From March 15 – 19, 2017, the 3rd Sino-German Workshop on Radioactive Waste Disposal, organised by CNNC (China National Nuclear Cooperation) and BRIUG (Beijing Research Institute of Uranium Geology) as well as BGR (Federal Institute for Geosciences and Natural Resources, Germany) and PTKA (Project Management Agency Karlsruhe – Karlsruhe Institute of Technology, Germany), took place in Jiayuguan, China. Numerous research institutions and universities from China and Germany were invited to the conference to discuss a variety of topics, like site selection, repository concepts and technology, modelling, experiments, and safety case aspects. DBE TECHNOLOGY GmbH participated and gave a well-received and appreciated presentation about concepts and emplacement technologies for an HLW repository in Germany. The conference was a very valuable place to learn. Especially with regard to ongoing and future R&D work for radioactive waste disposal in crystalline rock in Germany, DBE TECHNOLOGY GmbH will very much benefit from the practical experience made in China, for example in the areas of drilling and blasting, TBM tunnelling and grouting.
As a conference highlight, the attendees visited the “Beishan Exploration Tunnel“ (BET) in the Beishan Area of the Gobi Desert. This tunnel was an underground testing site in granite rock for validating the technologies that will be employed in the construction of the future underground laboratory at a site approximately 30 km away from the BET. The construction of the BET itself took place in 2015. Today, the experiments are already completed.
Within the scope of the existing cooperation agreement between DBE TECHNOLOGY GmbH and BRIUG, we look forward to learning more about the experience BRIUG will make in the Chinese Repository Program.
