Centrica and X-energy Sign Joint Development Agreement to Deploy U.K.’s First Advanced Modular Reactors and Pursue 6 Gigawatts of New Nuclear Capacity in the U.K.

• Preferred first project is expected to be at EDF and Centrica’s Hartlepool site, paving the way for a national fleet of up to 6 GW of advanced reactors with the ability to provide enough power for 14 million homes. 

• Fleet deployment target is the largest announced to date for Advanced Modular Reactors in the U.K. and could generate at least $54 billion in economic activity, creating thousands of high-quality jobs.

•  Deployed new nuclear capacity is set to make a significant contribution to the next wave of clean, secure electricity and high temperature heat for industry and manufacturing.

LONDON, September 15, 2025 – Centrica plc (“Centrica”) and X-Energy, LLC (“X-energy”), a wholly-owned subsidiary of X-Energy Reactor Company, LLC, today announced their entry into a Joint Development Agreement (“JDA”) to deploy X-energy’s Xe-100 Advanced Modular Reactors (“AMR”) in the United Kingdom. The companies have identified EDF and Centrica’s Hartlepool site as the preferred first site for a planned U.K. fleet of up to 6 gigawatts.

The agreement represents the first stage in a new trans-Atlantic alliance which could ultimately mobilize at least $54 billion in economic value to bring clean, safe and affordable power to thousands of homes and industries across the country and substantive work for the domestic and global supply chain. 

A 12-unit Xe-100 deployment at Hartlepool could add up to 960 megawatts (“MW”) of new capacity, enough clean power for 1.5 million homes and over $15 billion in lifetime economic value. It would be developed at a site adjacent to Hartlepool’s existing nuclear power station which is currently scheduled to cease generating electricity in 2028. Following its decommissioning, new reactors would accelerate opportunities for the site and its skilled workforce. The site is already designated for new nuclear under the Government’s National Policy Statement and a new plant would also play a critical role in generating high-temperature heat that could support Teesside’s heavy industries.

Centrica will provide initial project capital for development with the goal of initiating full-scale activities in 2026. Subject to regulatory approval, the first electricity generation would be expected in the mid-2030s. Centrica and X-energy are already in discussions with additional potential equity partners, as well as leading global engineering and construction companies, with the goal of establishing a UK-based development company to develop this first and subsequent projects.

Chris O’Shea, CEO of Centrica said:

 “Centrica is proud to be at the forefront of Britain’s clean energy transition - investing in infrastructure and jobs that meet today’s energy needs while enabling tomorrow’s ambitions.

“Our partnership with Centrica represents a commitment to bring X-energy's industry-leading advanced nuclear technology to the U.K. at scale. Together, we aim to build a fleet that has the ability to reliably deliver clean power, strengthen energy security, and grow the trans-Atlantic economy for decades to come. We believe Hartlepool is the right place to begin this journey, with an established industry and a base of professionals and services who can help drive the next generation of nuclear forward.”

In 2021 the U.K.’s Department of Energy Security and Net Zero (DESNZ) identified High-Temperature Gas-cooled Reactors (HTGRs) as the most promising advanced technology for demonstration. In 2025 X-energy and Cavendish Nuclear completed a number of year-long assessments, co-funded by DESNZ’s ‘Future Nuclear Enabling Fund’, to support the commercial deployment of Xe-100s in the U.K.  Discussions are now underway with Government regarding the “route to market” in the UK, consistent with the principles set out in June for supporting privately led projects. The Government’s ongoing work to create a clear and credible pathway is instrumental in making the UK an attractive destination for investment in advanced modular reactors. Support for initial projects, and those that follow, will be decisive in unlocking the full potential of advanced nuclear for Britain’s energy future.

U.K. Secretary of State for Energy Security and Net Zero Ed Miliband said:

“This cross-Atlantic partnership demonstrates the transformative potential for the British people of US and UK businesses joining forces, with X-Energy and Centrica’s planned first project alone having the potential to create up to 2,500 good, skilled jobs, add £12 billion in economic value and generate enough energy to power 1.5 million homes. By working with the US, we will reap the benefits of this golden age of nuclear, powering British homes with clean, homegrown energy, delivering well-paid skilled jobs and getting energy bills down for good.”

United States Secretary of Energy Chris Wright said:
“With President Trump’s leadership, the United States is ushering in a true nuclear renaissance – harnessing the power of commercial nuclear to meet rising energy demand and fuel the AI revolution. Meeting this demand will require strong partnerships with our allies around the world and robust collaboration with private sector innovators. Today’s commercial deals set up a framework to unleash commercial access in both the U.S. and UK, enhancing global energy security, strengthening U.S. energy dominance, and securing nuclear supply chains across the Atlantic.” 

Simone Rossi, CEO of EDF in the UK, said:

“As part of its role to enable further new nuclear development in the UK, EDF welcomes the interest by Centrica and X-Energy in Hartlepool as the first site to develop this technology, and we will support the development plans as they evolve.” 

