Results and outcomes of the European Programme on Microbiology in Nuclear waste Disposal (MIND) - Views and perspectives over future research

A multidisciplinary EU-Project, denoted MIND, addresses key technical issues that must be tackled to support the implementation of planned geological disposal projects for radioactive wastes across the European Union.

Clay, crystalline and salt rock formations are considered as potential host rocks for the long-term storage of high-level radioactive waste in a deep geological repository. Particular microbial communities, which could influence the properties of the host rock or the materials used in the repository, are present in all three potential host rocks. Within the European Programme on Microbiology In Nuclear waste Disposal (MIND) the potential influence of natural occurring microorganisms within the bentonite buffer on the bentonite barrier itself, which is placed as a part of the multi barrier concept between the canister (containing the HLW) and the surrounding host rock is currently under investigation.

The understanding of the impact of microbial metabolism on the safety of geological repositories to date remains tenuous, even though microorganisms may be the controlling factor on the waste form evolution in situ, the multibarrier integrity and the ultimately radionuclide migration from the repository. The emphasis of the programme lies on quantifying specific impacts of microbial activity on safety cases under repository relevant conditions. The results of the MIND programme are leading to significant refinements of safety case models that are being implemented currently to evaluate the long-term evolution of radioactive waste repositories.

The MIND programme runs during four years, starting in June 2015.
