The Wellenberg is a 1341 meter high mountain, mainly in the canton of Nidwalden and a smaller part in the canton of Obwalden in Switzerland. It became known nationally because of the intentions that have existed since 1987 to build a repository for radioactive waste there.
geography
The Wellenberg is mainly located in the municipality of Wolfenschiessen ; next to a smaller part of Engelberg .
geology
The main rocks of the wave mountain are two marl formations and silica limestone . There is also some Malm and Schrattenkalk .
Repository project
In 1987 Nagra announced its intention to build a deep repository for low- and intermediate-level radioactive waste in the Wellenberg. To do this, she wanted to examine the interior of the mountain with, among other things, exploratory boreholes . The two marl formations were seen as host rock for storage.
Right from the start, the regional population resisted such a project. In 1995 and 2002, cantonal referendums were held in Nidwalden that rejected the camp. Although they were not legally binding for the federal level , they exerted political pressure. The storage project was scientifically pursued, but without the intended extended exploratory tunnel.
In January 2015, Nagra made a preliminary decision that postponed the wave mountain due to less favorable rock formations compared to other locations in the Zurich wine region and the Bözberg region .
