Under the agreement with NNE, Hyundai Engineering plans to support the KRONOS micro modular reactor project at the University of Illinois Urbana-Champaign campus. The project aims to provide heat for the campus and advance its carbon neutrality goals.

The companies will explore engineering, procurement and construction (EPC) opportunities for auxiliary reactor facilities, modular design reviews, supply chain development and business planning. NNE, headquartered in New York and listed on Nasdaq, is developing a high-temperature gas-cooled microreactor.

Partnership Covers ARC-100 Reactor Deployment

Hyundai Engineering has also signed an MOU with ARC Clean Technology to explore cooperation on the first deployment of the ARC-100, a 100-megawatt electric sodium-cooled fast reactor.

ARC is pursuing a commercial demonstration plant at Idaho National Laboratory, with an initial capacity of approximately 200 megawatts and potential expansion to 600 megawatts, according to Hyundai Engineering.

Hyundai Engineering’s Nuclear Experience

Hyundai Engineering said its nuclear engineering experience spans more than four decades and includes 254 nuclear-related projects involving operating reactors, fuel facilities, research reactors and SMR technology.

The company also reported holding approximately 31% of the contract value in competitive nuclear design service bids commissioned by Korea Hydro & Nuclear Power over the past six years.

Its international work includes upgrades to research reactor facilities at Delft University of Technology in the Netherlands and an initial design and consulting contract for a next-generation research reactor at the University of Missouri.

A Hyundai Engineering official said the agreements would expand the company’s capabilities across the project cycle, from design through engineering, procurement and construction, and strengthen its position as a partner in the global SMR market. The Hyundai Engineering SMR initiatives build on the company’s experience across nuclear engineering and project development.

The reforms form part of the government’s ambition to quadruple nuclear power output to 24 GW by 2050. Electricity demand in Britain is forecast to rise by 40% by 2035, according to the National Energy System Operator, increasing the importance of reliable electricity generation.

The Office for Nuclear Regulation (ONR), Environment Agency (EA) and Natural Resources Wales (NRW) aim to reduce reactor design approval periods from approximately three or four years to around two years. The changes follow the 2025 Nuclear Regulatory Review, which identified fragmented oversight, costly regulatory decisions and complex legislation as obstacles to nuclear development.

The review made 47 recommendations, including improved coordination between regulators, more proportionate safety assessments and a fleet-based approach that would reduce the need to repeatedly examine identical reactor designs. The government also intends to streamline planning and environmental approvals, which have contributed to lengthy development schedules and high costs.

Holtec SMR Project Could Test Regulatory Cooperation

Holtec’s proposed SMR-300 deployment in the UK could provide an early test of whether regulatory cooperation between Britain and the United States can reduce approval times.

UK authorities have identified the company’s two-unit SMR-300 project at Palisades in Michigan as the reference design for its UK Generic Design Assessment (GDA). The GDA evaluates a reactor design’s safety, security and environmental acceptability independently of a specific site.

Holtec submitted its Preliminary Safety Analysis Report for Palisades to the U.S. Nuclear Regulatory Commission (NRC) on 30th September 2026. The company intends to use the U.S. design and safety analysis in Britain.

“Our intention is to apply the U.S. design and safety analysis in the UK,” said Patrick O’Brien, Executive Director, Government Affairs and Communications at Holtec International.

Holtec completed Step 2 of the GDA for its SMR-300 in March 2026. The company plans to deploy up to four units with EDF and Tritax at Cottam, a former coal-fired power station in Nottinghamshire, England. The proposed development would provide around 1.3 GW of generating capacity.

Reusing design and engineering work from Palisades could help reduce first-of-a-kind engineering risks and improve schedule and cost predictability. However, the extent to which UK regulators will accept assessments completed by the NRC remains a key factor in determining the potential benefits.

U.S. Reactor Designs Enter UK Assessment Process

Several other U.S. developers are progressing through the British regulatory process. Westinghouse’s 300 MW AP300 reactor entered the GDA process in August 2024. TerraPower’s Natrium reactor formally began its GDA application process in June 2026, while X-energy’s Xe-100 entered the process in September.

