    6. INE 2011 The EPR™ Resistance to Extreme Hazards – September 29th, 2011 p.6 The EPR is licensed to resist to a 0.25g-0.3g peak ground acceleration Seismic Margin Assessments performed for safety authorities in the UK and US show that even a 0.6g peak ground acceleration earthquake would not have significantly impacted the EPR capabilities to mitigate the risk of severe accident No cliff-edge effect illustration: Earthquake beyond worst case scenario
