Structural Mechanics Group
The Structural Mechanics Group evaluates the structural integrity of safety-related components and systems in nuclear power plants. The primary focus is the independent verification of complex analyses with regard to code-compliant design and the demonstration of structural integrity under normal operating, faulted and transient conditions. Through the combination of expertise in structural mechanics, advanced numerical methods, and a strong understanding of applicable codes and regulatory requirements, the group makes a significant contribution to ensuring structural integrity and compliance with nuclear safety requirements.
