In a program sponsored by the National Nuclear Security Administration’s Office of Defense Nuclear Nonproliferation, teams of engineering students from Washington State University designed, built, and delivered prototype equipment to address challenges encountered by Pacific Northwest National Laboratory staff in research on nuclear safeguards.

As reported on March 11 by the NNSA, two teams of WSU students presented their projects to PNNL staff during an online meeting in December 2020. One team created physical training aids for safeguards courses to demonstrate two methods of nuclear fuel reprocessing. The other team developed an enrichment monitor mounting bracket that the International Atomic Energy Agency could use to help monitor uranium hexafluoride gas in enrichment facilities.

Join the American Nuclear Society on Friday, March 26, from 1 p.m. to 2 p.m. (EDT) to hear perspectives on the future of nuclear energy offered by individuals who have played a significant role in framing the United States’ nuclear energy policies of the past, present, and future.

Shellenberger

In testimony last Thursday before the Senate Committee on Energy and Natural Resources, Michael Shellenberger, founder and president of Environmental Progress, called for maintaining the current U.S. fleet of nuclear power reactors. He argued that the premature closure of nuclear plants threatens the reliability, resiliency, and affordability of the nation’s electricity supply, as well as its ability to reduce carbon emissions.

Without state or federal action, 12 reactors will close by 2025, resulting in the loss of 10.5 GW of “highly reliable, low-cost, and low-carbon power,” Shellenberger noted in his written statement. He added, “If those nuclear plants are lost, grids may suffer from energy shortages during future heat waves or cold snaps.”

Advanced reactor development and testing could benefit from a Pacific Northwest National Laboratory innovation that combines remote, real-time monitoring of gaseous fission by-products with a software package designed with plant operators in mind, according to an article published online earlier this month.

The basics: “Real-time monitoring is a valuable tool, particularly in the development of next-generation reactors,” said Amanda Lines, a PNNL chemist. “This can help designers more efficiently and effectively design and test flow loops, mechanisms, or processes. Also, when they ultimately deploy their reactor systems, this gives operators a tool to better understand and control those processes.”

COVID-19 has touched our lives in many ways, affecting work, school, and homelife. The Diversity and Inclusion in ANS Committee is holding a free webinar, "Coping with COVID: The Pandemic and the Nuclear Community," on Tuesday, March 23, from 1:00 p.m. to 2:30 p.m. (EDT).

Panelists will discuss how the nuclear community is responding to the pandemic, what more can be done, what support resources are available, and what the future looks like.

Registration is required for the webinar.

Researchers at Texas A&M University have recently demonstrated the superior performance of a new oxide-dispersion-strengthened (ODS) alloy developed for use in both fission and fusion reactors.

Lin Shao, a professor in the university’s Department of Nuclear Engineering and an ANS member, worked alongside research scientists at Los Alamos National Laboratory and Hokkaido University to create the next generation of high-performance ODS alloys. So far, the researchers reported, the alloys are some of the strongest and best-developed metals in the field.

Details of the project were published in the February 2021 issue of the Journal of Nuclear Materials.

A new technical report from Montreal-based SNC-Lavalin finds Canada’s stated goal of net-zero carbon emissions by 2050 to be achievable but stresses the importance of immediate action and investment in all forms of low-carbon energy production, including nuclear, hydro, renewables, carbon capture and storage, and hydrogen.

According to the 100-page document, Engineering Net Zero, Canada needs to triple its power production levels over the next 30 years, as forecasts show demand growing from 500 TWh to 1,500 TWh.

A 28-page executive summary of the report is available online.

As long as commercial nuclear power plants operate anywhere in the world, the authors of an article published this week on The Conversation believe it is critical for all nations to learn from what happened at Fukushima and continue doubling down on nuclear safety. But the authors, Kiyoshi Kurokawa and Najmedin Meshkati, say that a decade after the accident, the nuclear industry has yet to fully to address safety concerns that Fukushima exposed; the authors assign an “incomplete” grade to global nuclear safety.

In their article, Kurokawa and Meshkati write that the most urgent priority is developing tough, system-oriented nuclear safety standards, strong safety cultures, and much closer cooperation between countries and their independent regulators. They also believe that the International Atomic Energy Agency should urge its member states to find a balance between national sovereignty and international responsibility when it comes to operating nuclear power reactors in their territories.

In an article published on March 5, Axios reviews the ways the world’s maritime companies are trying to decarbonize. The maritime industry, “from ferries to freighters—is trying to navigate a once-in-a-century transition away from fossil fuels to new, cleaner means of propulsion,” the article explains.

Emissions from shipping: The article notes that the world’s economy relies on international shipping, with more than 90 percent of global trade traveling via maritime vessels. The issue, though, is that “the vessels burn about 4 million barrels of oil a day, accounting for almost 3 percent of the world’s carbon emissions.” The article then cites a United Nations report from 2018 that sets greenhouse gas reduction targets of 50 percent by 2050 compared to 2008 levels.

