In the frame of the ITER project, and under various contracts with F4E, Tecnatom (a member of the Westinghouse Group) has developed advanced phased-array ultrasonic techniques (PAUT) tailored to the stringent requirements of nuclear fusion environments. This NDT service targets challenging welds and materials, specifically the 316-grade stainless steel, used in Tokamak reactors, such as the Vacuum Vessel, Toroidal Field Coil Cases, Pre-Compression Rings, and First Wall Panels. This PAUT solution excels in highly attenuating materials like austenitic welds and composites, offering inspection precision in conditions where standard techniques may struggle.

Technology assets

• Expertise in phased-array ultrasonic techniques for precise inspection of highly attenuating materials, such as austenitic welds and composites.
• Proven qualification methodology in line with French nuclear codes for stainless steel (grade 316), specific to fusion reactor components.
• Modular and adaptable inspection service, offering high-performance non-destructive testing (NDT) across fusion and fission reactors, as well as industrial sectors like oil and gas.
