Certifications and qualifications


Sofren's commitment to quality and safety management is proven in every area of operation: ISO 9001 certification since 2009, OHSAS 18001 since 2016, and previously MASE, from 2013 to 2016.

Sofren has also been CEFRI-E certified since 2010 and therefore implemented a radioprotection management system.

In many more specific areas our expertise and the reliability of our methods and organization can be seen in the qualifications and approvals we have obtained from the major players in our sectors of activity.

Sofren has been CEFRI-E certified since 2010 (Comité Français de certification des Entreprises travaillant sous Rayonnements Ionisants - French certification committee for working with ionizing radiation). This certification allows Sofren to carry out activities involving ionizing radiation in basic nuclear installations (INB - Installations Nucléaires de Base) and secret basic nuclear installations (INBS - Installations Nucléaires de Base Secrète). The company therefore established a radiation protection management system.
