(IDAHO FALLS, Idaho) — The U.S. Department of Energy’s Idaho Operations Office has approved a key safety document for the MARVEL microreactor at Idaho National Laboratory. The approved document, called a Preliminary Documented Safety Analysis (PDSA), marks a major milestone toward building and operating the microreactor for research, development and end-user demonstrations.

The Department of Energy’s Oak Ridge National Laboratory is propelling grid resilience through a partnership with regional utility EPB of Chattanooga that will demonstrate advanced microgrid capabilities to reduce customer power outages. 

Researchers at Oak Ridge National Laboratory and collaborators found a new way to control how heat moves through certain ceramic materials. By applying an electric field, they changed the behavior of tiny vibrations in the material (called phonons), making heat travel much more easily in the direction of the field—nearly tripling thermal conductivity compared with other directions. The discovery could help create solid-state devices that manage heat more efficiently in electronics, energy systems and other technologies.

Vipin Kumar, a composites manufacturing researcher at the Department of Energy's Oak Ridge National Laboratory, has been named one of 21 rising professionals nationwide for the 2026 Emerging Leaders Program of the American Composites Manufacturers Association.

(IDAHO FALLS, Idaho) — The National Reactor Innovation Center’s Molten Salt Thermophysical Examination Capability is set to begin operation in March, marking a pivotal step toward advancing reactor and fuel cycle technologies.

Prometheus Grand Challenge aims to deploy commercial-scale nuclear reactors in years, not decades.

IDAHO FALLS, Idaho —The Idaho National Laboratory and NVIDIA have partnered to advance nuclear energy deployment through artificial intelligence. The collaboration aims to accelerate advanced nuclear reactor deployment and reduce costs.

The Department of Energy’s Oak Ridge National Laboratory and Kairos Power have entered into a $27 million strategic partnership to accelerate the technology needed to deploy a new generation of advanced nuclear reactors and support U.S. nuclear energy goals.  The Department of Energy’s Oak Ridge National Laboratory and Kairos Power have entered into a $27 million strategic partnership to accelerate the technology needed to deploy a new generation of advanced nuclear reactors and support U.S. nuclear energy goals.  

Separated by an ocean and more than a decade, innovative experiments with 31 tin isotopes having either a surplus or shortage of neutrons show how neutrons influence nuclear stability and element formation. The experiments, conducted between 2002 and 2012 at Oak Ridge National Laboratory and more recently at CERN, provide knowledge that impacts nuclear energy and national security applications.

Food scraps, manure and sewage are natural byproducts of the U.S. agricultural industry. They are also rich in biogas, a mixture that contains methane and other valuable chemicals. A team of researchers at Sandia National Laboratories are developing chemistry that could help capture methane from biogas and separate it from other gases so it can be put to good use.
