The January/February 2021 issue of Popular Mechanics hit subscriber mailboxes this week with a stark cover image of a single small reactor under the headline, “Tiny nuclear reactors are about to revolutionize American energy.” The story looks at advanced reactors as a pivotal step to “redeem nuclear’s stature in American energy.”

A good primer: The article does a good job introducing the casual reader to the idea that “bigger is no longer better” and that the future of nuclear power in the United States will most likely be “a combination of traditional large plants and smaller, safer megawatt reactors.”

Advanced reactors, including small modular reactors, show that nuclear is no longer a one-size-fits-all operation, the article notes. The industry now “is all about personalization,” says Ken Canavan, Westinghouse’s chief technical officer, who is quoted in the article. The capacity and scalability of SMRs “is just irreplaceable,” he adds.

The article explains that SMRs, microreactors, and other advanced reactor designs will be able to bring reliable, carbon-free power to small or remote locations, replacing fossil fuel power plants and supplementing the “resource-sucking downtimes left by renewables.”

Granholm

President-elect Joe Biden will pick former Michigan governor Jennifer Granholm to run the Department of Energy, Politico reported on December 15. The DOE is expected to play a key role in helping develop the technologies needed to fulfill Biden’s pledge to move the country off fossil fuels.

A video posted to Twitter by Vice News discusses the prospect of advanced reactors being an important mix of carbon-free power production in the United States. Hosted by Gelareh Darabi, an award-winning Canadian-British-Iranian journalist and documentary filmmaker, the video provides quick and easy statistics for the general audience and pulls from social media influencer I_sodope. It also includes comments from nuclear experts.

The Bellona news site is reporting that Rosatom is marketing its floating nuclear power plants to foreign countries. The news item noted on December 14 that Russia’s Tass newswire had published the information, citing government statements. Rosatom is Russia’s state nuclear corporation.

“Rosatom has made proposals for the installation of floating units to a number of foreign countries,” Yury Trutnev, a deputy prime minister and presidential representative to Russia’s Far Eastern Federal District, said earlier this month, according to Tass. “It’s clear that one unit is not enough for us to sell such modules. Their future replication would open a possibility for Russia to open a market niche where there currently is no one.”

Burgess

The U.S. Congress has failed to uphold its promise to fully fund Yucca Mountain, in Nevada, as a permanent repository for spent nuclear fuel, Rep. Michael C. Burgess (R., Texas) writes in an op-ed article published on December 8 in the Dallas Morning News.

More than three decades after passing the Nuclear Waste Policy Act, Congress has yet to fully fund the Yucca Mountain Project. Burgess points out that while some countries have found success with reprocessing spent fuels, the fission process will always produce some amount of material that must be safely disposed, making it necessary to find a permanent solution.

Chesney

An Illinois lawmaker is hopeful that legislation is coming in the state that would benefit nuclear power plants. “I believe we’re going to have an incentive program that will be in partisan legislation,” said Andrew Chesney, Illinois state representative for the 89th District.

Nuclear decommissioning projects can benefit from the lessons learned in the fossil fuel industry, according to a December 8 Reuters Events post that draws heavily from an article published in the ANS magazine Radwaste Solutions.

Reuters reporter Paul Day interviewed the authors of “Tapping Nonnuclear Knowledge,” which appeared in the Fall 2020 issue of RS and examines research being done on cross-sector learning between nuclear and oil and gas decommissioning projects, particularly the mega projects of decommissioning nuclear power plants and offshore oil rigs.

In an article published by the Canadian Broadcasting Corporation on December 7, politicians representing New Brunswick, Canada, debate the benefits and potential risks of investing in small modular reactor development. Two major parties in the province support SMR development, while the Green Party sees “danger signs.”

A renewed U.S. interest in advanced nuclear technology is making headlines around the world. Growing energy needs and an increased desire to limit carbon emissions are driving a flurry of activity among education institutions, national laboratories, and private companies. New nuclear technologies are rapidly maturing toward commercialization with the aim of deploying a new generation of advanced reactors. These advanced nuclear energy systems have the potential to provide cost-effective, carbon-free energy; create new jobs; and expand nuclear energy’s outputs beyond electricity generation alone.

“DOE and U.S. industry are extremely well-equipped to develop and demonstrate nuclear reactors with the requisite sense of urgency, which is important not only to our economy, but to our environment, because nuclear energy is clean energy,” Rita Baranwal, assistant secretary for Nuclear Energy, recently noted in a Department of Energy news release.

The DOE anticipates significant global demand for advanced reactors, and with support from Congress, intends to invest $3.2 billion over the next seven years in the new Advanced Reactor Demonstration Program (ARDP). The initial funding opportunity was announced in May 2020. The call specified the need for reactor technologies that improve on the safety, security, economics and/or environmental impact of currently operating reactor designs. The goal of the program is to maintain the nation’s leadership in the global nuclear energy industry through the successful research, design, and deployment of advanced reactors in the United States and international marketplaces.

The ARDP will provide funds for three phases of public-private technology development partnerships over the next decade and a half:

1. Advanced Reactor Demonstrations: The initial $160 million funding allocation, announced in October 2020, will support two companies that can license, construct, and operate an advanced reactor design in the next five to seven years.
2. Risk Reduction for Future Demonstration: The second phase of funding availability will support an additional two to five reactor designs that could be commercialized approximately five years after the Advanced Reactor Demonstrations. Awards are expected to be announced by the end of 2020.
3. Advanced Reactor Concepts-20 (ARC-20): The third pathway to meet the advanced reactor demonstration goals will support up to two less mature reactor designs that will take a further five years to develop beyond the Risk Reduction phase.

