Abstract The principal objective of NF-PRO is to establish the scientific and technical basis for evaluating the safety function "containment and minimisation of release" of the near-field of a geological repository for high-level radioactive waste and spent fuel. To this end, NF-PRO will investigate dominant processes and process couplings affecting the isolation of nuclear waste within the near-field and apply and develop conceptual and mathematical models for predicting the source-term release of radionuclides from the near-field to the farfield. Results and conclusions of experimental and modelling work will be integrated in performance assessment. To understand the performance of the overall near-field system, an adequate insight in both the performance of the individual near-field sub-systems and their interactions is essential. Accordingly, the Integrated Project NF-PRO has been structured in five Research and Technology Development Components (further referred to as RTD Components) each representing a major near-field sub-system. In particular, RTD Components 1 to 4 address key processes controlling dissolution of and release from the waste matrix, chemical processes taking place in the Engineered Barrier System (EBS), the thermo-hydromechanical (THM) evolution of the EBS and the characteristics and the evolution of the excavation disturbed zone (EDZ), respectively. Process couplings and integration in performance assessment (PA) are dealt with in RTD Component 5. This RTD component will play a pivotal role in IP NF-PRO. At the initial phase of NF-PRO, RTD Component 5 will provide a realistic description of the evolution of the conditions in the near-field in view of identifying key processes and remaining uncertainties to be addressed by RTD Components 1 to 4. Throughout the project, RTD Component 5 will analyse macroscopic mass and energy flows and integrate the outcome of RTD Components 1 to 4 in PA through 'Integration Excercises'. These exercises will be performed for the main potential host rocks currently investigated for HLW disposal in the EU: clay, granite and salt. In addition to the scientific-technical objectives, the consortium will make the acquired data, knowledge and expertise available and accessible to the broad scientific community within the EU and NAS, use its expertise for public information purposes and promote knowledge and technology transfer through training. Component 6 brings together all activities concerning training (including knowledge management and transfer).
