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.

The Oak Ridge Leadership Computing Facility’s Matt Sieger has been named the project director for the OLCF-6 effort. This next OLCF undertaking will plan and build a world-class successor to the OLCF’s still-new exascale system, Frontier.

Led by Kelly Chipps of the Department of Energy’s Oak Ridge National Laboratory, scientists working in the lab have produced a signature nuclear reaction that occurs on the surface of a neutron star gobbling mass from a companion star. Their achievement improves understanding of stellar processes generating diverse nuclear isotopes.

As a biogeochemist at the Department of Energy’s Oak Ridge National Laboratory, Matthew Berens studies how carbon, nutrients and minerals move through water and soil. In this firsthand account, Berens describes recent fieldwork in Louisiana with colleagues to better understand key processes in coastal ecosystems.

With the world’s first exascale supercomputing system now open to full user operations, research teams are harnessing Frontier’s power and speed to tackle some of the most challenging problems in modern science. Frontier remains in the number one spot on the May 2023 TOP500 rankings, with an updated HPL, or high-performance Linpack, score of 1.194 exaflops. The increase of .092 exaflops, or 92 petaflops, is equivalent to the eighth most powerful supercomputer in the world on the TOP500 List. Engineers at the Oak Ridge Leadership Computing Facility, which houses Frontier and its predecessor Summit, expect that Frontier’s speeds could ultimately top 1.4 exaflops, or 1.4 quintillion calculations per second.

ORNL’s electromagnetic isotope separator, or EMIS, made history in 2018 when it produced 500 milligrams of the rare isotope ruthenium-96, unavailable anywhere else in the world. And EMIS technology just keeps getting better, said Brian Egle, who heads the Enrichment Science and Engineering Division’s Stable Isotope Research, Development and Production Section. “It’s capable of, essentially, separating the whole periodic table,” he said.

Kelly Chipps, a nuclear astrophysicist at the Department of Energy’s Oak Ridge National Laboratory, has been appointed to the Nuclear Science Advisory Committee, or NSAC. The committee provides official advice to DOE and the National Science Foundation, or NSF, about issues relating to the national program for basic nuclear science research.

Tomonori Saito, a distinguished innovator in the field of polymer science and senior R&D staff member at the Department of Energy’s Oak Ridge National Laboratory, was honored on May 11 in Columbus, Ohio, at Battelle’s Celebration of Solvers.

Nonfood, plant-based biofuels have potential as a green alternative to fossil fuels, but the enzymes required for production are too inefficient and costly to produce. However, new research is shining a light on enzymes from fungi that could make biofuels economically viable.