TerraPower has not selected a site for its first UK deployment. The company has said the project would represent the first Natrium reactor outside the United States.

X-energy said the GDA remains a rigorous assessment covering safety, security, safeguards and environmental acceptability. Its generic approach allows developers to establish whether a design is acceptable before incurring significant site-specific expenditure.

The company sees similarities with the NRC’s standard design certification process, which allows projects to rely on technology-level assessments rather than repeat every design review. X-energy is working with the ONR and NRC to map U.S. assessments against UK requirements.

A policy introduced by the ONR, EA and NRW in May 2026 provides a framework for the regulators to use assessments conducted by trusted overseas regulatory bodies.

X-energy has selected Centrica as its partner to develop up to 6 GW of advanced nuclear capacity in Britain. The proposed initial development is a 12-reactor, 960 MW project at Hartlepool in northeast England. Centrica owns 20% of Britain’s operational nuclear fleet and holds a 15% stake in the 3.2 GW Sizewell C project in Suffolk.

UK Government Support for Domestic SMR Development

U.S. developers will face competition from Britain’s domestic nuclear programme. Great British Energy-Nuclear has contracted Rolls-Royce SMR to deliver three reactors with a combined generating capacity of 1.4 GW at Wylfa, a former nuclear site on Anglesey in North Wales. The site could eventually accommodate eight units.

Initial work at Wylfa is due to begin in 2026, with the first reactor expected to become operational in the mid-2030s. The UK government has committed more than £2.5 billion to its wider SMR programme, which includes the Wylfa development.

Rolls-Royce SMR also has an established domestic supply chain. The company has spent more than £300 million with suppliers since 2021, with at least 70% of that spending going to UK businesses.

Holtec is evaluating the business case for a UK factory that could serve as a regional component manufacturing hub. Westinghouse signed agreements with six British suppliers in September 2025 to support the construction of AP1000 and AP300 reactors in the UK and other markets.

Stewart Forbes, Counsel at Hogan Lovells Cadwalader said, “The economics of SMRs depend on repeat production and standardisation.” U.S. developers may benefit from their larger domestic market and international manufacturing networks, while Britain’s support for pressurised-water SMRs and Generation IV advanced modular reactors could create opportunities for several reactor designs.

The outcome will depend on how effectively the UK implements its proposed nuclear regulation changes and whether regulators can recognise relevant overseas assessments without compromising safety and environmental standards.

The proposed project is planned for Sinop, in Turkey’s Black Sea region. AtkinsRéalis Chief Executive Officer Ian Edwards said in a LinkedIn post that the company would conduct a feasibility study to advance the potential construction of CANDU reactors at the site.

The development follows an agreement between Canada and Turkey to strengthen their strategic partnership, including cooperation in energy, defence, security, trade and investment. Carney said the Turkish government would make the final decision on the nuclear project, but he believes Canada’s prospects have improved.

AtkinsRéalis Explores CANDU Technology for Sinop

Turkey has held discussions with several countries about its planned second nuclear power plant, including Canada, South Korea, Russia, China and Japan. The proposed facility is planned for Sinop, where AtkinsRéalis is exploring the potential application of its CANDU reactor technology.

Speaking to reporters in Istanbul, Carney said there was active competition for the project and suggested a decision could be made before the end of 2026.

He highlighted Canada’s nuclear technology, partnerships with Turkish businesses and potential to develop elements of the supply chain as factors supporting its proposal.

“If you would have asked us a year ago how we would have pegged the chances, they would have been very low. Now there are good chances. There’s real competition, of course,” Carney said.

The feasibility study is an early step in assessing the potential project. The announcement does not confirm a construction contract, a final technology selection or a construction schedule for the proposed plant.

Canada and Turkey Strengthen Nuclear Energy Cooperation

The nuclear discussions form part of a broader effort by Canada and Turkey to expand economic and strategic cooperation. During Carney’s visit to Ankara, the two NATO allies upgraded their bilateral relationship to a strategic partnership, with energy identified as one of its principal areas of cooperation.

