SERB Devices for the Isolation of Buildings and Equipment Against Shocks, Vibrations and Seismic Movements Available to Purchase

The paper presents new types of devices to isolate buildings and equipment against shocks, vibrations and seismic movements, developed by SITON in cooperation with other units in Romania. The new devices, called SERB devices, can overtake very large static loads (over 3000KN) over which dynamic loads are overlapping and damped. The devices allow the “cutting-off” of the dynamic action coming from the environment to the isolated component (building or equipment) and the shocks and vibrations generated by the component to the environment. The relative displacements allowed by the devices in horizontal plane, reach up to ±200mm and their capacity to dissipate the energy is very high. The devices can overtake compression and tension loads up to half of the maximum compression load. The devices are made of materials that practically, are not affected by the aging phenomenon and they may be guaranteed for the entire service-life of a nuclear power plant, without maintenance and repair. The sizes of the devices are small if compared with the sizes of the existing devices and the performances are similar. The radiation resistance capacity is very good allowing thus their use in all the areas of a nuclear-power plant.
