Framatome Qualifies Ultrasonic Inspection Technology for PWR Reactors in the United States

Framatome has qualified its ultrasonic inspection technology for core barrel welds in pressurized water reactors (PWR). The technology, described by the company as unprecedented in the nuclear industry, is designed to apply to all PWR reactor designs currently in operation in the United States. As the global nuclear industry awaits decisive milestones in 2026, the qualification of advanced inspection tools reflects broader efforts to modernize the American fleet. Analyst certifications were conducted by EPRI (Electric Power Research Institute) under its PDI (Performance Demonstration Initiative) program, ensuring compliance with strict industry standards.

A 100% Success Rate in EPRI Certification

During the qualification process, Framatome analysts recorded a 100% success rate, according to the company. This result underlines, according to Framatome, the robustness of the technology and the expertise of the teams involved. Tony Robinson, CEO of Framatome Inc., stated that this achievement "underscores the unrivaled expertise and collaborative strength of Framatome teams", adding that the technology would establish "a new standard of excellence in nuclear inspections". This positioning comes as policymakers, including Germany's energy minister, who denounced the nuclear phase-out as a major strategic mistake, reassess past energy decisions.

Framatome says it is now positioned to deliver this service to all PWR reactors operating in the United States. Starting this year, the company plans to conduct seven inspections using this technology, on reactors with and without neutron thermal shields, during planned outages. The company describes this qualification as the culmination of several years of work.

Qualification Extension Planned for Q2 2026

The qualification will be extended in the second quarter of 2026, once EPRI has provided the required demonstration elements. This next step accompanies new requirements applicable to nuclear inspections in 2026, under the revised EPRI MRP-227, Rev. 2-A guide on materials reliability. With a workforce of more than 22,000 employees, Framatome aims to extend this inspection service to the entire U.S. PWR fleet.
