Oak Ridge National Laboratory researchers have developed a method to simplify one step of radioisotope production — and it’s faster and safer.

For fusion energy, scientists must generate, confine and sustain a superhot gas called plasma — heated to 10 times the temperature of the center of the sun — to cause a fusion reaction. Although terrestrial plasmas can be confined magnetically, what materials can withstand near such high temperatures and the relentless impact of energetic neutrons? That question is central to the development of economical fusion power plants to provide abundant and carbon-free energy. Scientists at the Department of Energy’s Oak Ridge National Laboratory have been working with Japanese scientists under the Japan-U.S. Fusion Cooperation Program for decades to determine the answer.

Ken Herwig’s career spanning two-and-a-half decades at ORN includes designing, building and rebuilding scientific instruments used to study the behavior of particles—including SNS’s first instrument, named BASIS.

When opportunity meets talent, great things happen. The laser comb developed at the Department of Energy’s Oak Ridge National Laboratory serves as such an example. This advanced technique, developed by laser scientist Yun Liu, allows physicists to take measurements of particle beams in superconducting linear accelerators in real-time without affecting operations. The measurement captures critical information about changes in the distribution of beam particles. The development and use of this technique solidifies ORNL’s leadership in beam instrumentation and leads the advancement of high-power proton accelerators.

Like most scientists, Chengping Chai is not content with the surface of things: He wants to probe beyond to learn what’s really going on. But in his case, he is literally building a map of the world beneath, using seismic and acoustic data that reveal when and where the earth moves. Yet earthquakes are not the focus of Chai’s research at the Department of Energy’s Oak Ridge National Laboratory. He is using these waves to make waves — creating new opportunities for developing clean energy and enhancing sensing capabilities around nuclear reactors.

Oak Ridge National Laboratory researchers, in collaboration with Enginuity Power Systems, demonstrated that a micro combined heat and power prototype, or mCHP, with a piston engine can achieve an overall energy efficiency greater than 93%.

Stan David, retired scientist and Corporate Fellow Emeritus at the Department of Energy’s Oak Ridge National Laboratory, was awarded the Joining and Welding Science Award from the Joining and Welding Research Institute at Osaka University, Japan.

Rigoberto Advincula, a renowned scientist at the Department of Energy’s Oak Ridge National Laboratory and professor of Chemical and Biomolecular Engineering at the University of Tennessee, has won the Netzsch North American Thermal Analysis Society (NATAS) Fellows Award for 2023.

Nature-based solutions are an effective tool to combat climate change triggered by rising carbon emissions, whether it’s by clearing the skies with bio-based aviation fuels or boosting natural carbon sinks. At the Department of Energy’s Oak Ridge National Laboratory, scientists are leading research to transform plants into key drivers of decarbonization, from creating biomass crops for new fuels to enhancing the ability of plants to absorb and store carbon.

Oak Ridge National Laboratory joins four other national laboratories — Idaho, Los Alamos, Lawrence Livermore and Lawrence Berkeley — that have institutes named after nuclear chemist and Nobel Prize winner Glenn T. Seaborg.
