Site Selection & Site Characterisation

Site selection and site characterisation require a reliable data base, scientific rigour and a safety assessment with a long-term perspective.

Request advice on site selection and characterisation

The selection of a suitable site for a final repository for radioactive waste is a decision with far-reaching implications. It must be based on scientific findings, reliable data and a systematic assessment of the relevant framework conditions. The aim is to ensure the safe isolation of radioactive waste from the biosphere over very long periods of time. 

To this end, geological, hydrological, geotechnical and infrastructural factors must be carefully analysed and assessed within the overall context. DMT supports authorities and public bodies in the systematic site selection and site characterisation process throughout all phases of the selection process, drawing on its geoscientific expertise and regulatory knowledge. 

Our range of services

Geophysical and geological exploration

Site selection begins with the systematic collection and analysis of reliable data. DMT plans and oversees geophysical and geological surveys in order to systematically record and evaluate the characteristics of potential sites. 

  • Carrying out geophysical and geological surveys
  • Collection and analysis of site-relevant data
  • Support with the planning of investigation programmes
  • Technical interpretation of the results within the selection process 

Analysis of host rocks

The properties of the host rock are crucial to the long-term safety of a final repository. DMT analyses the suitability of potential host rocks and assesses their geological and geotechnical characteristics with a view to the safe disposal of radioactive waste. 

  • Analysis of host rocks with regard to final repository requirements
  • Assessment of geological and geotechnical properties
  • Comparison of site-specific potential and constraints
  • Integration into safety-oriented overall concepts 

Assessment of long-term safety

A final repository must function effectively over very long periods of time. For this reason, the assessment of long-term safety is a key component of site characterisation. DMT provides support in the systematic derivation and evaluation of safety-relevant criteria. 

  • Assessment of long-term safety
  • Structured analysis of potential development pathways and risks
  • Support in deriving safety-relevant requirements
  • Technical involvement in final repository concepts and justifications 

Geological and regulatory framework

The suitability of a site does not depend solely on its geological characteristics. Legal, methodological and procedural requirements must also be taken into account at an early stage. DMT assesses the relevant geological and regulatory framework conditions in relation to site selection. 

  • Assessment of geological and regulatory framework conditions
  • Support in the context of the Site Selection Act (StandAG) and the Atomic Energy Act (AtG)
  • Taking into account relevant requirements arising from nuclear regulatory procedures
  • Classification of specialised requirements, such as those set out in the Ordinance on Safety Requirements for Final Repositories (EndlSiAnfV)

Frequently Asked Questions on Site Selection and Site Characterisation

DMT provides support not only with technical planning, but also with the design, coordination and technical supervision of investigation work. Depending on the project requirements, field-based services can also be incorporated into the overall project management.

DMT has extensive expertise in geological, geophysical and mining engineering matters, as well as in the planning and assessment of complex projects relating to the final disposal of radioactive waste. We apply this experience to both national and international projects. 

DMT combines expertise in the geosciences and engineering with a structured understanding of regulatory requirements. This enables us to take a holistic view of site selection and site characterisation and to develop robust decision-making frameworks that transcend disciplinary boundaries.
