91����

Jeremy Busby has been named associate laboratory director for the Fusion and Fission Energy and Science Directorate at the Department of Energy’s 91����, effective Jan. 1.

The Oppenheimer Science and Energy Leadership Program has selected 91����’s Jens Dilling and Christian Petrie as fellows for its 2023 cohort.

91���� physicist Elizabeth “Libby” Johnson (1921-1996), one of the world’s first nuclear reactor operators, standardized the field of criticality safety with peers from ORNL and Los Alamos National Laboratory.

Steven Arndt, distinguished R&D staff member in the Nuclear Energy and Fuel Cycle Division at ORNL, began a one-year term on June 16 as the 68^th President of the American Nuclear Society.

Friederike (Rike) Bostelmann, who began her career in Germany, chose to come to ORNL to become part of the Lab’s efforts to shape the future of nuclear energy.

To achieve practical energy from fusion, extreme heat from the fusion system “blanket” component must be extracted safely and efficiently. ORNL fusion experts are exploring how tiny 3D-printed obstacles placed inside the narrow pipes of a custom-made cooling system could be a solution for removing heat from the blanket.

Scientists are using 91����’s Multicharged Ion Research Facility to simulate the cosmic origin of X-ray emissions resulting when highly charged ions collide with neutral atoms and molecules, such as helium and gaseous hydrogen.

91���� is debuting a small satellite ground station that uses high-performance computing to support automated detection of changes to Earth’s landscape.

To study how space radiation affects materials for spacecraft and satellites, 91���� scientists sent samples to the International Space Station. The results will inform design of radiation-resistant magnetic and electronic systems.

ORNL and the Tennessee Valley Authority, or TVA, are joining forces to advance decarbonization technologies from discovery through deployment through a new memorandum of understanding, or MOU.
