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.
