Digital Twins for Nuclear Containment Vessel Integrity

This presentation focuses on the development and application of digital twins carried to study the long-term behavior and leakage tightness of double-wall containment vessels in nuclear power plants. By combining advanced simulations with real-world data, digital twins offer an advanced approach to understanding and managing critical physical phenomena in aging infrastructure.Digital twins act as virtual replicas of physical systems, allowing for the simulation, monitoring, and prediction of structural performance. For nuclear containment vessels, this approach is particularly valuable in:• Understanding Physical Phenomena: Capturing the complex interactions between gas flow, material degradation, and environmental effects.• Anticipating the future repair works in order to improve or maintain leakage tightness of the existing vessels and evaluate the effectiveness of these works,• Carrying out safety studies to evaluate their safety margins.
