New research into the dynamics and structure of high-temperature liquid uranium trichloride (UCl3) salt—a potential fuel for molten salt reactors—has been published in the Journal of the American Chemical Society. A recent news release from Oak Ridge National Laboratory describes how researchers from ORNL, Argonne National Laboratory, and the University of South Carolina used ORNL’s Spallation Neutron Source (SNS) to document the unique chemistry of liquid UCl3 “for the first time.”

Dust: Trapped by a laser or threatening ITER, it’s making headlines

Start talking about dust in a vacuum, and some people will think of household chores. But dust has featured in recent nuclear science and engineering headlines in curious ways: ITER is deploying oversized dust covers inspired by space satellites in the south of France, while at Yale University, researchers have watched every move of a dust-sized particle levitating in a laser beam for telltale twitches that indicate radioactive decay.

Kilindini Harbor in Mombasa, Kenya, is East Africas largest international seaport. But rapid development of the Kenyan coastal zone is changing sediment distribution and dispersal patterns in the region, and shifting sediment poses safety and efficiency risks to ships in the harbor. With help from the International Atomic Energy Agency, a team of researchers from Kenya and South Africa has deployed a unique system to measure natural radionuclides in beach and aquatic sediments and map sediment transportation in the region. The IAEA described the mission in a photo essay published August 21.

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.

The U.S. Department of Energy is constructing the Electron-Ion Collider (EIC) at Brookhaven National Laboratory to explore the boundaries of nuclear physics—both for the sake of science and to support diverse applications, including in nuclear medicine, radiation safety, and nuclear energy. The project, already supported by international collaborators in 40 countries, just secured a significant commitment from the United Kingdom.

The IAEA celebrates International Women's Day

The International Atomic Energy Agency and the Food and Agriculture Organization of the United Nations launched Atoms4Food on October 18 at the 2023 World Food Forum in Rome as a flagship initiative to help boost food security and tackle growing hunger around the world. Atoms4Food will support countries as they apply nuclear techniques to boost agricultural productivity, reduce food losses, ensure food safety, improve nutrition, and adapt to the challenges of climate change.

2023 ANS Winter Conference and Expo coming to Washington, D.C.

October 6, 2023, 7:00AMANS News

The American Nuclear Society’s largest and most anticipated annual event, the Winter Conference and Expo, will take place November 12–15 at the Washington Hilton in Washington, D.C.

This year’s theme is “Maintaining the Momentum,” which suits nuclear energy’s current moment in the spotlight. In the last few years, public investment in both new and existing nuclear technology has expanded alongside a rise in public support and acceptance. Now is the perfect time for the nuclear industry to seize this momentum by coming together to maintain current nuclear plants, expand the nuclear workforce, strengthen supply chains and infrastructure, increase public and private sector investments, and continue to advocate for the benefits of nuclear power.

Fusion is prioritized in net-zero R&D initiative and IRA funds, but fission factors in too

Just days before COP27 and the U.S. midterm elections, the White House announced $1.55 billion in Inflation Reduction Act (IRA) funding for national laboratories and the launch of a Net-Zero Game Changers Initiative based on a new report, U.S. Innovation to Meet 2050 Climate Goals. Out of 37 research and development opportunities identified, fusion energy was selected as one of just five near-term priorities for the new cross-agency initiative. Together, the announcements signal policy and infrastructure support for fusion energy—the biggest chunk of Department of Energy Office of Science (DOE-SC) IRA funding went to ITER, via Oak Ridge National Laboratory—and for advanced nuclear technologies to power the grid and provide process heat to hard-to-decarbonize industrial sectors.

November 7: The unofficial day of women in nuclear science?

Marie Curie was born in Warsaw in 1867 on this day, 155 years ago. Exactly 11 years later, in 1878, Lise Meitner was born in Vienna. November 7 is also the date when, in 1911, the Swedish Royal Academy of Science decided to award Curie a second Nobel Prize for her 1898 discovery of the elements radium and polonium (coincidentally, her 44th birthday). Curie, who at age 36 had shared the 1903 Nobel Prize in Physics with her husband, Pierre Curie, and Henri Becquerel, later accepted the chemistry prize on December 10, 1911. She remains to this day the only person—man or woman—to receive two Nobel Prizes in two different fields of science. (Linus Pauling was also awarded Nobel Prizes in two categories: chemistry and peace.) On this unofficial day of women in nuclear science, let’s take a moment to acknowledge the fundamental discoveries of both Curie and Meitner.

The International Atomic Energy Agency convened a workshop last week to explore how nuclear techniques backed by the IAEA’s Zoonotic Disease Integrated Action (ZODIAC) initiative could be used to avoid outbreaks of monkeypox and Lassa fever. The meeting, held in Vienna, Austria, on the sidelines of the IAEA Board of Governors meeting, was organized to assist countries in using nuclear and related techniques to detect, mitigate, and understand the behavior of the viruses.

“It is important that we are reacting quickly, as things happen. I am happy that concrete work is being carried out on something before it becomes a very difficult problem,” said IAEA director general Rafael Mariano Grossi as he opened the one-day summit.

Progress being made on Nuclear Grand Challenges

January 24, 2022, 9:29AMNuclear NewsAndrew C. Klein

Early in my year as ANS vice president/president-elect, I was determined to try to find a project that the entire ANS community could rally behind and could be completed during my year as ANS president. I was looking for something that would provide community-identified focus areas for future activities and that would mobilize, energize, and inspire ANS members during that year and in the years ahead.

Episode 22 of RadioNuclear is now available. In this episode, we discuss the recent miniseries "Chernobyl", which recently concluded on HBO. We debunk some of the more egregious articles written in the wake of the show (see links to these articles below). We also discuss good ways to engage with individuals who are captivated with the show, and not necessarily familiar with nuclear technology.
