Abstract:
Abstract. After implementation of the Repository Site Selection Act (StandAG) in 2017,
the Federal Company for Radioactive Waste Disposal (BGE), as the German waste
management organization, started the site selection procedure for a nuclear
repository for high-level radioactive waste in Germany. On the way towards the
repository site with the best possible safety, the site selection procedure is
required to be a participatory, transparent, learning and self-questioning
process based on scientific expertise. With the Subareas Interim Report
published in 2020, first results were presented outlining subareas with
favourable geological conditions in preparation for defining the siting
regions for surface exploration. Currently, one of the main tasks in the site selection procedure is to
establish a detailed geoscientific synthesis (Geosynthesis) for each
subarea. The Geosynthesis contains all geological information for the
characterization of each subarea and hence serves as the foundation for the
subsequent analysis within the representative preliminary safety assessments
(rvSU) and the geoscientific consideration criteria. Based on this
information, all areas within the subareas will be evaluated to find the
siting regions for surface exploration. The Geosynthesis includes a description of the regional geology focusing on
the host rock, the overburden and relevant geological processes that may
affect the potential nuclear waste repository in the next 1 million years. The
data for the Geosynthesis are mostly compiled from state authorities and
include 3-D geologic models, regional maps and cross-sections, bore hole data
(e.g. geophysical logs) and seismic data. Furthermore, it is necessary to
digitize, process, interpret and evaluate the aforementioned data using the
available knowledge from the scientific literature in the context of the site
selection procedure.
