Greek nuclear startup Athlos Energy has completed what it said is the first preliminary siting study for nuclear power plants finding that the country’s high seismicity could sharply limit options for large reactors, while smaller reactors could open a wider range of potential locations.

Athlos said the study used US-based Cambrian Nuclear’s Plinth platform, a site-assessment tool for nuclear power plants that allows combined analysis of geospatial, seismotectonic and geomorphological data.
