The thriving gray wolf population in the Chernobyl exclusion zone (CEZ) has been the subject of recent media interest. While some sensationalist reports have referred to “mutant wolves” with “superpowers,” other news outlets have offered more sober discussions of the science behind the story.

Cara N. Love, a biologist and postdoctoral fellow in the Department of Ecology and Evolutionary Biology at Princeton University, has been following the wolf population. Her research in the Chernobyl exclusion zone (CEZ) in Ukraine and Polesie State Radioecological Reserve in Belarus is helping biologists understand how nature adapts to chronic radiation exposure.

Richland critiques “home, safety, [and] whiteness” of proud nuclear company town

Lusztig

The documentary film Richland, which won awards at the Tribeca Festival and Sheffield (U.K.) DocFest last year, continues to gain exposure. Directed by Irene Lusztig, a self-described “feminist filmmaker, archival researcher, educator, and seamstress,” the documentary explores the community and “nuclear origin story” of Richland, Washington, a town that was built by the U.S. government to house Hanford Site workers who made the weapons-grade plutonium for the atomic bombs of the Manhattan Project.

Washington State University offered a free screening of the documentary last week at its main Pullman campus, followed by a discussion with the director and Robert Franklin, an assistant professor in history at the university’s Tri-Cities campus and the assistant director and archivist for the Hanford History Project.

Cold War nuclear artifact prompts police call

February 12, 2024, 10:31AMANS Nuclear Cafe

It’s not every day that local police departments find nuclear missiles in garages. But that’s what the bomb squad of the Bellevue, Washington, police department encountered on February 1 when they responded to a call. Fortunately, the missile turned out to be inert. It was a McDonnell Douglas AIR-2A Genie unguided air-to-air rocket (once known as an MB-1), which was designed to carry a 1.5 kiloton W25 nuclear warhead, but there was no warhead on the rusted rocket in the garage.

Armenia’s positive lessons learned on nuclear power

February 6, 2024, 9:30AMANS Nuclear Cafe

Danagoulian

Areg Danagoulian, associate professor of nuclear science and engineering at Massachusetts Institute of Technology, draws on his experiences growing up in Soviet-era Armenia to argue that nuclear energy is crucial to “help strengthen liberal democracies that are being unprecedently threatened” by what he calls authoritarian regimes, such as Russia and China.

Disasters both natural and man-made: In his essay “How Nuclear Power Saved Armenia,” published by the Bulletin of the Atomic Scientists, Danagoulian recalls the shutdown of Armenia’s Metsamor nuclear reactors in 1989 in the wake of fears generated by the 1986 Chernobyl accident, which “dramatically undermin[ed] public trust in nuclear power as a safe source of energy.” He asserted that “the public perception of danger from nuclear power was magnified by the outrageous lies that the Soviet leadership spread about the disaster, the obvious incompetence and irresponsibility of the Soviet nuclear designers who built and operated the Chernobyl reactor, and the poorly executed cleanup efforts, which were compounded by miscalculations and gross mistakes.”

Informal survey asks when the next U.S. nuclear plant will come on line

January 23, 2024, 12:00PMANS Nuclear Cafe

Wesoff

According to an admittedly informal and unscientific survey of people from online “nuclear affinity groups” conducted by Eric Wesoff, the editorial director for clean energy newsroom Canary Media, there is no consensus regarding when the next nuclear power plant will come on line in the United States. Wesoff recently reported that upon polling his nuclear-connected network on LinkedIn, X, and Reddit, he found that “the responses were all over the map.”

Nuclear renaissance? Wesoff was prompted to try his survey about the expected date for the next nuclear plant because “conditions are perfect for the American nuclear renaissance.” He cited strong support for the nuclear industry from the Department of Energy as well as from public opinion polls and online “influencers.” He thought therefore that he would find confident predictions for when the next new U.S. reactor would go on line. Instead, he found uncertainty and varied responses.

A case of “nuclear power on the brain”

January 22, 2024, 12:22PMANS Nuclear Cafe

Crownhart

“I’ve got nuclear power on the brain this week.” So writes climate and energy reporter Casey Crownhart in a recent edition the Spark, the MIT Technology Review’s climate newsletter. In her article, Crownhart describes how, while she was conducting research on advanced nuclear energy for another article, she “went down some rabbit holes on . . . potential options for future nuclear plants” and has “reached new levels of obsession” about nuclear energy.

Nuclear primer: Crownhart’s article could serve as a primer for both basic nuclear and advanced nuclear technologies. She begins by discussing the “two absolutely essential pieces” of conventional nuclear power plants—namely, the enriched uranium fuel and the pressurized water cooling system—and explains that the cooling system “keeps the whole thing from getting too hot and causing problems.”

Investors continue to be bullish on uranium, according to a number of recent news reports. Stockhead recently trumpeted, “Uranium has started 2024 the same way it ended 2023—like a bull in a china shop. Spot prices are now agonizingly close to US$100/lb for the first time since 2008, with term pricing not far behind.” Similarly, Mining.com noted, “The spot price of uranium continues to rise, boosted by pledges to triple nuclear power by mid-century, supply hiccups from producers such as Cameco . . . , and the looming threat of a ban on Russian exports to the West.”

Energy secretary Jennifer Granholm visited the Clinch River Nuclear Site in Oak Ridge, Tenn., on December 5 to highlight the Biden administration’s support for the Tennessee Valley Authority’s advanced nuclear technology program.

Granholm indicated that the administration is willing to provide funding for the nation’s first commercial small modular reactor at the site. “Excited to see a shovel in the ground, hopefully in a few more years,” she said. “TVA is leading on small modular reactors with this site. Everybody’s looking to TVA to make sure that this can actually happen.”

Survey reveals support for, but misconceptions about, nuclear energy

December 6, 2023, 9:30AMANS Nuclear Cafe

Fifty-two percent of Americans either “strongly” or “somewhat” support nuclear energy as part of the United States’ energy mix, with the strongest support among Republicans (59 percent) and self-described independents (53 percent). Support among Democrats is 48 percent. Those are some of the results from the sixth annual American Climate Perspectives Survey conducted by ecoAmerica.

A fourth time around for World Nuclear Energy Day

December 1, 2023, 9:30AMANS Nuclear Cafe

World Nuclear Energy Day takes place tomorrow, marking the 81st anniversary of the day in 1942 when Enrico Fermi and his team achieved the first controlled, self-sustaining nuclear chain reaction with Chicago Pile-1. It also is the anniversary of the first commercial nuclear reactor reaching criticality—at Shippingport, Pa., on December 2, 1957.
