DOE Charts Fusion’s Future for U.S. in 2030s Roadmap

The U.S. The Department of Energy has published the final version of its ‘Fusion Science and Technology Roadmap.” It is billed as a “national strategy  to accelerate the commercialization of fusion energy.” (Full text: PDF file) DOE’s goal is to scale up the private fusion sector to support Fusion Pilot Plants (FPP) and deploy commercial, reliable fusion power to the U.S. grid by the mid-2030s.

Make no mistake, this is a big deal because the new focus on sovereign energy security in the coming decades is going to be about fusion with its potential for limitless energy using the same process that drives sunlight and power from stars including our own sun.  The U.S. and China are the global leaders in developing fusion energy. However, European nations, seeking their own version of energy sovereignty, have organized a multi-nation effort to stake out their territory for new fusion power plants. (see next story below)

Building on earlier roadmap efforts, the final version of the  roadmap brings together fusion science, technology, infrastructure, workforce development, and commercialization priorities into a single national strategy to support fusion pilot plants and commercial fusion power in the mid-2030s.

“Fusion energy has entered a new era defined by extraordinary scientific progress and public-private momentum,” said DOE Under Secretary for Science Dr. Darío Gil.

“With this roadmap, we now have the clarity, coordination, and sustained commitment needed to turn the promise of fusion into a reality for the American people.”

Developed with input from more than 800 scientists and engineers across the public and private sectors, the final FS&T Roadmap reflects contributions from more than 15 private companies, 10 National Laboratories, and more than 70 universities. The roadmap identifies the critical science and technology gaps that must be closed to realize fusion pilot plants and strengthen U.S. leadership in the global fusion industry.

With more than $10 billion in private investment already advancing fusion technologies and demonstration projects, DOE is coordinating a national effort to close the remaining technical gaps needed to commercialize fusion energy. 

The roadmap aligns with DOE’s Genesis Mission and will be implemented through the DOE’s newly established Office of Fusion, leveraging artificial intelligence, advanced computing, and public-private collaboration to accelerate fusion research, engineering, and commercialization. 

The activities outlined in the Fusion S&T Roadmap are focused on strategic directions for the DOE to further collaborate with the US fusion industry. DOE’s ability to support this Roadmap’s milestones and timelines of scaling up the domestic fusion private sector by the 2030s is contingent on the development of future public private partnerships. This Roadmap is not committing DOE to specific funding levels, and future funding will be subject to Congressional appropriations.

European Fusion Groups Join Forces for Energy Sovereignty

• The drive for energy sovereignty moves into high gear with a call for a ‘bold, actionable and timely’ strategy

(NucNet) The European Fusion Association (EFA) and Fusion Europe (FE) have begun a “strategic alignment process” as they work to strengthen coordination across Europe’s fusion industry, support more coherent engagement with policymakers and institutions, and ensure that industry is better organised to contribute to the next phase of European fusion policy.

The two groups said the move comes as Europe prepares for the forthcoming EU fusion strategy, a critical moment for industrial competitiveness, energy security and the future fusion value chain.

EFA and FE, both Brussels-based industry groups, said they were calling for a “bold, actionable and timely” EU fusion strategy that matches industry momentum with clear delivery steps. The strategy should support deployment, mobilise investment, strengthen European supply chains, and create the conditions for fusion projects to be built in Europe.

“At a time when fusion is moving from research ambition towards industrial delivery, EFA and FE are taking steps to bring more of Europe’s fusion ecosystem together around a clearer, stronger and more coordinated platform for industry engagement,” a statement said.

“The forthcoming EU fusion strategy will help determine whether Europe converts its scientific excellence, engineering capability and industrial base into deployment, supply-chain value, investment and long-term strategic advantage,” the statement said.

According to the Fusion for Energy Fusion Observatory, global private fusion investment has reached €13 billion ($15 billion), with the US and China together accounting for more than 85% of that funding.

The EU accounts for around 5% of global private fusion funding, underlining the need for Europe to step up its game to create stronger conditions for fusion companies, suppliers and industrial partners to scale.

Tennessee is the First State With Fusion Regulations

(WNN) In 2023, the US Nuclear Regulatory Commission (NRC) announced that it would base its regulatory framework for fusion energy systems on its existing process for licensing the use of byproduct materials: such systems would generate electricity from the energy released when hydrogen atoms are combined to form helium, rather than the splitting, or fission, of uranium atoms. 

This means that such systems fall outside the requirements to be regulated by NRC as nuclear reactors, as they do not involve special nuclear material (plutonium, uranium-233 or enriched uranium) and cannot produce the self-sustained neutron chain reaction that defines nuclear fission reactors under NRC regulations.

