5,500 Superconducting Wires Survive Intense Testing for World’s Largest Fusion Reactor

gizmodo.com Gayoung Lee 2025-09-27 01:30:05

Stakeholders around the world are vying to realize nuclear fusion—a fossil fuel alternative that promises maximum energy generation with minimal environmental risk. Behind the efforts to build the world’s largest fusion reactor is an equally gigantic global collaboration: ITER, which has just announced a major advance in its quest to prove fusion’s viability. In a paper published September 11 in Superconductor Science and Technology, the ITER Collaboration reported completing a key test to vali

The US is trying to kick-start a “nuclear energy renaissance”

arstechnica.com Unknown 2025-09-28 01:23:03

In May, President Donald Trump signed four executive orders to facilitate the construction of nuclear reactors and the development of nuclear energy technology; the orders aim to cut red tape, ease approval processes, and reshape the role of the main regulatory agency, the Nuclear Regulatory Commission, or NRC. These moves, the administration said, were part of an effort to achieve American independence from foreign power providers by way of a “nuclear energy renaissance.” Self-reliance isn’t t

China Takes a Key Step Toward Its ‘Meltdown-Proof’ Nuclear Reactor

gizmodo.com Gayoung Lee 2025-10-24 13:35:51

China’s ambitious plan to dramatically pull back from fossil fuels is perhaps most evident in the explosive growth of its nuclear energy program. The latest news suggests China may be tantalizingly close to bringing self-cooling reactors to practical use—a development with profound safety implications. In a statement earlier this week, the China Institute of Atomic Energy (CIAE) announced that it had recently concluded tests for a residual heat removal system for integral fast reactors (IFRs).

Picking a Spot for NASA’s Lunar Nuclear Reactor Is Trickier Than It Sounds

gizmodo.com Clive Neal 2025-11-13 18:36:22

In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the Moon by the time China plans to land the first taikonaut, what China calls its astronauts, there by 2030. Apart from the geopolitical importance, there are other reasons why this move is critically important. A source of nuclear energy will be

Why the US Is Racing to Build a Nuclear Reactor on the Moon

wired.com Becky Ferreira 2025-12-02 03:31:50

NASA is fast-tracking a plan to build a nuclear reactor on the moon by 2030 under a new directive from the agency’s interim administrator Sean Duffy. The plan revives a decades-old dream of scaling up nuclear power in space, a shift that would unlock futuristic possibilities and test legal and regulatory guidelines about the use of extraterrestrial resources and environments. Duffy, who also serves as President Donald Trump’s secretary of transportation, framed being first to put a reactor on

Physicists Catch ‘Ghost Particles’ Bouncing Off Matter in Record-Breaking Experiment

gizmodo.com Gayoung Lee 2025-12-18 17:00:53

Neutrinos are everywhere. About 100 trillion neutrinos pass through our bodies every second, but they’re so weakly interacting we never notice them. It’s this spooky feature of neutrinos that earned them the nickname “ghost particles.” Antineutrinos, their antimatter counterpart, are also everywhere. Both are notoriously difficult to detect, but physicists are getting better at circumventing their ghostly tendencies, as a recent record-setting measurement demonstrates. When a low-energy neutrin

The U.S. Is Testing Tiny Nuclear Reactors That Can Go Practically Anywhere

gizmodo.com Gayoung Lee 2026-01-20 23:00:42

In contrast to other technological advances, the objective for next-generation nuclear reactors seems to be to scale down, not up—an initiative backed by the Department of Energy (DOE). Earlier this month, the DOE announced a conditional agreement made with private firms Westinghouse and Radiant to conduct the first reactor tests at its Demonstration on Microreactor Experiment (DOME) facility, located at Idaho National Laboratory. These experiments, featuring two trailer-sized microreactors, w

Nvidia wants in on the nuclear renaissance, invests in Bill Gates-backed TerraPower

techcrunch.com Tim De Chant 2026-03-04 06:41:06

TerraPower, the nuclear startup founded and backed by Bill Gates, announced a new $650 million funding round this week. The investment will help the company build its first commercial power plant. Like other nuclear startups, TerraPower has been riding a wave of interest from hyperscalers, data center developers, and, now, chip designers. Nvidia’s venture arm, NVentures, participated in the round, marking its first energy investment. Bill Gates and HD Hyundai, both already on the cap table, al

Valar Atomics comes out of stealth with $19M and a pilot reactor site

techcrunch.com Mike Butcher 2025-11-13 15:40:53

Companies developing small modular nuclear reactors (SMRs) have raised more than $1.5 billion in the past year, as tech companies hunger for power to train AI models and governments decide to commit to the industry. For example, X-energy raised $700 million this month, and Paris-based Newcleo raised $151 million last year, and one would be remiss to not mention the $700 million invested into Oklo, NuScale and Nano Nuclear for similar projects in the U.S. While nuclear fusion still looks relati
