What CERAP GROUP does

CERAP GROUP is a French private nuclear industry services company, founded in 1986 and operating as a subsidiary of the diversified ALTRAD Group. It delivers radiation protection, nuclear safety, HSE prevention, radiological metrology, engineering, and training services through seven specialized entities: CERAP Prévention, ADVANCE Engineering, ATRON Metrology, NUSAM (UAE), CERAP Switzerland, CERAP UK & Nordics, and SEFC Formation. Its primary customers are nuclear power operators, fuel cycle companies, and research institutions including EDF, CEA, CERN, Orano, Westinghouse, and ENEC, with framework contracts spanning 15 years (EPR2 Gravelines) and pluriannual terms (CEA Cadarache ventilation, EDF national PIAT). Geographically it operates across France, the United Kingdom, Switzerland, and the United Arab Emirates.

CERAP GROUP's core technology stack centers on the FELIX electrostatic electron accelerator (200 keV to 3.5 MeV, dose rates up to 500 Gy/h) operated by ATRON Metrology, which underpins a COFRAC-accredited (ISO/IEC 17025) and ASNR-authorized calibration and irradiation testing laboratory. Proprietary product-level assets include the ARREX autonomous surface contamination detection robot (third place, EDF DPNT Innovation Challenge 2025) and a virtual reality training platform piloted at CNPE Penly. The group invests in a formalized scientific direction (Direction Scientifique et Technique, created 2025) and an AI roadmap, and participates in the Normandie Accélérateurs ecosystem alongside GANIL, CEA, CNRS, and CNES for radiation testing in space, defense, and nuclear sectors.

CERAP GROUP generates revenue through four primary streams: technical assistance and engineering services (framework contracts with EDF and other operators), radiological measurement and analysis (accredited calibration and project-based testing), regulatory training (PCR certification, HSE training for CERN and industrial clients), and delegated operations management (e.g., the environmental chemistry laboratory at CEA Cadarache). Pricing is not publicly disclosed; revenue is won through competitive tenders and long-term framework agreements. The 15-year EPR2 Gravelines co-contractor role with Bureau Veritas, 19 active job openings, and a new SEFC Formation training center in Dieppe (January 2026) signal ongoing capacity build-out aligned with the French nuclear new-build cycle.

Scale indicators8 records

Recent moves8 records

Expansion highlights7 records

Direct peers

• Bureau Veritas: Global TIC (testing, inspection, certification) major that co-contracts with CERAP Prévention on the EPR2 Gravelines program. Both firms compete and collaborate on HSE coordination, industrial inspection, and nuclear safety services for EDF and other operators.
• Assystem: French-headquartered nuclear engineering and digital services firm providing technical assistance, project management, and engineering services across the nuclear lifecycle. Directly comparable as an EDF framework contractor with similar tier-one service portfolio.
• ONET Technologies: Division of ONET Group specializing in nuclear services including radiation protection, decontamination, and decommissioning. Direct competitor in French nuclear services with comparable scope across radiation protection and facility operations.
• Nuvia: European nuclear services firm (Vinci subsidiary) offering radiation protection, health physics consultancy, decommissioning, and waste management. Closely comparable in service portfolio and customer base across UK and French nuclear markets.
• Sogema: French specialist in radiation protection and radiological survey services, serving CEA and EDF sites. Closely comparable niche peer operating in the same French nuclear services market as CERAP Prévention.

Broad incumbents

• Framatome: EDF-controlled nuclear reactor OEM and services giant with extensive service portfolio covering fuel, components, and instrumentation. Although a customer of CERAP in some contexts, Framatome also offers overlapping radiation protection and I&C services at much larger scale.
• Veolia Nuclear Solutions (now Orano Projets): Provides nuclear facility clean-up, decontamination, and decommissioning services within the Orano group. Comparable in radiological services scope, with broader decommissioning and waste-management capabilities than CERAP.
• Jacobs Critical Mission Solutions: Major U.S.-headquartered engineering consultancy with a dedicated nuclear and critical mission practice serving government and commercial nuclear clients globally. Comparable as a multi-disciplinary nuclear services partner, though much larger and broader in scope.

Emerging players

• Mirion Technologies: Global leader in radiation detection, measurement, and monitoring instrumentation. Overlaps with CERAP's ATRON Metrology capabilities in calibration, dosimetry, and radiation monitoring products, though Mirion is more product-focused versus CERAP's services focus.

Others

• Altrad Group (Parent): CERAP's parent company providing industrial services including scaffolding, insulation, and mechanical services across multiple end-markets. Related through ownership and One ALTRAD cross-selling synergies (e.g., One ALTRAD Suisse shared office), but not a direct peer in nuclear services.
