iCross: Integrity of nuclear waste repository systems - Cross-scale system understanding and analysis


Financed by:
Federal Ministry of Education and Research (02NUK053B)
 
Helmholtz Association of German Research Centres (SO-093)
Period:
2018/07 – 2022/03
Cooperation partners:
  • Forschungszentrum Jülich (FZJ) (coordinator)
  • Helmholtz Centre Potsdam – German Research Centre for Geosciences (GFZ)
  • Helmholtz-Zentrum Dresden-Rossendorf (HZDR)
  • Karlsruhe Institute of Technology (KIT)
  • Helmholtz Centre for Environmental Research (UFZ Leipzig)

Short Project Description:

The interdisciplinary project "iCross" bundles research and development expertise in the Helmholtz Association on the subjects of radiochemistry, geosciences, life sciences and numerical simulations of environmental systems in a cross-research project. Processes that have not been fully understood from the molecular to the regional scale are examined, evaluated and described. The aim is to plan and carry out laboratory experiments, to derive parameters and to model relevant processes across scales using advanced simulation methods (that require several numerical upscaling treatments). The simulations are validated experimentally, partly in underground laboratories. The focus here is on work in the Mt. Terri rock laboratory (CH; Opalinus clay), where a new test tunnel is being excavated with the strong participation of German partners. Further investigations take place in the Grimsel rock laboratory (CH; crystalline rock). The work focuses on host rocks (crystalline and clay), which were not the major focus of German repository research in the past.
