... for several years to test the feasibility of realization and the behavior of disposal cells for high level – long life waste packages. Within the framework of this program, and as part of the European project LUCOEX (Large Underground Concept Experiment), a new phase has started at the end of 2012...

... Abstract At the Meuse/Haute Marne Underground Research Laboratory, Andra has developed a technical and scientific program to test the feasibility of excavation of disposal cells for nuclear waste in a 500 m deep clay formation. Five micro-tunnels, 20 m long and 74 cm diameter will be excavated...

... and its variation along the alignment of a tunnel. Variation of the thickness of the shotcrete support and the internal lining for the predicted ground conditions is easily feasible, because it is possible to change the excavation diameter along the alignment.lt is also possible to increase and decrease...

... ABSTRACT: In preparation for the construction of a new underground facility at CERN, a programme of 3D finite element analysis was carried out to assist in assessing the feasibility of constructing the complex series of interconnecting caverns, shafts and tunnels. The paper describes the rock...
