| 20120124920 | Smart isolation base for sensitive structures such as Nuclear power plants against earthquake disturbances - An isolation base system for sensitive structures such as nuclear power plant modules is suggested. The proposed isolation system considers a base supported on specially designed hollow spherical balls and equipped with 3 linear hydraulic actuators to restrict the lateral motion of the base and provide a stable base under normal conditions. The actuators are released when an earthquake signal is detected to allow the base to oscillate freely during the earthquake attack. The hydraulic actuators are reactivated after shock wave ends to compress the springs and restore the base to its original position. | 05-24-2012 |
