A study led by ORNL answers a decades-old question in nuclear science: Do tiny pores in graphite affect nuclear reactor performance?
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.
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.
Eight cadets spent the summer embedded alongside scientists in the Nuclear Energy and Fuel Cycle and Physics Divisions, supporting specialized projects ranging from nuclear fuel chemistry to instrumentation, advancing their knowledge while contributing
The Department of Energy’s Oak Ridge National Laboratory has been selected to lead two new research collaborations and partner on two others under the Fusion Innovation Research Engine, or FIRE, Collaboratives program.
A new patent granted to ORNL researchers redefines how nuclear systems are validated, offering a faster path to next-generation nuclear energy.
ORNL has been selected to lead three research collaborations with fusion industry partners as part of the 2025 cohort of the Innovation Network for Fusion Energy program.
Nuclear energy is a leading option to power space exploration, but its success depends on reactors that can operate autonomously.
A key milestone in the pursuit of fusion energy is achieving a high “triple product,” an important metric of the temperature and density of a burning plasma and how well it is confined.
