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.

Canadian Nuclear Laboratories (CNL) and General Fusion have announced a memorandum of understanding (MOU) to “develop fusion energy research capabilities within CNL, to support the goal of constructing a potential General Fusion commercial power plant in Canada before 2030.” The plant would follow on a demonstration-scale plant that General Fusion wants to have operating in the United Kingdom by 2027 to validate the performance and economics of the technology.

Just days before COP27 and the U.S. midterm elections, the White House announced $1.55 billion in Inflation Reduction Act (IRA) funding for national laboratories and the launch of a Net-Zero Game Changers Initiative based on a new report, U.S. Innovation to Meet 2050 Climate Goals. Out of 37 research and development opportunities identified, fusion energy was selected as one of just five near-term priorities for the new cross-agency initiative. Together, the announcements signal policy and infrastructure support for fusion energy—the biggest chunk of Department of Energy Office of Science (DOE-SC) IRA funding went to ITER, via Oak Ridge National Laboratory—and for advanced nuclear technologies to power the grid and provide process heat to hard-to-decarbonize industrial sectors.

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.”

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.

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.

Future fusion energy facilities will continue to be regulated by the Environment Agency (EA) and Health & Safety Executive (HSE), the U.K. government announced June 20, and existing law on nuclear regulations will be amended to exclude fusion energy facilities from nuclear fission regulatory and licensing requirements. The move was announced by the United Kingdom Atomic Energy Authority (UKAEA) with the expectation it would provide “clarity to developers of prototype/demonstration fusion facilities currently being planned to support rapid commercialization.”
Session moderator Scott Hsu (left) led a discussion with (from left) Troy Carter, Kathy McCarthy, Artem Smirnov, Satoshi Konishi, and Jane Hotchkiss during an ANS Annual Meeting executive session on “The New Fusion Outlook.”
A “bold decadal plan” to accelerate fusion research, development, and demonstration in partnership with the private sector emerged from a March 2022 White House Fusion Summit and inspired the June 14 ANS Annual Meeting executive session titled “The New Fusion Outlook.” Moderator Scott Hsu, who is leaving a role as a program director for the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) to become a senior adviser to the DOE’s undersecretary for science and innovation as well as lead fusion coordinator for the DOE, ably led a panel of fusion stakeholders representing universities, national laboratories, private fusion companies, and public policy and communication. The discussion intended to bring attendees with fission experience up to speed on the rapidly accelerating area of fusion energy and explore how the fusion energy community can work toward a unique path for fusion energy regulation and public engagement.

A new record has been set by the world’s largest operating tokamak, the Joint European Torus (JET). According to the EUROfusion scientists and engineers who work on JET at the U.K. Atomic Energy Authority’s Culham Centre for Fusion Energy, the landmark experiment, announced on February 9, which produced 59 megajoules of fusion energy over five seconds, is powerful proof of fusion’s potential as a clean energy source.
