Although nuclear power plants are some of the most earthquake-resistant buildings in Switzerland, earthquakes are a major part of the risk of nuclear power plants. “This is precisely why we are so keen to ensure that nuclear plant operators regularly update their comprehensive seismic safety cases and that these then comply with the latest scientific evidence – especially if this evidence suggests that stricter requirements are now necessary,” explains Hans Wanner, director general of ENSI. This comply with a legal provision and is safety oriented.
