1. Radioactive Waste Repository Authority (Czech Republic)

The Czech Republic's deep geological repository (DGR) policy sets out a number of important milestones including the selection of candidate sites by 2018 and the selection of a final site by 2025. The final commissioning of the Czech DGR is planned for 2065. In 2010 a screening process was completed employing geological and other criteria that resulted in the identification of 7 potentially suitable sites, all situated in crystalline - granite host rock environments. The next step of the process will result in a reduction both in the number of sites and the surface area of remaining sites based on preliminary safety evaluations and socioeconomic, political and environmental criteria. In order to better understand the behaviour of crystalline host rock environments for DGR safety case purposes, the Radioactive Waste Repository Authority (RAWRA) made decided to enhance the extent of in-situ measurements and research at a depth corresponding to that of the future DGR. In the second half of 2013, RAWRA commenced the construction of the Bukov Underground Research Facility (Bukov URF) in the southern section of the Rozna uranium mine at a depth of 600 m below the earth's surface in a geologically well-mapped area of a Moldanubic crystalline rock formation which is composed principally of migmatised gneisses, migmatites and granulites. The Bukov URF will be, first and foremost, a research facility at which work will be conducted focusing on the taking of geophysical measurements, petrographic, mineralogic, geochemical research and the in-situ determination of the physical - mechanical, geochemical and hydrogeological properties of the host rock massif. The research results will form input data which will be used to both support and improve the safety of the future DGR. (authors)
