      abstract     = {Systematic single-effect dissolution studies were carried
                      out on the dissolution behaviour of pure and Cr- or Nd-doped
                      UO2 reference pellets as model materials for spent nuclear
                      fuel with varying doping levels, densities, and grain sizes
                      as well as of industrially produced Cr- and Cr/Nd-doped UO2
                      pellets. The results were obtained from accelerated static
                      batch dissolution experiments performed under strictly
                      controlled conditions using H2O2 as simulant for radiolytic
                      oxidants formed due to the alpha-irradiation of water. The
                      results indicate that the addition of Cr and the
                      consequential modification of the fuel matrix does not lead
                      to a significant change of the dissolution behaviour of
                      these model materials compared to pure UO2 reference
                      materials. Contrarily, the dissolution rates of Nd-doped
                      pellets are significantly lower than those of pure and
                      Cr-doped pellets. These results provide additional insights
                      into the influence of doping on the dissolution behaviour of
                      modern spent light water reactor fuels under the
                      post-closure conditions expected in a deep geological
                      repository.},
