TechnicAtome is a defense and space manufacturing firm based in Villiers-le-Bâcle, Île-de-France, with more than five decades of experience in compact nuclear reactor technology. The company designs, builds, commissions, and maintains compact reactors, covering the full lifecycle from concept to ongoing operational support. Its engineering work supports naval propulsion, research, medical nuclear applications, and energy projects. TechnicAtome participates in three major nuclear propulsion programs at different stages—the Suffren-class submarine program, the SNLE 3G program, and the Nouvelle Génération aircraft carrier program. It also pursues civil nuclear initiatives, such as the Jules Horowitz experimental reactor and development work on small modular reactors. In 2023, Naval Group broadened its collaboration with TechnicAtome to cover production and manufacturing of the main components of the nuclear boilers for the Barracuda program.
