VeRCoRs Experience: Predicting Containment Ageing, From the Mockup to the Digital Twin

This session will present the largest panel of the VeRCoRs project and share the best outcomes that have been raised up to now through this project for long term operation purpose involving ageing effect modeling.

This session will include the VeRCoRs mockup and the overall project: mockup description, accelerated ageing effects, monitoring system, accompanying research program. The main described topics are how it helps to improve ageing effect characterization, the leak rate prediction and its modeling and the latest progress in the field of digital twin of civil structures at the service of ageing prediction effect and long term operation.
