How we work


The safe disposal of our radioactive waste in a deep geological repository is a cross-generational project. We too have several generations dedicated to this mission: to Nagra, people make all the difference.

Quality management at Nagra

Nagra is certified in accordance with ISO 9001:2015 in all departments of the organisation. Recertification takes place every three years.

Quality Management (QM) is supported by an electronic system containing regularly updated versions of the relevant documents (process descriptions, guidelines, directives, templates, checklists, etc.), which are made electronically available to all Nagra employees. The QM system covers all Nagra activities in the head office in Wettingen, at the Grimsel Test Site and in the Mellingen drill core archive.
