In early 2015, the National Cooperative for the Disposal of Radioactive Waste, Nagra, proposed two locations for storage in deep geological repositories. The “Expert Group on Geological Repositories” (EGGR) is now presenting its assessment of this restriction on further investigations, and is calling for a third location north of Lägern, as already proposed by the Swiss Federal Nuclear Safety Inspectorate ENSI to be given further consideration. Two Eawag scientists with a seat in the Expert Group were Dr. Annette Johnson (†2015) and Prof Rolf Kipfer – both of whom are specialists in rock-water interaction.
