The Gösgen Nuclear Power Plant in Switzerland provides a good example of long-term use of elastic support and damping systems for various key components in nuclear power generating plants. During the operation of machines such as turbines, pumps and other rotating equipment, disturbing vibrations can affect other parts in the nuclear power plant. Vibration isolation technologies suppress these disturbing effects and can be installed as elastic support systems. These technologies can also be integrated for special protection of the installed safety systems to protect from external loads such as earthquakes, aircraft impact scenarios or the risk of possible foundation settlements. Together with the team in Gösgen, we took a look at the elastic support systems that have been installed over the past decades and representatives of the operator gave some statements about their corresponding experience.
