Imagine you’re constructing a bridge or designing an airplane, and everything appears flawless on the outside. However, microscopic flaws beneath the surface could weaken the entire structure over time.

These hidden defects can be difficult to detect with traditional inspection methods, but a new technology developed by scientists at the U.S. Department of Energy’s Argonne National Laboratory is changing that. Using artificial intelligence and advanced imaging techniques, researchers have developed a method to reveal these tiny flaws before they become critical problems.

Idaho National Laboratory’s newest facility—the Sample Preparation Laboratory (SPL)—sits across the road from the Hot Fuel Examination Facility (HFEF), which started operating in 1975. SPL will host the first new hot cells at INL’s Materials and Fuels Complex (MFC) in 50 years, giving INL researchers and partners new flexibility to test the structural properties of irradiated materials fresh from the Advanced Test Reactor (ATR) or from a partner’s facility.

Materials meant to withstand extreme conditions in fission or fusion power plants must be tested under similar conditions and pushed past their breaking points so performance and limitations can be understood and improved. Once irradiated, materials samples can be cut down to size in SPL and packaged for testing in other facilities at INL or other national laboratories, commercial labs, or universities. But they can also be subjected to extreme thermal or corrosive conditions and mechanical testing right in SPL, explains Colin Judge, who, as INL’s division director for nuclear materials performance, oversees SPL and other facilities at the MFC.

SPL won’t go “hot” until January 2026, but Judge spoke with NN staff writer Susan Gallier about its capabilities as his team was moving instruments into the new facility.

In materials science, understanding the unseen—how materials behave internally under real-world conditions—has always been key to developing new materials and accelerating innovative technologies to market. Moreover, the tools that allow us to see into this invisible world of materials have often been game-changers. Among these, neutron imaging stands out as a uniquely powerful method for investigating the internal structure and behavior of materials without having to alter or destroy the sample. By harnessing the unique properties of neutrons, researchers can uncover the hidden behavior of materials, providing insights essential for advancing nuclear materials and technologies.

Energy secretary Chris Wright outlined his priorities and plans this week, including a focus on modernizing nuclear power and “taking the politics out” of energy discussions, especially as they relate to climate change.

Are you an energy genius? It’s hard to tell whether or not Americans are really aware of the energy that controls our lives, so the following energy quiz should be revealing. The answers are revealed as you take the quiz. Most answers can be found in the pages of the 2024 issues of Nuclear News—so if you’ve been a diligent NN reader you should do fine!

Scoring: Out of 20 questions, 0–5 correct answers means you may need to read up on energy so you’re not at the mercy of others; 6–10 correct answers is a good passing grade (I don’t curve); 11–15 means you’re energy literate; 16–19 means you should be advising Congress; 20 correct answers suggests you’re Mr. Spock reincarnated.

Dear Secretary Wright:

On behalf of the U.S. nuclear professional community, I offer our sincere congratulations to you on your becoming the secretary of energy.

By now, I’m sure you have figured out that “Department of Energy” is a misnomer. If the Department of Government Efficiency ever requires truth in advertising, the DOE should be renamed the “Department of Nuclear Weapons, Security, Cleanup, and Sundry Energy and Science Programs.” That’s because more than 60 percent of the DOE’s budget is dedicated to “atomic energy defense activities”—making sure our nuclear bombs work, our aircraft carriers and submarines sail, and our Cold War messes get cleaned up.

Texas A&M chancellor John Sharp has announced that the university could soon become a home to small modular reactors from four advanced nuclear companies: Kairos Power, Natura Resources, Terrestrial Energy, and Aalo Atomics.

Cape Fear Community College (CFCC) in Wilmington, N.C., has appointed Kelli Davis its first Nuclear Technology program director. Davis has nearly 20 years of experience in nuclear power, including roles in chemistry, operations, and environmental supervision.

An official ground breaking on Monday for Swedish nuclear company Blykalla’s advanced reactor testing site marked a pivotal step in putting decades of research into action.

To better educate customers and stakeholders on its technology, NANO Nuclear Energy has opened a new demonstration facility in Westchester County, N.Y., that offers an up-close look at nonnuclear parts and components of the four microreactors the company has in development.
