Research & Applications

The Advanced Research Projects Agency–Energy (ARPA-E), a branch of the Department of Energy, is tasked with driving the research and development of cutting-edge energy technologies. The agency’s core emphasis is on mitigating emissions, increasing energy efficiency, reducing imports, ensuring energy systems resiliency, and offering transformative solutions for the management of radioactive waste and spent nuclear fuel (SNF). Its mission is instrumental in ensuring the United States retains its technological superiority in the design and implementation of new energy technologies. Efforts in SNF research also benefit prior investments in ARPA-E’s MEITNER (Modeling-Enhanced Innovations Trailblazing Nuclear Energy Reinvigoration) and GEMINA (Generating Electricity Managed by Intelligent Nuclear Assets) programs, which seek to substantially decrease the capital and operational expenditures associated with advanced reactors (ARs).

The Department of Energy’s Office of Science announced $5.8 million in funding on September 13 for five projects to benchmark nuclear data for a range of nuclear science investigations and applications, including energy, space exploration, and nonproliferation. Four of the five funded projects include participation from Brookhaven National Laboratory.

The Department of Defense announced on September 13 that it has awarded a contract option to X-energy for the “enhanced engineering design” of a microreactor that could serve as the transportable power source envisioned by the Strategic Capabilities Office’s (SCO) Project Pele. The DOD expects the award for one year of work to “allow a thorough analysis of design options,” resulting in a preliminary engineering design and “initiation of a regulatory preapplication process.”

Having decided “to not associate to the Euratom Research and Training program (Euratom R&T) and, by extension, the Fusion for Energy Program,” the government of the United Kingdom announced plans on September 7 to support its homegrown UK Fusion Strategy by investing up to £650 million (about $811.8 million) through 2027 in a suite of research and development programs to support the country’s fusion sector and strengthen international collaboration. The funds are in addition to the £126 million (about $157.3 million) announced in November 2022 to support U.K. fusion R&D.

The Department of Energy announced $29 million in funding for seven team awards for research in machine learning, artificial intelligence, and data resources for fusion energy sciences on August 31. In all, 19 institutions will build algorithms to address high-priority research opportunities in fusion and plasma sciences using interdisciplinary collaborations of fusion and plasma researchers teamed with data and computational scientists.

The Freemelt ONE 3D printer.

Hungary’s Institute for Nuclear Research (ATOMKI) is set to take delivery this year of a 4.6 million Swedish krona ($414,300) electron-beam 3D printer for nuclear material science research.

The printer—the Freemelt ONE model—is manufactured by Freemelt, a Swedish company.

Research plans: ATOMKI intends to use the printer for “research in surface science [and] surface topology, which means creation of new surface structures and composite materials via non-adiabatic [not occurring without heat loss or heat gain] alloying,” according to Kalman Vad, a senior research associate at ATOMKI. “The open architecture and free parametrization of the properties of the [electron] beam makes Freemelt ONE an ideal tool for research purposes.”

Deploying microreactor technology for military applications could have huge impacts on logistics and reliability for the military of the future, and on the commercial use of similar technologies. That’s why the Department of Defense is developing Project Pele—a high-temperature, gas-cooled and TRISO-fueled microreactor, transportable within mobile shipping containers—for testing at Idaho National Laboratory in 2025.

A group of researchers analyzed recent updates to the International Nuclear Workers Study (INWORKS) and published their findings—“Cancer mortality after low dose exposure to ionising radiation in workers in France, the United Kingdom, and the United States (INWORKS): cohort study”—in the journal BMJ on August 16. The multinational research team, led by David B. Richardson of the University of California–Irvine, reports “evidence of an increase in the excess relative rate of solid cancer mortality with increasing cumulative exposure to ionizing radiation at the low dose rates typically encountered by French, U.K., and U.S. nuclear workers [and] evidence in support of a linear association between protracted low dose external exposure to ionizing radiation and solid cancer mortality.”

Bruce Power, the utility in Ontario, Canada, and health-care company Nordion announced that they are working to increase the production of cobalt-60 to meet increasing world market demands. The companies said they will increase the amount of Co-60 Bruce Power is able to produce in its reactors “by innovating a new adjuster component configuration.”

