Schönfeldt

In a recent episode of Azeem Azhar’s Exponential View, Troels Schönfeldt, chief executive officer of Seaborg Technologies, discussed his company’s reactor technology and other nuclear-related issues. Seaborg Technologies, which was founded in Copenhagen, Denmark, in 2014, is developing a compact molten salt reactor (CMSR) that it says is safe, significantly smaller, better for the environment, and inexpensive, even compared to fossil fuels, and can be manufactured quickly and deployed on barges to any location worldwide. The Exponential View is a podcast presented by the Harvard Business Review and hosted by Azhar, an entrepreneur and investor.

Different type of reactor: “We’re designing a fundamentally different type of nuclear reactor,” Schönfeldt said. “The powerful bullet points [are] that it cannot melt down or explode, it cannot release gases, it cannot be used for nuclear weapons. It could even burn nuclear waste, so we can get rid of some of the old waste stockpiles.”

Fitterling

Nuclear power from small modular reactors should be a central part of the chemical industry’s drive toward achieving carbon neutrality, according to Jim Fitterling, chairman and chief executive officer of Dow Inc. Fitterling’s comments, delivered at the 2022 International Petrochemical Conference, hosted by American Fuel & Petrochemical Manufacturers and held March 27–29 in San Antonio, Texas, were reported by Independent Commodity Intelligence Services (ICIS).

Beyond renewables: The ICIS report noted that more than 25 percent of Dow’s manufacturing sites are fully or partially powered by renewable energy sources, including wind, solar, and hydropower. Nevertheless, Fitterling said, “We need a broader and more realistic approach to feed our energy needs. Renewables are great, and we’re a tremendous supporter . . . but renewables alone are not the answer.” He added that renewable power generation would have to increase 90 times to equal the energy that is currently provided by hydrocarbons in the United States.

A recent article on a radio station website about an auxiliary feedwater (AFW) pump problem at the Diablo Canyon nuclear power plant led to information exchanges between a reporter, the American Nuclear Society, and nuclear advocates. The incident also involved a tweet by a member of the Union of Concerned Scientists.

This week for the #ThrowbackThursday post, we are again turning to the April 1984 issue of Nuclear News, which was highlighted in February when we looked at the start of the federal program to convert research reactors from the use of high-enriched uranium to low-enriched uranium. This week, however, we are reviewing the coverage presented in that issue about the five-year anniversary of the Three Mile Island-2 accident.

Musk

In a wide-ranging interview published by Business Insider on March 26, Elon Musk, chief executive officer of Tesla and SpaceX, repeatedly referred to efforts to shut down nuclear power plants as “crazy” and “madness.” Musk spoke with Mathias Döpfner, chief executive officer of Insider’s parent company, Axel Springer. Musk also discussed his views on the war in Ukraine, climate change, space travel, self-driving cars, humanoid robots, artificial intelligence, religion, and philanthropy.

Germany's mistakes: In discussing the Ukraine conflict and Western Europe’s dependence on Russian energy supplies, Döpfner referred to “strategic mistakes that Europe, particularly Germany, has made [such as] the dropout of nuclear energy in 2011.”

Musk responded, “It is very important that Germany will not shut down its nuclear power stations. I think this is extremely crazy.”

The Nuclear Innovation Alliance released a report on March 25 titled “ESG Frameworks and Advanced Nuclear Energy,” discussing how environmental, social, and governance (ESG) frameworks affect advanced nuclear energy technologies. The report, as described in an NIA press release, “includes potential actions the nuclear industry and financial community should consider to promote consistent analytical treatment of nuclear energy within ESG frameworks and efficient access to capital for nuclear investments.”

Need for consistent frameworks: Judi Greenwald, the NIA executive director, explained the need for consistent ESG frameworks, noting that “[n]uclear energy technologies are particularly affected by the inconsistent treatment of some frameworks regarding the ESG attributes of energy technologies. . . . As frameworks are standardized and embedded in policy, if their flaws are not addressed, advanced nuclear energy could be left at a disadvantage in terms of access to capital.”

On March 4, Russian forces set fire to an office building at Ukraine’s Zaporizhzhia nuclear power plant, raising fears about reactors being damaged. The attack stirred up memories of the Chernobyl accident in 1986, a reaction that longtime nuclear opponents are taking advantage of to rekindle their cause. However, the reactors operating in Ukraine today are profoundly different from the design used at Chernobyl, and are, by nature, difficult to damage.

Let’s set the record straight and explain the risks of nuclear power plants in war zones.

