Description: Summary Sub-areas Interim Report according to Section 13 StandAG As per 28/09/2020 Ref.: SG01101/16-1/2-2020#30 – Object ID: 830270 – Revision: 000 Summary Sub-areas Interim Report according to Section 13 StandAG In 2013, the German Bundestag and Bundesrat have passed a law to restart the search for the site with the best possible safety for a repository for the high-level radioactive waste produced in Germany. The “Commission on the Storage of High-level Radioactive Waste”, consisting of representatives of science, the German Bundestag and Bundesrat as well as associations, worked until 2016 on a concept for the site selection procedure based on the white map of Germany. For this purpose, the Commission developed rules, criteria and formulated requirements on a repository for high-level radioactive waste. The legislator passed the “Act on the search and selection of a site for a repository for high- level radioactive waste” (Site Selection Act – StandAG) in May 2017, which was based on the findings of the Commission. The Site Selection Act describes the principles science-based, participative, transparent, self-questioning and learning. The search area will be narrowed down increasingly over the course of three phases: starting with the entire federal territory; then surface exploration regions and subsurface exploration of sites; and finally a proposal for a repository site offering the best possible safety to accommodate high-level radioactive waste. The Bundesgesellschaft für Endlagerung mbH (BGE) is responsible for the site selection procedure as the German Waste Management Organisation. In this Interim Report, the BGE is presenting first results outlining sub-areas in preparation for defining the site regions. For final disposal, the BGE considers the host rocks rock salt, clay rock and crystalline rock within the framework of the work in accordance with section 13 StandAG and section 1(3) StandAG. According to Section 13 StandAG, sub-areas describe the areas in Germany where favourable geological conditions can be expected for the safe final disposal of high-level radioactive waste in one of the three possible host rocks. They are identified by the application of the geoscientific requirements and criteria that are legally stipulated in Section 22 StandAG (exclusion criteria), Section 23 StandAG (minimum requirements) and Section 24 StandAG (geoscientific weighting criteria). With this Sub-areas Interim Report, the BGE makes a contribution to engender the necessary public interest in the issue of final disposal and the site selection procedure. The Sub-areas Interim Report provides the basis for the Conference on Sub-areas and encourages participation. Hence, publication of the Sub-areas Interim Report lays the foundation to start the formal public involvement process at a stage that is sufficiently early to enable influence on the work and the findings of the site selection procedure. In order to ensure transparency in the decision-making process, this Interim Report and the supporting documents present the findings and all facts and considerations that are relevant to selection. The site selection procedure was launched in September 2017, and the BGE has started to work on it. Enquiries were sent to the federal and state authorities to obtain the data sets required to apply the legally stipulated geoscientific requirements and criteria throughout Germany. This Interim Report and its supporting documents describe the Geschäftszeichen: SG01101/16-1/2-2020#30 – Objekt-ID: 830270 – Revision: 000 2 Summary Sub-areas Interim Report according to Section 13 StandAG methods and their development. The general public and experts were involved in the process of preparing the application methods. In addition, the BGE discussed its application methods in public during online consultations that were held between November 2019 and August 2020. Some of the information obtained during these discussions prompted an adjustment of the application methods. During the process of identifying the sub-areas, a first step involved excluding areas that are unsuitable as repository sites for high-level radioactive waste according to the legally defined exclusion criteria according to Section 22 StandAG. The exclusion criteria include large-scale vertical movements, active fault zones, influences from current or past mining activities, seismic activity, volcanic activity and young groundwater age. The rules set out in Section 22(1) StandAG state that an area is classified as unsuitable as soon as one of the defined exclusion criteria applies. The next step involved an assessment of the remaining areas to determine which ones meet the minimum requirements of Section 23 StandAG. First of all, rock formations were identified which contain clay rock, rock salt and crystalline host rock types relevant to repositories. The minimum requirements refer to the hydraulic conductivity of the rock, the thickness of the effective containment area, the minimum depth of the effective containment area (i.e. its distance to the earth’s surface), the assumed minimum area of the repository and the preservation of the barrier effect. “Identified areas” that satisfy none of the exclusion criteria according to Section 22 StandAG and all of the minimum requirements according to Section 23(2) StandAG were obtained as a result of these two steps. In the third step, these identified areas will be evaluated according to the geoscientific weighing criteria defined in Section 24 StandAG in regard to their favourable overall geological situation and hence their suitability as a repository site for high-level radioactive waste. The geoscientific weighing criteria described in Annexes 1 to 11 (to Section 24) StandAG are used as evaluation benchmarks. These eleven criteria refer to the •transport of radioactive substances by groundwater movements in the effective containment zone; •configuration of the rock bodies; •spatial characterisability; •long-term stability of the favourable conditions; •geomechanical properties; •tendency to form fluid pathways; •gas formation; •temperature compatibility; •retention capacity in the effective containment zone; •hydrochemical conditions; and •protection of the effective containment zone by the overburden.
