The world faces an urgent need to decarbonize and expand clean energy systems. Earlier this year, the United States announced goals to achieve a 100 percent clean electricity grid by 2035 and net-zero emissions across the entire economy by 2050. Today, nuclear energy plants provide more than 50 percent of the United States’ carbon-free energy. Existing plants, along with the advanced technologies currently being developed and demonstrated, are crucial to the United States’ and the world’s clean energy future.

Technologies such as advanced non-light water reactors, which have higher operating temperatures than today’s light water reactors, will be vital to meeting economy-wide decarbonization goals. For example, process heat applications and chemical and synthetic fuel production require higher temperatures and currently rely on fossil fuels. Advanced reactors are the only carbon-free technologies that can provide the high temperatures these processes need.

Markey

At an otherwise congenial Nuclear Regulatory Commission oversight hearing held last week by the Senate Environment and Public Works Committee, Sen. Ed Markey (D., Mass.) made clear his strong disagreement with the agency’s November 3 decision to approve a proposed rule amending regulations for nuclear plants undergoing decommissioning.

“I fear the NRC now stands for Not Recognizing Concerns,” Markey said. “The NRC has decided that the best way to shield itself from criticism around the decommissioning process is to take itself out of the process. In the latest version of the proposed decommissioning rule, the NRC would have no ability to approve, no ability to change, no ability to deny plants’ decommissioning proposals, known as post-shutdown decommissioning activities reports. Its only job would be to acknowledge receipt of the report. Our independent nuclear safety regulator would serve as a glorified filing cabinet. Ceding the job of regulator to the nuclear industry itself is not a win for safety, communities, or for the energy sector.”

In a November letter to President Biden, ANS president Steven Nesbit and U.S. Nuclear Industry Council president and chief executive officer Bud Albright urged the president to proceed with nominations for the two open seats on the Nuclear Regulatory Commission. The letter stated, “The NRC operates best with a full complement of five qualified commissioners who have diverse and complementary backgrounds. . . . Unfortunately, the commission was last at full strength in January 2021, nearly a year ago.”

The track record for the successful decommissioning of nuclear facilities, both nationally and internationally, is impressive. In the United States, we have decommissioned many nuclear facilities, including complex materials sites, uranium recovery sites, research and test reactors, and nuclear power plants. To date, according to the Nuclear Regulatory Commission, 10 nuclear power plants have been completely decommissioned for unrestricted use, and another 26 power reactor sites are currently undergoing decommissioning through either SAFSTOR or DECON, following NRC regulatory requirements. In addition, the Nuclear Energy Institute identifies three nuclear power plants that were successfully decommissioned outside of NRC jurisdiction. While such a track record is impressive, the nuclear industry must be vigilant in focusing on lessons learned in order to continue to make gains in efficiency, cost savings, improved environmental stewardship, and enhanced stakeholder confidence. In reviewing the outcomes of decommissioning over many years, a number of key lessons learned have emerged.

A special issue of the ANS journal Nuclear Technology, published last month, observes the 75th anniversary of the Trinity experiment, the world’s first nuclear explosion, on July 16, 1945, near Alamogordo, N.M. The experiment was a first step toward the conclusion of the Manhattan Project and the end of World War II. The special issue, The Manhattan Project Nuclear Science and Technology Development at Los Alamos: A Special Issue of Nuclear Technology, was sponsored by Los Alamos National Laboratory and curated by Mark Chadwick.

Thanks to LANL, the 23 papers published in the issue are open access, which means that a subscription is not required to read this contribution to the history of science. The issue can be accessed on the journal’s platform, hosted by Taylor & Francis, publisher of ANS’s technical journals.

Hands

The U.K. government has confirmed its selection of the high-temperature gas-cooled reactor (HTGR) for Britain’s £170 million (about $236 million) Advanced Modular Reactor Demonstration Program.

Greg Hands, minister for energy, clean growth, and climate change, delivered the news on December 2 via a speech at the Nuclear Industry Association’s annual conference. “Following evaluation of responses received,” Hands said, “I’m pleased to announce today that we will focus on HTGRs as the technology choice for the program moving forward—with the ambition for this to lead to a demonstration by the early 2030s.”

NNL approved: “As we look to the future and the part we play as a scientific superpower, the U.K.’s unparalleled experience in gas-cooled technologies makes HTGRs the common-sense choice for pursuing advanced nuclear,” said Paul Howarth, chief executive officer at the United Kingdom’s National Nuclear Laboratory. “Following announcements already made on financing for the next stage of the Rolls-Royce SMR program and the proposed Nuclear Energy (Financing) Bill to make large-scale plants more achievable, the U.K. is primed once more to be a global leader in nuclear technologies—large, small, and advanced.”

Delbert

This year’s recipient of ANS’s Darlene Schmidt Science News Award is Caroline Delbert, a contributor to the Popular Mechanics magazine and website. The Schmidt Award seeks out journalists and science writers who demonstrate keen effort to report on the work of professionals in the field of nuclear science and technology. In her writing for Popular Mechanics, Delbert regularly covers nuclear, with a focus on advanced reactor designs, fusion energy, nuclear space technology, and non-energy applications of nuclear technology and radiation. This year alone she has published dozens of articles on those topics, and thanks to Popular Mechanics’ cross-publishing across Esquire, Men’s Health, MSN, Yahoo! News, and other platforms, Delbert’s dispatches on nuclear science and technology have reached a wider audience than a nuclear energy beat reporter at a financial website or trade publication could ever reach.

