A non-isothermal reactive transport model of the long-term geochemical evolution at the disposal cell scale in a HLW repository in granite
Montenegro, Luis; Samper, Javier; Mon, Alba; De Windt, Laurent; García, Enrique; Samper, Aurora C. (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 ... -
A revisited thermal, hydrodynamic, chemical and mechanical model of compacted bentonite for the entire duration of the FEBEX in situ test
Samper, Javier; Mon, Alba; Montenegro, Luis (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 ... -
Coupled THCM model of a heating and hydration concrete-bentonite column test
Samper, Javier; Mon, Alba; Montenegro, Luis; Cuevas, Jaime; Turrero, María J.; Naves, Acacia; Fernández, Raúl; Torres, Elena (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 ... -
Dynamic update of flow and transport parameters in reactive transport simulations of radioactive waste repositories
Fernández Águila, Jesús; Samper, Javier; Mon, Alba; Montenegro, Luis (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 ... -
Hydrogeology and Groundwater Management in a Coastal Granitic Area With Steep Slopes in Galicia (Spain)
Naves, Acacia; Samper, Javier; Pisani, Bruno; Mon, Alba; Dafonte, Jorge; Montenegro, Luis; García-Tomillo, Aitor (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 ... -
Long-term non-isothermal reactive transport model of compacted bentonite, concrete and corrosion products in a HLW repository in clay
Mon, Alba; Samper, Javier; Montenegro, Luis; Naves, Acacia; Fernández Ruiz, Jesús (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 ... -
Modelling of the long-term evolution and performance of engineered barrier system
Claret, Francis; Dauzeres, Alexandre; Jacques, Diederik; Sellin, Patrik; Cochepin, Benoit; De Windt, Laurent; Garibay-Rodríguez, Jaime; Govaerts, Joan; Leupin, Olivier; Mon, Alba; Montenegro, Luis; Montoya, Vanessa; Prasianakis, Nikolaos; Samper, Javier; Talandier, Jean (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 ... -
Reactive transport modelling of a low-pH concrete / clay interface
Idiart, Andrés; Laviña, Marcelo; Kosakowski, Georg; Cochepin, Benoit; Meeussen, Johannes C.L.; Samper, Javier; Mon, Alba; Montoya, Vanessa; Munier, Isabelle; Poonoosamy, Jenna; Montenegro, Luis; Deissmann, Guido; Rohmen, Stephan; Damiani, Leonardo Hax; Coene, Emilie; Naves, Acacia (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 ... -
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
Samper, Javier; Naves, Acacia; Montenegro, Luis; Mon, Alba (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
Montenegro, Luis; Samper, Javier; Mon, Alba; De Windt, Laurent; Torres, Elena; Cuevas, Jaime; Fernández, Raúl; Turrero, Maria J. (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. ...
