      Article
      Accés obert
      This work presents experimental data and modelling of the release of Mo from high-burnup spent nuclear fuel (63 MWd/kgU) at two different pH values, 8.4 and 13.2 in air. The release of Mo from SF to the solution is around ...

    • Modelling the release of Mo, Tc, Ru and Rh from high burnup spent nuclear fuel at alkaline and hyperalkaline pH 

      Giménez Izquierdo, Francisco Javier; Pablo Ribas, Joan de; García Gómez, Sonia; Serrano Purroy, Daniel; Iglesias Pérez, Luis; Clarens Blanco, Frederic; Martínez Torrents, Albert (Cambridge University Press, 2023-12-30)
      Article
      Accés obert
      The present work shows experimental data on the release of some radionuclides that are forming the so-called e particles in the spent nuclear fuel (SNF): Mo, Tc, Ru and Rh. The leaching experiments were carried out with a ...

    • Bioderived pickering emulsion based on chitosan/trialkyl phosphine oxides applied to selective recovery of rare Earth elements