The agreement aims to create further opportunities for Canadian and Turkish businesses through expanded trade and investment. The countries also announced plans to increase collaboration across the energy sector, including civil nuclear energy, liquefied natural gas (LNG) and renewable energy.

For AtkinsRéalis, the potential Sinop project would provide an opportunity to explore the use of Canadian CANDU technology in Turkey’s nuclear power development programme. Carney also pointed to cooperation with Turkish companies in construction and the potential to establish supply-chain links as elements of Canada’s proposal.

Turkey’s government will ultimately determine which partner or technology is selected for the second nuclear power plant. The country has been considering proposals from several international participants, and the feasibility study does not guarantee that AtkinsRéalis will be selected.

Turkey’s Nuclear Programme Includes Multiple Planned Plants

Turkey is pursuing nuclear power development at several locations. Its first nuclear power station is under construction at Akkuyu, in the Mediterranean province of Mersin, by Russia’s state-owned nuclear energy company Rosatom.

The Akkuyu project is being developed under a USD 20 billion agreement signed in 2010. Rosatom said in October 2026 that it expected a nuclear start-up at the site by the end of the year.

Beyond Akkuyu, Turkey plans a second nuclear power plant at Sinop and a third in the northwestern region of Thrace. The potential involvement of AtkinsRéalis in Sinop remains under consideration as Turkey engages with international partners.

The selection of a technology provider and project partner will be a significant step in determining how the second plant proceeds. At present, the AtkinsRéalis feasibility study represents progress in evaluating the CANDU option, rather than confirmation that construction will go ahead with the Canadian company.

Feasibility Study Precedes a Final Project Decision

Carney said the Turkish government would make the final decision on the second nuclear power plant and noted that competition from other international suppliers remains strong. He nevertheless expressed greater confidence in Canada’s position following the strategic partnership agreement.

AtkinsRéalis has identified the Sinop site as the focus of its feasibility work for potential CANDU reactor construction. The study is intended to advance consideration of the technology, while the broader bilateral agreement creates a framework for further cooperation in civil nuclear energy and other sectors.

No final contract, investment amount or construction timetable for the Sinop plant was announced in the report. The next major milestone will be Turkey’s decision on the project and the technology and partners it chooses to pursue.

The development of nuclear fuel manufacturing is intended to strengthen the domestic nuclear fuel supply chain, support the existing US reactor fleet and enable the wider deployment of advanced nuclear technologies. Westinghouse described the facility as the first fleet-scale nuclear fuel factory built in the United States in more than 50 years.

The investment also aligns with the US government’s efforts to restore domestic nuclear fuel capabilities and meet rising demand for reliable, low-carbon baseload electricity.

New Facility to Expand LEU+ Fuel Production

The new Columbia factory will manufacture LEU+ fuel, which uses uranium enriched to between 5% and 8%. This enrichment range is higher than that of conventional low-enriched uranium fuel used in many commercial reactors.

According to Westinghouse, LEU+ fuel could allow eligible nuclear power plants to extend operating cycles and pursue power uprates, subject to reactor-specific technical assessments and regulatory approvals. These capabilities could help operators increase electricity output, improve operating flexibility and reduce certain operating costs.

The company said the new facility builds on the first successful deployment of LEU+ fuel in the United States in 2025. Expanding production capacity is intended to move the technology toward broader commercial availability.

Westinghouse also expects the fuel to support the long-term operation of existing nuclear plants and the deployment of its AP1000 reactor technology internationally.

Investment Supports US Nuclear Energy Expansion

The project is aligned with the United States’ UPRISE program, which seeks to support increased nuclear generation from the existing reactor fleet. By expanding fuel manufacturing capacity, Westinghouse aims to help utilities access the fuel needed to support higher output from eligible facilities.

US officials have also emphasized the importance of establishing a secure domestic supply chain for nuclear fuel. The Department of Energy is investing in efforts to restore uranium enrichment capabilities for both low-enriched uranium and high-assay low-enriched uranium.

Assistant Secretary for Nuclear Energy Ted Garrish said, “A strong American nuclear industry starts with a secure, domestic supply of nuclear fuel.”

