Four first-of-a-kind 3D-printed fuel assembly brackets, produced at the Department of Energy’s Manufacturing Demonstration Facility at Oak Ridge National Laboratory, have been installed and are now under routine operating conditions at the Tennessee Valley Authority’s Browns Ferry Nuclear Plant Unit 2 in Athens, Alabama.
The Department of Energy’s Argonne National Laboratory is proud to welcome five new FY21 Maria Goeppert Mayer Fellows to campus, each chosen for their incredible promise in their respective fields.
The Smith College undergraduate is analyzing data relevant to nuclear reactor science.
The Daya Bay Reactor Neutrino Experiment collaboration – which made a precise measurement of an important neutrino property eight years ago, setting the stage for a new round of experiments and discoveries about these hard-to-study particles – has finished taking data. Though the experiment is formally shutting down, the collaboration will continue to analyze its complete dataset to improve upon the precision of findings based on earlier measurements.
ORNL has 3D printed a channel bracket to go into reactors at Browns Ferry Nuclear Plant this spring, to demonstrate the viability of pre-qualified additively manufactured reactor components.

The Transformational Challenge Reactor will use novel materials. Researchers are testing their performance in a reactor core by irradiating them in the High Flux Isotope Reactor.
Through DOE’s Technology Commercialization Fund, the national lab-startup team will develop “nanocages” for nuclear applications.
As an intern for the National Nuclear Data Center, Pedro Rodríguez is working to resolve a 70-year-old problem in nuclear physics. He and his mentor are figuring out a way to simplify one of the steps for ensuring nuclear reactors can be modeled correctly.
Researchers at the Department of Energy’s Oak Ridge National Laboratory are refining their design of a 3D-printed nuclear reactor core, scaling up the additive manufacturing process necessary to build it, and developing methods to confirm the consistency and reliability of its printed components.
A software package, 10 years in the making, that can predict the behavior of nuclear reactors’ cores with stunning accuracy has been licensed commercially for the first time.
Neutron scattering instruments at ORNL’s HFIR and SNS are undergoing upgrades which will enable them to study magnetic phenomena previously not possible in the US. Incorporating a device for spherical neutron polarimetry enables the ability to characterize complex magnetic systems in new dimensions for materials that could be developed for enhanced data storage and quantum computing technologies.
Researchers at Sandia National Laboratories are developing a promising new way to prevent the spread of radioactive contamination and contain the hot molten mass that develops within a nuclear reactor during a catastrophic accident. During a three-year Laboratory Directed Research and Development project, a team of scientists discovered and patented a process for injecting sand-like minerals into the core of a nuclear reactor during an accident to contain and slow down the progression of a meltdown.
