It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.

Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

The Duane Arnold nuclear power plant in Iowa could see new life, according to NextEra Energy chief executive officer John Ketchum.

“There would be opportunities and a lot of demand from the market if we were able to do something with Duane Arnold,” Ketchum said on Wednesday this week during the company’s second-quarter earnings call.

Eielson Air Force Base in central Alaska has been the preferred location to demonstrate the benefits of microreactors to the U.S. Air Force—and by extension the Defense Department—since 2018. Now, a protracted solicitation process is nearing an end, and the Air Force and the Defense Logistics Agency Energy (DLA Energy) expect to announce a final procurement decision by the end of the summer—or about one year after Oklo Inc. announced that it had been tentatively selected to supply a microreactor under a 30-year power purchase agreement.

A plutonium target bombarded with a beam of titanium-50 in Lawrence Berkeley National Laboratory’s 88-Inch Cyclotron for 22 days has yielded two atoms of the superheavy element 116, in a proof of concept that gives Berkeley Lab researchers a path to pursue the heaviest element yet—element 120. The result was announced July 23 at the Nuclear Structure 2024 conference; a paper has been submitted to the journal Physical Review Letters and published on arXiv.

Imagine a place where children and adults can learn together about nuclear science as a carbon-free energy source that can be an answer to climate change. Guests can experience a cloud chamber, remotely inspect equipment with a drone, and hold a simulated low-enriched uranium fuel pellet. On Saturday, July 6, such a place actually existed for three hours. That place was the Discovery Place Science Museum in Charlotte, N.C. Ryan Leung, a Discovery Place experience specialist, led a team of local nuclear energy industry volunteers and representatives from the American Nuclear Society and Women in Nuclear to organize and execute an Energy Summit.

The magnetic mirror fusion concept dates to the early 1950s, but decades ago it was sidelined by technical difficulties and researchers turned to tokamak fusion in their quest for confinement. Now it’s getting another look—with significantly more powerful technology—through WHAM, the Wisconsin HTS Axisymmetric Mirror, an experiment in partnership between startup Realta Fusion and the University of Wisconsin–Madison.

New testing done at China’s Shidaowan nuclear power plant has confirmed its ability to be naturally cooled down, an industry-first milestone for achieving commercial-scale inherent safety, according to researchers.

A public hearing in Kemmerer, Wyo., drew dozens of comments and questions about TerraPower’s plans to build the Natrium nuclear reactor demonstration project in the coming years.

Marzano

President Biden has selected Matthew Marzano as his choice to fill the open seat on the five-member Nuclear Regulatory Commission.

The panel of commissioners has had a vacancy since Jeff Baran’s term as commissioner ended in June 2023.

Marzano currently serves as an Idaho National Laboratory detailee for the U.S. Senate’s Environment and Public Works Committee, advising EPW on policy matters relating to clean air, climate, and energy. Most recently, he advised the committee’s chairman on the ADVANCE Act, legislation designed to prepare the NRC for an expected surge in new nuclear reactor oversight.

A new report based on what its authors call “the definitive American public opinion surveys on climate change and the environment” has found a statistically significant increase in the percentage of survey respondents who think nuclear power is a good way to generate electricity, relative to a survey that asked the same question in 2013. That’s despite evidence that “Americans’ views on climate change have remained remarkably steady.” The new report, Climate Insights 2024: American Understanding of Climate Change, is the product of a 27-year polling partnership led by the Political Psychology Research Group at Stanford University and Resources for the Future (RFF), and it was released July 15.