The new factory will provide additional manufacturing capacity to convert enriched uranium into fuel assemblies and other products used in nuclear reactors. Its development forms part of a broader effort to strengthen domestic nuclear infrastructure and support the next generation of nuclear technology.

South Carolina Facility to Support Jobs and Economic Growth

Westinghouse’s Columbia Fuel Fabrication Facility was built in 1968 and is one of the world’s largest nuclear fuel plants. It manufactures fuel pellets, rods, assemblies and components for Westinghouse facilities and customers worldwide.

The site currently employs more than 1,200 people in Lower Richland, South Carolina. The expansion is expected to create additional employment opportunities through construction, equipment installation, workforce development and long-term manufacturing operations.

An economic impact study commissioned by Westinghouse in partnership with researchers at the University of South Carolina’s Darla Moore School of Business estimates that the investment could generate US$4.9 billion in positive economic impact across South Carolina over the next decade. Of that amount, approximately US$3.8 billion is projected to benefit Richland County.

“South Carolina is already leading America’s nuclear renaissance, and our state has been producing the nuclear fuel that powers approximately 10% of the United States from Westinghouse’s fuel operations in Richland County,” said South Carolina Governor Henry McMaster. “We are grateful for Westinghouse’s continued leadership in South Carolina, and we look forward to it expanding its work in our state to create next-generation fuel products that will continue to support nuclear energy production well into the future.”

Congressman James E. Clyburn added, “This investment is a testament to our state’s skilled workforce and the important role we play in strengthening America’s clean energy. By expanding our domestic nuclear fuel production capabilities, we are creating economic opportunities, supporting good-paying jobs and positioning South Carolina as a leader in the nation’s energy sector.”.

Construction Underway Ahead of 2030 Operations

Construction of the new LEU+ fuel manufacturing building is underway, with Westinghouse targeting the start of operations in 2030. The company said support from the US Department of Energy’s tax credit program, state authorities and Richland County helped advance the investment.

Westinghouse has also stated that the project will incorporate environmental stewardship measures, including responsible site development and preservation of native landscapes that support wildlife habitats and local air and water resources.

Once operational, the facility is expected to increase US capacity to manufacture advanced nuclear fuel. The expansion will be an important step in Westinghouse’s plans to support existing reactors, enable potential increases in nuclear generation and supply fuel for future reactor deployments.

The companies announced a joint development agreement on 19 October covering the proposed advanced nuclear plant at the former Breed Generating Station. The site was previously operated by Indiana Michigan Power, an AEP subsidiary. The agreement covers development and feasibility work, but the companies have not announced a construction start date or a project cost estimate.

Xe-100 Reactors Planned For Indiana Site

The proposed facility would use 12 Xe-100 small modular reactors developed by X-energy. The reactors would be arranged in three groups of four, with each group designed to produce 320 MW, bringing the planned generating capacity to 960 MW.

The Xe-100 is a high-temperature, helium-cooled pebble-bed reactor rated at approximately 80 MW of electricity per unit. The proposed deployment would represent the second project under the collaboration between Amazon and X-energy, which aims to support more than 5 GW of new nuclear capacity across the United States by 2039, World Nuclear News reported.

Amazon’s development contribution is structured around project milestones. If the facility is constructed and begins commercial operations, Amazon would purchase its electricity through a long-term agreement intended to cover the facility’s costs and operations.

AEP chairman, president and chief executive Bill Fehrman said the agreements carry “all necessary capital protections and financial safeguards that we have said are essential for any potential nuclear project to move forward.”

Josh Weissman, Amazon’s vice president of data center infrastructure capacity delivery, said, “We’re looking to develop nearly a gigawatt of carbon-free power for the regional grid and pay our full costs without passing them to others.”

Rising Electricity Demand Supports Nuclear Plans

The Indiana proposal follows Amazon’s 30 September agreement with Constellation Energy for a 20-year, 690 MW power purchase agreement associated with Maryland’s Calvert Cliffs nuclear plant expansion. The latest project adds to Amazon’s efforts to secure long-term electricity supplies as demand from data centers increases.

