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.},
