Jenifer Shafer, the associate director for technology at the Advanced Research Projects Agency­–Energy (ARPA-E), recently delivered a TEDx talk in which she explained the basic concepts of nuclear waste recycling, including related nonproliferation issues. As Shafer wrote in a post on LinkedIn, “In my talk, I explored the misconceptions surrounding nuclear waste and discuss[ed] the possible emerging opportunities regarding nuclear fuel recycling. It’s crucial that we understand the real potential of nuclear energy, and leveraging our ‘nuclear treasure,’ in shaping a sustainable future.”

A statistical analysis of the factors behind the 2021–22 energy crisis in Europe is the subject of the article “Patterns and correlations in European electricity prices,” published in the journal Chaos: An Interdisciplinary Journal of Nonlinear Science. The study—conducted by researchers at the Institute for Energy and Climate Research at Forschungszentrum Jülich and the University of Cologne, both in Germany, and the Norwegian University of Life Sciences—describes reasons for the surge in energy prices that go beyond the commonly cited cause of Russia’s invasion of Ukraine.

Dutton

The only nuclear reactor in Australia is a small one in the Sydney suburb of Lucas Heights, which has been used to produce medical radioisotopes since 1958. Recently, the Hon. Peter Dutton, Parliament’s leader of the opposition to the Labor-led government, announced his plan to get the country into the nuclear energy business by building five large reactors and two small modular reactors by 2050.

Criticizing the government’s “renewables-only” energy policy, Dutton promised to have the first nuclear reactor operating by the mid-2030s, should his Liberal–National Coalition win power in the next federal election (to be held on or before September 27, 2025). That promise, which would require overturns of existing federal and state bans on nuclear energy, has generated a great deal of controversy in Australia among government officials, political activists, and nuclear engineers.

Donalds praises nuclear, urges microreactor development in Florida

June 17, 2024, 12:02PMANS Nuclear Cafe

Donalds

Byron Donalds, the Republican representative from Florida’s 19th Congressional District, is a well-known proponent of nuclear energy. In his latest op-ed, which appeared in The Floridian, Donalds describes himself as “unabashedly pronuclear” and characterizes his state as a supporter of nuclear power, with four operating reactors providing 69.3 percent of Florida’s carbon-free electricity, powering 2.3 million homes. He emphasizes, however, that “there’s so much nuclear potential yet to be realized in the Sunshine State.”

Environmental benefits: Donalds notes that nuclear energy provides “countless environmental benefits” to Floridians, as well as reliable electricity. The 1,132 acres on which the state’s St. Lucie nuclear power plant is located have mangrove swamps, beaches, marshes, and other wildlife habitats that are home to more than 180 species of animals—36 of which are endangered or threatened.

A recent article on Australia’s ABC News website highlighted the work of undergraduate physics and engineering students at the University of New South Wales (UNSW) to design, build, and operate their own small nuclear fusion reactor. The ambitious work, known as the AtomCraft project, is being led by associate professor Patrick Burr with the objective of producing a student-built tokamak reactor by the end of 2026.

Australia-based HB-11 Energy and U.K.-based Tokamak Energy have partnered with UNSW for the project.

Research goals: The AtomCraft project has the following research goals for participating students, according to its website:

Our team aims [to] make the world’s first fusion reactor entirely designed, built, and operated by students. And [to] do so in 2 years. You will develop innovative solutions to engineering challenges across many engineering disciplines, work closely with industry partners, and be part a vibrant team of enthusiastic and dedicated people who want to push the boundaries of what is possible with fusion energy.

A new theoretical model about stabilizing plasma in tokamak fusion reactors is described in three papers from a study that was led by research physicist Jason Parisi of Princeton Plasma Physics Laboratory. Two papers—“Kinetic-ballooning-limited pedestals in spherical tokamak plasmas” and “Stability and transport of gyrokinetic critical pedestals”—appear in the International Atomic Energy Agency journal Nuclear Fusion. The other paper—“Kinetic-ballooning-bifurcation in tokamak pedestals across shaping and aspect-ratio”—appears in Physics of Plasmas.

Borisov

Russian space agency Roscosmos has announced its intention to build a nuclear reactor on the lunar surface in collaboration with the China National Space Administration. According to Roscosmos director general Yury Borisov, “Today we are seriously considering a project—somewhere at the turn of 2033–2035—to deliver and install a [nuclear] power unit on the lunar surface together with our Chinese colleagues.” The reactor would apparently be used to supply power to the Russian-Chinese International Lunar Research Station (ILRS), plans for which the two nations unveiled in 2021.

These plans come on top of previously announced plans of the United States and United Kingdom for lunar nuclear reactors.

Plasma oscillation has fusion energy implications

March 20, 2024, 3:00PMANS Nuclear Cafe

Researchers from the University of Rochester in New York and the University of California–San Diego have published a paper in Physical Review Letters describing a previously unknown class of plasma oscillations. In “Space-Time Structured Plasma Waves,” the researchers “demonstrate that electrostatic wave packets structured with space-time correlations can have properties that are independent of the plasma conditions,” such as “density, temperature, ionization state, or details of the distribution functions.” This finding is technologically relevant, the authors note, because “electrostatic waves play a critical role in nearly every branch of plasma physics from fusion to advanced accelerators, to astro, solar, and ionospheric physics.”

Nuclear noted as an answer to electricity demands from data centers

March 12, 2024, 9:30AMANS Nuclear Cafe

The spread of “electricity-hungry data centers and clean-technology factories” throughout the United States is “leaving utilities and regulators grasping for credible plans to expand the nation’s creaking power grid,” according to a recent article in the Washington Post. According to the report, the surge in industrial power requirements due to such factors as innovation in artificial intelligence (AI) and the corresponding construction of large computing infrastructure, is prompting some officials to “look beyond the grid” to ease the “grid bottleneck” and meet electricity demands.

Report: Better public engagement needed from NRC

March 12, 2024, 7:00AMANS Nuclear Cafe

A new report from the Breakthrough Institute has identified challenges and offers recommendations to the Nuclear Regulatory Commission for fostering inclusive and transparent dialogue and engagement with the public.

Improving Nuclear Regulatory Commission Engagement: Enhancement to Ensure Transparency and Collaboration with the Public notes that despite recent agency efforts at improving public engagement, such as through website upgrades and additional community meetings, the NRC still tends to prioritize technical jargon and complex procedures rather than offer clear, accessible communication. This leads to alienating the interested public, including community members and other stakeholders, and fostering misconceptions.
