... for the long-term storage of nuclear waste. To this purpose, the IPSN installed an experimental site in a tunnel, which gives access to a 250 m-thick Toarcian and Domerian shale unit near Tournemire (Aveyron, France) (fig. 1). The fluids, in this type of rock with very low intrinsic permeability, 10 −14 m/s...

An industrial analogue for cement-clay interaction can be found at Tournemire, southern France, where boreholes filled with concrete and cement remained in contact with the natural mudstone...

... in the remainder of the current paper. Located on the southern border of the French Massif Central region, the Tournemire experimental platform is based around a tunnel built between 1882 and 1886 and several galleries which have been excavated since 2003 through Jurassic marls and mudstones. It now forms...

... and excavation of underground drifts that will cause both tunnel convergence ( Lisjak et al. 2015 ) and damage to the rock in the vicinity of the opening, with the formation of an associated excavated disturbed zone (EDZ) ( Armand et al. 2014 ). There are also numerous chemical effects as foreign materials like...

... will also affect barrier performance. The resulting thermal pulse around the waste can vary in duration from centuries, for reprocessed glass waste, to tens of thousands of years, for spent fuel. Water saturation and gas fluxes (CO 2 , H 2 ) are also expected to vary around disposal tunnels over time scales...