In response to this policy, Tennessee, which is an NRC Agreement State, meaning it is authorized to license and inspect byproduct, source, or special nuclear materials used or possessed within its borders under a special agreement with the NRC. The state filed an amendment to its regulations setting out the framework for how it will register and license fusion machines, processes, and related activities.

Chapter 0400-20-14 of the Effective Rules and Regulations of the State of Tennessee, as well as its associated definitions, establishes requirements for the licensing of fusion machines and fusion-related activities in the state. The new regulations came into effect on 06/09/26.

“Tennessee has been named the top state in the nation for nuclear energy industry growth, and for good reason,” said Tennessee Department of Environment and Conservation (TDEC) Commissioner David Salyers. 

“This latest step supercharges our reputation as the global hub for nuclear innovation and positions us as the most responsive state to new advanced nuclear companies clamouring to call Tennessee home.”

Type One Submits Its First License Application for a Fusion Power Plant

In January 2026, US fusion energy developer Type One Energy submitted an initial licensing application in preparation for the construction of a fusion power plant at Tennessee Valley Authority’s (TVA) former Bull Run fossil plant site in Clinton, TN. Type One Energy said it worked closely with the Tennessee Valley Authority (TVA) and the Tennessee Department of Environment & Conservation (TDEC) to prepare the “first-of-a-kind application” for a byproduct material licence, “demonstrating compliance with key licensing requirements for fusion energy technology as part of a comprehensive application process.”

The company’s commercial site near Oak Ridge is anticipated to be among the first licence under this new framework and will function as a fusion development campus through projects between the Oak Ridge National Laboratory, TVA and the University of Tennessee.

TDEC said construction of Type One’s Infinity Two – a 350 MWe baseload power plant using stellarator fusion technology – could begin in 2028 under the new regulatory rules.

About the Type One Fusion Project at TVA

TVA has issued a Letter of Intent (LOI) to Type One Energy regarding the utility’s interest in the potential deployment of Type One Energy’s fusion power plant technology at its former Bull Run Fossil site once it is commercially ready. The LOI also covers potential future use of the prototype facilities as an operator and maintenance training facility for the Infinity Two workforce.

Tennessee Valley Authority (TVA) and Type One Energy have expanded their cooperative agreement to develop a 350 MWe fusion pilot power plant called “Infinity Two” at TVA’s former Bull Run Fossil Plant near Oak Ridge, TN, targeting deployment by the mid-2030s. The partnership represents the first commercial contracts signed for a utility-scale fusion power project in the US

It will utilize Type One Energy’s stellarator fusion technology to provide baseload generation capacity. This collaboration positions TVA as the leading U.S. utility in advanced nuclear innovation, addressing growing energy demands from AI and data centers while advancing fusion commercialization timelines.

Infinity Two is a first-generation 350 MWe baseload power plant utilizing Type One Energy’s stellarator fusion technology. According to the press statement by Type One, the stellarator has demonstrated stable, steady-state operation with high efficiency, characteristics which are important for TVA and others in the industry who need to reliably generate on-demand power at competitive prices.

Type One Energy is developing Infinity Two using existing materials and fundamental fusion technologies to support near-term deployment of the technology.

Final decisions and definitive agreements regarding the funding and construction of Infinity Two, as well as any agreements to purchase the energy output, are subject to TVA Board approval, regulatory review, and alignment with TVA’s least-cost planning processes.

Type One’s lead scientist told Knox News in March 2026 that company won’t need a scientific revelation to move the stellarator design forward. As CEO Chris Mowry put it, “This is not a science project.”

“This is an actual commercial fusion power plant that we are embarking on here.”

DOE Approves Xcimer’s Fusion Power Preconceptual Design 

Xcimer Energy announced that the U.S. The Department of Energy (DOE) has formally approved the company’s preconceptual design and technology development roadmap milestone for Athena, Xcimer’s architecture for fusion power plants.

Xcimer’s 724-page submission provided DOE reviewers with a detailed assessment of plant performance targets, economics, system-level engineering requirements, safety and environmental analyses, and technology development pathways required to achieve commercial fusion power.

Athena is the architecture for Xcimer’s fleet of fusion power plants, designed for continuous operation and integrating the company’s proprietary excimer laser platform with target delivery, fusion chamber, tritium breeding, and power generation systems engineered for industrial scale.

This milestone positions Xcimer among the leading companies racing to commercialize fusion energy at industrial scale. The news comes a week after Xcimer began operating Phoenix, the largest privately owned laser system in the world and the company’s prototype for commercializing laser fusion. 