The Department of Energy’s National Nuclear Security Administration has issued a cooperative agreement worth $13 million to Niowave, of Lansing, Mich., to support the commercial production of molybdenum-99, a critical isotope used in more than 40,000 medical procedures in the United States each day, including the diagnosis of heart disease and cancer.

NuScale Power has signed a memorandum of understanding with Prodigy Clean Energy and Kinectrics to explore and inform the development of a regulatory framework to address the licensing and deployment of a marine power station (MPS). The MPS would integrate one to 12 NuScale power modules into a marine-based nuclear power plant system. The MPS would be shipyard-fabricated and marine-transported to its deployment location, where it would be moored in place in sheltered and protected waters at the shoreline. Prodigy is Canada’s first commercial marine nuclear power developer, specializing in integrating existing power reactors into stationary-deployed marine power plant structures. Kinectrics provides life-cycle management services to the electricity industry.

NuScale Power announced on December 2 that its small modular reactor plants will bear the name VOYGR. According to NuScale’s announcement, “The name VOYGR demonstrates that NuScale is changing the world by creating an energy source that is smarter, cleaner, safer, and cost-competitive.”

The Department of Energy issued a request for information (RFI) last week in response to President Biden’s February 24 executive order directing it to submit a report on supply chains for the energy sector industrial base within one year.

According to the order, the United States requires supply chains that are “resilient,” meaning “secure and diverse—facilitating greater domestic production, a range of supply, built-in redundancies, adequate stockpiles, safe and secure digital networks, and a world-class American manufacturing base and workforce.”

Nuclear power plants are not quick to change. So when four utilities announce they will make room for shiny new electrolyzers and consider tweaking their business model, that’s news.

Nuclear power plants can leverage the energy stored in some of the world’s heaviest elements to generate the lightest: hydrogen. That is not news, but it casts an aura of alchemy over straightforward engineering. Amid the hype, and the hope of significant federal funding, it’s worth acknowledging that hydrogen has an industrial history over 100 years old. In the potential matchup of hydrogen and nuclear power, it’s nuclear that would be the newcomer.

The President’s Special Session at the 2021 ANS Winter Meeting and Technology Expo, held Thursday morning, explored the current impasse over the management of spent nuclear fuel in the United States, with leaders from Congress and representatives from the Department of Energy and the U.S. Government Accountability Office sharing the work they are doing in an effort to break that impasse.

Unit B1 at Scotland’s two-unit Hunterston B nuclear power plant was taken off line for good on November 26 after nearly 46 years of operation. A 490-MWe advanced gas-cooled reactor, the unit entered commercial operation in June 1976. Its companion AGR, Unit B2, which entered operation in March 1977, is scheduled for retirement in January.

Ontario Power Generation (OPG) has selected GE Hitachi Nuclear Energy (GEH) as its technology partner for the Darlington nuclear new-build project. The companies will work to deploy GEH’s BWRX-300 small modular reactor at OPG’s Darlington nuclear plant, located in Clarington, Ontario.

AccApp'21, the 14th International Topical Meeting on Nuclear Applications of Accelerators, runs through December 4 and is being held as an embedded topical at the 2021 ANS Winter Meeting and Technology Expo in Washington, D.C. The meeting was to be held April 5-9, 2020, at the International Atomic Energy Agency’s headquarters in Vienna, Austria—and it was to be known as AccApp’20—but it was postponed because of COVID-19.

AccApp'21 is organized by ANS’s Accelerator Applications Division and cosponsored by Texas A&M University, the Department of Energy’s National Nuclear Security Administration, and the IAEA. The meeting’s focus is on the following areas:

• The production and use of accelerator-produced neutrons, photons, electrons, and other particles for scientific and industrial purposes.
• The production or destruction of radionuclides significant for energy, medicine, cultural heritage, or other endeavors.
• Safety and security applications.
• Medical imaging, diagnostics, and therapeutic treatment.

The newest generation of lithium-ion batteries now being developed uses thin-film, solid-state technology and could soon safely power cell phones, electric vehicles, laptops, and other devices. However, like all batteries, solid-state lithium-ion batteries have a drawback: Impedance—electrical resistance—can build up as batteries are discharged and recharged, limiting the flow of electric current.

The USS Enterprise (CVN-65), the world's first nuclear-powered aircraft carrier, has been named an ANS Nuclear Historic Landmark. The designation was officially recognized on December 1 during the ANS Winter Meeting in Washington, D.C.

The inscription on the plaque presented by ANS reads, “In recognition of the most advanced nuclear engineering technology of the 1950s and for her 51 years of service to our nation, the USS Enterprise (CVN-65) is designated as an ANS Nuclear Historic Landmark.”

The American Nuclear Society supports more than 50 college students each year through its Scholarship Program, awarding more than $140,000 annually. Applications for the 2022–2023 academic year are now available, and all ANS student members are encouraged to apply. Recipients will be awarded between $1,000 and $5,000, based on merit and financial need.

The 2021 ANS Winter Meeting and Technology Expo began this morning with a Opening Plenary Session chaired by Winter Meeting general chair Amir Vexler, president and chief executive officer of Orano USA. It was an opportunity to both celebrate achievements that are already building a “Nuclear Future” and to identify needs and challenges ahead.

Influential speakers from the U.S. Congress, the Department of Energy, and the Nuclear Energy Institute joined ANS president Steven Nesbit and ANS CEO/executive director Craig Piercy to explore key issues associated with the front end of the nuclear fuel cycle, including supply and demand for high-assay, low-enriched uranium (HALEU). They didn’t stop there, however. They took questions from an in-person and virtual audience that probed other requirements of a sustainable nuclear future, including fueling a human resources pipeline.