The trend of big-tech billionaires of Silicon Valley investing in next-generation nuclear energy startup companies continues. In a March 22 article on the Bloomberg website, Lizette Chapman, of the site’s venture capital group, writes that these investors view nuclear power as “a solution to both cutting carbon emissions and weaning the world off now-controversial Russian gas.”

“Many states have made carbon dioxide–reduction plans with no hope of success. But if they want to meet even a portion of those goals, they must put nuclear power back on the table.” So opined Tim Cavanaugh, senior editor at the Mackinac Center for Public Policy, in an essay published by The Hill on March 23.

The nonproliferation-related monitoring of nuclear reactor operations received a boost from a new study focusing on the use of seismic and acoustic data for such purposes, ScienceDaily reported last week. The study, conducted by investigators at Oak Ridge National Laboratory, was published March 9 in the journal Seismological Research Letters.

Findings regarding the corrosion resistance of two promising structural materials for fusion reactors were recently reported by ScienceDaily. The research, published in the April 1 issue of Corrosion Science, was conducted by a team led by Masatoshi Kondo of the Tokyo Institute of Technology. The researchers describe details of the high-temperature compatibility of the two materials with the liquid breeding blanket (BB) surrounding the reactor core.

The Department of Energy and Idaho National Laboratory announced this week that the sixth major core overhaul of the Advanced Test Reactor (ATR) is complete, after an 11-month outage that began in April 2021. The ATR was built as a key piece of mission support for U.S. Navy programs and first reached full power in 1969. Today it remains “the world’s largest, most powerful and flexible materials test reactor,” in the words of INL—quite a feat for a reactor that was planned over 60 years ago.

Smart Growth America—in partnership with the National Association of Development Organizations, the Center for Creative Land Recycling, and the Nuclear Decommissioning Collaborative—is hosting a webinar titled “Nuclear Communities Forum 2022” on Friday, April 1, from 11 a.m. to 3:15 p.m. (EDT).

According to a report published by the World Economic Forum, the top two skills that will help humans thrive in the fourth industrial revolution (i.e., the age of machine learning and artificial intelligence) are critical thinking and complex problem-solving.

My journey of discovery spans nearly four decades and four careers: the U.S. Navy, commercial nuclear power, the Nuclear Regulatory Commission, and consulting for the federal government. Along this journey, I was fortunate to gain a vast amount of experience in solving complex problems through the teachings of W. Edwards Deming, Joseph M. Juran, and others.

An article posted on the Interesting Engineering website on March 10 highlights a recent YouTube video that provides an overview of the advantages, current status, future possibilities, and practical challenges of small modular reactors, along with a look at the even smaller microreactors. The video is available on the “Undecided with Matt Ferrell” channel. Ferrell describes himself as “a UI/UX [user interface/user experience] designer by trade” and “a lifelong tech enthusiast.”

The election last week of Yoon Suk Yeol as president of South Korea has provided a big boost for that nation’s nuclear energy-related stocks. Yoon, of the conservative People Power Party, defeated Lee Jae-myung, of the incumbent liberal Democratic Party, on a pro-nuclear platform. As reported by marketwatch.com, Yoon has promised to “reinvigorate the nuclear-energy industry by reactivating suspended atomic power plants and resuming building new ones.”

The European Union could reduce imports of Russian natural gas by more than a third within a year through a combination of measures that would support energy security and affordability and would be consistent with the European Green Deal, according to a new report from the International Energy Agency.

“Nobody is under any illusions anymore,” said IEA executive director Fatih Birol on announcing the release of the report, A 10-Point Plan to Reduce the European Union’s Reliance on Russian Natural Gas. “Russia’s use of its natural gas resources as an economic and political weapon shows Europe needs to act quickly to be ready to face considerable uncertainty over Russian gas supplies next winter. . . . Europe needs to rapidly reduce the dominant role of Russia in its energy markets and ramp up the alternatives as quickly as possible.”

After offering a small shred of hope that it might be persuaded to keep its remaining power reactors in operation a bit longer to reduce its dependence on Russia for energy, Germany has opted to continue with its nuclear phaseout. The last three operating German reactors, Neckarwestheim-2, Isar-2, and Emsland, are slated for shutdown later this year.

Today’s #ThrowbackThursday post looks back at some of Nuclear News’s reporting on the Fukushima Daiichi accident, which was initiated 11 years ago tomorrow. The news reporting includes the initial coverage of the event from the pages of Nuclear News in April 2011 and the in-depth coverage of the 2011 ANS Annual Meeting, where special sessions focused on the accident.

The deadline for submitting comments on the Department of Energy’s request for information on using a consent-based approach to siting federal facilities for the interim storage of spent nuclear fuel is Friday, March 4.
