      Rodríguez Dono, Alfonso; Olivella Pastallé, Sebastià; Mokni, Nadia (2020-02)
      Article
      Restricted access - publisher's policy
      This paper assesses a model for the full-scale engineered barrier experiment (Febex) in situ test, simulating the disposal of heat-emitting, high-level spent nuclear fuel. The model has been developed using Code_Bright and ...
    • Chemo-hydro-mechanical behaviour of compacted Boom Clay: joint effects of osmotic and matric suctions 

      Mokni, Nadia; Romero Morales, Enrique Edgar; Olivella Pastallé, Sebastià (Thomas Telford, 2014-07)
      Article
      Restricted access - publisher's policy
      An experimental programme involving osmotic and matric suction controlled tests is carried out to investigate the effects of increasing pore fluid concentration, chemical cycling (salinisation/dilution) and matric suction ...
    • Deformation and flow driven by osmotic processes in porous materials 

      Mokni, Nadia (Universitat Politècnica de Catalunya, 2011-02-22)
      Doctoral thesis
      Open Access
      En el caso del almacenamiento de los residuos radioactivos los flujos osmóticos pueden ser relevantes y requieren un análisis en detalle. El residuo nuclear bituminizado (BW) será almacenado mediante contenedores en cavidades ...
    • Hydro-chemical modelling of in situ behaviour of bituminized radioactive waste in Boom Clay 

      Mokni, Nadia; Olivella Pastallé, Sebastià; Valcke, Elie; Bleyen, N; Smets, Esteven; Li, Xiang Ling; Sillen, X. (2014-06)
      Article
      Open Access
      The hydro-chemical (CH) interaction between swelling Eurobitum bituminized radioactive waste (BW) and Boom Clay was investigated to assess the feasibility of geological disposal for the long-term management of this waste. ...
    • Microstructural and hydro-mechanical behaviour of bentonite pellets and powder mixtures 

      Mesa Alcantara, Arisleidy; Romero Morales, Enrique Edgar; Mokni, Nadia; Olivella Pastallé, Sebastià (EDP Sciences, 2020-10)
      Article
      Open Access
      Binary mixtures of high-density MX-80 bentonite pellets (80%) and bentonite powder (20%) at hygroscopic water content have been recently considered as an alternative engineered barrier system for the long-term disposal of ...
    • Modelling of oedometer tests on pellet-powder bentonite mixtures to support mock-up test analysis 

      Mesa Alcantara, Arisleidy; Mokni, Nadia; Romero Morales, Enrique Edgar; Olivella Pastallé, Sebastià (EDP Sciences, 2020-10)
      Article
      Open Access
      Bentonite mixtures of MX-80 (80% of high-density pellets and 20% of bentonite powder on a mass basis) have been recently proposed as a candidate material for sealing deep geological disposals of high-level radioactive ...
    • Water retention properties and microstructure of bentonite pellets/powder mixture 

      Molinero Guerra, Agustín; Mokni, Nadia; Cui, Yu-Jun; Minh Tang, Anh; Aimedieu, Patrick; Delage, Pierre; Bernier, Frédéric; Bornert, Michel (Universitat Politècnica de Catalunya. Departament d'Enginyeria del Terreny, Cartogràfica i Geofísica, 2015-06-02)
