Seismic protection of equipment in a nuclear power plant
Since the Fukushima disaster, the seismic range considered in nuclear power plant design has become much more demanding. The big challenge was to come up with an alternative to the standard spring box for protecting nuclear power station equipment and ensuring that strategic equipment works effectively under extreme conditions.
At Socitec, we use dynamic application fields such as; compressed spring systems, swing, and rolling bridges for high-risk transportation of nuclear fuel and manufacturing nuclear containers in contaminated power plant zones.
Socitec has devised a decoupling system that uses wire rope isolators because of its high capabilities. This form of the spire-rolled cable has a lot of flexibility, damping capacity, significant deformation, and dissipation that is not affected by temperature, humidity, or any chemical agents and can therefore last as long as the equipment it protects.
As a result of years of researching and developing, Socitec has developed extensive expirte in the dynamic modeling of equipment. Socitec has used SYMOS software to model the equipment mounted on isolators, represented by elastic liaisons with properties of stiffness and non-linear isolation, to produce cable isolator suspension for a surge arrestor in seismic conditions.
