Abstract The potential for microbial activity to occur within the engineered barrier system (EBS) of a geological disposal facility (GDF) radioactive waste is acknowledged by management organizations as it could affect many aspects safety functions GDF. Microorganisms an EBS will be exposed changing temperature, pH, radiation, salinity, saturation, and availability nutrient energy sources, which can limit survival activity. Some limiting conditions are incorporated into GDF designs reasons, including high pH cementitious repositories, limited pore space bentonite-based or salinity GDFs in evaporitic geologies. Other environmental such elevated desiccation, arise result presence heat generating (HHGW). Here, we present comprehensive review how may activity, covering HHGW lower (LHGW) range environments. We data from literature on currently recognized limits life each described above, establish these Using examples where variable has been modelled particular GDF, outline times locations when that expected Finally, show this information multiple variables used improve our understanding and, more broadly, understand environments extreme conditions.

ABSTRACT The multi-national in situ Materials Corrosion Test (MaCoTe), being conducted at the Grimsel Site Switzerland, assesses stability of bentonite as it may be utilized within deep geological repositories (DGRs), which are proposed for safe, long-term disposal used nuclear fuel. This experiment provides an opportunity assessments changes microbial communities associated with compacted subsurface samples exposed to a natural groundwater. Leveraging from MaCoTe, herein, we report temporal data abundance and community composition microorganisms emplaced over 7 years under conditions. Phospholipid fatty acid analysis, 16S rRNA gene quantification sequencing, cultivation, organic matter analyses all indicated no significant abundances inner layers years. While did not change layers, PLFA suggest potential could also indicate prolonged turnover rates. Overall, results support DGR-like conditions least IMPORTANCE Long-term activity low-biomass systems analogous (DGRs) critical test stable engineered barrier components. study bentonites It offers 7-year that bentonite-based materials intended use DGR fuel, wider implications persistence environment.
