The discussion about nuclear fusion has long involved its potential to create limitless amounts of energy. Thea Energy is one of several companies working to turn that potential into reality.

For the U.S., keeping up with AI’s insatiable appetite is the biggest systemic risk of the next decade. America needs a massive expansion of power plants, transmission lines, and advanced hardware, while using AI itself to drive grid progress and optimize power distribution.

The Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), Type One Energy and the University of Tennessee in Knoxville are partnering to establish a world-class facility that will drive American innovation and move fusion energy closer to reality. This high-heat flux (HHF) facility, located at the Tennessee Valley Authority’s (TVA) Bull Run Energy Complex in East Tennessee, will evaluate how materials react under extreme conditions in a fusion device.

The electricity sector faces a timing problem that’s becoming impossible to ignore. Data centers, artificial intelligence (AI) deployment, industrial reshoring, and broader electrification are driving load growth at rates not seen in decades—and much of that new demand wants carbon-free, firm power. Nuclear checks those boxes. But can the industry deliver capacity fast enough? POWER […]

For much of the 20th century, the U.S. set the global standard for civilian nuclear energy. American innovation shaped reactor design, safety culture, and regulatory practice worldwide. Yet today, as nuclear power regains prominence amid concerns over climate, energy security, and industrial competitiveness, America faces a quieter but more consequential challenge: the erosion of its nuclear fuel supply chain.

Recent breakthroughs at U.S. fusion labs, along with new public-private partnerships, are bringing us closer than ever to realizing fusion energy’s limitless potential. However, the U.S. has a major gap to fill in fusion research and development (R&D), and workforce development.

The state’s Public Service Commission on December 30 issued a 14-page order in which the group approved Constellation’s request to fast-track the facilities in the regulatory process.

Entergy Arkansas, the utility that provides electricity to about 735,000 customers in 63 counties in that state, announced a plan to add about 2.6 GW of new power generation capacity, in part by converting old coal-fired units to burn natural gas. It also is renewing the operating license for the 1.8-GW Arkansas Nuclear One power plant, the state’s only nuclear power station, with plans to invest in new equipment that would increase the facility’s output.

Local government officials in Japan have given approval for the restart of a reactor at the world’s largest nuclear power plant. The Kashiwazaki-Kariwa facility, where seven reactors have total generation capacity of nearly 8,000 MW, has sat idle since early 2012 in the wake of the Fukushima nuclear disaster in 2011, which caused Japan to shut down its nuclear power industry.

A Bulgarian energy company, along with a European project developer, has signed a letter of intent for a joint venture (JV) that could build a fleet of as many as six small modular reactors (SMRs) in the country. Blue Bird Energy AD and SGE S.A. on December 22 announced the JV would deploy BWRX-300 SMRs from GE Vernova Hitachi (GVH).

The fusion industry just achieved a major milestone—and this time, it’s not about science.

The Trump Media & Technology Group (TMTG) is merging with a California-based company focused on development of nuclear fusion in a $6-billion deal. The all-stock transaction announced December 18 would create one of the first publicly traded fusion companies.

Three advanced nuclear developers—Radiant, Last Energy, and ARC Clean Technology—announced the closing of major private funding rounds in mid-December 2025, signaling renewed investor momentum behind microreactors and small modular reactors (SMRs) as the companies move from design and licensing into pilot deployment and early commercialization. The announcements—which span a new $300-million-plus round at Radiant, an […]

An energy company focused on supporting artificial intelligence (AI) through infrastructure has signed a memorandum of understanding (MOU) with a Utah-based nuclear power services company, as the groups evaluate ways to provide electricity for a massive data center campus in that state.

The past year saw a multitude of factors driving up electricity prices, including rapid growth in electricity demand, supply chain tightness, deployment delays for transmission and production projects, and an uncertain political and permitting climate. We expect all of these trends to continue in 2026. Changing economics have turned the justification for project development in […]

Idaho National Laboratory (INL) has selected the five commercial teams that will potentially demonstrate advanced applications—including data center integration—at its much-watched Microreactor Application Research Validation and Evaluation (MARVEL) platform, an 85-kWth/20-kWe liquid-metal-cooled test bed currently under construction at the lab. The initial selections, unveiled on Dec. 4, mark the “first potential end users for MARVEL,” […]

Framatome said it has been awarded a contract to upgrade several digital control systems at Energy Northwest’s Columbia Generating Station. The scope of the project includes system design, engineering, manufacturing, testing and installation for new digital feedwater level control and feedwater heater vents and drains systems. The upgrades announced December 4 are part of Energy […]

Antares, an advanced nuclear energy startup, announced the close of its $96-million Series B funding round, which was led by Shine Capital with participation from Alt Capital, Caffeinated, FiftyThree Stations, Industrious, and other investors.

The Unit 2 reactor at the Shimane nuclear power station resumed operation in January 2025, more than a decade after it, and all other reactors in Japan, were taken offline. Japanese officials want restarted nuclear units to help supply needed power and lower the cost of energy across the country.

Framatome has been selected by Electrabel, part of ENGIE Group, to modernize the rod control system of the Tihange 3 nuclear reactor in Belgium.

In the race to decarbonize and secure America’s energy future, nuclear power is once again in the spotlight. From advanced reactors to fusion breakthroughs, the promise of nuclear energy is clear.
