A story posted on the Swiss news site www.swissinfo.ch provides an interesting additional detail to the information regularly provided by the NWMO about the project. The NWMO regularly references the Swiss underground research project and their involvement, and in some instances includes the detail that studies involve Opalinus Clay, but in no instances found in our search of NWMO documents did the NWMO clarify that the laboratory itself is located in a broad band of Opalinus Clay, and not in a rock formation similar to those found at any sites the NWMO is investigating in Canada.
“Nuclear waste is no match for ancient rock”, By Celia Luterbacher, St Ursanne, as posted on Swissinfo.ch
A special type of clay found beneath Swiss soil could solve the dilemma of what to do with the thousands of cubic metres of waste that will remain after Switzerland’s five nuclear power plants shut down.
If you join one of the subterranean tours at the Mont Terri Rock Laboratory in St Ursanne, canton Jura, the first thing you will see as you make the 300-metre descent is a dark tunnel lined with seeping, moist rock.
Go on a bit further, and suddenly the walls of the tunnel become bone dry. This marks the geological transition between limestone and Opalinus Clay – and for the Mont Terri Project (MTP) scientists, it’s as good as striking gold.
