Nuclear propulsion
DCNS manufactures the main primary circuit capacities for naval pressurized water propulsion reactors fitted in the French Navy's nuclear-powered vessels.
Through its production activities, DCNS has developed exceptional expertise in the design and manufacture of pressurized equipment, exchangers and nuclear boiler work.
This equipment complies with French and international RCC-M and ASME construction standards for the nuclear components and the CODAP code for pressurized equipment.
