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

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”

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.”

Japan-U.S. decommissioning workshop coming up

January 19, 2024, 12:00PMANS Nuclear Cafe

The Japan-U.S. Decommissioning Workshop Series continues on February 8–9 when its second forum meets to discuss the handling of low-level radioactive waste (LLW) generated during the decommissioning process and how improved LLW management can reduce risk.

Registration for the online event is required. The registration deadline is 2:00 a.m. (EST) on February 5.

Amidoximes aid in extraction of uranium from seawater

January 10, 2024, 7:01AMANS Nuclear Cafe

A new material based on amidoxime chemical groups may allow electrochemical extraction technology to extract uranium ions from seawater more efficiently than previous methods, according to a recent study published by the American Chemical Society’s ACS Central Science. If put into practical use, the new method, which was developed by researchers in China, could offer an environmentally sustainable source of fuel for nuclear power plants.

Bull market continues for uranium stocks

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.”

A new type of cold spray coating, made from the metal tantalum and applied to the plasma-facing steel walls of fusion reactors, could lead to efficient, compact fusion reactors that are easy to repair and maintain, according to a study recently published in the journal Physica Scripta. The study was led by scientists and engineers at the University of Wisconsin–Madison and involved researchers from South Korea, France, and Germany.

Coalition pushes Senate for $1.2 billion for the grid

January 4, 2024, 12:10PMANS Nuclear Cafe

A coalition of energy and grid industry associations led by the National Electrical Manufacturers Association (NEMA) today requested $1.2 billion in repurposed supplemental funding in upcoming negotiations on the Senate Energy and Water Development Appropriations Bill for Distribution Transformer and Grid Components.

Nuclear energy has watershed moment at COP28

What happened at COP28, the annual United Nations climate event held this year in Dubai, was the greatest outpouring of global support for nuclear power the world has seen since the thunderous reception to Eisenhower’s Atoms for Peace call exactly 70 years ago. For the first time, nuclear energy was specifically mentioned in the closing statement of a COP event as one possible way to combat climate change.

ENEC-EPRI report describes decarbonization with nuclear energy

December 21, 2023, 7:01AMANS Nuclear Cafe

A new report from the Emirates Nuclear Energy Corporation (ENEC) and the Electric Power Research Institute (EPRI) describes the use of nuclear energy to decarbonize some activities normally powered by oil and gas.

Decarbonization Strategies for Upstream Oil and Gas Operations with Advanced Nuclear Technologies, prepared by the Massachusetts Institute of Technology under contract to EPRI, was intended to “inform broader discussions around decarbonization [oil and gas] operations” at COP28, held in Dubai, United Arab Emirates, from November 30 to December 12.

Granholm visits Clinch River Site to show support for SMRs

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.

So far this year, Savannah River Nuclear Solutions Supply Chain Management (SCM) apprenticeship program has transitioned 12 new graduates to its team. According to SRNS, the apprentices and interns were attracted to the training program through new recruiting connections that SRNS has established with universities and colleges in the Aiken, S.C., area. The SCM program, which is designed to transition participants into full-time positions at the Savannah River Site, has recently increased internal incentives.

Argonne physicist leads research on nuclear clock

Shvyd’ko

A major step toward the creation of the most precise atomic clock ever—with an accuracy of one second in 300 billion years—was recently reported in Nature by an international team of researchers working at the European X-Ray Free-Electron Laser (XFEL) facility. The researchers, led by senior physicist Yuri Shvyd’ko of Argonne National Laboratory, created a pulse generator based on the element scandium that demonstrated an extremely narrow resonance frequency capable of maintaining unprecedented time accuracy.

Atomic and nuclear clocks: In atomic clocks, the electrons in the atomic shells of certain elements—most commonly cesium—are raised to higher energy levels with microwave radiation. The microwave frequency is tuned to maximize the radiation absorption within a particular resonance range.
