He participated in the DECOVALEX Task SAFENT-2.

The DECOVALEX project is an international collaboration that focuses on research and model comparison. Initiated in 1992, the project aims to enhance the understanding and modeling of coupled thermo-hydro-mechanical-chemical (THMC) processes in geological systems. Predicting these coupled effects is essential for evaluating the performance and safety of geological disposal systems for radioactive waste and spent nuclear fuel, as well as for various subsurface engineering activities.

Research teams involved in DECOVALEX are supported by several radioactive waste management organizations and regulatory authorities. These teams work collaboratively on selected modeling cases, followed by a comparative assessment of their results. This collaborative effort has resulted in a deeper understanding of THM and THMC processes related to nuclear waste repositories and broader geo-engineering applications, as well as the effectiveness of numerical simulation models for quantitative analysis.
