- CLEARSY designs and realizes its own systems, hard-wired or programmed, and assists the main Energy manufacturers: EDF, CEA, Areva TA, Alstom Power, Siemens, Schneider Electric, General Electric, Vinci Energie, Spie Nucléaire, Clemessy, Comex Nucléaire, Eiffage, DCNS. CLEARSY is a referent for many post-Fukushima refurbishing projects.
- The tools, advanced methods, and safety critical design experience feedback of CLEARSY, are used to assume command control projects requirements or design of components, with hardware and software features, consideration of normative standards, mastering of the life cycle, and compliance with nuclear authorities requirements.
- A continuous technological surveillance is carried out to perform systems and projects compliance to standards IEC 61508 and derivatives (IEC 61511…), to nuclear corpus SC45A (IEC 61513, 61226, 60880, 62138…) and to RCC- E.
