||Develop a common report on the lessons learned from in-situ experiments on the behaviour of bentonite. (Topic 3.2 in the SRA)
Explanation of the contents of the activity :
Useful input to the LUCOEX work.
The different experiments that have been undertaken on the behaviour of bentonite :
- At Mt Terri, HE-C (on the coupled thermo-hydro-mechanical (THM) processes developed in a clay host rock and a bentonite buffer), EZ-A (Testing of hydraulic stops in the host rock), ED-FE
- At Aspö, LOT (on the changes induced on Bentonite by thermal effects), ABM (on the alternative materials to MX 80 bentonite), TBT (behaviour of a bentonite + sand EB), prototype repository
- At Bure MAG (interaction between host rock and disposal materials)
- At URL, TSX (drift seal experiment), shaft sealing
- At Grimsel, EGTS
- At MOL, Praclay
- And no doubt others...
