The obtained values represent the fault hazard along the principal fault; however, in the framework of the siting process, the CE-3 exclusion criterion excludes all those areas located less than 2.5 km from an active and capable fault. In this work we have started to explore this topic and we have presented the results for the annual frequency of exceedance on the principal fault. With the final aim to select the definitive site of the plant, our next goal is to i) investigate different seismotectonic settings in Italy and ii) perform a site- specific assessment by Probabilistic Fault Displacement Hazard Analysis on primary and on distributed faulting.
