Short summary
The German site selection procedure to identify a site for the disposal of high-level radioactive waste is ongoing. The current step of the procedure includes representative preliminary safety analyses, for which the methodology is described and a first insight on the implementation is given. We aim to provide a document to boost communication and discussion with the scientific community and the public, although the implementation is at an early stage and may be subject to numerous changes.

Crystalline rocks are being considered as potential host rocks in the ongoing search for a suitable site for a nuclear waste repository in Germany, where there is no existing experience in terms of excavating a repository in crystalline rocks. The planned underground laboratory GeoLaB addressing crystalline geothermal reservoirs offers unique opportunities for synergies with nuclear waste disposal research and development, especially in the exploration and building phases.

The preliminary representative safety analyses in Phase I, Step 2 of the site selection procedure for the disposal of high-level radioactive waste in Germany requires, according to Section 7 (6) No. 4 EndlSiUntV, that
the basic possibility of safe operation shall be demonstrated but that a complete operational safety analysis does not need to be performed. This paper provides a summary of the methodology developed by the Bundesgesellschaft für Endlagerung (BGE) on this topic.

We present CobWeb 1.0, a graphical user interface for analysing tomographic images of geomaterials. CobWeb offers different machine learning techniques for accurate multiphase image segmentation and visualizing material specific parameters such as pore size distribution, relative porosity and volume fraction. We demonstrate a novel approach of dual filtration and dual segmentation to eliminate edge enhancement artefact in synchrotron-tomographic datasets and provide the computational code.

Short summary
Machine learning techniques are a promising alternative for processing (phase segmentation) of 3-D X-ray computer tomographic rock images. Here the performance and accuracy of different machine learning techniques are tested. The aim is to classify pore space, rock grains and matrix of four distinct rock samples. The porosity obtained based on the segmented XCT images is cross-validated with laboratory measurements. Accuracies of the different methods are discussed and recommendations proposed.

Short summary
The German search for a disposal site for high-level nuclear waste is in its first phase. In the so-called
representative preliminary safety assessmentsthe possible future evolutions of potential disposal sites will be developed from our understanding of their past evolution. Erosion processes connected to glaciations can reach especially deep and could threaten a repository, while being very hard to predict. This makes them important to the site selection process.
The German search for a disposal site for high-level nuclear waste is in its first phase. In the...