X-energy’s pioneering Xe-100 advanced small modular reactor and TRISO-X fuel are among the safest and most reliable clean energy technologies.

Dow and X-energy Submit Construction Permit Application to the U.S. Nuclear Regulatory Commission for Proposed Advanced Nuclear Project in Texas

• Project supported by U.S. DOE’s Advanced Reactor Demonstration Program

• Represents a key milestone toward bringing advanced nuclear energy to fruition in the U.S. 

MIDLAND, Michigan and ROCKVILLE, Maryland – March 31, 2025 – Dow (NYSE: DOW) and X-Energy Reactor Company, LLC (“X-energy”) announced the submission of a construction permit application to the Nuclear Regulatory Commission (“NRC”) for a proposed advanced nuclear project in Seadrift, Texas. 

Dow’s proposed advanced small modular reactor (“SMR”) project is being developed by its wholly-owned subsidiary, Long Mott Energy LLC. The project is focused on providing Dow’s UCC Seadrift Operations manufacturing site (“Seadrift” or the “site”) with safe, reliable, and clean power and industrial steam replacing existing energy and steam assets that are near end-of-life. The project is supported by the U.S. Department of Energy’s (DOE) Advanced Reactor Demonstration Program (“ARDP”) which is designed to accelerate the deployment of advanced reactors through cost-shared partnerships with U.S. industry. 

Since 2018, X-energy, and subsequently Dow, have worked with the NRC through extensive pre-application engagements to demonstrate the unparalleled safety profile of the Xe-100 advanced SMR through its advanced fuel design, passive safety features, and state-of-the-art analysis techniques. This has culminated in a comprehensive application submittal that exceeds NRC regulations for the protection of public health and safety, as well as the environment, with substantial safety features. 

Approval of the construction permit is an important step forward that could take up to 30 months. Once the permit is received and upon Dow confirming the ability to deliver the project while achieving its financial return targets, construction could begin. Dow expects the cost of energy ‐ net of all subsidies ‐ to be competitive with other alternatives for firm, clean energy.   

“This is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the U.S.,” said Edward Stones, business vice president, Energy & Climate, Dow. “We look forward to engaging with the NRC, DOE, our business partners and the community throughout the application process.”

“The construction permit application is a critical step to deliver on the vision of Congress and DOE to position the U.S. at the forefront of commercializing advanced reactor technology,” said J. Clay Sell, chief executive officer of X-energy. “Together with our world-class partner, Dow, we will demonstrate how the technology deployed at Seadrift, Texas, can be quickly and efficiently replicated to meet incredible power demand growth across America.” 

The proposed project could begin construction later this decade and start up early next decade. The nuclear power and steam assets would eliminate most Scope 1 and 2 emissions at the site and ensure the site remains competitively advantaged for the life of the facility. 

X-energy was selected by the DOE in 2020 to develop, license, and build an operational Xe-100 advanced SMR and TRISO-X fuel fabrication facility. Since that award, X-energy has completed the engineering and preliminary design of the nuclear reactor, has begun development and licensing of a fuel fabrication facility in Oak Ridge, Tennessee, and has secured approximately $1.1 billion in private capital to commercialize its technology. Once complete, Long Mott Generating Station is expected to be the first grid-scale advanced nuclear reactor deployed to serve an industrial site in North America.

Dow’s Seadrift site covers 4,700 acres and manufactures more than 4 billion pounds of materials per year used across a wide variety of applications including food packaging and preservation, footwear, wire and cable insulation, solar cell membranes, and packaging for medical and pharmaceutical products.

X-energy Awarded $148.5 Million Investment Tax Credit for First-of-a-Kind TRISO-X Fuel Fabrication Facility

OAK RIDGE, Tn., April 23, 2024 – X Energy, LLC (“X-energy”) has been awarded a $148.5 million tax credit for the construction by its wholly-owned subsidiary, TRISO-X LLC (“TRISO-X”), of a first-of-a-kind advanced nuclear fuel fabrication facility (“TX-1”) in Oak Ridge, Tennessee. Funded by the Inflation Reduction Act of 2022, the award is part of the Qualifying Advanced Energy Project Tax Credit (48C) program jointly administered by the U.S. Department of Energy (“DOE”), the U.S. Department of the Treasury, and the Internal Revenue Service (“IRS”).

“This award is not just an investment in our technology and innovations, it’s a massive step forward for building the supply chain to advance the next generation of nuclear energy,” said X-energy CEO, J. Clay Sell. “Strengthening energy security here and around the world requires expanding secure, domestic manufacturing capabilities across the energy sector. We applaud Congress and the Department of Energy for creating opportunities to enable the delivery of TRISO-X fuel on a commercial scale.”