Indiana Michigan Power has told regulators that peak electricity demand in the state could exceed 7,000 MW by 2030, compared with 2,800 MW, as large electricity users connect to the grid. Indiana also approved large-load interconnection rules last year under a pact filed by the utility with Amazon Data Services, Google, Microsoft and other parties.

Sullivan County participates in Indiana’s Advanced Nuclear Ready Communities Program, which identifies counties that have taken steps to accommodate advanced nuclear development. Data center directory Baxtel tracks 146 facilities operated by 46 providers across Indiana, with Amazon Web Services listed as the state’s largest operator, with 33 sites.

The proposed advanced nuclear plant remains in the feasibility stage. X-energy and AEP have not disclosed a construction timeline or estimated investment, and the project must progress beyond development work before the planned generating capacity can be delivered.

The agreement establishes an initial evaluation rather than a commitment to construct the reactors. According to the memorandum, any project timeline “will depend on site selection, financing, utility or offtake arrangements, applicable regulatory and licensing activities, environmental review, transmission and interconnection planning, community and stakeholder engagement, and other diligence and approvals”.

Candu Technology And Deployment Options

The partners will assess potential deployment scenarios for Candu nuclear technology and consider a gas-to-nuclear construction model intended to accelerate the addition of new generating capacity. This approach could include locations where existing power facilities have been retired or are approaching retirement.

Indiana Governor Mike Braun said: “Ensuring affordable electricity and high-wage opportunities for Indiana’s skilled workforce are top priorities. By exploring this technology, we’re evaluating a path to deliver more affordable power while creating the kind of long-term, skilled jobs that strengthen Hoosier communities.”

Candu reactors use heavy water, or deuterium oxide, as a moderator and coolant, and are designed to operate using natural uranium fuel. The technology has been deployed in Canada, Romania, Argentina, South Korea and China. According to the information provided by the project partners, approximately 34 units have been built internationally.

AtkinsRéalis is the original equipment manufacturer and exclusive licence holder for Candu technology. The company’s Enhanced Candu 6 design is a pressurised heavy water reactor in the 700 MW-plus class. It uses natural uranium fuel and online refuelling, allowing the reactor to continue operating while fuel is replenished.

Joe St Julian, president of Nuclear at AtkinsRéalis, said: “This collaboration demonstrates the value of working with our American partners to address shared energy challenges and exploring solutions that strengthen energy security, support skilled jobs and deliver lasting benefits to communities in the state.”

Hoosier Energy President and CEO Donna Walker said: “Through this MOU, Hoosier Energy is pleased to offer our expertise as part of early discussions to evaluate whether advanced nuclear energy could be an option worth considering.”

US Licensing Work And Indiana Nuclear Plans

AtkinsRéalis submitted a Notice of Intent to the US Nuclear Regulatory Commission in June 2026 to begin the licensing process for its technology in the United States. The first public NRC meeting associated with the process took place in August 2026, and the company has submitted the first of seven planned topical reports, covering its quality assurance programme.

The proposed Candu nuclear project comes as other developers assess new nuclear capacity in Indiana. Earlier, American Electric Power, X-energy and Amazon announced a separate feasibility study for a proposed 960 MW advanced nuclear facility at the former Breed Generating Station in Sullivan County.

Both proposals remain at an early stage. The 6 GW initiative will require further evaluation of technical, commercial, regulatory and site-related conditions before the partners can determine whether to proceed with construction.

The connection took place while the reactor was operating at 20% of its design power, according to the company. Mochovce-4 has an installed electrical capacity of 471 MW and is expected to produce approximately 3.5 TWh of electricity annually once fully operational. This would represent around 13% of Slovakia’s current electricity consumption.

Commissioning Continues With Further Testing

The grid connection followed inspections and tests of generator protection systems, electrical circuits and equipment required to transmit electricity. Slovenské Elektrárne said the next steps involve synchronising the second turbine generator and conducting additional tests as reactor power increases.

The remaining commissioning programme will assess technological, control and safety systems at progressively higher power levels, including at nominal capacity. Slovakia’s nuclear regulator continues to supervise the process to ensure the unit meets the necessary requirements before entering full commercial operation.

