13:30 Topical Session
-Consolidation of Crushed Salt and its relevance for the Safety Case-
Topical Session Chair: Wilhelm Bollingerfehr, DBE TECHNOLOGY
Aims:
 Summarize the state of the art on the understanding of the processes that govern
the crushed salt consolidation and determine the relevance of crushed salt as
geotechnical barrier in a repository for radioactive waste
 Display in detail the experiences gained by laboratory tests and in-situ tests on
crushed salt
 Discuss and compile the R&D-needs to accomplish the scientific basis for crushed
salt as an important component of a technical barrier in a HLW repository
13:30 3.1 I
Crushed salt as important element of technical barriers in a
HLW-repository (operating conditions of crushed salt
backfill and their relevance for repository safety)
Nina Müller-Hoeppe, DBE TECHNOLOGY GmbH
14:00 3.2 I
Material behaviour: Experiences gained in in-situ tests on
crushed salt (in particular investigations on wetted crushed
salt); a comparison of the mechanical behaviour of dry and
wetted crushed salt