X-energy’s investment in the TX-1 project is expected to create approximately 400 permanent jobs and 475 construction jobs. The 215,000-square-foot TX-1 fuel fabrication facility is designed to produce up to 714,000 pebbles per year along with other nuclear fuel products. Located within the Horizon Center Industrial Park, the 110-acre TRISO-X campus is situated on land that was formerly part of the Oak Ridge National Laboratory (“ORNL”) and was part of a tract released in 1996 for private development to help diversify the region’s economic base. TRISO-X acquired the campus from the Oak Ridge Industrial Development Board in 2022.

TRISO-X has already requested a 40-year license from the Nuclear Regulatory Commission (“NRC”) to possess and use special nuclear material to manufacture advanced nuclear fuel. Its application was submitted and accepted by the NRC in 2022.The Commission currently reports that the review is 45% complete.

Tri-structural isotropic (“TRISO”) particle fuel is considered “the most robust nuclear fuel on the planet,” according to the DOE, because it can withstand very high temperatures without melting, which is key to its safety. TRISO-X manufactures its own proprietary version of TRISO fuel to ensure supply, improve quality, and reduce costs. TRISO-X has operated a pilot nuclear fuel fabrication facility at ORNL since 2016, serving as a demonstration facility of the company’s patented TRISO fabrication processes.

The U.S. Department of Energy’s Advanced Reactor Demonstration Program (“ARDP”) is supporting the initial deployment of X-energy’s Xe-100 advanced small modular reactor at Dow’s Seadrift, Texas facility. It is expected to be the first grid-scale advanced nuclear reactor deployed to serve an industrial site in North America. ARDP is also providing support for the development of TX-1, and the initial TRISO-X nuclear fuel produced in Oak Ridge will be used for the project.

UK Government Selects X-energy and Cavendish Nuclear for First Advanced Modular Reactor Award from Future Nuclear Enabling Fund

WARRINGTON, England – X-Energy UK Holdings, Ltd (“X-energy”), a wholly-owned subsidiary of X-Energy Reactor Company, LLC, and Cavendish Nuclear, a wholly-owned subsidiary of Babcock International, today welcomed a funding award from the UK Government’s Future Nuclear Enabling Fund (“FNEF”) to further the development of their plans for Advanced Modular Reactors (AMRs) in the UK.

The Government’s award of £3.34 million will be matched by X-energy for a total programme of £6.68 million. The companies will use the funds to develop UK-specific deployment plans including an assessment of domestic manufacturing and supply chain opportunities, constructability, modularisation studies, and fuel management.

X-energy and Cavendish Nuclear also announced a partnership with Kier Group (“Kier”), a leading UK provider of construction and infrastructure services, to support constructability and supply chain analyses. Kier joins steel producer and engineer Sheffield Forgemasters and the Nuclear Advanced Manufacturing Research Centre (NAMRC) to support X-energy and Cavendish Nuclear in completing the scope outlined in their FNEF proposal. The companies’ goal is for 80% of the value of the Xe-100 projects to flow to UK firms. Last year X-energy and Cavendish Nuclear signed a memorandum of understanding with Howden, the Glasgow-based gas circulator manufacturer. They will also work with Nuclear Waste Services to review the approach to spent fuel management.

“We are backing innovation in nuclear – from building large-scale plants better to encouraging new advanced technologies – to achieve our ambition for a quarter of our electricity to come from nuclear power by 2050,” Minister for Nuclear & Renewables Andrew Bowie said. “This funding supports the next step in the development of advanced modular reactors and shows our commitment to keeping the UK at the forefront of nuclear technology.”

“We are delighted to receive this FNEF award from the Government. It reflects the readiness of our advanced technology to contribute to the UK’s energy needs in the next wave of new nuclear,” said Carol Tansley, X-energy’s UK market leader and Vice President of Projects. “Building on X-energy’s initial deployment with Dow on the U.S. Gulf Coast, we can create both jobs and long-term energy security in the UK with clean, reliable advanced nuclear power.”

“As X-energy’s UK deployment partner we’re pleased to welcome this award as a key step forward. A fleet of Xe-100s can complement renewables by providing constant or flexible power and produce steam to decarbonise industry and manufacture hydrogen and synthetic transport fuels,” said Mick Gornall, Managing Director of Cavendish Nuclear. “Deployment in the UK will create thousands of high-quality, long-term jobs across the country.”

The FNEF is intended for potential nuclear projects with mature technologies that could be in a position to take a Final Investment Decision (FID) within the next parliament. It aims to help industry reduce project risks so they are better positioned for future investment decisions.

X-energy and Cavendish Nuclear are proposing to develop a multi-billion pound 12-reactor plant at Hartlepool, to be ready by the early 2030s. The companies plan to build a fleet of up to 40 of the advanced small modular Xe-100 reactors in the UK, creating thousands of high-quality jobs in construction and operations. This would provide 3,200 MW of electricity, enough power for 6 million homes, or 8,000 MW of versatile high temperature heat and steam to support zero-carbon manufacturing and industrial processes.

The companies plan to engage with the UK nuclear regulators to evaluate approaches to licensing the Xe-100 AMR. The design is already progressing through initial assessments by nuclear regulators in Canada and the United States.
