Framatome has reached a major milestone in nuclear inspection technology with the successful qualification of the industry's first ultrasonic weld inspection technique for pressurized water reactor (PWR) core barrels. This breakthrough will apply to all designs of PWR reactors currently operating in the U.S. fleet.
During the qualification process, Framatome analysts achieved a 100% pass rate, an outcome that highlights both the robustness of the new technique and the expertise of the team behind it. Analyst certifications are managed through the Electric Power Research Institute's (EPRI) Performance Demonstration Initiative (PDI) program, ensuring compliance with stringent industry standards.
Looking ahead, the qualification scope is set to expand in the second quarter of 2026, once EPRI provides the required demonstration components. This next phase supports emerging industry inspection requirements outlined in the Materials Reliability Program guidelines (MRP‑227, Rev. 2-A), which take effect in 2026.
“This achievement underscores Framatome's unmatched expertise and collaborative strength. Our team of skilled analysts and engineers consistently tackle complex challenges and deliver innovative solutions that support the U.S. nuclear fleet reliably and at scale,” said Tony Robinson, President & CEO, Framatome Inc. “By reaching this milestone, we are not only meeting our customers' needs but setting a new standard for excellence in inspection technology.”
The qualification marks the culmination of a multi‑year effort and positions Framatome to deliver this advanced ultrasonic testing service across all PWRs in the U.S. operating fleet. The company is already contracted to perform these inspections including this innovative technology seven times during the 2026 outage season at units with and without a neutron thermal shield.
Framatome remains committed to advancing inspection technologies that enhance safety, reliability, and efficiency across the nuclear industry.