The acceptance of both the design and roadmap also reflects continued progress under the DOE’s Fusion Milestone Development Program, The firm said in its press statement that the decision “validates Xcimer’s roadmap for translating laboratory fusion breakthroughs into a commercially deployable energy system.”

Athena is the reference architecture for Xcimer’s fleet of fusion power plants. Designed for continuous operation, Athena integrates the company’s proprietary excimer laser platform with target delivery, fusion chamber, tritium breeding, and power generation systems engineered from the outset for industrial scale.

Conner Galloway, CEO, Chief Science Officer, and co-founder of Xcimer Energy, said, “The question facing laser fusion is no longer whether the physics works, the question is how fast we can industrialize it.”

The milestone comes a week after Xcimer announced the launch of operations of its prototype laser system, code-named Phoenix – the largest privately owned laser system in the world and the company’s prototype for commercializing laser fusion. (See story below)

Phoenix, housed in Xcimer’s 74,000-square-foot Denver laser facility, is a proof of concept for an unconventional fusion architecture: a krypton fluoride (KrF) excimer laser using Stimulated Brillouin Scattering (SBS) to compress a microsecond-long pulse into the nanosecond timescales fusion requires. Phoenix is designed to demonstrate end-to-end integrated operation of excimer amplification and SBS pulse compression. 

& & &

Xcimer Energy Starts of Operations of a Prototype System for Industrial-Scale Laser Fusion

Xcimer Energy announced the start of operations for Phoenix, the largest privately owned laser system in the world and the company’s prototype for commercializing laser fusion.

Phoenix demonstrates end-to-end integrated operation of excimer amplification and SBS pulse compression. The light source for Phoenix operates at pulse energies over 1 kJ, and the SBS gas optic at the core of Phoenix is 38 meters long. This is the highest-ever energy and largest spatial extent of SBS in an optical system.

Designing, building and operating Phoenix required Xcimer to rebuild industrial capabilities around large-scale electron-beam-pumped excimer lasers – a competence that was in danger of disappearing after the Cold War.

The U.S. Naval Research Laboratory, which built and operated the only two remaining large-scale KrF excimer laser systems in the United States, preserved critical technical knowledge that helped bridge the gap between earlier government programs and today’s renewed commercial efforts.

“We had to rebuild an industrial capability the United States largely abandoned after the Cold War, restoring specialized supply chains, recruiting many of the last engineers with direct experience in these systems, and transferring that knowledge to a new generation,” said Conner Galloway, co-founder and CEO of Xcimer. 

“Phoenix represents both a technical milestone and the reindustrialization of high-energy excimer lasers in America.”

The Physics and the Economics

Laser fusion is the only fusion approach to achieve scientific breakeven in a laboratory. In 2022, the National Ignition Facility (NIF) demonstrated net energy gain from fusion, and in 2025 produced 8.6 megajoules of fusion energy from 2 megajoules of laser input.

NIF was built as a scientific research facility, not a commercial power plant. Its solid-state glass laser architecture is too expensive, complex, and maintenance-intensive for economical grid-scale electricity generation.

Xcimer believes commercial fusion requires a fundamentally different industrial system. Its krypton fluoride excimer lasers are designed for higher efficiency, fewer beamlines, lower thermal stress, and compatibility with industrial-scale manufacturing. The architecture uses two beamlines rather than NIF’s 192 and is designed to reduce operational complexity and maintenance requirements.

“NIF proved laser fusion physics works,” said Xcimer co-founder and President Alexander Valys. 

“Our thesis is that commercial laser fusion becomes possible only if the laser system itself becomes dramatically simpler, cheaper, and more manufacturable.”

What Comes Next?

Phoenix is the first step in Xcimer’s roadmap toward commercial fusion energy.

• Anvil (2028): Commercial-scale excimer amplifier delivering 200 kilojoules on target in a complete two-sided beamline.
• Vulcan (early 2030s): 4–12 megajoule laser system targeting wall-plug breakeven and supporting high-energy-density and national-security applications. Xcimer expects to select a Vulcan site this year.
• Athena (mid-2030s): Commercial-scale laser fusion power plant designed for continuous grid-scale electricity generation.

About Xcimer

Founded in 2022 the founders are Conner Galloway (CEO), Alexander Valys (President & CTO) with company HQ in Denver, CO. The team consists of about 150 people across engineering, physics, operations, and manufacturing. 

Funding: More than $150M raised from energy and technology investors, including Breakthrough Energy Ventures, Lowercarbon Capital, Emerson Collective, Prelude Ventures and many others. Xcimer received the largest laser fusion award from the U.S. Department of Energy’s Milestone-Based Fusion Development Program.

