ORNL researchers developed a machine learning model that generates realistic tungsten microstructure images, helping fill gaps in costly experimental data. The approach supports virtual experiments to design more durable fusion reactor components and reduce maintenance costs.
Rinkle Juneja, an R&D staff scientist at ORNL, has been recognized as an Early Career Distinguished Presenter by the Materials Research Society and was selected to represent ORNL on the “Materials Research at the U.S. DOE National Laboratories” panel at the MRS Fall Meeting.
As the U.S. reimagines its nuclear future, researchers at ORNL are experimenting with molten lead and next-generation materials to reinvent a classic reactor design for a new era of innovation. To evaluate the alloy’s performance in these conditions, researchers are testing AFA samples in eight small rabbit capsules encased in solid lead in ORNL’s High Flux Isotope Reactor.
ORNL received more than $5 million from DOE;s Technology Commercialization Fund to advance research in grid security, artificial intelligence, nuclear energy and advanced manufacturing, helping move lab innovations toward industry use.
Scientists at ORNL used Raman spectroscopy to analyze uranium oxide samples derived from uranium ore concentrates. Although traditional methods showed the samples were structurally similar, the technique revealed molecular-level differences after high-temperature processing. The findings suggest Raman spectroscopy can help identify variations among uranium materials.
Army Major Mike Ecklund is currently embedded at ORNL through the Army’s Training with Industry program. At the lab, he works with scientists to study the behavior of nuclear materials in long-term storage, translating research findings into practical insights.
Researchers at ORNL will share their discoveries and innovations at DOE’s Advanced Research Projects Agency-Energy Energy Innovation Summit in San Diego, California.
ORNL is not only a leading research institution for medical isotopes, it is also the United States’ biggest producer of isotopes for both medical and other purposes. The lab’s ability to produce critical isotopes will be supercharged over the coming years with three major new facilities.
Researchers at ORNL have captured first-of-a-kind optical measurements during accident testing of commercially irradiated nuclear fuel cladding. Using a technique called digital image correlation, the test captured detailed measurements of the cladding’s behavior during a simulated loss-of-coolant accident.
A new approach to nuclear fuel developed at ORNL could enhance the performance of new light water nuclear reactors. The Uranium Dioxide Liquid Metal Suspension (ULIMES) fuel concept offers a next step for fuel innovation.
