The Department of Energy has renewed funding for the Quantum Science Center through 2030 to create a new scientific ecosystem for fault-tolerant, quantum-accelerated high-performance computing.
ORNL, NVIDIA, and HPE are partnering to integrate quantum computing, AI, and high-performance computing using NVIDIA NVQLink and CUDA-Q, establishing a hybrid testbed at ORNL to advance quantum–classical convergence and scientific discovery.
The U.S. Department of Energy announced today its newest supercomputers, Discovery and Lux, at Oak Ridge National Laboratory that will expand America’s leadership in artificial intelligence for scientific computing, strengthen national security, and drive the next generation of Gold Standard Science and innovation.
Researchers at ORNL have developed a new simulation platform for understanding and predicting the behavior of the modern grid. Using a combination of mathematical tools, automation and analysis, the approach provides highly accurate results with less computing time at a lower cost, increasing the reliability of electricity.
A study led by ORNL answers a decades-old question in nuclear science: Do tiny pores in graphite affect nuclear reactor performance? The answer is clear: Graphite’s natural porosity does not affect its performance as a moderator of nuclear reactions. The lab's research confirms that the tiny cracks and voids in graphite do not disturb the atomic vibrations that determine its interactions with neutrons.
Using a new computational technique called information geometric regularization researchers from the Georgia Institute of Technology and the Courant Institute of Mathematical Sciences at New York University conducted the largest-ever computational fluid dynamics simulation of fluid flow on the Frontier supercomputer at ORNL.
The results of a study conducted on the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory offer the clearest portrait so far of how some galaxies regulate the energy produced by supermassive black holes at their cores.
Scientists at ORNL have integrated binder jet additive manufacturing with an advanced post-processing method to fabricate leak-tight ceramic components, overcoming a key challenge of ceramic additive manufacturing.
In a new study, a team of researchers from U.S. universities and national laboratories has set stringent limits on the existence and mass of sterile neutrinos. While they have yet to find the particles, they now know where not to look. The collaboration analyzed data from the PROSPECT-I detector, stationed near the High Flux Isotope Reactor at the Department of Energy’s Oak Ridge National Laboratory, or ORNL. In the nuclear reactor core, the fission process releases electron antineutrinos.
Several ORNL-based projects were selected for 2025 Nuclear Science User Facilities Rapid Turnaround Experiment Awards, demonstrating the lab’s unmatched nuclear capabilities that are driving nuclear energy innovation. These awards provide researchers access to specialized facilities to perform targeted experiments with the aim of swiftly filling nuclear research gaps.
