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 single-site reactive transport model of Cs+ for the in situ diffusion and retention (DR) experiment
Yi, Shuping; Samper, Javier; Naves, Acacia; Soler, Josep M. (Springer, 2015)[Abstract:] In situ diffusion experiments are performed in underground research laboratories for understanding and quantifying radionuclide diffusion from underground radioactive waste repositories. The in situ diffusion ... -
Conceptual and numerical models of solute diffusion around a HLW repository in clay
Samper, Javier; Naves, Acacia; Lu, Chuanhe; Li, Yanmei; Fritz, Bertrand; Clément, Alain (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 ... -
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 ... -
Digitalisation for nuclear waste management: predisposal and disposal
Kolditz, Olaf; Jacques, Diederik; Claret, Francis; Bertrand, Johan; Churakov, Sergey V.; Debayle, Christophe; Diaconu, Daniela; Fuzik, Kateryna; García-Cobos, D.; Graebling, Nico; Grambow, Bernd; Holt, Erika; Idiart, Andrés; Leira, Petter; Montoya, Vanessa; Niederleithinger, Ernst; Olin, Markus; Pfingsten, Wilfried; Prasianakis, Nikolaos; Rink, Karsten; Samper, Javier; Szöke, István; Szöke, Réka; Theodon, Louise; Wendling, Jacques (Springer, 2023)[Abstract:] Data science (digitalisation and artificial intelligence) became more than an important facilitator for many domains in fundamental and applied sciences as well as industry and is disrupting the way of research ... -
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 ... -
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 ... -
