Iris pit

The 15 m deep Iris testing pit with a 4.2x4.2 m hexagonal section makes possible the testing of large height filiform equipments such as nuclear reactor control rods. Actuators fixed to the pit partitions allow the structure to be requested radially. For the vertical excitement, an actuator is placed under the structure.
