Commonwealth Fusion Systems (CFS) and Tokamak Energy Inc. are the two magnetic confinement tokamak fusion developers to receive a portion of the $46 million in funding announced by the Department of Energy in late May for the first 18 months of a public-private Milestone-Based Fusion Development Program aimed at developing fusion pilot plant designs and resolving related scientific and technological challenges within five to 10 years.

“It is critical after the Hamaoka Nuclear Power Station restart that we reduce our cost and increase our capacity factor while becoming more economically competitive.” Ichiro Ihara, chief nuclear officer of Chubu Electric Power, made this observation recently when the Electric Power Research Institute visited the Japanese nuclear power plant for a strategy development session for plant modernization. EPRI’s team of five specialists spent four days at Hamaoka to investigate the feasibility of potential improvements—the third step of the EPRI modernization strategy planning process. It was a trip six months in the making—and the first time EPRI has applied its nuclear plant modernization process outside the United States.

Princeton Stellarators Inc. (PSI) and Type One Energy Group are two of the eight fusion developers selected by the Department of Energy in late May to receive a total of $46 million in funding to kick off a public-private Milestone-Based Fusion Development Program aimed at developing fusion pilot plant designs and resolving related scientific and technological challenges within five to 10 years. The DOE’s selections cover an array of plasma confinement concepts, including the magnetic confinement stellarators being developed by PSI and Type One more than 70 years after the stellarator was first envisioned.

Nuclear Newswire previously took a close look at two of the DOE’s picks: Realta Fusion and Zap Energy (“innovative concept”) and Focused Energy and Xcimer Energy (inertial fusion). Here, we’ll examine how PSI and Type One are engineering solutions to the fusion plasma confinement challenge. Both companies are benefiting from recent advances in computing power and high-temperature superconducting (HTS) magnets. It’s in plans for design, manufacturing, assembly, and control of their stellarators that they differ.

The Gateway for Accelerated Innovation in Nuclear (GAIN) announced June 26 the companies that have received GAIN Nuclear Energy Vouchers, which allow private companies to access the expertise and research capabilities of Department of Energy national laboratories to advance their projects toward commercial deployment. This is the third round of GAIN vouchers awarded for fiscal year 2023; the first round was announced in December 2022 and the second in March.

The future of nuclear power and nuclear science will be informed by the past. But how did “the future” look six decades ago? We’ll check back on the predictions of ANS members in 1965 before assessing the investments in technology, workforce, and licensing needed now.

Like many researchers, I long ago recognized the significance of debates about open access (OA) publishing. However, I did not become too deeply involved, knowing that I alone could not directly influence any outcomes.

Recently, two things changed

The first was the memo from the White House Office of Science and Technology Policy (OSTP)—commonly referred to as the Nelson memo—issued in August last year. In it, grant recipients are guided to provide immediate public access to research papers and data resulting from federally funded research. The second was my election as president of the American Nuclear Society. During my term from June 16, 2022, through June 15, 2023, I faced very concrete decisions that led to the recent launch of ANS's latest publishing venture, Nuclear Science and Technology Open Research (NSTOR).

The World Astatine Community (WAC) was formed earlier this year during the 12th International Symposium for Targeted Alpha Therapy by representatives from the United States, Japan, and the European Union to share astatine production technology and advance science and health care. The National Isotope Development Center (NIDC), which is managed by the Department of Energy’s Isotope Program (DOE-IP), announced the news on June 15 and explained how the United States plans to help expand the global supply of astatine-211.

The Department of Energy announced more than $56 million for 68 nuclear energy projects and student innovation awards across the country on June 15. The projects will support nuclear technology development, early career faculty research activities, and student research at 35 U.S. universities and one national laboratory. Since 2009, the DOE’s Office of Nuclear Energy (DOE-NE) has awarded more than $992 million to advance nuclear energy research and train the next generation of nuclear engineers and scientists.

The question “What about the waste?” is typically thrown out by the antinuclear crowd as an attempt to bog down the discussion of nuclear development. However, with renewed interest in nuclear power—and new advanced reactors in particular—what to do about used nuclear fuel is coming to the fore as a question that needs resolving.

It has been said that the nuclear provisions in the Biden administration’s Inflation Reduction Act are strong enough to be stand-alone bills. The IRA contains various tax incentives for nuclear, to the point where it seems that few in Congress are questioning the importance of nuclear energy to the nation’s power grid and climate goals.

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.

Arndt

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.
