A Department of Energy report to the U.S. Congress shows that the reclassification of high-level radioactive waste could save more than $200 billion in treatment and disposal costs while allowing DOE sites to be cleaned up sooner—all still without jeopardizing public health and safety.

The report, Evaluation of Potential Opportunities to Classify Certain Defense Nuclear Waste from Reprocessing as Other than High-Level Radioactive Waste, identifies potential opportunities for the DOE to reduce risk to public and environment while completing its cleanup mission more efficiently and effectively. Those opportunities are based on the DOE’s 2019 interpretation of the statutory term HLW, which classifies waste based on its radiological characteristics rather than its origin.

Under the DOE’s interpretation of HLW, waste from the reprocessing of spent nuclear fuel may be determined to be non-HLW if the waste (1) does not exceed concentration limits for Class C low-level radioactive waste as set out in federal regulations and meets the performance objectives of a disposal facility; or (2) does not require disposal in a deep geologic repository and meets the performance objectives of a disposal facility as demonstrated through a performance assessment conducted in accordance with applicable requirements.

Adequate uranium resources exist to support the long-term, sustainable use of nuclear energy for low-carbon electricity generation, as well as for other applications, including hydrogen production. That assessment is contained in the latest (28th) edition of Uranium—Resources, Production and Demand, a global, biennial reference prepared jointly by the OECD Nuclear Energy Agency and the International Atomic Energy Agency.

The publication adds, however, that the impact of the COVID-19 pandemic and recent reductions in uranium production and exploration could affect available supplies, suggesting that timely investment in innovative mining and processing techniques would help assure that uranium resources are brought to market when needed.

Osterberg

An op-ed published in The Gazette, a Cedar Rapids, Iowa–based newspaper, laments the early closure of the Duane Arnold nuclear power plant in 2020. Author David Osterberg, a former Iowa state legislator, contrasts what happened in Iowa with Illinois and three other states, whose governments "decided that heading off climate damage and the loss of good union jobs was worth keeping nuclear plants there alive." The economic calculation in Duane Arnold's case treated its electricity the same as that from coal or natural gas plants. However, Osterberg states that “when it comes to global warming and local air pollution, they aren’t the same.”

Bulgaria has become the 34th member of the Paris-based OECD Nuclear Energy Agency (NEA). With its several decades of experience operating VVER units, Bulgaria will reinforce the NEA’s capacity to address matters related to pressurized water reactor technologies and their operational characteristics, according to the NEA on January 4.

In addition, the NEA said that it will support Bulgaria’s efforts in technical and policy areas, including work to address nuclear skills capacity building, the development and application of nuclear data and simulation codes, and issues related to radioactive waste management, decommissioning, and nuclear economics.

The Nuclear Regulatory Commission has announced the establishment of an Atomic Safety and Licensing Board to address a hearing request filed last month concerning Dominion Energy’s subsequent license renewal (SLR) application for the two reactors at its North Anna plant. The application, submitted in August of last year, was docketed by the NRC in October.

The contention: Filed by three anti-nuclear groups—Beyond Nuclear, the Sierra Club, and the Alliance for a Progressive Virginia—the 71-page hearing request argues that Dominion’s environmental report, submitted in support of its application, “fails to satisfy” the National Environmental Policy Act, as well as 10 CFR 51.53(c)(2) and 51.45(a), “because [the report] does not address the environmental impacts of operating North Anna Units 1 and 2 during the extended SLR term under the significant risk of an earthquake that exceeds the design basis for the reactors.”

Crane

Christopher Crane, president and chief executive officer of Exelon, wrote in a Chicago Sun-Times op-ed, “The failure of national energy markets to support clean energy will soon force the premature retirement of two of [Illinois’s] six zero-carbon nuclear plants, putting thousands of people out of work, raising energy costs, and taking us decades backward in the fight against climate change."

Crane urged Illinois policymakers to act quickly, as they face critical decisions about the future of energy that will affect the state’s environment, the economy, and the health of every family for years to come.

The rising influence of Russia and China in the development, construction, and deployment of civilian nuclear reactors around the globe raises significant geopolitical challenges for the United States, according to “Twenty-First Century U.S. Nuclear Power: A National Security Imperative,” a recent paper by two University of Georgia (UGA) researchers.