Construction History and Reactor Specifications

The Mochovce-4 reactor reached first criticality on August 6, 2026, after fuel loading was completed in June. The unit uses a VVER-440/V-213 pressurised water reactor design.

Construction of Mochovce-3 and Mochovce-4 began in 1987, but work was suspended in 1991 because of funding difficulties. Development resumed in 2008, eventually leading to the commissioning of the two units at different times. Mochovce-3 connected to the national grid in February 2023 and completed commissioning later that year.

Nuclear Power Maintains a Major Role in Slovakia

Slovakia operates five nuclear reactor units across two sites: three at Mochovce and two at Bohunice. According to data from the International Atomic Energy Agency, the country’s nuclear fleet generated approximately 65% of its electricity in 2025.

The addition of the Mochovce-4 reactor is expected to strengthen Slovakia’s domestic electricity generation capacity. Its projected annual output of 3.5 TWh would make a substantial contribution to national electricity supply once commissioning is complete and the unit reaches full operation.

Rosatom announced the agreement on October 19, following its signing with Indonesian state-owned company PT Pembangkit Listrik Nuklir on October 16 during Russian Energy Week in Moscow. Under the arrangement, Rosatom will provide two FPU-100 floating power units with a combined capacity of 200 MW. The proposed installations would be located in Indonesian waters around 3,000 kilometres from Kuala Lumpur and 1,400 kilometres from Kota Kinabalu.

The company said “The FPUs are expected to begin supplying their first megawatts of electricity to consumers in Indonesia as early as five years after the key terms of the electricity supply contract come into effect.” Rosatom Director General Alexey Likhachev said, “Rosatom is ready to offer the most advanced and proven technological solutions available on the global market.”

Indonesia Strengthens Its Long-Term Nuclear Energy Plans

Indonesia included nuclear power in its National Energy Plan in 2025, identifying it as an instrument for long-term energy security and its goal of carbon neutrality by 2060. The agreement for floating nuclear plants represents a step in the country’s plans to incorporate nuclear generation into its future energy mix, although the facilities remain several years from expected operation.

Malaysia Resumes Assessment of Nuclear Power Options

Malaysia has also resumed preliminary work on nuclear energy. The country restarted Phase 1 of the International Atomic Energy Agency’s Milestones Approach to assess the feasibility of adding nuclear power to its national grid. Its earlier programme lost momentum after a change of federal government following the May 2018 general election, when the Malaysia Nuclear Power Corporation was disbanded.

In November 2024, responsibility for charting a possible path towards nuclear power was assigned to the Malaysia Programme Office for Power Electricity Reform (MyPOWER) Corporation, a special-purpose agency under the Energy Transition and Water Transformation Ministry. The ministry is overseen by Deputy Prime Minister Datuk Seri Fadillah Yusof.

Small Modular Reactor Development Continues Worldwide

Rosatom estimates that approximately 80 small modular reactor projects are currently at the design stage worldwide. The Indonesian agreement adds to regional interest in nuclear technology as governments assess options for long-term electricity supply and lower-carbon energy systems.

The seventh cascade is expected to be installed later in 2026, followed by the final unit in spring 2027. Alongside the new installations, Urenco USA plans to begin refurbishing existing cascades in 2027 to maintain the facility’s operational reliability and support a sustained supply of enrichment services to its customers.

The company has outlined another major development phase, with construction of a new enrichment plant scheduled to begin in 2029. The proposed facility will provide an additional 2.1 million SWU of capacity. Production from the initial cascades is expected to start in 2032, while further cascades will be installed through 2036. These projects form part of Urenco USA’s strategy to expand its enrichment capabilities for the nuclear industry.

Jody Blackshear, Managing Director of Urenco USA said, “We are consistently delivering new capacity to help fuel the US nuclear industry and allied nations, and our teams are doing it ahead of schedule and on budget.”

“This experience will support our larger capacity programmes in the years ahead as we look to increase our enrichment production by more than 50% to meet the needs of our customers with traditional and advanced reactors,” he added.

