Stage 2

(Video in German only)

The National Cooperative for the Disposal of Radioactive Waste (Nagra) had the task of proposing at least two siting regions per repository type (low and intermediate level waste on the one hand, high level waste on the other) in stage 2, which are to be investigated further in stage 3. It proposed the two areas Jura Ost and Zürich Nordost, where both types of waste can be stored. The Swiss Federal Nuclear Safety Inspectorate (ENSI) reviewed the proposal and found that the data basis for deferring the Nördlich Lägern siting area was not good enough. The Federal Nuclear Safety Commission (NSC) was of the same opinion. The Federal Council therefore decided at the end of 2018 that all three siting regions should be investigated further in stage 3. In addition to narrowing down the possible sites , sites for the surface facilities were identified and designated in stage 2 in close cooperation with the siting regions. An impact study was also carried out to determine the possible socio-economic and ecological effects of a deep geological repository on the siting regions.

This map shows the result of stage 2. The three siting regions Jura-Südfuss (SO/AG), Südranden (SH) and Wellenberg (NW), hatched in yellow, were included in the sectoral plan as reserve options. In July 2024, DETEC removed these three reserve options from the sectoral plan as they have clear disadvantages compared to the siting regions Jura Ost (AG), Nördlich Lägern (AG/ZH) and Zürich Nordost (TG/ZH).