The U.K. government has agreed to delay until April 30 its decision regarding the issuance of a development consent order (DCO) for, the nuclear new-build project proposed for the island of Anglesey, off the northwest coast of Wales. (DCOs are required for large infrastructure projects in the United Kingdom to move forward.)

Happy New Year! I sincerely hope that each of you found time to refresh and rejuvenate over the holidays, or at least have fun. Many indicators suggest that 2021 will be a better year than 2020, including a growing understanding of COVID-19 and its impacts and the availability of a vaccine. So many have suffered from job loss or even loss of businesses in 2020. Even for those of us fortunate enough to be healthy, gainfully employed, and able to work from anywhere thanks to Zoom and its competitors, uncertainty is still a challenging aspect of the pandemic.

Craig Piercy

To you and all members of the nuclear professional community, Happy New Year! With the COVID-19 vaccine finally here, all indications point toward 2021 as the year we return to some semblance of normality. After all, this year has to be better than 2020, right?

Capt. Amy Bauernschmidt will assume command of USS Abraham Lincoln, the U.S. Navy announced last month. It marks the first time that a female commanding officer will lead the crew of one of the Navy’s 11 nuclear-powered aircraft carriers.

Bauernschmidt will take the Lincoln’s helm this summer, upon completion of the nuclear power, aviation, and leadership training required of aircraft carrier COs.

New research confirms the growing relevance of nuclear magnetic resonance technologies for the olive oil industry, according to the Olive Oil Times, based in Newport, R.I.

The latest Italian study, published in the scientific journal Foods, hints at the new opportunities emerging from the identification of the molecular footprint of extra virgin olive oil blends, which could be used to not only certify their contents but also to determine the transformational processes applied to the product.

Entergy Corporation and Holtec International have jointly submitted an application to the Nuclear Regulatory Commission for approval of the transfer of the licenses for the Palisades nuclear plant, in Covert, Mich., to Holtec, following the plant’s permanent shutdown and defueling in the spring of 2022.

The application, dated December 23, also requests approval of the license transfer of Entergy’s decommissioned Big Rock Point facility near Charlevoix, Mich., where only the independent spent fuel storage installation (ISFSI) remains.

Chairman Kristine Svinicki announced today that she intends to leave the Nuclear Regulatory Commission on January 20. She issued a statement in a press release from the NRC.

Chairman Svinicki has served as a commissioner under three administrations and is the longest serving member of the commission. She was first appointed to the commission by President Bush in 2007, was reappointed in 2012 by President Obama, and was designated chairman by President Donald J. Trump on January 23, 2017. Her term would have ended on June 30, 2022.

The European Commission’s current strategy for developing a hydrogen economy—part of its overall goal of achieving a climate-neutral European Union by 2050—needs to make more room for nuclear power. That’s according to a report published in December by the New Nuclear Watch Institute (NNWI), an industry-supported think tank based in the United Kingdom.

The 28-page report, On the Role of Nuclear Power in the Development of a European Hydrogen Economy, notes that the commission’s strategy, set out in last summer’s A Hydrogen Strategy for a Climate-Neutral Europe, sees the long-term future of the European hydrogen economy as one based on hydrogen production solely utilizing renewable power, thereby excluding nuclear from a lasting role in the market.

Workers in nuclear must be free to report potential problems without fear of retaliation. When it comes to issuing adverse actions, employers have a responsibility to ensure that protected activity rights are not infringed.

In this AI-designed layout for a boiling water reactor, fuel rods are ideally positioned around two fixed water rods to burn more efficiently. MIT researchers ran the equivalent of 36,000 simulations to find the optimal configurations. Colors correspond to varying amounts of uranium and gadolinium oxide in each rod.

Researchers at the Massachusetts Institute of Technology and Exelon show that by turning the nuclear fuel assembly design process into a game, an artificial intelligence system can be trained to generate dozens of optimal configurations that can make each fuel rod last about 5 percent longer, saving a typical power plant an estimated $3 million a year, the researchers report.

The AI system can also find optimal solutions faster than a human and can quickly modify designs in a safe, simulated environment. The results appear in the journal Nuclear Engineering and Design.
