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 ...
Conceptual and numerical models of solute diffusion around a HLW repository in clay
(Elsevier, 2011)
[Abstract:] Reactive transport models have been used to simulate solute diffusion, canister corrosion, interactions of the corrosion products with the bentonite and the long-term hydrochemical evolution of porewater ...
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. ...
The DI-B in situ diffusion experiment at Mont Terri: Results and modeling
(Elsevier, 2008)
[Abstract:] The diffusion experiment “DI-B” aimed at studying the transport and retention properties of selected non radioactive tracers in the Opalinus Clay (shaly facies) at the Mont Terri URL. Selected tracers were: 2H ...
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 ...
Groundwater Flow Model along a Vertical Profile of the Sardas Landfill in Sabiñánigo, Huesca, Spain
(MDPI, 2023)
[Abstract:] Lindane (a harmful contaminant) was produced in Sabiñánigo (Huesca, Spain) and deposited at the Sardas landfill. This site contains a large mass of pollutants, which have an extremely large contamination potential ...
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 ...
Macro-Scale Spatial Modeling Reveals the Role of Soil Organic Matter Quality in CO2 Emissions
(Elsevier, 2023-08-04)
[Abstract] Carbon dioxide (CO2) emissions from agricultural soils result from the interaction of various factors that regulate the quantity and quality of organic material. Our objective was to assess changes in soil CO2 ...
New Insights Into the Production, Characterization and Potential Uses of Vineyard Pruning Waste Biochars
(Elsevier, 2023-10-04)
[Abstract] Vineyard pruning waste (VP) can be converted into a useful char using pyrolysis as part of a valorization strategy. This study analyzed the effect of temperature (300 and 600 °C) and residence time (1 and 3 h) ...
Impact of pig slurry application on soil and water losses: comparison with a historical series
(Universidade Federal de Campina Grande, 2019-04-30)
[Abstract] Water erosion in soil is influenced by several factors, including rain, relief, cover, and management and conservation practices. Also, erosion is affected by pig slurry (PS) applied to the soil as a fertilizer. ...
