【SMM Stainless Steel Update】Oak Ridge National Laboratory (ORNL) has successfully tested two 3D-printed experimental capsules made of 316H stainless steel at its High Flux Isotope Reactor (HFIR). With proven high-temperature strength, corrosion and radiation resistance, the capsules endured a month-long irradiation and were removed intact, confirming their nuclear-grade reliability. The achievement highlights additive manufacturing’s potential to produce critical reactor components more cost-effectively and efficiently, accelerating nuclear materials innovation.
