Argonne scientists use AI to detect hidden defects in stainless steel
Imagine you’re constructing a bridge or designing an airplane, and everything appears flawless on the outside. However, microscopic flaws beneath the surface could weaken the entire structure over time.
These hidden defects can be difficult to detect with traditional inspection methods, but a new technology developed by scientists at the U.S. Department of Energy’s Argonne National Laboratory is changing that. Using artificial intelligence and advanced imaging techniques, researchers have developed a method to reveal these tiny flaws before they become critical problems.

Decontamination of fuel pins is an important process step in nuclear fuel fabrication. Decontamination assumes greater significance with respect to fuels containing plutonium, owing to both plutonium's high radiotoxicity arising from its long biological half-life and its relatively short radioactive half-life. The advantages of using a laser to decontaminate such radioactive surfaces over conventional cleaning techniques are well recognized. This paper describes detailed process optimization and field implementation of laser-assisted decontamination of fuel pins of the Prototype Fast Breeder Reactor (PFBR). A short-pulsed Nd-YAG laser has been effectively used to decontaminate the fuel pins by exposing their outer surface to laser radiation of an appropriate fluence. The laser parameters were controlled to achieve the required cleaning without causing any clad surface damage. Achievement of such was confirmed by evaluating the laser-cleaned surface using scanning electron microscopy, chemical composition studies by electron probe microanalysis, and Vicker's microhardness test.
