UK and US Forge Nuclear Power Alliance: A New Era of Energy Security and Economic Growth

November 25, 2025

The United Kingdom and the United States have solidified a landmark agreement aimed at bolstering energy security and accelerating the development of nuclear power. This strategic partnership is set to usher in a "golden age" of nuclear energy, promising significant private investment, job creation, and a strengthened domestic energy supply.

Key Takeaways

A new UK-US deal aims to expedite the construction of nuclear power plants by streamlining regulatory processes.
The agreement is expected to unlock billions in private investment for clean energy projects.
Several new nuclear projects, including advanced modular reactors (AMRs) and small modular reactors (SMRs), are planned across the UK.
The initiative seeks to enhance energy security and reduce reliance on volatile global energy markets.
The partnership extends to fusion energy research and development.

Boosting Nuclear Power Expansion

The "Atlantic Partnership for Advanced Nuclear Energy" is designed to make it quicker for companies to build new nuclear power stations in both countries. By simplifying licensing procedures, the time required for project approval could be reduced significantly. This move is central to the UK’s ambition to become a clean energy superpower, ensuring a stable and homegrown energy supply.

Major Investment and Job Creation

This collaboration is poised to attract substantial private investment. Several key commercial deals have been announced, including:

Plans by X-Energy and Centrica to build up to 12 advanced modular reactors in Hartlepool, potentially creating 2,500 jobs and delivering significant economic value.
Holtec, EDF, and Tritax’s intention to develop advanced data centers powered by small modular reactors in Nottinghamshire, with an estimated project value of £11 billion.
Last Energy and DP World’s plan for one of the world’s first micro modular nuclear power plants to support the expansion of the London Gateway port.
Urenco and Radiant’s deal to supply advanced HALEU fuel to the US market, with plans for a UK-based Advanced Fuels Facility.
TerraPower and KBR’s evaluation of UK sites for advanced reactor technology deployment.

Strengthening Energy Security and Reducing Costs

The initiative aims to quadruple the UK’s nuclear power capacity by 2050, contributing significantly to the nation’s electricity needs. This expansion is seen as a crucial step in reducing household energy bills in the long term and insulating the UK from global energy price volatility. Furthermore, the partnership includes a commitment to eliminate dependencies on Russian nuclear material by the end of 2028.

Advancing Fusion Energy and Innovation

Beyond traditional nuclear power, the collaboration extends to fusion energy. British and American expertise will be combined with AI technology to develop advanced simulation tools and fast-track progress towards commercial fusion power. A Global Fusion Energy Policy Summit is planned for 2026 in the United States to foster international cooperation in this field.

Government Support and Future Outlook

The UK government has signaled strong support for this nuclear renaissance, with recent decisions like the final investment for Sizewell C and the development of small modular reactor programs. This strategic push aims to cement the UK’s position as a global leader in nuclear technology, driving economic growth and ensuring a secure, clean energy future.
