TechnicAtome Tech Stack

Compact nuclear reactor design and lifecycle management for naval propulsion and civil research

Defense and Space Manufacturing Villiers-le-Bâcle 1,001–5,000 employees Founded 1972 Self-Owned

TechnicAtome designs and operates compact nuclear reactors across military and civilian programs, with over 50 years of specialization in propulsion systems. The company is scaling engineering capacity (78 active roles) while investing in IT infrastructure modernization—notably an IT urbanization plan and PowerShell automation for compliance controls—suggesting an effort to bridge legacy CAD/PLM tooling (CATIA, 3DEXPERIENCE, Maximo) with contemporary DevOps practices. Adopting S1000D (technical documentation standard) while replacing CATIA indicates a shift toward standardized, lifecycle-aware engineering workflows.

About TechnicAtome

TechnicAtome develops compact nuclear reactors for naval propulsion, research facilities, and small modular reactor (SMR) programs. The company operates across three major military propulsion programs—Suffren-class submarine reactors, third-generation SSBN reactors, and next-generation carrier propulsion—while contributing to civil projects including the Jules Horowitz experimental reactor and SMR technology development. Headquartered in Villiers-le-Bâcle with operations across eight French sites, the company employs over 2,200 staff, with approximately 90% concentrated in the southeast. Engineering-led workflows rely on PLM (3DEXPERIENCE), CAD (CATIA), and legacy enterprise systems (SAP, Maximo, Primavera P6), supported by quality-assurance methodologies (FMEA) and security infrastructure (PKI, Active Directory).
