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.
Researchers at ORNL have uncovered a path to design superionic polymer electrolytes for solid-state batteries and other energy applications that could help ensure a future of abundant and reliable energy for the United States.
ORNL was recently awarded six Federal Laboratory Consortium awards, including the 2026 Excellence in Technology Transfer Award, for technology commercialized by Element3 that enables the extraction of lithium from oil and gas wastewater.
The University of Tennessee, Knoxville, and Oak Ridge National Laboratory have jointly recruited Deep Jariwala, a nationally recognized leader in quantum materials and next-generation electronic devices, as the UT-ORNL governor’s chair for quantum devices.
SNS celebrates 20 years of scientific achievements enabled by safe, reliable operations driven by its target system. Since coming online in 2006, SNS has celebrated many milestones, including being the first to successfully incorporate a liquid mercury target. This feature discusses the plans to incorporate artificial intelligence to support the target as well as what is next for the second target station.
Researchers at ORNL developed a method to convert a commonly discarded hydrocarbon polymer into gasoline- and diesel-like fuels. The team has applied for a patent for the discovery, which treats polyethylene — the stuff of white cutting boards and shopping bags — with aluminum chloride-containing molten salts that serve as both solvent and catalyst. If scaled beyond the laboratory, the process could strengthen U.S. energy security and industrial competitiveness.
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.
Adrian Sabau, a computational materials scientist at ORNL, has received the Materials Processing & Manufacturing Division (MPMD) Distinguished Service Award from The Minerals, Metals & Materials Society (TMS), recognizing his sustained contributions to the field and service to the professional community.
Breast cancer survivor Missy Baird now supports isotope production at ORNL, contributing to treatments for the disease she once faced. Her decades-long career reflects resilience, leadership and a commitment to advancing the lab’s mission.
Ann Weaver has been named chief operating officer for Oak Ridge National Laboratory. Weaver has established a record of leading large, complex organizations toward improved performance, reliability, efficiency, and effectiveness in a 22-year career at ORNL.
