A Synthesis of Approaches for Modelling Coupled Thermal–hydraulic–mechanical–chemical Processes in a Single Novaculite Fracture Experiment

Original language description

The geological formation immediately surroundinga nuclear waste disposal facility has the potentialto undergo a complex set of physical and chemical processesstarting from construction and continuing manyyears after closure. The DECOVALEX project (DEvelopmentof COupled models and their VALidation againstEXperiments) was established and maintained by a varietyof waste management organisations, regulators andresearch organisations to help improve capabilities inexperimental interpretation, numerical modelling and blindprediction of complex coupled systems. In the present round of DECOVALEX (D-2015), one component of TaskC1 has considered the detailed experimental work ofYasuhara et al. (Earth Planet Sci Lett 244:186–200, 2006),wherein a single artificial fracture in novaculite (micro- orcrypto-crystalline quartz) is subject to variable fluid flows,mechanical confining pressure and different applied temperatures.This paper presents a synthesis of the completedwork of six separate research teams. A range of approachesare presented including 2D and 3D high-resolution coupledthermo–hydro–mechanical–chemical models. The resultsof the work show that while good, physically plausiblerepresentations of the experiment can be obtained using arange of approaches, there is considerable uncertainty inthe relative importance of the various processes, and thatthe parameterisation of these processes can be closelylinked to the interpretation of the fracture surface topographyat different spatial scales.
