Abstract: | The DECOVALEX project is a unique international research collaboration, initiated in 1992, for advancing the understanding
and mathematical modelling of coupled thermo-hydro-mechanical (THM) and thermo-hydro-mechanical-chemical (THMC) processes
in geological systems—subjects of importance for performance assessment of radioactive waste repositories in geological formations.
From 1992 up to 2007, the project has made important progress and played a key role in the development of numerical modelling
of coupled processes in fractured rocks and buffer/backfill materials. The project has been conducted by research teams supported
by a large number of radioactive-waste-management organizations and regulatory authorities, including those of Canada, China,
Finland, France, Japan, Germany, Spain, Sweden, UK, and the USA. Through this project, in-depth knowledge has been gained
of coupled THM and THMC processes associated with nuclear waste repositories, as well as numerical simulation models for their
quantitative analysis. The knowledge accumulated from this project, in the form of a large number of research reports and
international journal and conference papers in the open literature, has been applied effectively in the implementation and
review of national radioactive-waste-management programmes in the participating countries. This paper presents an overview
of the project. |
