Centrus Energy announced yesterday that it has received Nuclear Regulatory Commission approval to introduce uranium hexafluoride into its 16-machine centrifuge cascade in Piketon, Ohio, following operational readiness reviews by the NRC. Centrus says it “remains on track to begin production of high-assay low-enriched uranium (HALEU) by the end of 2023.” The announcement follows a series of inspections at the American Centrifuge site in April 2023.

Deploying new reactors on the scale required to meet U.S. and international zero-carbon goals by 2050 will require rapid growth in the nuclear workforce, as American Nuclear Society executive director/chief executive officer Craig Piercy emphasized during his opening plenary address at the ANS Annual Meeting on June 12. Piercy pointed to the Department of Energy’s Pathways to Commercial Liftoff: Advanced Nuclear, which estimates that an additional 375,000 people will be required to construct and operate 200 GW of advanced nuclear reactors by 2050—a dramatic increase from about 100,000 today. Where will those engineers, constructors, and operators be found? The 38 nations of the Organisation for Economic Co-operation and Development agreed last week to a new recommendation from the OECD’s Nuclear Energy Agency (NEA) that points to one way to increase the nuclear workforce: increase the number of women participating in the workforce.

The American Nuclear Society’s annual meeting opened on Sunday, June 11, in Indianapolis, Ind., and will run through June 14. The meeting’s theme is “Failure Is Not an Option.”

ANS president Steven Arndt, who ends his yearlong term at the meeting’s end, addressed the audience at the opening plenary on Monday, June 12, noting that nuclear science and technology’s road has been long, but it is up to ANS members and other advocates to push forward the nuclear enterprise’s momentum for a sustainable future.

Before announcing ANS chief executive officer and executive director Craig Piercy to the stage, Arndt thanked the volunteer members, meeting sponsors, and ANS staff, among others, for making ANS meetings happen.

This year, the nuclear power industry is seeing a renewed mandate to innovate and supply carbon-free energy for a range of applications. These new reactor designs feature new fuel forms, expanded thermodynamic ranges, and different operational paradigms. The trend toward smaller designs is anticipated to dramatically reduce siting requirements and enable applications of nuclear heat more customizable to commercial use. This has many vendors and operators imagining creative ways to optimize reactor economics in an unpredictable energy market.

The existing U.S. nuclear fleet has benefited from experience and research generated in research and test reactors around the country. As our industry reinvests in innovation, it will once again turn to many of the same reactors. Those reactors—and the groups such as the National Organization of Test, Research, and Training Reactors (TRTR) that formed to support them—have their own history of innovation.

Realta Fusion of Madison, Wis., and Zap Energy of Everett, Wash., are just two of the eight fusion developers selected by the Department of Energy for funding last week under the public-private Milestone-Based Fusion Development Program. They are the two companies with power plant concepts that don’t fit neatly into established fusion confinement categories. As energy secretary Jennifer Granholm said when she announced the awardees, “Some are working on more technically mature approaches like tokamaks and stellarators and laser inertial fusion, and others are working on innovative concepts with lower technical maturity like mirror and Z-pinch, which could lead to more compact and lower cost systems.”

For almost four decades, the Department of Energy’s Savannah River Site in South Carolina and the Ruth Patrick Science Education Center at the University of South Carolina–Aiken (USC Aiken) have partnered to bring science, technology, engineering, and math (STEM) education to the area's kindergarten through 12th grade students.

Having worked at the U.S. Department of Energy for a decade (1997–2007) and across the energy sector on the Environmental Business International board for 30 years, I have witnessed firsthand the widely shared opinion that the “next big thing” in nuclear will be small modular reactors for urban centers and to provide both heat and power for a variety of energy-intensive sectors. To meet the decarbonization demands of these urban centers, the current energy landscape is pushing many countries away from a “renewables-only” strategy. For example, the German Energiewende (or “energy turnaround”) formally started around 2000 under then chancellor Gerhard Schroeder to phase out nuclear toward mostly renewables (with natural gas backup imported from Russia). As demonstrated by the 2022 gas supply shock and price spikes, Germany created its own nightmare: They now suffer the highest energy prices in Europe, have an unstable grid, and are forced to use more coal.

