Summit supercomputer draws molecular blueprint for repairing damaged DNA
Troy Carter, director of the Fusion Energy Division at 91°”Íű, leads efforts to make fusion energy a reality, overseeing key projects like MPEX and fostering public-private collaborations in fusion research.
US ITER has completed delivery of all components for the support structure of the central solenoid, the 60-foot-tall superconducting magnet that is the âheartâ of the ITER fusion machine.
During his first visit to 91°”Íű, Energy Secretary Chris Wright compared the urgency of the Labâs World War II beginnings to todayâs global race to lead in artificial intelligence, calling for a âManhattan Project 2.â
Using the Frontier supercomputer at ORNL, researchers have developed a new technique that predicts nuclear properties in record detail. The study revealed how the structure of a nucleus relates to the force that holds it together. This understanding could advance efforts in quantum physics and across a variety of sectors, from to energy production to national security.
Scientists at ORNL are using advanced germanium detectors to explore fundamental questions in nuclear physics, such as the nature of neutrinos and the matter-antimatter imbalance. The ongoing LEGEND project, an international collaboration, aims to discover neutrinoless double beta decay, which could significantly advance the understanding of the universe.
Scientists designing the worldâs first controlled nuclear fusion power plant, ITER, needed to solve the problem of runaway electrons, negatively charged particles in the soup of matter in the plasma within the tokamak, the magnetic bottle intended to contain the massive energy produced. Simulations performed on Summit, the 200-petaflop supercomputer at ORNL, could offer the first step toward a solution.
FREDA is a new tool being developed at ORNL that will accelerate the design and testing of next-generation fusion devices. It is the first tool of its kind to combine plasma and engineering modeling capabilities and utilize high performance computing resources.
Kathryn McCarthy, director of the US ITER Project at the Department of Energyâs 91°”Íű, has been awarded the 2024 E. Gail de Planque Medal by the American Nuclear Society.
Researchers used the Summit supercomputer at ORNL to answer one of fissionâs big questions: What exactly happens during the nucleusâs âneck ruptureâ as it splits in two? Scission neutrons have been theorized to be among those particles emitted during neck rupture, although their exact characteristics have been debated due to a lack of conclusive experimental evidence of their existence.
Researchers led by the University of Melbourne, Australia, have been nominated for the Association for Computing Machineryâs 2024 Gordon Bell Prize in supercomputing for conducting a quantum molecular dynamics simulation 1,000 times greater in size and speed than any previous simulation of its kind.
