Nuclear energy has a vital role to play in the global energy transition. For this reason, it’s the subject of constant research and innovation to improve production methods, performance, and safety and security processes.

Around the world, there are numerous research facilities with diverse interests: experimental reactors, research laboratories, and research support facilities (storage of materials and waste, effluent treatment plants, etc.) operated throughout the world.

For all these types of facilities, the challenges in terms of design, civil engineering, safety, physical and cybersecurity and even complex project management in highly regulated environments are top priorities for operators. Added to this are requests for expertise in research and development (each facility is unique), as well as modularity and scalability.


Tackling the scientific and technological challenges of research facilities by delivering reliable and safe infrastructure is the commitment we make to our customers. Leveraging our expertise in all types of nuclear facilities, we support nuclear research to guarantee:

  • Facility designs are adapted to the specific issues addressed in the relevant research centre, both in terms of buildings and processes
  • Reliable construction, in compliance with the requirements of facility activities
  • Management of nuclear risks and guaranteed best-in-class safety conditions, from design through to decommissioning
  • Full-scale planning and control of potential threats or attacks on security and industrial cybersecurity in line with the sensitive nature of on-site activities


For decades, Assystem has acted as a trusted partner for research centres, supporting their development and the daily operations of their facilities. Our teams support many research projects spearheaded by the CEA, the French Alternative Energies & Atomic Energy Commission, as well as major international research projects in fusion power (ITER in France, STEP in the UK, etc.).
