Project Details
Description
FN-CAMP is a research project that focuses on supporting ageing related aspects for both Finnish NPP concrete infrastructure and Finnish radioactive waste repository concrete structures. The FN-CAMP project aims at having a significant impact on the safety of operational Gen II and Gen III NPPs and impact the long-term performance of concrete repository structures. FN-CAMP will improve the understanding of ageing/deterioration of concrete and will provide tools and guidance to the assessment of safety margins for structural performance. The outcomes from FN-CAMP will therefore support the ageing management of NPPs and concrete repository structures and help prepare NPPs for LTO.
The selected ageing mechanisms studied in FN-CAMP correspond to research areas of recognized knowledge gaps of high importance to Finnish NPPs and RWSs. The concrete ageing mechanism addressed are alkali-silica reaction, aggressive aqueous attack, embedded liner corrosion and spent fuel pool liner corrosion, containment monitoring data analysis. The FN-CAMP project will have impact through:
• Identification of key relevant knowledge gaps for ageing processes of reinforced concrete SSCs in the frame-work of transition from ageing management (AM) to LTO of relevance for Finnish NPPs and RWSs.
• Development of an assessment tool for ASR expansion in concrete will contribute to predicting the behaviour of concrete under various exposure conditions (e.g., relative humidity, temperatures, and confining stresses), and thus improve our understanding of the mechanism of ASR expansion.
• Development of an assessment tool to predict the deterioration of concrete exposed to an aggressive aqueous environment will contribute to evaluating the deterioration degree of concrete and comparing the deterioration rate at given exposure durations.
• Increased understanding of the corrosion mechanism enables greater precision in term of location of corrosion locations, reducing the costs of inspections.
• Results will contribute to improved modelling capabilities which will enable better maintenance and ageing management practices of containment and pool liners.
• Increased understanding of the structural behaviour of the pre-stressed containment building during short-term events, such as pressure tests, and long-term behaviour, such as leak-tightness in aged concrete structures.
• Contribution to development of an overall strategy within the EU for the safe life long-term prediction of reinforced concrete SSC’s for NPPS and RWSs.
• Dissemination of best practice guidelines for performance assessment related to key ageing and deterioration mechanism and lifetime management of reinforced concrete.
• Contribution to improvements in cost-effectiveness and safety of both existing and future NPPs and RWSs.
FN-CAMP also embraces the competence development of young research scientist and their specialization related to the “nuclear” concrete domain. Furthermore, FN-CAMP focuses on the dissemination and the education of the nuclear engineering and research community. This will contribute to harmonize knowledge about nuclear concrete ageing. The education will be carried out through workshops and trainings organized during the project. FN-CAMP results will be disseminated to the Finnish and international stakeholders through participation in targeted dissemination activities.
