The effect of the evolution of environmental conditions on the corrosion evolutionary path in a repository for spent fuel and high-level waste in Opalinus Clay

The corrosion evolutionary path (CEP) defines the time-dependent corrosion behaviour of canisters in a deep geologic repository. In turn, the CEP is largely determined by the evolution of the environmental conditions in the near- and far-fields. The evolution of environmental conditions in a repository for spent fuel and high-level waste in Opalinus Clay is described along with the impact on the corrosion behaviour of the canisters.