Uranium enrichment increases the concentration of uranium-235, the isotope capable of undergoing fission in a nuclear reactor. Naturally occurring uranium contains approximately 0.7% uranium-235, whereas most commercial nuclear reactors currently require fuel containing between 3.5% and 5% of the isotope. The process involves passing gaseous uranium hexafluoride through centrifuges, which separate isotopes using their slight differences in mass.

Located in Eunice, New Mexico, the Urenco USA National Enrichment Facility is currently the only commercial uranium enrichment facility in the United States. The expansion is intended to strengthen the company’s ability to supply enrichment services as demand from conventional and advanced reactor technologies grows.

The financing expands the industrial coalition supporting Helical Fusion’s development roadmap, which targets commercially viable fusion power in the 2030s. Other investors in the second close include HAZAMA ANDO CORPORATION, Fujikura Ltd., TOKYO GAS CO., LTD., KKT LLC, URATA Co., Ltd., Ecrowd NEXT and Kepple Group, Inc.

Including grants and loans, Helical Fusion’s cumulative funding has reached approximately JPY 13.15 billion. The company said the latest capital will accelerate development toward integrated demonstration with Helix HARUKA and subsequent net-electricity generation with Helix KANATA, its first fusion power plant.

Fuji Electric Expands Industrial Collaboration

Fuji Electric brings capabilities in power electronics, power generation, energy infrastructure, industrial systems, instrumentation and control, and nuclear-related technologies. Its participation expands the expertise supporting the development of fusion power systems.

The companies began working together in 2025, when Fuji Electric agreed to supply power supply equipment for Helical Fusion’s high-temperature superconducting magnet development. Under the new capital and business alliance, their collaboration will expand toward products, services and advanced technologies for future fusion power systems.

Fuji Electric has also joined the Helix Program Official Partners, established in April 2026 for companies making strategic business and significant capital commitments to fusion power development.

Helix HARUKA Construction Advances

Construction of Helix HARUKA, Helical Fusion’s Integrated Demonstration Device, is progressing at the National Institute for Fusion Science campus in Toki City, Gifu Prefecture. The device is designed to integrate and demonstrate technologies including high-temperature superconducting magnets and blanket systems.

More than 30 Japanese companies are contributing to its development and manufacturing. The project combines NIFS research capabilities, Japanese government support, industrial manufacturing expertise and Helical Fusion’s system integration.

Helix Program Targets Commercial Fusion

The Helix Program is Helical Fusion’s roadmap toward commercially viable fusion power using the Helical Stellarator. Its development is guided by continuous operation, net electricity and high maintainability.

Helical Fusion aims to demonstrate core high-temperature superconducting magnet and blanket/divertor technologies by the end of the 2020s. Integrated demonstration with Helix HARUKA and net-electricity generation through Helix KANATA are targeted for the 2030s.

The company was founded in 2021 as a spin-out based on research originating from Japan’s National Institute for Fusion Science. Japan has developed the Helical Stellarator approach for approximately 70 years, with NIFS’s Large Helical Device providing extensive research and engineering experience.

Helical Stellarator Research Foundation

NIFS’s Large Helical Device, one of the world’s largest superconducting stellarator-type experimental devices, has accumulated extensive scientific and engineering knowledge. Its achievements include plasma operation lasting 3,268 seconds, or approximately 54 minutes, and plasma temperatures exceeding 100 million degrees Celsius.

Helical Fusion is building on this research foundation while developing the engineering systems needed to advance the Helical Stellarator from a research platform toward a power generation system.

Takaya Taguchi, Co-Founder and CEO of Helical Fusion commented, “The Helix Program is steadily moving forward. At the Helix HARUKA construction site, our team and industrial partners are working together every day to turn fusion technology into real hardware.

The participation of Fuji Electric and other leading companies across Japan’s energy and industrial sectors further strengthens the foundation for building a new energy industry. Fusion requires capabilities across power electronics, materials, manufacturing, power generation systems and many other fields, and bringing them together is exactly what the Helix Program is designed to do.

Japan has accumulated nearly 70 years of knowledge in Helical Stellarator research and has one of the world’s strongest manufacturing and engineering ecosystems. We intend to bring these strengths together to realize commercial fusion power and create a new global energy industry.”
