Tokamak Energy announced on February 6 that it has built a world-first set of high-temperature superconducting (HTS) magnets, to be assembled and tested in fusion power plant–relevant scenarios.

Ignition and net gain at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) in December 2022 focused global attention on the prospects of inertial fusion energy (IFE). First Light Fusion and the U.K. Atomic Energy Authority (UKAEA) acknowledged the achievement as they announced plans on January 25 to design and build a demonstration facility known as Machine 4 at UKAEA’s Culham Campus in Oxford, U.K., using First Light’s “projectile approach” to IFE. Construction is expected to begin in 2024, and operations are “likely to commence” in 2027.

The Department of Energy’s commitment to breaking down market barriers with initiatives, programs, and access to facilities is making it simpler and more efficient than ever for industry to partner with national laboratories. It is especially timely, as the country continues to face evolving security, economic, and clean energy challenges. Partnering opportunities via the DOE’s Cooperative Research and Development Agreements (CRADAs) and Strategic Partnership Projects (SPPs) are particularly prevalent in the commercial nuclear community and have seen a tremendous amount of funding and support dedicated to advancing the development, demonstration, and deployment of new reactor technologies.

NASA and the Defense Advanced Research Projects Agency (DARPA) have announced they will collaborate on plans to launch and test DARPA’s Demonstration Rocket for Agile Cislunar Operations (DRACO). DARPA has already worked with private companies on the baseline design for a fission reactor and rocket engine—and the spacecraft that will serve as an in-orbit test stand—and has solicited proposals for the next phase of work. Now NASA is climbing on board, deepening its existing ties to DRACO’s work in nuclear thermal propulsion (NTP) technology—an “enabling capability” required for NASA to meet its Moon to Mars Objectives and send crewed missions to Mars. NASA and DARPA representatives announced the development at the American Institute of Aeronautics and Astronautics SciTech Forum in National Harbor, Md., on January 24.

“Star Power” is the name 60 Minutes producers gave their interpretation of the recent experiment at the National Ignition Facility (NIF) that achieved fusion ignition and net gain. Views from inside Lawrence Livermore National Laboratory captured by TV cameras and aired Sunday, January 15—of some of NIF’s 192 lasers, banks of capacitors, target assembly labs, and even the remains of the target assembly blasted in the December 5 breakthrough—are well worth the watch for those of us who are unlikely to visit the site in person.

Researchers at Idaho National Laboratory have completed initial testing on a newly developed fuel test capsule that is expected to provide crucial performance data for sodium-cooled fast reactors. The Department of Energy announced on January 12 that the series of fuel testing experiments being carried out now at INL’s Transient Reactor Test Facility (TREAT) was developed through a joint project between the United States and Japan.

Nuclear medicine company NorthStar Medical Radioisotopes announced that it has successfully produced molybdenum-99 at its recently completed accelerator production facility at its Beloit, Wis., campus. According to NorthStar, the event marks a major milestone in advancing the company’s proprietary electron accelerator technology for the non-uranium–based production of the critical medical radioisotope.

ITER’s machine assembly phase began about two and a half years ago. Now, staff are reversing some of that assembly work to make needed repairs. According to a news article published by the ITER Organization on January 9, ITER is “facing challenges common to every industrial venture involving first-of-a-kind components.” Over one year after problems were first detected and less than two months after they were made public in late November, tests and analysis are producing a clearer picture of necessary repairs to the tokamak’s thermal shield panels and vacuum vessel sectors.
“There is no scandal here,” said ITER director general Pietro Barabaschi. “Such things happen. I've seen many issues of the kind, and much worse.”

Scientists are searching for new materials to advance the next generation of nuclear power plants. In a recent study, researchers at the Department of Energy’s Argonne National Laboratory showed how artificial intelligence could help pinpoint the right types of molten salts, a key component for advanced nuclear reactors.

On December 5, researchers at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory achieved fusion energy breakeven. It was a gain for stockpile stewardship that also—as headlines gushed prior to the Department of Energy’s December 13 announcement—boosted the prospects of inertial fusion energy (IFE). The timing of the landmark achievement may have been especially welcome to private fusion companies with inertial or hybrid magneto-inertial confinement concepts, because it occurred as the DOE was getting ready to consider applications for $50 million in funding for fusion pilot plant design work.

It’s official: Early in the morning on December 5 at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the laser-triggered implosion of a meticulously engineered capsule of deuterium and tritium about the size of a peppercorn yielded, for the first time on Earth, more energy from a fusion reaction than was delivered to the capsule. The input of 2.05 megajoules (MJ) to the target heated the diamond-shelled, spherical capsule to over 3 million degrees Celsius and yielded 3.15 MJ of fusion energy output. The achievement was announced earlier today by officials and scientists representing the Department of Energy and its National Nuclear Security Administration, the White House, and LLNL during a livestreamed event.

A study published recently in the American Physical Society journal Physical Review C reveals new findings about the strong nuclear force, the mysterious fundamental force that holds together the protons and neutrons of the atomic nucleus. Experiments conducted at Argonne National Laboratory have shown how the round, heavy nuclei of the nickel-64 isotope (containing 28 protons and 36 neutrons, making it the heaviest stable Ni isotope) changed into one of two shapes—either like a doorknob or a football—depending on the amount of energy exerted on it. A summary of the research on the Phys.org website compares the nuclei shape change to popcorn kernels changing shape when heated in a microwave.
