The preliminary safety analysis at the Gorleben site, is a GRS research project. GRS assumes responsibility for the organisation and scientific management of the project sponsored by the Ministry for the Environment, and is involved in the undertaking of the main body of work.
As the ‘Preliminary Safety Analysis’ requires a diverse number of specialist expertise, various project partners have teamed up with GRS. These include: Dr. Bruno Baltes, the Federal Institute for Geosciences and Natural Resources (BGR), the DBE Technology GmbH, the Institute for Mineral and Waste Processing, Landfill Technology and Geomechanics at TU Clausthal, the Institute of Disposal Research at TU Clausthal, the Institute for Rock Mechanics GmbH (IfG), the Institute for Safety Technology (ISTec), the Karlsruhe Institute for Technology /Institute for Nuclear Waste Disposal (KIT/INE), International Nuclear Safety Engineering GmbH (NSE), (several institutes from RWTH in Aachen), as well as the Institute for Atmospheric and Environmental Sciences (IAU) at the University of Frankfurt.
Institute for Geosciences and Natural Resources (BGR)
The BGR is the central advisory institute of the Federal Government providing information on all geosciences and raw material related issues. The BGR is a specialist institute of the Federal Ministry of Economics and Technology. All of the various themes pertaining to geosciences as well as radioactive waste disposal are covered in research and consulting by the BGR. The BGR has established studies on the potential suitability of possible siting regions of geological host rocks in Germany. The BGR were essential to the planning, execution and evaluation of the site at Gorleben. They worked on the underground exploration and published the results of numerous geological site descriptions about Gorleben.
DBE TECHNOLOGY Ltd
DBE TECHNOLOGY GmbH is an engineering and consultant corporation, which works internationally, providing support and advice on disposal of nuclear waste, consulting those authorities, amongst others, who actively work with energy, waste management and mining companies. The know-how of the company is based on 30 years of experience in planning, construction and operation of repositories both nationally and internationally. DBE is involved in a wide array of projects, from geoscience and engineering investigations, complex numerical model calculations to operational planning and safety technology valuations. In the VSG project, DBE Technology contributes greatly with, amongst other things, its experience in the fields of repository concepts, checking geotechnical barriers as well as developing scenarios.
The Institute for Atmospheric and Environmental Sciences (IAU)
The Institute for Atmospheric and Environmental Sciences (IAU) is one of the concentrations of the Faculty 11 ‘Mankind and the Environment’ at the Johann Wolfgang Goethe University of Frankfurt. The institute has five research groups: Aerosol and Environmental Science, Experimental Atmospheric Research, Mesoscale Meterology and Climate, Theory of Atmospheric Dynamics and Climate and Analytical Environmental Chemistry. With help of experimental, theoretical and modeling research, the understanding of physical and chemical processes in the atmosphere can be improved and passed on.
Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) mbH
Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) is an independent, non-profit research and expert organisation. GRS researches and examines in the fields concerning reactor safety, waste management and radiation protection. The VSG project is GRS’s own research project working with various commissioned project partners. GRS is the project leader and manages the predominant part of the work. The company’s work includes, amongst other things, competence in the areas long-term safety, repository concepts, waste characterisation, scenario development, release scenarios and the analysis of possible consequences.
The Institute for Rock Mechanics GmbH (IfG)
The Institute for Rock Mechanics GmbH (IfG) was founded in 1990 from the former Institute for Mining Safety in Leipzig. It leads in scientific-technical fundamental research as well as practical investigations and examines geomechanical problems, with priority in salt mining and underground storage in caverns. It has many years of experience in the evaluation of stability convergence behaviour of complex pits in various geological formations. Based on this, the IFG contributes to the VSG project above all with thermomechanical simulation calculations to evaluate the geomechanical integrity of the geological barriers.
The Institute for Safety Technology (ISTec)
At the Institute for Safety Technology (ISTec) around 40 scientists and technicians research and develop with many years of national and international experience. ISTec is a subsidiary of GRS. The institute consults, amongst other things, plant manufacturers, plant operators, processing industry, transport services and the authorities in diagnostics and safety-related questions. ISTec combines decades of experience in research, development, implementation and testing of safety technology. ISTec advises and examines the introduction of new technology, offers a comprehensive service in operation and use as well as integrated technical solutions. In the VSG project, ISTec offers its expertise in keeping records of waste flow and waste characterisation.
The Karlsruhe Institute for Technology (KIT)
The Karlsruhe Institute for Technology (KIT) is a merger of the research centre with the University of Karlsruhe. The Institute for Nuclear Waste Disposal (INE) deals with methods for a scientific well-founded proof of long-term safety of repositories on a geochemical approach. The work concentrates on actinides and durable fission products and ranges from fundamental laboratory tests in geochemistry of actinides in an aquatic system, retention on surfaces, the development and adaptation of speciation methods up to application-orientation investigations of radionuclide retention in multi-barrier systems. In the VSG, KIT-INE calculates the concentration of radionuclides that become mobilized from spent nuclear fuel or from vitrified highly radioactive waste.
Nuclear Safety Engineering International (nse) GmbH
Nuclear Safety Engineering International (nse) GmbH is based in Aachen and was founded in 2010. nse offers engineering and consulting services in the fields of final and intermediate storage of radioactive waste, waste management, plant monitoring and automation as well as mechanical engineering and extraction technology above and below ground. In the VSG, nse are specialists in the judging of quality and validity of the geoscientific sites in addition to being involved in the design of the technical repository and optimisation with respect to the retrieval of waste containers.
The Institute for Repository Research at the TU Clausthal carries out interdisciplinary research to answer questions about site characterisation, site exploration of the geotechnical safety systems and the long-term safety case. The research group 'geochemistry' deals i.a. issues of salt geology. The research group ‘respository system’ deals with issues about the procedure of furnishing proof for the long-term safety of repositories for radioactive waste in deep geological formations. The professorship ‘landfill technology and geomechanics’ at the Institute for Treatment, Landfill Technology and Geomechanics deals with, amongst other things, the safety of underground sealing structures and supporting systems, based on numeric simulation and experiments . The TU Clausthal contributes to the VSG as an independent external expert and checks the quality of the results.
