The Nuclear Regulatory Commission has withdrawn a proposed interpretation of its low-level radioactive waste regulations that would have permitted licensees to dispose of waste by transferring it to persons who hold specific NRC exemptions. “The proposal is being withdrawn based on the NRC staff’s assessment that the proposed changes may not benefit the regulatory framework for the disposal of low-level radioactive waste,” the NRC said in a December 17 Federal Register notice.

After releasing the proposed rule for public comment on March 6, 2020, the NRC received about 200 individual comment submissions and approximately 15,000 form letter submissions, the vast majority of which were in opposition to the proposed rule.

“We have strongly disputed the argument by various groups who misrepresented the proposal as deregulation of radioactive waste disposal,” NRC spokesperson David McIntyre told the Courthouse News Service. “This would not have changed anything, just made an existing case-by-case approval process more efficient.”

In another sign of U.S. interest in helping Poland develop a civil nuclear power program, the Export-Import Bank of the United States announced last week that it has signed a memorandum of understanding with the Polish government to promote U.S. energy investment in the Central European nation. (For an earlier agreement, see here.)

The MOU was signed in Warsaw on December 11 by Ex-Im president and chairman, Kimberly A. Reed, and Poland’s minister of climate and environment, Michał Kurtyka, during Reed’s three-day visit to Poland.

The Ex-Im: As the official export credit agency of the United States, Ex-Im provides loans, loan guarantees, and insurance to foreign customers purchasing U.S. exports.

The MOU particulars: The MOU calls for Ex-Im and Poland to “explore and identify potential opportunities for Ex-Im financing and to work together to promote business development opportunities related to strategic energy projects and programs,” according to Ex-Im’s announcement. The agreement includes, but is not limited to, support for projects in nuclear energy, in particular in support of strategic projects under Poland’s nuclear power program, low- and zero-emission technologies, clean energy innovation, and critical energy infrastructure, including cybersecurity solutions.

This article presents responses from various community members about those who inspired them—or the events or things that inspired them—to go on to have careers in nuclear.

There is an interesting mix of inspirators here, the most prominent being teachers who had lasting effects on their students. There are others who offered inspiration, too, including parents and other family members.

What all the respondents have in common is their inherent drive and love of science and technology to keep nuclear moving forward.

We would like to hear your story. Write in to let us know about it and we will share it within the pages of Nuclear News.

The Energy Sciences Coalition (ESC) issued a letter today to the incoming Biden administration’s transition team for the Department of Energy. The ESC is a broad-based group of organizations representing scientists, engineers, and mathematicians from universities, industry, and national laboratories that is committed to supporting and advancing the scientific research programs of the DOE and, in particular, the DOE Office of Science.

In an exclusive story published yesterday, the news website Politico reports that networks of the National Nuclear Security Administration and other federal entities have been hacked “as part of an extensive espionage operation.”

Citing officials familiar with the matter, the story says that network breaches have been identified at the NNSA’s Office of Secure Transportation (which is responsible for the transport of government-owned special nuclear materials), Los Alamos National Laboratory, Sandia National Laboratories, the Department of Energy’s Richland Field Office, and the Federal Energy Regulatory Commission.

According to the story, the hackers are believed to have gained access to the networks “by compromising the software company SolarWinds, which sells IT management products to hundreds of government and private-sector clients.”

A national strategy for the responsible and effective use of space nuclear power and propulsion (SNPP)—Space Policy Directive-6 (SPD-6)—was released by the White House on December 16 as a presidential memorandum.

Space nuclear systems include radioisotope power systems and nuclear reactors used for power, heating, or propulsion. Nuclear energy can produce more power at lower mass and volume compared to other energy sources and can shorten transit times for crewed and robotic spacecraft, thereby reducing radiation exposure in harsh space environments. SPD-6 establishes a road map for getting space nuclear systems into service and sets up high-level goals, principles, and federal agencies’ roles and responsibilities.

The levelized costs of electricity generation from low-carbon technologies, including nuclear, are dropping and are increasingly below that of conventional fossil fuel generation, concludes a new report from the International Energy Agency and the OECD Nuclear Energy Agency (NEA).

The 223-page report, Projected Costs of Generating Electricity—2020 Edition, the ninth such jointly produced analysis, includes plant-level cost data on power generation from nuclear, natural gas, coal, and a variety of renewable sources, including wind, solar, hydro, and biofuels. The report provides data from 243 plants in 24 countries.

Jack Steinberger, a Nobel Prize–winning scientist with a distinguished career in experimental physics, died December 12. He was 99.