The Department of Energy released two draft requests for proposals to acquire high-assay low-enriched uranium (HALEU)—one covering enrichment services that could include the production of between 5 and 145 metric tons of HALEU during a 10-year performance period, and another for deconverting that HALEU from uranium hexafluoride (UF₆) gas to metal or oxide forms in preparation for fuel fabrication. The DOE also issued a notice of intent to fulfill its National Environmental Policy Act (NEPA) obligations for the HALEU Availability Program by launching the scoping process for an environmental impact statement; that notice was published in the Federal Register on June 5.

A pair of recent reports by the U.S. Government Accountability Office and the National Academies of Science, Engineering, and Medicine highlight some of the challenges the Department of Energy faces in treating the millions of gallons of legacy radioactive waste at the Hanford Site in Washington state.

Westinghouse Electric Company says its eVinci microreactor technology is “100 percent factory built and assembled before it is shipped in a container to any location.” And “any location” is not restricted to planet Earth, given the company’s goal of sending a scaled-down version of eVinci to the lunar surface or on a mission to provide power in other space applications.

Analysis and Measurement Services Corporation (AMS) has been awarded $500,000 from the Department of Energy for a yearlong project to develop an industry blueprint that should reduce outage times and maintenance costs at nuclear power plants. The project is set to start later this year.

From a crowded field of would-be fusioneers, the Department of Energy has selected eight companies for the public-private Milestone-Based Fusion Development Program to develop fusion pilot plant designs and resolve related scientific and technological challenges within five to 10 years. The DOE announced awards totaling $46 million for an initial 18 months of work on May 31.

Claflin University students recently toured the Department of Energy’s Savannah River Site in South Carolina to learn about the facilities and occupations there.

The United States and Canada will cooperate on spent nuclear fuel management under a statement of intent (SOI) signed between the U.S. Department of Energy and the Nuclear Waste Management Organization, the nonprofit responsible for the management of Canada’s commercial spent fuel.

Since the launch of operations just over a month ago, the Integrated Waste Treatment Unit (IWTU) at Idaho National Laboratory has increased sodium-bearing waste treatment fivefold. This activity is a vital step in removing the remaining liquid waste from nearby underground tanks at the site and protecting the underlying Snake River Plain Aquifer.

The Department of Energy’s Office of Environmental Management (EM) is seeking proposals from small businesses for a nationwide contract to perform deactivation, decommissioning, and removal (DD&R) work, along with waste management and program support services.

Lawrence Livermore National Laboratory hosted current and former staff, government officials, and media on May 8 to celebrate the lab’s achievement of fusion ignition at the National Ignition Facility (NIF) on December 5, 2022. Energy secretary Jennifer Granholm and undersecretary for nuclear security and National Nuclear Security Administration administrator Jill Hruby were in attendance, and Granholm took the opportunity to announce funding of up to $45 million to support inertial fusion energy (IFE) research and development. The Department of Energy’s Office of Science (DOE-SC) wants to establish multiple IFE Science and Technology Innovation Hubs (IFE S&T hubs), with total funding for 2023 of up to $9 million for projects lasting up to four years in duration.

The Molten Salt Reactor Experiment (MSRE) facility is one of hundreds of old, contaminated buildings at Oak Ridge National Laboratory and the Y-12 National Security Complex in Tennessee that are slated to be taken down.

Work crews at the Department of Energy’s Savannah River Site in South Carolina recently replaced a motor on a crane in the 70-year-old H Canyon Chemical Separations Facility. H Canyon is the only production-scale, radiologically shielded chemical separations plant in operation in the United States.

Researchers at Oak Ridge National Laboratory developed a method of using augmented reality (AR) to create accurate visual representations of ionizing radiation, and that technology has just been licensed by Teletrix, a Pittsburgh, Pa.-based firm that develops simulators to train radiological workers and radiological control technicians. ORNL announced the news on May 4.
