Research & Applications

The Department of Energy announced $150 million in Inflation Reduction Act funding on October 25 for infrastructure improvements at Idaho National Laboratory. According to the DOE, the funding will support nearly a dozen projects at INL’s Advanced Test Reactor (ATR) and Materials Fuels Complex (MFC), both of which have operated for more than 50 years. The investments in existing infrastructure assets mean support for nuclear energy research and development, including fuel testing, bolstering the near-term supply of high-assay low-enriched uranium (HALEU), and reactor demonstrations.

Tokamak Energy on October 26 announced plans to construct a high field spherical tokamak using high-temperature superconducting (HTS) magnets. Dubbed the ST80-HTS, the machine would demonstrate multiple technologies required to achieve commercial fusion energy, the company says. Tokamak Energy plans to complete the ST80-HTS in 2026 to demonstrate spherical tokamak operations and inform the design of its successor, a fusion pilot plant called ST-E1 that the company says could deliver electricity into the grid in the early 2030s and produce up to 200 MWe.

Temperature milestone: Earlier this year, the company’s ST40 spherical tokamak reached the commercial fusion energy plasma temperature threshold of 100 million °C with what was reported as the highest triple product (an industry measure of plasma density, temperature, and confinement) of any private fusion energy company. The ST40 achieved those results with a plasma volume of less than one cubic meter, which is 15 times less volume than any other tokamak that has achieved the same threshold.

General Atomics (GA) announced on October 20 that it has developed a steady-state, compact advanced tokamak fusion pilot plant concept “where the fusion plasma is maintained for long periods of time to maximize efficiency, reduce maintenance costs, and increase the lifetime of the facility.”

Holtec International and Hyundai Engineering & Construction (a Hyundai Motor Group subsidiary) have signed an accord to accelerate the completion of Holtec’s SMR-160 small modular reactor development program, as well as to collaborate on diverse clean energy technologies.

“The world's largest chloride salt system developed by the nuclear sector” is now ready for operation in TerraPower’s Everett, Wash., laboratories. Southern Company, which is working with TerraPower through its subsidiary Southern Company Services to develop molten chloride reactor technology, announced on October 18 that the Integrated Effects Test (IET) was complete. The multiloop, nonnuclear test infrastructure follows years of separate effects testing using isolated test loops, and it was built to support the operation of the Molten Chloride Reactor Experiment (MCRE) at Idaho National Laboratory that the companies expect will, in turn, support a demonstration-scale Molten Chloride Fast Reactor (MCFR).

The Gateway for Accelerated Innovation in Nuclear (GAIN) announced the three recipients of its fourth and final round of 2022 vouchers on October 10. The vouchers were awarded to Curio Solutions, which is developing a spent fuel recycling process, and to two companies that are separately investigating advanced reactor siting—Elementl Power and the Tennessee Valley Authority (TVA). The funds for each award will go directly to Oak Ridge National Laboratory.

The U.K. Atomic Energy Authority (UKAEA) and Tokamak Energy announced on October 10 that they signed a framework agreement to collaborate on developing spherical tokamaks for power production. This news is a complement to last week’s announcement from the U.K. government that the West Burton A coal-fired power plant site in Nottinghamshire has been selected as the future home of STEP (Spherical Tokamak for Energy Production), the U.K.’s planned prototype fusion energy plant. The government is providing £220 million (about $250 million) of funding for the first phase of STEP, which will see the UKAEA produce a concept design by 2024.

Tomorrow, 10/08, is Hydrogen Day, in recognition of the atomic weight of hydrogen: 1.008. Newswire first covered Hydrogen Day in 2021 after the Department of Energy announced its Hydrogen Shot goal to lower the price of clean hydrogen by 80 percent, to $1 per kilogram, within the decade. Now, backed by industry partnerships, new legislation, an eye-popping $7 billion in federal funds for regional clean hydrogen hubs (H2Hubs), a new draft strategy, and on-site progress to pair electrolyzers with nuclear plants, the potential for nuclear-powered production of clean hydrogen is clearer than ever.

The Nuclear Regulatory Commission issued a draft environmental impact statement (EIS) recently on Kairos Power’s application for a permit to construct Hermes, a 35-MW nonpower version of the company’s fluoride salt–cooled reactor design (KP-FHR), at the East Tennessee Technology Park in Oak Ridge, Tenn.

The Department of Energy has opened the application process for its $7 billion program to create regional clean hydrogen hubs (H2Hubs) across the United States. The DOE announced its intention to fund this program in June, the same day that Westinghouse Electric and Bloom Energy announced plans to develop the electrolysis technology that nuclear power plants can use to produce clean hydrogen from water. The DOE H2Hubs program is funded by the recently enacted Bipartisan Infrastructure Law and supports the H2@Scale Initiative to create networks of hydrogen producers, consumers, and local infrastructure. According to the DOE, at least one of the planned hydrogen hubs will use nuclear power to generate the hydrogen.

The Department of Energy announced up to $50 million for a new milestone-based fusion energy development program on September 22. The funding opportunity announcement is open to for-profit companies—possibly teamed with national laboratories, universities, and others—that are prepared to meet major technical and commercialization milestones leading to a pilot fusion power plant design.

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.”

Scientists at Lawrence Livermore National Laboratory and Oregon State University (OSU) have developed a promising new method to isolate and study some of the rarest elements on Earth. Focused first on curium, they have identified three new complexes containing curium ions and revealed the molecules’ 3D structures, as well as previously unknown features.

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.

BWXT Medical has submitted a new drug application to the U.S. Food and Drug Administration to request approval of its technetium-99m generator for medical imaging. A daughter isotope of molybdenum-99, Tc-99m is used in more than 40 million diagnostic procedures annually. BWXT Medical is a subsidiary of Lynchburg, Va.-based BWX Technologies.

Research with the Department of Energy’s Thomas Jefferson National Accelerator Facility (Jefferson Lab) has revealed new insights into short-range correlations—the brief pairings of nucleons (protons with neutrons, protons with protons, or neutrons with neutrons) in the nuclei of atoms. The study, published in Nature, used precision measurements to determine that short-range correlations differ depending on the density of the nucleus, that is, how many nucleons it contains.

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.

Research by scientists at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and collaborating institutions has the potential to improve plasma performance in tokamak nuclear fusion reactors, according to a recent paper in Nuclear Fusion. The research focused on the use of a PPPL-developed dropper to apply coatings of boron powder to the tungsten components inside a tokamak, thereby helping protect the tungsten against the intensely hot plasma. According to lead author Grant Bodner, this process offers “a way to deposit boron coatings without turning off the tokamaks’ magnetic field.”

Core Power, MIT Energy Initiative, and Idaho National Laboratory have secured research funding from the Department of Energy’s Nuclear Energy University Program (NEUP) to conduct a three-year study into the development of offshore floating nuclear power generation. This collaborative research effort is among the 74 nuclear research and infrastructure projects that were awarded more than $61 million by the DOE in June.