Nuclear power is an important component in the fight against climate change, but independent regulation is needed to gain the public’s---and governments'---trust, according to a March 6 article in The Economist, “Nuclear power must be well regulated, not ditched.”

The article reviews the negative effect that the Fukushima Daiichi accident had on the worldwide nuclear industry following the earthquake and tsunami in March 2011. Japan’s direct economic cost, estimated at more than $200 billion, was larger than that of any other natural disaster the world has seen, according to the article.

Granholm

Energy Secretary Jennifer Granholm on Wednesday during the CERAWeek energy conference commented that Texas should look beyond its borders to join other grids following last month's winter storm that left millions without power, according to an article from The Hill.

“It would be great for Texas to consider connecting ... to its neighbors,” she said. “I understand the go-it-alone sort of ethos, but there’s also an ethos of helping your neighbor too and I think connecting could benefit Texas in times of emergency, but it could also benefit Texas and the rest of the country in good times when Texas is generating all sorts of clean energy."

An aerial seeding project on the Hanford Site’s Gable Mountain will help restore lost habitat following a wildland fire in June of last year, according a March 3 announcement from the Department of Energy’s Richland Operations Office (RL). The wildfire burned more than 5,500 acres on the mountain at Hanford, in Washington state.

Outgoing DOE contractor Mission Support Alliance coordinated the effort to drop 75,000 pounds of native grass and shrub seed from a helicopter during the rainy winter season. The project will continue under the new contractor, Hanford Mission Integration Solutions. Biologists expect the seeds to germinate by spring.

“Remediating environmental damage from the Gable Mountain fire is a priority, and the use of harvested native seeds will offer the best chance at future restoration of this critical habitat,” said So Yon Bedlington, RL program manager.

Manchin

Speaking at a U.S. Senate committee meeting this week, Sen. Joe Manchin (D., W.V.) said that continuing support for nuclear energy would be essential in meeting the country’s goals of reducing the emissions that fuel climate change, according to the Politico Pro newsletter.

Details: Manchin, who heads the U.S. Senate Energy and Natural Resources Committee, was highly critical of anyone suggesting that climate change can be addressed without nuclear energy being in the mix.

An article published by The New Yorker profiles how Heather Hoff and Kristin Zaitz went from environmentalists who were skeptical, and even distrusting, of nuclear power to advocates for the much-maligned power source.

Astatine-211 recovery from bismuth metal using a chromatography system. Unlike bismuth, astatine-211 forms chemical bonds with ketones.

In a recent study, Texas A&M University researchers have described a new process to purify astatine-211, a promising radioactive isotope for targeted cancer treatment. Unlike other elaborate purification methods, their technique can extract astatine-211 from bismuth in minutes rather than hours, which can greatly reduce the time between production and delivery to the patient.

“Astatine-211 is currently under evaluation as a cancer therapeutic in clinical trials. But the problem is that the supply chain for this element is very limited because only a few places worldwide can make it,” said Jonathan Burns, research scientist in the Texas A&M Engineering Experiment Station’s Nuclear Engineering and Science Center. “Texas A&M University is one of a handful of places in the world that can make astatine-211, and we have delineated a rapid astatine-211 separation process that increases the usable quantity of this isotope for research and therapeutic purposes.”

The researchers added that this separation method will bring Texas A&M one step closer to being able to provide astatine-211 for distribution through the Department of Energy’s Isotope Program’s National Isotope Development Center as part of the University Isotope Network.

Details on the chemical reaction to purify astatine-211 are in the journal Separation and Purification Technology.

Gates

Bill Gates is making the media rounds to promote his new book, How to Avoid a Climate Disaster: The Solutions We Have and the Breakthroughs We Need, which was released on Tuesday. Along the way, he’s been touting nuclear energy as part of his master plan for battling climate change.

60 Minutes: Gates kicked off the week with an appearance on 60 Minutes on Sunday. During the nearly 15-minute segment with correspondent Anderson Cooper, Gates discussed TerraPower, the company he founded in 2006 that is dedicated to nuclear innovation. “Nuclear power can be done in a way that none of those failures of the past would recur, because just the physics of how it's built,” Gates said, referring to TerraPower’s Natrium reactor. “I admit, convincing people of that will be almost as hard as actually building it. But since it may be necessary to avoid climate change, we shouldn't give up.”

The Bulletin of the Atomic Scientists published on February 16 an article questioning the logic of completing construction on Brazil’s long-dormant Angra-3 nuclear power plant.

The Brazilian government in 2019 decided to resume construction of Angra-3, after 35 years on hold. The article, Brazil’s Angra 3 nuclear reactor: A political undertaking, not a common good, states that “the work was supposed to restart last year, with the reactor entering commercial service by late 2026, but COVID-19 and the quest for private partners to invest in the project have pushed back the schedule.”

Vice News has published a video on YouTube that follows two farmers from the Fukushima Prefecture, Noboru Saito and Koji Furuyama. Saito, who grows many different crops on his farm, says that the rice grown in the area is consistently rated as the best. Furuyama specializes in peaches and explains his strategy to deal with the stigma of selling fruit from Fukushima: grow the best peaches in the world.