Half of the world’s energy goes into producing heat for industries that make steel, cement, glass, and chemicals, according to the Bloomberg article, Atomic Heat in Small Packages Gives Big Industry a Climate Option. That heat, sometimes reaching temperatures above 1,000 ^oC, accounts for two-fifths of the world’s carbon dioxide emissions.

The Atlantic Council’s Global Energy Center has issued a report, Japan’s Nuclear Reactor Fleet: The Geopolitical and Climate Implications of Accelerated Decommissioning, contending that Japan’s reaction to the 2011 Fukushima Daiichi nuclear accident has led to an increased dependence on carbon-emitting energy sources that ultimately undermine the country’s recently announced climate goal of achieving net-zero emissions by 2050.

Recommendations: Released just a few months prior to the 10-year anniversary of the accident on March 11, 2011, the report recommends that Japan:

• Use its existing nuclear fleet in the near and long term to 2050,
• remain involved in global civil nuclear trade,
• develop a role for advanced nuclear technologies, including small modular reactors, which it should deploy as soon as feasible,
• rebuild its nuclear energy workforce and public trust in nuclear power, and
• regain its leadership position in the climate battle.

The International Atomic Energy Agency has awarded fellowships to the first group of 100 female students from around the world under a new initiative to help close the gender gap in nuclear science and technology.

The Marie Sklodowska-Curie Fellowship Program, named after the pioneering physicist, was launched by IAEA Director General Rafael Mariano Grossi in March to support women pursuing nuclear-related careers.

The United Kingdom’s Department for Business, Energy and Industrial Strategy has asked local governments to submit bids to host the Spherical Tokamak for Energy Production project, or STEP, according to an article published by Bloomberg on December 1.

The STEP plant will be developed by the U.K. Atomic Energy Authority, which says that construction could begin as soon as 2032, with operations by 2040, and “will prove that fusion is not a far-off dream.”

Piercy

The scheduled premature shutdown of Indian Point-3 will all but guarantee a massive increase in fossil fuel use, according to an op-ed written by American Nuclear Society President Mary Lou Dunzik-Gougar and Executive Director/CEO Craig Piercy that was published in the New York Daily News on November 30.

Indian Point-3 is slated to be shut down in April 2021, four years before its operating license expires.

I should state up front that I am not an expert in matters of dealing with communicable diseases, although like most of us, I am much more knowledgeable in the area than I was a year ago.

In COVID-19, the world is dealing with a disease that has killed more than a quarter-million Americans in less than a year and, when all is said and done, will have led to the deaths of millions worldwide. Beyond the immediate fatalities, there are the aftereffects on the health of survivors and immensely adverse economic, psychological, and social impacts on the human race. It doesn’t even stop there—other species on our planet are similarly impacted. It’s not quite Stephen King’s The Stand or a zombie apocalypse, but “it could be worse” is cold comfort when you look at the reality of the situation. Like everyone, I have experienced indirectly the effects of COVID-19. I have lost friends and colleagues to the disease, but fortunately, so far, no close family members.

Baranwal

In a blog post to the Department of Energy’s website on November 23, Rita Baranwal, assistant secretary for the Office of Nuclear Energy, commended recent virtual lesson projects from the Office of Nuclear Energy and the Nuclear Energy Tribal Working Group to increase STEM opportunities for Native American tribes.

The spotlighted lesson discussed in the article focused on a 3D-printed clip that turns a smartphone or tablet into a microscope with the ability to magnify items by 100 times. The Office of Nuclear Energy shipped nearly 1,000 of these microscope clips to students across the country, many of them going to U.S. tribal communities.

An MIT-led team found that the formulas describing how atoms behave in a gas can be generalized to predict how protons and neutrons interact at close range. Image: Collage by MIT News. Neutron star image: X-ray (NASA/CXC/ESO/F.Vogt et al); Optical (ESO/VLT/MUSE & NASA/STScI)

In an MIT News article playfully titled “No matter the size of a nuclear party, some protons and neutrons will always pair up and dance,” author Jennifer Chu explains that findings on the interactions of protons and neutrons recently published in the journal Nature Physics show that the nucleons may behave like atoms in a gas.

A Massachusetts Institute of Technology–led team simulated the behavior of nucleons in several types of atomic nuclei using supercomputers at Los Alamos National Laboratory and Argonne National Laboratory. The team investigated a range of nuclear interaction models and found that formulas describing a concept known as contact formalism can be generalized to predict how protons and neutrons interact at close range.

Majumdar

Arun Majumdar, a professor of mechanical engineering at Stanford University and former vice president for energy at Google, is a leading contender for secretary of energy in a Biden administration, according to a November 12 Bloomberg story.

Chosen on November 10 to lead Biden’s Department of Energy transition team, Majumdar was also the first director of the Advanced Research Projects Agency-–Energy (ARPA-E), serving in that role from 2009 to 2012. Bloomberg quotes Jeff Navin, director of external affairs at TerraPower, as saying, “He had as good relationships with Republicans as he did with Democrats as the first director of ARPA-E, and he took the time to get to know key legislators personally.”

Although a much-discussed October 12 story from Bloomberg headlined “Exelon Weighs Shedding Nuclear Plants, Other Non-Utility Assets” went unconfirmed, a new report from Greentech Media says that confirmation has now taken place.
