9th International Conference on Clays in Natural and Engineered Barriers for Radioactive Waste Confinement (Clay Conference) 2024 in Hanover, Germany from November 25th to 28th 2024, February 26, 2024 In cooperation with the Federal Institute for Geosciences and Natural Resources (BGR), the German Federal Agency for Nuclear Waste Disposal (BGE) is hosting the 9th International Conference on Clays in Natural and Engineered Barriers for Radioactive Waste Confinement (Clay Conference) in Hanover in 2024. First organised in 2002 by the French project promoter ANDRA (Agence Nationale pour la Gestion des Déchets Radioactifs), the international conference offers experts from all over the world and from various disciplines and organisations a scientific platform to deal with various aspects of clay host rocks and barriers to the management of radioactive waste in clay and clay rocks, and to learn about the research and development of radioactive waste in clay and clay rocks and exchange views on the progress of research in this field.The aim of the Clay Conference conference series is to discuss the current research results on the properties and suitability of clay host rocks and clay geotechnical barriers, to compare knowledge internationally and to continuously deepen it. The conference from 25th to 28th November 2024 at the Hanover Congress Centrum (HCC) will focus on lectures and poster presentations. On 24th and 29th November, a supplementary supporting programme with workshops and excursions is planned. |

Repositories in crystalline host rock: An overview of site selection procedures, data aquisition and modelling (BGR), December 1, 2023 According to § 1 of the Site Selection Act (StandAG), in addition to rock salt and clay rock, crystalline rock is also considered as host rock for the final disposal of high-level radioactive waste in Germany. For the implementation of the StandAG, detailed information on the structural geology and the barrier properties of potentially suitable crystalline host rocks in Germany is therefore required. The current report of the BGR's DaFNe Research and Development project describes the basics of a workflow for a systematic survey of the distribution, formation and properties of fractures and fault zones, and for transferring these datasets into a geostatistical model. This will allow numerical analyses as are required within the context of safety cases. For this purpose, site selection procedures and development stages in identified countries are provided where repositories in crystalline host rock are planned or implemented and fundamentals of the formation and interpretation of fractures are outlined. This report presents the individual steps from the acquisition of raw data to the creation of a representative Discrete Fracture Network (DFN) or continuum model. It provides compilations of possible survey methods for geometric data collection of fractures in outcrops, and of the input parameters required for modelling. Furthermore, the key equations required for modelling groundwater flow in fractured porous media material in the subsurface are outlined. |
