Description
oom Clay is considered as the natural barrier for the radioactive waste disposal, as it has a strong retention capacity for radionuclides. This migration of radionuclides is delayed thanks to the pore water geochemistry, as it determines de speciation and solubility of radionuclides. By now, the composition of the pore water is well known, but the mechanisms controlling the pCO2 and pH (which are key parameters in the migration are not yet understood). This research will provide information about the impact of the microbial communities in pore water-geochemistry (which plays a key role in the isolation of radionuclides) The isolation of methanogenic archaea is providing and will provide information regarding CH4 production, and the ongoing microbial mechanisms for its production All this new data can be used in the future by modelers to improve and validate the current geochemical model The optimization for the archaeal identification method will provide important knowledge to the archaeal research community in general.
