A cutting-edge industrial tool

Nuclear safety culture

CNIM Systèmes Industriels has a strong nuclear safety culture, which has been reinforced over the years and through projects. Involved in international projects, our teams comply with the codes and standards of other countries.

For a long time, the nuclear safety culture has been integrated into our design, manufacturing, installation and maintenance activities through our quality management system, the deployment of a graded approach and the use of nuclear codes (RCCM / KTA / ASME...).

Since 2007 (start of a project for the Finnish EPR OL3 plant), a dedicated Nuclear Safety Culture Training is provided to all actors of nuclear projects, CNIM Systèmes Industriels' personnel and key subcontractors.

Since our first specific audit by NNB Gen Co / EDF Energie (February 2016), we have organised ourselves, structured ourselves and deployed a continuous improvement plan so that nuclear safety is and remains our priority.
