The Department of Energy announced September 13 that it would spend up to $10 million in a bid to settle the question of whether low-energy nuclear reactions (LENR)—historically known as “cold fusion”—could ever become a carbon-free energy source. The funding is part of an Advanced Research Projects Agency–Energy (ARPA-E) LENR Exploratory Topic designed to “encourage the submission of the most innovative and unconventional ideas in energy technology.”

Atkins Nuclear Secured Holding Corporation, a member of the SNC-Lavalin Group, celebrated the start of construction on its new, $20 million, state-of-the-art Atkins Technology Center (ATC) with a ground-breaking ceremony held on September 13 in Richland, Wash. Located near the Department of Energy’s Hanford nuclear reservation, the facility will be adjacent to the existing Atkins Engineering Laboratory.

Examining Supply-Side Options to Achieve 100% Clean Electricity by 2035 was written by research staff at the National Renewable Energy Laboratory, so its reliance on solar and wind energy to decarbonize the grid by 2035 is not surprising. But that’s a big ask for any variable energy technology, especially if the nation’s largest source of clean power—nuclear energy—is relegated to a supporting role. Massive additions of solar and wind energy on the order of 2 TW would require a supporting infrastructure of new transmission lines, as well as batteries and hydrogen for daily and seasonal energy storage that would drive demand and capacity requirements higher.

The Hanford tanks, on which building began in 1943, were never supposed to hold waste for many decades. If grouting and disposal had occurred according to plans from the 1980s, this waste would already be in the ground and we would have saved almost $100 billion. (Photo: DOE)

At the end of June, a federal judge approved, with the agreement of the Washington State Department of Ecology, a request to push back the deadline 20 months for beginning nuclear waste treatment at the $17 billion Waste Treatment and Immobilization (Vit) Plant at the Hanford Site because of pandemic-related delays. The Direct-Feed Low-Activity Waste program is the Department of Energy’s plan to start treating low-level radioactive waste first at the Vit Plant and then start treating high-level radioactive waste sometime in the 2030s.

This is the fifth delay granted by the court for the project, which should have begun operations in 2007. In one sense, this delay is good, since turning LLW into glass through vitrification is about as smart as singing into the wind. The chemistry of this waste makes it much better suited to grouting, a treatment used by everyone else in the United States and the world.

Advanced reactor developers are designing many new nuclear energy products, targeting commercial demonstration before 2030. These products aim to provide different products and grid services beyond what is provided by the first generations of commercial nuclear plants, namely, gigawatt-scale electricity production. These reactors are intended for deployment in many novel scenarios, including being closer to population centers. They will be sited in governmental processes that encourage far more public participation than was possible when many of the existing plants were sited and built in the 1960s and 1970s. This means that community engagement and approval likely will be critical for project success. This article, which discusses this issue of social license, is an adaptation of “Social license in the deployment of advanced nuclear technology,” published in Energies in 2021.¹ A more detailed discussion can be found in the original article.

Nuclear power generation surpassed coal generation in the United States for the first time in 2020. As utilities continue to retire coal-fired plants, reusing the shuttered sites to host nuclear reactors could help the nation reach the goal of net-zero emissions by 2050 and prove economically beneficial both for nuclear deployments and for the communities impacted by fossil fuel generation. That’s according to a Department of Energy report released this week, detailing how hundreds of U.S. coal power plant sites that have recently retired or plan to close within the decade could be suitable for new nuclear power plants. Nuclear power’s high capacity factors mean those plants could deliver an added benefit—delivering more baseload power to the grid from the nameplate capacity replacement.

In a first for the Department of Energy’s Oak Ridge Site, a former reactor facility is being demolished. The site’s cleanup contractor, UCOR, began tearing down the Bulk Shielding Reactor, also known as Building 3010, last week.

“While this project is not the biggest demolition we’ve undertaken, it carries a lot of significance,” said Laura Wilkerson, acting manager for the Oak Ridge Office of the DOE’s Office of Environmental Management (EM). “It is the first removal of a former reactor at [Oak Ridge National Laboratory], and it is a signal of much more to come at the site in the immediate future.”

Scientists in the Departments of Radiation Oncology and Medicine at the University of Washington (UW) and Fred Hutchinson Cancer Center (Fred Hutch) are directly targeting cancerous cells traveling through patients’ bloodstreams with diseases such as leukemia and lymphoma using an intravenous injection of the radioactive isotope astatine-211 (At-211). The work, its challenges, and its promise were described in a recent news release from the National Isotope Development Center (NIDC), which is managed by the Department of Energy’s Isotope Program.

