Overview of the Transatlantic Nuclear Cooperation
A significant surge in U.S.-UK nuclear cooperation unfolded from September 14 to 24, 2025, culminating in over $100 billion in commercial agreements. This wave of deals, formalized under the Atlantic Partnership for Advanced Nuclear Energy on September 15, aims to align U.S. energy priorities with the UK's nuclear ambitions, particularly in reducing reliance on Russian nuclear materials and expediting reactor licensing timelines from three to four years to approximately two. The agreements were highlighted during U.S. President Donald Trump's state visit to the UK, where he announced $350 billion in bilateral deals across various sectors.
Key Agreements and Projects
Several notable agreements emerged during this period:
- Centrica and X-energy: On September 15, these companies announced a Joint Development Agreement to deploy up to 12 Xe-100 Advanced Modular Reactors at the Hartlepool site, aiming for a total capacity of 960 MW. This project is set to replace the current nuclear station, scheduled for retirement in 2028, and is expected to address grid reliability and industrial decarbonization needs.
- Holtec International and EDF UK: An MOU was signed to develop Holtec’s SMR-300 small modular reactors at the former Cottam coal-fired power station, targeting operational status in the early 2030s. This project is projected to create thousands of local jobs and transform the site into a clean energy hub.
- Last Energy and DP World: On September 15, these entities signed an MOU to develop a port-centric micro-nuclear power plant at London Gateway, backed by £80 million in private investment. The proposed PWR-20 microreactor aims to support the expansion of the Thames Freeport facility.
- TerraPower and KBR: These companies agreed to collaborate on deploying TerraPower’s Natrium reactor in the UK, which is expected to create significant job opportunities and enhance domestic supply chain capabilities.
Regulatory Harmonization and Broader Implications
The Atlantic Partnership also includes a renewed MOU between the U.S. Nuclear Regulatory Commission (NRC) and the UK's Office for Nuclear Regulation, aiming to streamline regulatory processes for advanced nuclear technologies. This collaboration seeks to cut duplication and fast-track reactor design approvals and site licensing.
The agreements are part of a broader Technology Prosperity Deal, valued at $42 billion, which encompasses advancements in AI, quantum computing, and civil nuclear energy. This deal is expected to bolster economic growth in the UK and enhance energy resilience in both nations.
Criticism and Opposition
While the agreements have been largely welcomed, some critics express concerns regarding the speed of regulatory changes and the potential implications for safety standards. There are apprehensions that hastening the licensing process may compromise thorough safety evaluations.
