Introductory editorial to the special issue on the DECOVALEX-THMC project

An important part of the performance and safety assessment of disposal systems for radioactive waste and spent nuclear fuel in deep geological formation is to evaluate the impact on repository performance due to the coupled effects of rock mechanical deformation, groundwater flow through the repository, and thermal loading from the decaying waste. It was recognized that to be able to conduct such an evaluation, there is a need to enhance the theoretical background and to develop models capable of simulating coupled thermo-hydro-mechanical (THM) processes. More recently, chemical (C) processes have also been added to the coupled THM models to enable the study of fully coupled THMC processes in geosystems.

In 1992, recognizing the need to address this rather difficult but important problem of coupled THM and THMC processes, the Swedish Nuclear Power Inspectorate (SKI; recently reorganized and renamed Swedish Radiation Safety Authority, SSM) initiated an international cooperative project...
