Seismic Isolation Solutions for Nuclear Facilities

Nuclear power plants are high-risk facilities requiring protection against seismic hazards. SOCITEC designs decoupling systems based on the use of wire rope isolators and/or springs. Their features, including flexibility, damping capacity, deformation, and vibration dissipation, ensure effectiveness under extreme conditions. Our products offer long service life and withstand significant temperature and humidity variations as well as exposure to chemical agents.

Seismic protection in nuclear facilities goes beyond structural survival: every safety-critical system must remain fully functional during and after the event, because the post-earthquake cooling and shutdown sequences are as safety-critical as the earthquake resistance itself. Wire rope isolators and spring-based decoupling systems are particularly well suited to this context because they combine multi-axis flexibility, high damping capacity and long service life without maintenance, essential attributes in nuclear environments where access for inspection and replacement is restricted by radiation exposure constraints.
