It’s been less than two years since Germany shuttered its three remaining nuclear plants on April 15, 2023—the culmination of a decision reached during the backlash following the Fukushima Daiichi accident in Japan in 2011.

An International Atomic Energy Agency team has concluded that Spain has shown a strong commitment to nuclear and radiation safety, confirming that the country has successfully enhanced its regulatory framework, fully implementing IAEA recommendations made in 2018.

The top three utilities in Arizona are teaming up to explore opportunities to add nuclear generation facilities in the state.

Arizona Public Service (APS), Salt River Project (SRP), and Tucson Electric Power (TEP) announced in a February 5 news release that they are working together to assess possible sites, including retiring coal plants. The group is looking at possibilities for both small modular reactors—units generating 300 MW or less—and potential large reactor projects, which could generate nearly five times the power.

We push materials to their breaking point for you.

Millions of Americans rely on nuclear energy. It provides 20 percent of electrical power in the United States—24 hours a day, 7 days a week, 365 days a year. To maintain this reliability, every material used in our reactors must work safely and efficiently.

I’m part of a team of world-class scientists, engineers, and technical professionals at Oak Ridge National Laboratory, testing and evaluating materials designed to thrive in one of the most complex environments on Earth. Nuclear reactors experience heavy stress loads, high temperatures, corrosive environments, and intense radiation fields. Combined, these forces can substantially impact the performance of cladding or other structural materials. We want to know where and under what conditions materials may fail to keep a reactor running safely and reliably.

The Nuclear Regulatory Commission has published its final environmental impact statement for the proposed subsequent license renewal (SLR) for Oconee nuclear power plant's Units 1, 2, and 3.

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.
