The same high energy density that makes nuclear energy a clean and efficient source of power could make it a good alternative to defend the planet against catastrophic asteroid impacts. NASA demonstrated the world’s first planetary defense technology in September 2022 by deliberately crashing a “kinetic impactor”—a heavy, box-like spacecraft—into an asteroid. Now, researchers at Lawrence Livermore National Laboratory have developed a new tool to model how a nuclear device could deflect—or even destroy—an asteroid threat to Earth in a more efficient and controlled way.

The Department of Energy recently announced that it was establishing three inertial fusion energy (IFE) hubs and funding them with a total of $42 million over four years. The leaders of the three hubs selected by competitive peer review—Colorado State University, Lawrence Livermore National Laboratory, and the University of Rochester—all issued press releases touting the attributes and plans of their facilities and their research collaborators on the same day—December 7.

What’s happening in big fusion? A global update

December 5, 2023, 9:35AMNuclear News

One year ago today, researchers at Lawrence Livermore National Laboratory achieved a record shot at the National Ignition Facility (NIF) that set the world talking about the potential of fusion energy. And the buzz hasn’t stopped. Fusion energy is getting its most significant attention yet on the world stage at COP28 in Dubai, UAE, where John Kerry, U.S. special presidential envoy for climate, delivered a keynote address today titled “An inclusive fusion energy future,” followed by a panel discussion.

Lawrence Livermore National Laboratory hosted current and former staff, government officials, and media on May 8 to celebrate the lab’s achievement of fusion ignition at the National Ignition Facility (NIF) on December 5, 2022. Energy secretary Jennifer Granholm and undersecretary for nuclear security and National Nuclear Security Administration administrator Jill Hruby were in attendance, and Granholm took the opportunity to announce funding of up to $45 million to support inertial fusion energy (IFE) research and development. The Department of Energy’s Office of Science (DOE-SC) wants to establish multiple IFE Science and Technology Innovation Hubs (IFE S&T hubs), with total funding for 2023 of up to $9 million for projects lasting up to four years in duration.

Fusion energy research has seen exciting recent breakthroughs. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory has achieved ignition,1,2 and in the United Kingdom, the Culham Centre for Fusion Energy’s Joint European Torus (JET) has produced a record 59 megajoules of fusion energy.3 Against this backdrop of advances, we provide an account of the earliest fusion discoveries from the 1930s to the 1950s.* Some of this technical history has not been previously appreciated—most notably the first 1938 reporting of deuterium-tritium (DT) 14-MeV neutrons at the University of Michigan by Arthur Ruhlig.4 This experiment had a critical role in inspiring early thermonuclear fusion research directions. This article presents some unique insights from the extensive holdings within Los Alamos National Laboratory’s archives—including sources typically unavailable to a broad audience.

From “never” to now: NIF through the lens of 60 Minutes

“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.

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.

Breakeven breakthrough at the National Ignition Facility

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.

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.

Just over one year ago, on August 8, 2021, researchers achieved a yield of more than 1.3 megajoules (MJ) at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) for the first time, achieving scientific ignition and getting closer to fusion gain.

The scientific results of the historic experiment were published exactly one year later in three peer-reviewed papers: one in Physical Review Letters and two (an experimental paper and a design paper) in Physical Review E. In recognition of the many individuals who worked over decades to enable the ignition milestone, more than 1,000 authors are included on the Physical Review Letters paper.

Operators at the Savannah River Site’s Solid Waste Management Facility can now characterize and certify newly generated TRU waste through the use of a real-time radiography unit that uses an X-ray system to examine the contents of waste containers. The equipment was recently installed to meet updated requirements set by the Department of Energy’s National TRU Program that involve evaluating the containers for chemical compatibility and oxidizing chemicals.

The shipments of TRU waste from SRS, in South Carolina, are sent to the Waste Isolation Pilot Plant (WIPP), in New Mexico, for disposal.

One of the last remaining milestones in fusion research before attaining ignition and self-sustaining energy production is creating a burning plasma, where the fusion reactions themselves are the primary source of heating in the plasma. A paper published in the journal Nature on January 26 describes recent experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) that have achieved a burning plasma state.

Omar Hurricane: Scientific proof of principle at the NIF

January 14, 2022, 7:00AMNuclear News

Hurricane

In 2012, Omar Hurricane, a distinguished member of the technical staff at Lawrence Livermore National Laboratory, was asked by the laboratory director to lead a team to delve into studying the physics and engineering obstacles preventing fusion ignition at the National Ignition Facility (NIF). The team’s efforts led to a new exploratory “basecamp” strategy and the creation of several pivotal experiments that revealed some of the underlying problems with the ignition point design, while also delivering improved fusion performance and the first evidence of significant alpha particle self-heating.

Hurricane was appointed chief scientist of the Inertial Confinement Fusion Program in 2014, a position he has held ever since. He was named a Fellow of the American Physical Society’s Division of Plasma Physics in 2016 and was recently awarded the Edward Teller Medal from the American Nuclear Society for his work on inertial confinement fusion physics.