It’s been almost 35 years since Illinois last added a nuclear power reactor to the grid (Braidwood-2, a pressurized water reactor operated by Constellation, reached commercial operation in October 1988). And it’s been 63 years since a research reactor reached initial criticality at the University of Illinois–Urbana-Champaign (UIUC). The university’s TRIGA Mark II started up in August 1960 and was shut down in 1998. For about 25 years, UIUC—the flagship public university in a state that generates more power from nuclear energy than any other—has lacked an operating research reactor.

Advanced reactors are promising energy systems that can enable the world to transition to a more sustainable energy matrix. These concepts are potentially more fuel efficient and safer, compared with previous generations of nuclear reactors. Many designs, like high-­temperature gas reactors (HTGRs) and molten salt fast reactors (MSFRs), target high outlet temperatures, allowing for their operation in processes where high heating is required, such as for hydrogen production and desalination.

The United States has joined the OECD Nuclear Energy Agency (NEA) Data Bank, a decision that marks “a significant stride in international collaboration for nuclear energy research, safety, and knowledge exchange,” according to the August 16 NEA announcement. “As a country renowned for its scientific and technological excellence, the United States will undoubtedly enrich the Data Bank's repository of data, software, and benchmarks and enhance its role in fostering responsible nuclear development.”

The Department of Energy’s Office of Science announced $112 million in funding on August 14 for 12 projects designed by fusion scientists, applied mathematicians, and computer scientists to apply high-performance computing and exascale computers to complex fusion energy problems.

The list of projects and more information can be found on the Fusion Energy Sciences homepage.

As global concerns about climate change and energy sustainability intensify, the need for cleaner and more efficient energy sources is more critical than ever. Nuclear power consistently emerges as an important part of the solution, driving the development of innovative technologies. While numerous fission technologies were built and proven in the early days of nuclear energy, times and regulations have changed. Between the 1950s and mid-1970s, Idaho National Laboratory built 52 reactors—then paused for five decades. Can this nation return to the frontier once again, embarking on new fission technologies? With a mature regulatory environment and increasing public support, how quickly can a new non–light water system be deployed in modern times?

General Fusion announced on August 9 that it will build a fusion machine called Lawson Machine 26 (LM26) at the company’s new headquarters in the city of Richmond, British Columbia, near Vancouver. The machine is intended to achieve fusion conditions of over 100 million degrees Celsius by 2025 and progress toward scientific breakeven by 2026 to support the company’s vision of commercial fusion energy by the early to mid-2030s.

The Nuclear Regulatory Commission has issued a new report, Metal Fuel Qualification--Fuel Assessment Using NRC NUREG-2246, “Fuel Qualification for Advanced Reactors,” which documents experience with the zirconium-clad ceramic fuel system in fast reactors and presents the fuel qualification case for a data-supported fuel design and set of operating conditions. The research includes identifying as-fabricated conditions (e.g., dimensions, chemistry) and in-pile conditions (e.g., linear heat generation rates, burnup, temperature) and anticipated operational occurrences.

Type One Energy Group, a Madison, Wis. –based stellarator fusion energy company, announced the opening of new offices in Oak Ridge, Tenn., during the East Tennessee Economic Council’s fifth annual NOW Conference, held August 1–2 in Knoxville.

Type One Energy’s expansion into Oak Ridge follows the company’s recent funding of an oversubscribed seed round of $29 million. The company is also one of eight fusion developers that was selected by the Department of Energy in late May to receive a total of $46 million in funding to kick off the public-private Milestone-Based Fusion Development Program, aimed at developing fusion pilot plant designs.

SHINE Technologies, a Wisconsin-based medical isotopes and fusion technology company, announced today that it has demonstrated clearly visible Cherenkov radiation produced by fusion for what is believed to be the first time in history. Cherenkov radiation is the characteristic blue glow typically seen in underwater fission reactions.

15 years into an epic journey to realize the potential of the most abundant and safest nuclear fuel and critical material known to man. Thorium Energy Alliance (T.E.A.) has made world changing progress in reviving the many uses of thorium and its allied companion elements.

Sometimes, even with decades of research and testing, a project never gets off the ground. That has been the case for U.S. nuclear thermal rockets—so far. Research began in the 1950s and peaked with a series of rigorous ground tests for NERVA—the Nuclear Engine for Rocket Vehicle Applications—before the program was canceled in 1973. Five decades on, this technology has yet to make it to the launchpad. But while mission priorities shift, the physics is solid: Fission-powered nuclear thermal rockets (NTRs) still offer two to five times greater efficiency than conventional rockets.
