Hydrogeology and Groundwater Management in a Coastal Granitic Area With Steep Slopes in Galicia (Spain)
(Springer, 2021)
[Abstract] Groundwater availability, management and protection are great challenges for the sustainability of groundwater resources in the scattered rural areas of the Atlantic regions of Europe where groundwater is the ...
Modelling of the long-term evolution and performance of engineered barrier system
(EDP Sciences, 2022)
[Abstract:] Components of the so-called “multiple-barrier system” from the waste form to the biosphere include a combination of waste containers, engineered barriers, and natural barriers. The Engineered Barrier System ...
A non-isothermal reactive transport model of the long-term geochemical evolution at the disposal cell scale in a HLW repository in granite
(Elsevier, 2023)
[Abstract:] The assessment of the long-term performance of the engineered barrier systems of high-level radioactive waste (HLW) repositories requires the use of reactive transport models. Here a non-isothermal reactive ...
Reactive transport modelling of a low-pH concrete / clay interface
(Elsevier, 2020)
[Abstract:] Cement-based materials are key components in the barrier system and structural support of repositories for disposal of nuclear waste. As such, increased understanding of their long-term performance under ...
Coupled THCM model of a heating and hydration concrete-bentonite column test
(Elsevier, 2018)
[Abstract:] Radioactive waste disposal in deep geological repositories in clay formations envisage a compacted bentonite engineered barrier and a concrete liner. The alkaline conditions caused by the degradation of concrete ...
Long-term non-isothermal reactive transport model of compacted bentonite, concrete and corrosion products in a HLW repository in clay
(Elsevier, 2017)
[Abstract:] Radioactive waste disposal in deep geological repositories envisages engineered barriers such as carbon-steel canisters, compacted bentonite and concrete liners. The stability and performance of the bentonite ...
Reactive transport modelling of the long-term interactions of corrosion products and compacted bentonite in a HLW repository in granite: Uncertainties and relevance for performance assessment
(Elsevier, 2016)
[Abstract:] Here we present a long-term nonisothermal reactive transport model for the interactions of the corrosion products of a carbon-steel canister and the compacted bentonite of the engineered barrier of a high-level ...
Reactive transport models of the geochemical interactions at the iron/bentonite interface in laboratory corrosion tests
(Elsevier, 2023)
[Abstract:] Carbon steel and compacted bentonite have been proposed as candidate materials for the overpack and buffer, respectively, of the multi-barrier system of a geological high-level radioactive waste repository. ...
A revisited thermal, hydrodynamic, chemical and mechanical model of compacted bentonite for the entire duration of the FEBEX in situ test
(Elsevier, 2018)
[Abstract:] The safety assessment of geological repositories for radioactive waste requires quantifying the geochemical evolution of the engineered clay barriers where thermal (T), hydrodynamic (H), mechanical (M) and ...
Dynamic update of flow and transport parameters in reactive transport simulations of radioactive waste repositories
(Elsevier, 2020)
[Abstract:] The changes in porosity caused by mineral dissolution/precipitation and the associated changes in flow, transport and chemical parameters of porous and fractured media are relevant for the geochemical time-evolution ...
