“…A series of laboratory tests have been performed by the German partners under Joint Project III on WIPP salt from salt core provided by the U.S. Results from this testing program have been reported by Salzer et al (2015) and Düsterloh et al (2015). The laboratory testing program conducted by the Germans on WIPP salt indicated that there were only minor differences in the mechanical behavior (creep response) of clean vs. argillaceous WIPP salt.…”

Sandia is participating in the third phase of and is a contributing partner to a U.S.-German "Joint Project" entitled "Comparison of current constitutive models and simulation procedures on the basis of model calculations of the thermo-mechanical behavior and healing of rock salt." The first goal of the project is to check the ability of n umerical modeling tools to correctly describe the relevant deformation phenomena in rock salt under various influences. Achieving this goal will lead to increased confidence in the results of numerical simulations related to the secure storage of radioactive wastes in rock salt, thereby enhancing the acceptance of the results. These results may ultimately be used to make various assertions regarding both the stability analysis of an underground repository in salt, during the operating phase, and the long-term integrity of the geological barrier against the release of harmful substances into the biosphere, in the post-operating phase. Among the numerical modeling tools required to address this are constitutive models that are used in computer simulations for the description of the thermal, mechanical, and hydraulic behavior of the host rock under various influences and for the long-term prediction of this behavior into the future. A second goal of the project is to investigate and demonstrate the possibilities for further potential development and improvement of these constitutive models. This report summarizes the efforts undertaken during FY15 in support of this international U.S.-German benchmark initiative. Results from the US-German Benchmark Initiative for FY15 August 2015 v ACKNOWLEDGMENTS The author wishes to acknowledge John F. Holland, James E. Bean, and Jonathan S. Rath for their contributions to the various efforts during FY2014 and prior years. The dedication of this team, in the face of many challenges, has been outstanding. Special thanks also to Frank Hansen and Andrew Orrell (now with IAEA) for their support and encouragement in promoting this important international collaboration.

“…A vast suite of laboratory tests recently completed on WIPP salt tends to modify this generalization. In fact, compressive strength of WIPP bedded salt and Speisesalz from the Asse dome are comparable, while the WIPP salt creeps a little faster (Salzer et al 2015). Figure 4-5 illustrates strength and dilatancy boundary similarity of these two, well-characterized salts.…”
