Seismic Vibration Testing Lab - US Technical Center
AREVA's seismic analysis laboratory is built around a 10' x 10' electro-hydraulic multi-axial 7-ton shake table capable of testing items weighing up to 10 tons at a maximum of 100 Hz with peak acceleration from 5- to 20-g, dependent on the item's mass.
Customers may view the seismic tests from an elevated observation area.
AREVA's Seismic/Vibration Lab can play a key role helping utilities assess nuclear components to address industry regulations and guidelines.
