↑ 4%UK and US forge 'golden age of nuclear' with landmark energy deals. The United States and the United Kingdom have announced a significant new partnership aimed at ushering in a "golden age of nuclear" energy. This collaboration involves substantial new deals and investments between companies in both nations, designed to accelerate the construction of new nuclear power plants and bolster energy security. Key takeaways. * A new UK-US government agreement aims to expedite the licensing process for nuclear projects, potentially halving the time required. * Multiple commercial deals between US and UK companies are set to drive billions in private investment for new nuclear power stations. * The partnership includes a commitment to eliminate dependencies on Russian nuclear material by the end of 2028. * Collaboration will extend to fusion energy research, leveraging AI for advanced simulation tools. Turbocharging nuclear development. The cornerstone of this initiative is a new agreement between the UK and US governments that will streamline the regulatory process for building nuclear power stations. This is expected to reduce the time it takes to obtain a license from three to four years down to approximately two years, clearing the path for a major expansion of nuclear projects in both countries. This governmental backing has facilitated several major commercial deals: * X-Energy and Centrica: Plans to construct up to 12 advanced modular reactors (AMRs) in Hartlepool, with a broader UK-wide program targeting a 6GW fleet. This project alone is estimated to create up to 2,500 jobs and generate significant economic value. * Holtec, EDF, and Tritax: Aim to develop advanced data centers powered by small modular reactors (SMRs) at the former Cottam coal-fired power station, representing an estimated £11 billion project. * Last Energy and DP World: Will establish one of the world's first micro modular nuclear power plants to supply clean energy for DP World's London Gateway port expansion, backed by £80 million in private investment. * Urenco and Radiant: A deal worth around £4 million to supply advanced HALEU fuel to the US market, with Urenco expanding its Advanced Fuels Facility in the UK and exploring a similar US facility. * TerraPower and KBR: Will conduct studies for deploying Natrium advanced reactor technology in the UK, with each reactor expected to support numerous construction and permanent jobs. A new era of Energy security and jobs. This "golden age of nuclear" is central to the UK's mission to become an energy superpower, ensuring clean, homegrown power and enhancing energy security. The initiative is projected to create thousands of high-skilled jobs and stimulate billions in private investment, particularly benefiting industrial heartlands and coastal communities. Prime Minister Keir Starmer emphasized that the partnership is about more than just power; it's about "powering our economy, our communities, and our ambition." U.S. Secretary of Energy Chris Wright highlighted the role of commercial nuclear power in meeting rising energy demand and fueling the AI revolution, stressing the importance of allied partnerships. The collaboration also extends to fusion energy, with coordinated experimental programs and the co-hosting of a Global Fusion Energy Policy Summit in the US in 2026. Furthermore, the agreement aims to eliminate reliance on Russian nuclear material by the end of 2028, strengthening supply chain resilience. Addressing past challenges. The UK's historical challenges with nuclear project delays and high costs are being addressed through streamlined regulatory processes and new funding mechanisms like Contracts for Differences and the Regulated Asset Base model. While SMRs are seen as a key part of the future, the immediate focus remains on securing baseload power from larger projects and accelerating the deployment of advanced reactor designs. Fusion Energy and supply chain. The partnership extends to fusion energy, with plans for coordinated experimental programs and the development of advanced simulation tools using AI. The UK is also investing significantly in its domestic clean energy supply chain, aiming to "build it in Britain" and reduce reliance on foreign materials, including a commitment to prevent Russian nuclear fuel imports by 2028.
Nuclear startup Last Energy secures $100M for micro reactor development. News summary. Last Energy, a nuclear startup focused on developing compact nuclear power plants, has successfully raised $100 million in a Series C funding round led by the Astera Institute. The funding will be used to develop Last Energy's steel-encased micro reactors, designed to produce 20 megawatts of electricity, enough to power approximately 15,000 homes. This innovative approach involves using an old reactor design initially developed for the NS Savannah, the world's first nuclear-powered merchant ship. The company's reactors will be permanently encased in 1,000 tons of steel, eliminating the need for servicing during their lifetime. This funding will support the construction of a 5-megawatt pilot reactor at Texas A&M, with plans for a commercial-scale unit by 2028. This investment is part of a broader trend of increased interest in nuclear startups, driven by the growing energy demands of data centers. Story coverage.
Last Energy will use the funds to build its 5 megawatt pilot reactor in Texas, which it hopes to turn on next year.
Last Energy has raised $100 million in a Series C round led by Astera Institute to commercialise its small nuclear reactor. Galaxy Interactive, Gigafund and Woori Technology also participated in the oversubscribed funding round. The investment reflects growing interest in nuclear energy as demand for power to run artificial intelligence continues to surge. The startup is developing small reactors designed to meet increasing electricity needs driven by AI infrastructure.

The Texas A&M University System and Last Energy plan to launch a micro-nuclear reactor pilot project next summer at the Texas A&M-RELLIS technology and innovation campus in Bryan. Washington, D.C.-based Last Energy will build a 5-megawatt reactor that's a scaled-down version of its 20-megawatt reactor. The micro-reactor initially will aim to demonstrate safety and stability, and test the ability to generate electricity for the grid. The U.S. Department of Energy (DOE) fast-tracked the project under its New Reactor Pilot Program. The project will mark Last Energy's first installation of a nuclear reactor in the U.S. Private funds are paying for the project, which Robert Albritton, chairman of the Texas A&M system's board of regents, said is "an example of what's possible when we try to meet the needs of the state and tap into the latest technologies." Glenn Hegar, chancellor of the Texas A&M system, said the 5-megawatt reactor is the kind of project the system had in mind when it built the 2,400-acre Texas A&M-RELLIS campus. The project is "bold, it's forward-looking, and it brings together private innovation and public research to solve today's energy challenges," Hegar said. As it gears up to build the reactor, Last Energy has secured a land lease at Texas A&M-RELLIS, obtained uranium fuel, and signed an agreement with DOE. Founder and CEO Bret Kugelmass said the project will usher in "the next atomic era." In February, John Sharp, chancellor of Texas A&M's flagship campus, said the university had offered land at Texas A&M-RELLIS to four companies to build small modular nuclear reactors. Power generated by reactors at Texas A&M-RELLIS may someday be supplied to the Electric Reliability Council of Texas (ERCOT) grid. Also in February, Last Energy announced plans to develop 30 micro-nuclear reactors at a 200-acre site about halfway between Lubbock and Fort Worth.
