Seismic Vibration Testing Lab - US Technical Center

AREVA seismic shake table

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.
