What Intercontrole does

Intercontrôle is a French Non-Destructive Testing (NDT) specialist founded in 1974 and operating as a wholly-owned subsidiary of Framatome within its Installed Base business unit. The company focuses on automated in-service inspection of primary-circuit components in pressurized water reactors — principally reactor pressure vessels and steam generator tubes — and conducts approximately 100 on-site interventions per year across nine countries (France, Belgium, Sweden, Switzerland, UK, Finland, Slovenia, South Africa, China). Its track record covers 350+ pressure vessels and 5 million+ steam generator tubes inspected worldwide.

The product portfolio is anchored by a set of proprietary, trademarked inspection platforms: the MIS in-service inspection manipulator (a 12-tonne, 12-meter robot with 1 mm positioning accuracy for reactor pressure vessels), the EXACT eddy-current inspection chain with real-time satellite data transmission, HELIOS oriented-illumination visual testing, LTcam laser thermography, Stitching video-analysis software, and Digital Radiography using a photon-counting detector. Supporting offerings include AIDA and other NDT software, custom eddy-current and ultrasonic probes, and automated/multi-axis robotic systems. R&D is conducted across 100 ongoing projects by 90 specialized engineers, with active programs in digital magnetic testing, ultrasonic imaging and time reversal, and AI for NDT (computer vision, anomaly detection, hybrid AI-physics models).

The business model combines professional-services revenue from recurring in-service inspection contracts with one-time equipment development/qualification, hardware sales of probes and robotic systems, and software licensing. The company sells direct to nuclear utilities and power-plant operators through enterprise field sales, supported by four French sites (Rungis HQ, Chalon-Sur-Saône engineering, Sully-sur-Loire and Cadarache hot shops), and is qualified to the major international nuclear codes (RSE-M, ASME, KTA, 10 CFR 50/21) and standards (ISO 9001, 14001, 45001, 19443, OHSAS 18001, CEFRI E). Average turnover is €99M with 382 employees including 155 COFREND Level 2/3-certified operators.

Products and services

• HELIOS (HEmispherical LIght Oriented Sensor) Visual testing technology using oriented illumination that reveals surface indications on materials and produces 3D data on indication morphology. Offered as turnkey product or as customer-specific development for nuclear and industrial inspection.
• LTcam Active infrared thermography NDT system using LASER thermal excitation to detect surface and sub-surface defects in materials. Provides an alternative to penetrant testing and magnetic particle testing methods.
• Stitching High-speed analysis technology for televisual inspection data that unfolds video acquisitions into a single large image without loss of sensitivity, enables sizing of indications, and reduces operator fatigue.
• Digital Radiography Innovative digital radiography solution using a photon-counting detector replacing conventional argentic film. Reduces exposure time by a factor of 10 and significantly shortens inspection duration for nuclear components.
• MIS (Machine d'Inspection en Service) 12-tonne robotic manipulator (12 metres height) for in-service inspection of nuclear reactor pressure vessels. Positions control tools with 1mm precision and is remotely controlled from outside the reactor building for operator safety.
• EXACT Inspection Chain Eddy current testing inspection chain for steam generator tube inspection in nuclear reactors. Command and data acquisition are performed remotely from a shelter outside the reactor building with real-time satellite transmission to Rungis for network analysis.
• NDT Software Suite (AIDA, Analysis, Supervision, On-board, Trajectory Management) Specialized NDT software suite including AIDA for eddy current data analysis, analysis software for coordinate system display, supervision systems for manual and automatic control of test machines, real-time on-board systems for acquisition processing, and complex trajectory management software for positioning probes on complex geometries.
• NDT Probes and Transducers (Eddy Current and Ultrasonic) Custom-designed eddy current probes (axial, rotating, blade) and ultrasonic transducers (single-element, phased-array, focused, rotating focused, conformable) for surface and subsurface defect detection in conductive materials, including specific/custom flexible probes for damaged or difficult-access surfaces.
• Automated and Semi-Automated NDT Systems Fully automated testing systems, multi-axis robotic systems for flat or complex surfaces, and semi-automatic systems for difficult-access areas. Used for applications such as 1450 MW PWR vessel bi-metallic welds inspection and areas requiring inspected area tracking.
• Digital Magnetic Testing (DMT) Digital magnetic testing technology using magnetic fields generated by electromagnets to detect indications in ferromagnetic parts. When magnetic field lines encounter an indication they are diverted and detected by a sensor, producing characteristic signals that are easy to interpret.
• Ultrasonic Imaging and Time Reversal Advanced volume testing technology using phased-array probes with advanced algorithms and innovative electronics to extend inspection capabilities in materials with complex geometries or low ultrasound permeability.
• Artificial Intelligence for NDT AI application for processing Non-Destructive Testing data, particularly televisual inspections. Eliminates lighting difficulties, sends real-time alerts for anomalies, and produces excellent results for surface defect detection (cracks, scratches, porosity) on complex surfaces, including hybrid AI plus physical model approaches.
• Smart Trajectory Inspection trajectory solution for NDT applications, addressing the positioning and path-planning needs of inspection probes on complex reactor component geometries. Presented at COFREND 2026 Days.
• Development and Qualification of NDT Equipment Custom development, qualification, and supply of specific NDT equipment including inspection robots, probes, and automated systems for nuclear utilities, qualified to international codes (RSE-M, ASME, KTA).
• In-Service Inspection Services for Nuclear Reactors On-site automated NDT inspection services for nuclear power plant primary circuit components, including reactor pressure vessels, steam generator tubes, and primary circuit components. Approximately 100 on-site interventions performed per year across France, Belgium, and internationally.