Steinberger was most famous for his co-discovery of a new type of ghostlike particle called the muon neutrino—a breakthrough that earned him, Leon Lederman, and Melvin Schwartz the Nobel Prize in Physics in 1988. Steinberger studied the basic particles that make up the universe, and the elemental forces that govern their interactions, over a long scientific career that was jump-started by Enrico Fermi at the University of Chicago.

The Department of Energy’s National Nuclear Security Administration intends to prepare an environmental impact statement (EIS) evaluating alternatives for the safe disposal of 34 metric tons of surplus plutonium through its Surplus Plutonium Disposition Program (SPDP). The NNSA published in the December 16 Federal Register its intent to prepare the EIS, which will examine the agency’s preferred alternative, “dilute and dispose,” also known as “plutonium downblending,” and other identified alternatives for disposing of the material.

The NNSA is offering the public the opportunity to comment on the proposed scope of the EIS until February 1. In light of the COVID-19 health crisis, the agency will host an Internet- and phone-based virtual public scoping meeting in place of an in-person meeting. The date of the meeting will be provided in a future notice posted on the NNSA website.

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.”

The Department of Energy today announced $30 million in initial fiscal year 2020 funding—with the expectation of more over the next seven years—for five companies selected for risk reduction for future demonstration projects. The chosen reactor designs from Kairos Power, Westinghouse, BWX Technologies, Holtec, and Southern Company collectively represent a range of coolants, fuel forms, and sizes—from tiny microreactors to a molten salt reactor topping 1,000 MWe. They were selected for cost-shared partnerships under the Office of Nuclear Energy’s Advanced Reactor Demonstration Program (ARDP) through a funding opportunity announcement issued in May 2020.

“All of these projects will put the U.S. on an accelerated timeline to domestically and globally deploy advanced nuclear reactors that will enhance safety and be affordable to construct and operate,” said Energy Secretary Dan Brouillette. “Taking leadership in advanced technology is so important to the country’s future, because nuclear energy plays such a key role in our clean energy strategy.”

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.

You know the old saying that those who can, do, and those who can’t, teach? Well, I say anyone thinking that way should be kept far away from students!

In my time at Argonne National Laboratory and Idaho National Laboratory, I worked with incredible scientists and engineers doing cutting-edge research. Unfortunately, making progress in research is not always conducive to the education and training of those who haven’t yet gained the necessary expertise. And there is an interesting phenomenon that occurs the more one gains in education and experience: We tend to forget what we were like before, what it was like not to know everything we do now. More than one of my PhD colleagues at the national labs dismissed the education and outreach efforts that I pursued in my spare time: scouts, K-12 classroom visits, teacher workshops, science expos, etc., viewing any focus other than the truly technical as just “fluffy” and a waste of valuable time and effort.

We have dedicated this month’s edition of Nuclear News to university programs and their contributions in advancing the field of applied nuclear science and technology and readying the next generation of scientists and engineers.

Say what you want about the condition of the U.S. nuclear enterprise today, but there is no denying that our university-based programs in nuclear science and engineering are still the envy of the world. You can see it in the way these programs attract students and faculty from across the globe, and from their formative contributions to technologies, such as the NuScale power module and many of the advanced reactor designs being developed today.

The American Nuclear Society and Sociedad Nuclear Española (SNE) on December 10 signed a memorandum of cooperation (MOC) that creates a partnership between the two societies to cooperate in promoting the development of nuclear science and technology for peaceful purposes.

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.”

The Tennessee Valley Authority will load four new 3D-printed fuel assembly brackets next spring at its Browns Ferry nuclear power plant, in Athens, Alabama. The brackets will be the first of their kind loaded into a commercial reactor, according to the Department of Energy.

The components, also called channel fasteners, were manufactured at Oak Ridge National Laboratory, in Tennessee, in a joint project with TVA and its fuel supplier, Framatome, as part of the lab’s Transformational Challenge Reactor program. The program is designed to introduce new manufacturing techniques and approaches to industry partners in order to speed up the deployment of nuclear systems.

A 170-page energy white paper, Powering Our Net Zero Future, issued by the United Kingdom government on December 14 sets big goals for cleaning up the U.K.’s energy system. According to the U.K. government, the plan would create and support green energy jobs across England, Scotland, Wales and Northern Ireland and would keep electricity bills affordable as the U.K. transitions to net zero emissions by 2050.

The white paper notes that the U.K. will generate emission-free electricity by 2050 with a trajectory that will see "overwhelmingly decarbonized power in the 2030s. Low carbon electricity will be a key enabler of our transition to a net zero economy with demand expected to double due to transport and low carbon heat."

The white paper builds upon the U.K. prime minister’s 38-page Ten Point Plan for a Green Industrial Revolution, which was issued on November 18.

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.
