Research & Applications

Regardless of how you power our grid or how you attempt to decarbonize our economy, we will need many various metals to achieve any future, or even to just continue with business as usual. Critical metals like cobalt, lithium, nickel, and neodymium are essential to a low-carbon-energy future if renewables and electric vehicles are to play a large role.¹ Even if nuclear provides 100 percent of our power, just operating the grid and electrifying most sectors will take huge amounts of critical metals like copper, notwithstanding the fact that nuclear power requires the least amount of metals and other materials of any energy source.

Researchers at the Department of Energy’s Oak Ridge National Laboratory want to make the sensors in nuclear power plants more accurate by linking them to electronics that can withstand the intense radiation inside a reactor. Electronics containing transistors made with gallium nitride, a wide-bandgap semiconductor, have been tested in the ionizing radiation environment of space. Now, according to a June 24 article from ORNL, tests carried out in the research reactor at Ohio State University indicate they could withstand neutron bombardment within a nuclear fission reactor.

The Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) announced June 20 that two companies—one power plant operator and one advanced reactor developer—are getting vouchers to access the extensive nuclear research capabilities and expertise available across the DOE national laboratories in the third round of GAIN vouchers awarded for fiscal year 2024. 

Natura Resources, which is supporting the construction of a molten salt research reactor on the campus of Texas’s Abilene Christian University, announced in mid-June that it expects the Nuclear Regulatory Commission to complete its safety assessment and issue a permit for the nonpower test reactor in September.

Wisconsin-based fusion technology company SHINE Technologies announced today the signing of a memorandum of understanding with Zeno Power to develop a nuclear materials supply chain for its commercially available radioisotope power systems (RPSs). Under the MOU, SHINE plans to provide Zeno with strontium-90 to power its RPSs, which are capable of providing continuous power in harsh environments.

Orano Group subsidiary Orano Med, a developer of targeted alpha therapies for oncology, inaugurated its first ATLab (Alpha Therapy Laboratory) earlier this month. Located in Brownsburg, near Indianapolis, Ind., ATLab Indianapolis is an industrial-scale pharmaceutical facility dedicated to the production of lead-212–based radioligand therapies.

Targeted alpha therapy has shown to be effective in treating various oncological diseases, combining the natural ability of biological molecules to target cancer cells with the short-range cell-killing capabilities of alpha emissions generated by Pb-212. With a half-life of 10.64 hours, along with a decay product of the short-lived alpha-emitter bismuth-212, Pb-212 allows for the possible synthesis and purification of complex radiopharmaceuticals with minimum loss of radioactivity during preparation.

The development of radiopharmaceuticals has long been hampered by the difficulty of manufacturing and distribution on an industrial scale, Orano said, adding that the construction of ATLab Indianapolis is a major step toward making these new treatments available to cancer patients with high unmet needs in North America.

Infinity Power has developed a nuclear battery that it says generates electrical power from radioisotopes with 60 percent overall efficiency, exceeding that of other radioisotope energy conversion methods, which are typically less than 10 percent. The company believes its technology—developed in part under contracts from the Department of Defense—has potential for “next-generation radioisotope power sources.”

Radiant Industries announced on June 4 that the safety design strategy (SDS) for a test of its Kaleidos microreactor in the National Reactor Innovation Center’s DOME test bed at Idaho National Laboratory now has approval from the Department of Energy. Radiant hopes to test Kaleidos—a 1-MW high-temperature, gas-cooled reactor—by 2026 and then market portable commercial reactors to power remote locations and provide backup or primary power for critical applications in hospitals or for disaster relief.

Sterile mosquitoes are being used to reduce the population of insecticide-resistant Aedes aegypti mosquitoes in Fort Myers, Fla., which can spread viruses including dengue, yellow fever, Zika, and chikungunya.

Just one week after the White House Office of Science and Technology Policy hosted a summit on domestic nuclear deployment, they filled a room again on June 6 for a livestreamed event cohosted with the Department of Energy to announce a new DOE fusion energy strategy and new public-private partnership programs, and to hear directly from stakeholders—including scientists, private fusion companies, investors, and end users—during panel discussions on fusion science and technology progress and the path to fusion energy commercialization.

Xcimer Energy announced June 4 that it has raised $100 million in Series A financing for a new facility in Denver, Colo., that will host a prototype laser system with “the world’s largest nonlinear optical pulse compression system.” As a private fusion developer, Xcimer wants to “extend the proven science of inertial fusion to industrial scale” with the help of that laser system and “key technologies and innovations from multiple fields.”

A new theoretical model about stabilizing plasma in tokamak fusion reactors is described in three papers from a study that was led by research physicist Jason Parisi of Princeton Plasma Physics Laboratory. Two papers—“Kinetic-ballooning-limited pedestals in spherical tokamak plasmas” and “Stability and transport of gyrokinetic critical pedestals”—appear in the International Atomic Energy Agency journal Nuclear Fusion. The other paper—“Kinetic-ballooning-bifurcation in tokamak pedestals across shaping and aspect-ratio”—appears in Physics of Plasmas.

Researchers at the DIII-D National Fusion Facility, the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (LBNL), and the Energy Sciences Network (ESnet) are teaming up to make the high-performance computing (HPC) powers of NERSC available to DIII-D researchers through ESnet—a high-speed data network. Their collaboration, described in a May 29 news release, in effect boosts the computing power behind DIII-D’s diagnostic tools to make more data from fusion experiments available to researchers at DIII-D in San Diego and to the global fusion research community.

Last Energy, a Washington, D.C.-based microreactor developer, announced last week a partnership with the NATO Energy Security Centre of Excellence (ENSEC) to jointly research military applications for microreactor power and explore opportunities for future microreactor deployments on NATO military installations.

The Department of Energy’s Office of Fusion Energy Sciences (FES) wants Fusion Innovation Research Engine (FIRE) collaboratives to be a bridge between FES’s basic science research programs and the growing fusion industry. A funding opportunity announcement released May 22 explains that FIRE will be a “transformative initiative aimed at creating a fusion innovation ecosystem” with virtual, centrally managed collaboratives working on “end-use inspired” fusion science and technology R&D.

Europe’s first Mars rover—named Rosalind Franklin—was months away from a planned September launch when the European Space Agency (ESA) convened a meeting a few weeks after Russia’s February 2022 invasion of Ukraine. The ESA Council unanimously agreed on “the present impossibility” of working with Roscosmos as its launch partner and later decided to reboot its ExoMars mission with a new lander, new partners, and a new launch date.