The Department of Energy is offering cost-shared funding that could lead to the demonstration of an “energy park” drawing 20–300 MW of thermal energy from a U.S. nuclear power plant under a funding opportunity amendment issued in August by the DOE’s Office of Nuclear Energy Light Water Reactor Sustainability (LWRS) program, in coordination with the DOE’s Office of Energy Efficiency and Renewable Energy Hydrogen and Fuel Cell Technologies Office.

Those who welcomed the $700 million earmarked for high-assay low-enriched uranium (HALEU) supply in the Inflation Reduction Act of 2022 (IRA) in August have cause to celebrate again. The White House sent a supplemental appropriation request to Congress on September 2 that would provide more than double the IRA funds if passed—$1.5 billion—for the Department of Energy’s Office of Nuclear Energy to build a reliable supply of both low-enriched uranium for existing U.S. nuclear power plants and HALEU for the advanced reactors that will be built within the decade.

Work is nearing completion on a fourth basin needed to ensure adequate storage for wastewater during tank waste treatment on the Department of Energy’s Hanford Site, in Washington state.

According to the DOE, its operations contractor Washington River Protection Solutions (WRPS) has made significant progress on Basin 41 at the Liquid Effluent Retention Facility (LERF) since concrete was first poured for the perimeter one year ago.

The Department of Energy’s Calcine Retrieval Project (CRP) at the Idaho National Laboratory Site is progressing toward what is likely to be a first: flying a light detection and ranging-equipped drone inside a high-level radioactive waste vault to map its interior.

The reports of the death of the Diablo Canyon nuclear power plant may be greatly exaggerated. While Pacific Gas and Electric (PG&E) announced as early as 2016 that it would be closing California’s last operating nuclear power plant at the end of its current operating license, there has been growing political pressure to keep the plant, and its 2,200 MWe of carbon-free energy, running.

Crews at the Department of Energy’s Hanford Site in Washington state recently finished testing “bubblers” at the Waste Treatment and Immobilization Plant. Bubblers are used to transform radiological and chemical tank waste into a glass form for safe disposal.

The Department of Energy’s National Nuclear Security Administration has redirected about $10 million from the International Atomic Energy Agency’s low-enriched uranium fuel bank to efforts supporting the peaceful uses of nuclear technology and to fight cancer.

Washington state’s Department of Ecology and the U.S. Department of Energy have agreed on a plan for how to respond to two underground tanks that are leaking radioactive waste, as well as any future tank leaks, at the Hanford Site near Richland, Wash.

In April 2021, following a year-long leak assessment, the DOE announced that Hanford’s Tank B-109 is leaking waste into the surrounding soil. Tank T-111 was discovered to be leaking in 2013. Currently, Tank B-109 is leaking about 1.5 gallons of waste per day, and Tank T-111 is leaking less than a gallon a day, according to the DOE.

The Solid Waste Management Facility (SWMF) at the Department of Energy’s Savannah River Site recently was subject to an enhancement program designed to improve procedure format and quality. The program has led to a greater efficiency and a streamlined procedure review process at the facility, according to the DOE’s managing and operating contractor at SRS.

X-energy has been having a good year. Not only did Dow announce plans to invest in the company’s high-temperature gas reactor (HTGR) technology and deploy an Xe-100 reactor at a U.S. Gulf Coast facility for power and process heat by 2030, in parallel with the Xe-100 demo planned for Washington state with support from the Advanced Reactor Demonstration Program (ARDP), but X-energy’s fuel subsidiary, TRISO-X, has applied for a fuel facility license and aims to have a commercial fuel plant operating in 2025, and Canadian provinces are signaling their interest in the technology. And while news of Dow’s investment broke with well-deserved fanfare, the company’s serious interest in HTGRs—and federal support for HTGR development—goes way back.

Delivery of electricity from fusion is considered by the National Academies of Engineering to be one of the grand challenges of the 21st century. The tremendous progress in fusion science and technology is underpinning efforts by nuclear experts and advocates to tackle many of the key challenges that must be addressed to construct a fusion pilot plant and make practical fusion possible.

The Department of Energy has chosen Los Alamos National Laboratory to lead a $9.25 million collaborative project to model the behavior and properties of structural materials in molten salt through the Scientific Discovery through Advanced Computing (SciDAC) program and announced the news August 9. The team working on the five-year project includes experts from LANL; Carnegie Mellon University; and Idaho, Lawrence Berkeley, and Sandia national laboratories.
