Seismic protection and vibration control for Nuclear Containments

Structural response control for safety, operability and long-term integrity

Nuclear containment structures must remain functional and structurally sound under seismic events and operational vibrations. Earthquakes, dynamic equipment loads and external excitations can induce forces that exceed conventional design limits. Seismic protection and vibration control systems reduce transmitted forces, limit structural response and protect critical components. VSL provides engineered solutions adapted to nuclear safety, performance and regulatory requirements. 

Why seismic protection and vibration control for nuclear containments 

Nuclear facilities are designed to withstand severe seismic actions while ensuring continued safety and containment integrity. Uncontrolled vibrations and seismic forces can cause excessive stresses, damage equipment or compromise structural elements. Seismic protection and vibration control systems modify the dynamic response of structures, dissipate energy and reduce demand on critical components, ensuring predictable and compliant behavior during seismic events.

Energy dissipation limits forces transmitted to structures and equipment.

Systems reduce accelerations, displacements and internal stresses.

Sensitive equipment and interfaces remain operational after seismic events.

Solutions are designed for site-specific seismic and dynamic conditions.

Design and execution meet strict safety, quality and traceability standards.