Romania Weighs Investing in PHWR Upgrades Over SMRs

• Cernavoda nuclear plant upgrade is seen as more feasible than the NuScale SMR project in Doicesti 
• Completing Ceravoda Units #3 &4, 700 MW PHWRs, is a priority

(Balkan Green) Romania’s state-owned Nuclearelectrica has approved the final investment decision for a 462 MW nuclear power plant with small modular reactors (SMR). However, it turns out Prime Minister Ilie Bolojan may be having a case of buyer’s regret. He does not expect the SMR project to be completed any time soon, given its high estimated cost and complexity. The curent target date is the mid-2030s. He also believes that the ongoing modernization and expansion of the Cernavoda nuclear power plant is more feasible.He also wants to finish Cernavoda Units #3 & #4 which are partially built 700 MW PHWRs.

Bolojan said that Romania should focus on the ongoing investment projects at the Cernavoda nuclear power plant, which include the refurbishment of unit 1, estimated at over EUR 3.5 billion, and the construction of units 3 and 4, worth about EUR 7 billion.

Bolojan said in interviews with Romanian business news media that an “immediate investment” in the SMR facility in Doicesti is unlikely given the large amount of money that needs to be secured, the complexity of such projects, and the fact that it is still in initial phases. The SMR project in Doicesti would cost up to $7 billion. The facility is planned for construction on the site of a former coal-fired power plant.

“Such investments take five to six years,” Bolojan told Europa FM, as reported by Profit.ro as reported by Balkan Green

He noted that the project at Cernavoda, Romania’s only nuclear power plant, is based on PHWR technology that Romania has operated for years, adding that he believes it is “more feasible than this new type of investment.”

Completion of Units #3 & 4 would give Romania three 700 MW PHWRs which have common technology and offer economies of scale, cross training of personnel, and postponement of costly new capabilities that woukld come with the SMR project.

The overhaul of Cernavoda’s unit 1 was launched in September 2025 by an international consortium led by South Korean state-owned Korea Hydro & Nuclear Power Co. (KHNP). The refurbishment will extend the operating life of the 700 MW reactor by 30 years.

BN-1200 Targeted for Construction Start in 2027

(NucNet) The sodium-cooled BN-series fast reactor plans are part of Rosatom’s project to develop fast reactors with a closed fuel cycle whose mixed-oxide (MOX) fuel will be reprocessed and recycled. 

This is essentially a demonstration unit for fuel and design features for the larger BN-1200, which will be unit 5 at Beloyarsk. The project had previously been postponed several times due to uncertainties related to design issues and costs.

The BN-1200 will join the BN-600 reactor at Beloyarsk unit 3, which began operation in 1980, the 789 MWe BN-800 fast reactor at Beloyarsk unit 4 entered commercial operation in October 2016. Two BN-600 reactors were built in China as the CFR-600 and are expected to burn MOX fuel derived from reprocessing spent fuel from China’s fleet of light water reactors.

Details of the proposed construction timelines came during a visit to the site by Rosenergoatom CEO Alexander Shutikov. Site preparation for drilling and blasting operations and site planning are scheduled to be ready this summer, reported Yuri Nosov, director of the power plant. Shutikov said  the target for first concrete was by the end of 2027.

“Our primary focus now is completing the design documentation for submission to the Main Directorate of State Expertise of Russia, with the goal of receiving a conclusion on the design documentation for the main construction period by the end of 2026. The next step is to obtain a license to construct the power unit in the spring of 2027.”

Rosatom says the service life of the BN-1200 power unit will be at least 60 years. Its design uses technical solutions that have proven themselves in the operation of the BN-600 and BN-800 reactors, but also features innovations.

For example, the BN-1200 will have four instead of three loops for the circulation of liquid sodium, like its predecessors; the volume of the in-reactor storage facility will be increased to allow the unloading of fuel assemblies from the reactor directly into the used fuel pool, eliminating the intermediate drum for used assemblies; and the turbine condensers will be cooled using a chimney-type evaporative cooling tower.

In April last year Russia’s nuclear regulator Rostechnadzor gave the go-ahead for the BN-1200 reactor. The licence was issued after the consideration of a package of documents covering the safety of the power unit and its compliance with technical regulations, federal rules and standards and legislation, Rosatom said.

It says that the fourth generation units “have the potential to radically transform the nuclear energy industry, primarily through a new level of safety, an expanded fuel mix, and a significant reduction in radioactive waste” and contributing to a closed nuclear fuel cycle.
