Study: Microreactors show potential but face challenges

July 28, 2021, 9:30AMANS Nuclear Cafe

A recently released technical report from Idaho National Laboratory finds “significant potential” for deploying microreactors on a global scale, but also “significant challenges in achieving the technical capacities, meeting regulatory requirements and international accords, achieving competitive costs, and for gaining public acceptance.”

In the 147-page report, Global Market Analysis of Microreactors, authors David Shropshire from INL, Geoffrey Black from Boise State University, and Kathleen Araújo from the CAES Energy Policy Institute at Boise State assess the unique capabilities of microreactors and their potential deployment in specific global markets in the 2030-2050 timeframe.

New video stars nuclear: “The safest energy source known to man”

“You know what power source is more dangerous than nuclear? Literally, all of them. When you add up industrial accidents and the effects of pollution, nuclear is safer than coal or petroleum or natural gas.”

Report: Extreme weather is affecting nuclear power’s reliability

July 27, 2021, 7:10AMANS Nuclear Cafe

A new analysis shows that hurricanes and typhoons have become the leading causes of nuclear plant outages, at least in North America and South and East Asia, tech website Ars Technica reports in the article “Nuclear power’s reliability is dropping as extreme weather increases.” The analysis was written by Ali Ahmad, an energy policy and economics scholar at the Harvard Kennedy School, and was published in the July issue of the online journal Nature Energy.

Nuclear advocacy group presses for legislative action in Illinois

Czerwinski

Writing in today’s suburban Chicago Daily Herald, Madison Czerwinski, executive director of Campaign for a Green Nuclear Deal, warns of the damage to Illinois’s clean energy aspirations should the state’s policymakers fail to agree in time on legislation providing some form of aid to Exelon’s imperiled Byron and Dresden nuclear plants, both of which are slated for closure later this year. (And “in time” in this case means the next few weeks.)

Czerwinski notes in a guest column that despite the executive order signed by Gov. J.B. Pritzker in January 2019 committing Illinois to reducing greenhouse gas emissions consistent with the Paris climate agreement, electricity emissions in the state are up from last year by 36 percent—a number that will only grow in the event an acceptable bill is not forthcoming.

Group pans Spain’s call to exclude nuclear from EU taxonomy

Foro Nuclear, a Madrid-based association representing the interests of Spain’s nuclear sector, is not at all happy with its government’s involvement in a letter sent late last month to the European Commission calling for the exclusion of nuclear energy from the European Union taxonomy. (The taxonomy is a classification system establishing a list of environmentally sustainable economic activities for the EU.) Signing the letter were Spain’s minister for ecological transition and minister for the economy, as well as ministers from Austria, Denmark, Germany, and Luxembourg.

China moves closer to completion of world’s first thorium reactor

China is moving ahead with the development of an experimental reactor that would be the first of its kind in the world and “could prove key to the pursuit of clean and safe nuclear power,” according to an article in New Atlas.

Cultivating leadership behaviors in a post-pandemic energy sector

The nuclear community has been one of the safest and lowest-risk industries in the world, allowing it to compete in a crowded energy sector without compromise. This defining ethos is predicated on strong, emotionally safe cultures that have enabled the nuclear power sector to honestly and transparently learn from notable mistakes, such as the design flaws that led to the 2011 Fukushima Daiichi accident, resulting in a safer, more competitive industry.

Building nuclear plants faster and in a more affordable way

Finan

There is a lot of buzz around advanced reactors, and for good reason, according to Ashley Finan, director of the Department of Energy’s National Reactor Innovation Center (NRIC). In the article 3 Ways to Make Nuclear Power Plants Faster and More Affordable to Build, published earlier this month on the DOE’s website, Finan noted that advanced reactors promise to be cheaper to build and operate, offer enhanced versatility, and can help put the United States on a path to achieving net-zero emissions by 2050.

The key cost driver will be construction and project management, “areas that have plagued the industry for decades,” Finan noted.

“For advanced nuclear energy to realize its potential, we have to make it more affordable and scalable. Only then can it meaningfully contribute to our energy, security, and environmental imperatives,” she added.

Researchers share their cutting-edge work in AI for national security

July 15, 2021, 12:06PMANS Nuclear Cafe

Within the National Nuclear Security Administration, the Office of Defense Nuclear Nonproliferation Research and Development (DNN R&D) is leading efforts to drive advances in artificial intelligence and accelerate the adoption of AI-enabled technologies to solve nuclear nonproliferation and national security challenges.

The goal is to incorporate AI into advanced techniques for detecting nuclear weapons and materials. According to the NNSA, these detection capabilities support the nuclear nonproliferation and arms control goals of the United States, while also driving the development of new capabilities.

Nuclear Matters asks for half a minute of your time

July 14, 2021, 3:00PMANS Nuclear Cafe

Advocacy group Nuclear Matters is urging members of the nuclear community to send a pre-drafted letter to their representatives on Capitol Hill in support of companion bills H.R. 4024 and S. 2291, the Zero-Emission Nuclear Power Production Credit Act of 2021. The legislation calls for amending the Internal Revenue Code to establish a tax credit to help existing merchant nuclear plants continue operations.

Scientists use isotopic analysis to ID fraudulent truffles

Scientists from the Jozef Stefan Institute in Slovenia, with technical advice and analytical support from the International Atomic Energy Agency and the Food and Agriculture Organization of the United Nations, are studying the composition of truffles—a rare and expensive type of mushroom—in order to determine their origin and help detect fraud. Thanks to a database and the techniques developed, other laboratories worldwide can also test truffles, establish their geographical origin, and verify whether they are genuine.

News programmers’ hunger for stories about the aftermath of the earthquake and subsequent tsunami that caused three reactor meltdowns at Fukushima Daiichi in March 2011 shows no signs of abating.

The 1958 Ford Nucleon: An idea that’s still ahead of its time

A car capable of traveling 5,000 miles between fueling stops? Sounds impossible, right? It turns out that, yes, it was impossible. But that didn’t stop the Ford Motor Company in 1958 from envisioning a car—the Nucleon—powered by a small nuclear reactor. The Drive took a close look at the fantastical idea in a July 5 article, “Inside the Impossible Dream of the Nuclear-Powered 1958 Ford Nucleon.”
