Abstract
The near-field of a geological repository for the disposal of high-level radioactive waste and spent nuclear fuel plays a key role in ensuring the long-term safety of disposal: the principal function of the near-field is to contain radionuclides and to minimise/retard their release from the waste to the host rock. However, the near-field represents a complex environment consisting of various engineered barriers and repository components including the waste form, the waste canisters, backfills, seals, plugs and the disturbed zone of the host rock component. An in-depth understanding and quantification of the evolution of key processes, their couplings as well as their impact on transport from the waste packages to the near-field/geosphere boundary is fundamental to the assessment of the long-term safety of disposal. The paper gives an overview of the scope and the objectives of NF-PRO and discussed how results from detailed process investigations are applied in assesments of the overall near-field system performance.
