In the 1990s the Swiss Federal Nuclear Safety Inspectorate (HSK) identified the need to update the seismic hazard assessments for Swiss NPPs and in 1998 asked the Swiss NPP operators to draw up a new hazard study that would comply with SSHAC level 4 (SSHAC, 1997) requirements. Nagra (the National Co-operative for the Disposal of Radioactive Wastes) was commissioned to plan, organize and perform such a study – the PEGASOS project (Probabilistische Erdbeben-Gefährdungs-Analyse für KKW-Standorte in der Schweiz). The project involved more than 20 experts from seven European countries, with support provided by 25 Swiss and foreign specialists and consultants. The project was completed in the summer of 2004. In 2008 the "PEGASOS Refinement Project" was launched in order to address potential refinements. As part of this project the SED was commissioned to provide input and to develop specific products:
