Advanced Nuclear Technologies (AMR/SMR)


The international community is committed to developing low-carbon energy for use across sectors such as electricity, heating, transportation, and industry. However, existing energy sources that emit low CO2 levels are not yet sufficient to achieve carbon neutrality, representing only 13% of the global energy mix.

Against the backdrop of the energy transition and increasing electricity demand worldwide, ANTs (Advanced Nuclear Technologies), including AMRs (Advanced Modular Reactors) and SMRs (Advanced Modular Reactors) provide a concrete solution:

  • to replace fossil fuel plants which emit high levels of CO2 and are still over-used,
  • to compensate difficult access to low-carbon electricity in remote locations and off-grid facilities,
  • to address the need for low-carbon energy production as close as possible to where it is needed (e.g., by replacing generators),
  • to offset intermittent renewable energies,
  • to promote nuclear as a source of electricity and heating, including hydrogen production
  • to overcome the difficulties and constraints associated with large-scale nuclear projects (particularly financing),
  • to help countries around the world achieve energy independence.

The development of a global ANT market is a cornerstone challenge for governments and operators seeking to develop and sell this new type of modular reactor.


In order to offer more flexibility to the nuclear industry, Assystem has developed engineering, project management and digital services to promote the technological and commercial development of AMR and SMR projects in France and worldwide.

Our teams are already involved in a number of major AMR/SMR programmes, on behalf of both start-ups and nuclear operators : ROLLS ROYCE (SMR), NAAREA (XAMR), EDF NUWARD (SMR), NEWCLEO (AMR),  JIMMY (AMR)...

We support technology providers, end users, and vendors as well as safety authorities and governments in their AMR/SMR projects (reactors and cycles).
