Our projects

Nuclear propulsion & Defence

TechnicAtome combines its experience as a designer of naval propulsion nuclear reactors and an operator of nuclear defence facilities.

TechnicAtome is currently carrying out 3 major nuclear naval propulsion programs. Over a 20-year period, Technicatome will deliver 11 nuclear steam supply systems for the Barracuda program (nuclear attack submarines), the SNLE 3G rocket-launching nuclear submarines and the new generation aircraft carrier. Processed simultaneously, they are at different progress stages.

20 years of design and 40 years of operation, it’s the time of nuclear naval propulsion projects led by TechnicAtome.
