UK’s First AI Supercomputer to Accelerate Fusion Energy Innovation

Located at the Culham Campus in Oxfordshire, the UK’s inaugural AI supercomputer is set to become the cornerstone of the nation’s pioneering AI Growth Zone. This initiative is spearheaded by the UK Atomic Energy Authority (UKAEA) and backed by a £45 million government investment.

Sunrise: A Groundbreaking 1.4MW AI Supercomputer

Named Sunrise, this 1.4MW supercomputer is scheduled for completion by June and is highlighted in the UK’s Fusion Strategy as the world’s most powerful AI system dedicated exclusively to fusion energy research. Its deployment aims to enhance the UK’s energy resilience amid global geopolitical tensions affecting oil supply chains, such as disruptions around the Strait of Hormuz.

Strategic Importance for Energy Security and Job Creation

Patrick Vallance, the UK’s Minister for Science, Innovation, Research and Nuclear, emphasized the dual benefits of this investment: “Supporting our fusion sector not only secures future energy independence but also fosters innovation, research, and skilled clean energy employment opportunities for the British workforce.”

Advanced Computing to Address Fusion Challenges

Funded by the Department of Energy Security and Net Zero (DESNZ), Sunrise is engineered to tackle critical fusion research challenges, including plasma turbulence, material science advancements, and tritium fuel breeding. Additionally, it will bolster AI capabilities at Culham and across the UK’s high-performance computing infrastructure, aligning with the government’s AI Opportunities Action Plan and AI for Science strategy.

Collaborative Effort Featuring Industry and Academia

The 6.74 exaflops supercomputer is the result of a partnership among AMD, DESNZ, the Department for Science, Innovation and Technology (DSIT), Dell Technologies, Intel, UKAEA, the University of Cambridge, and Weka, a data platform specialist.

Cutting-Edge Hardware and AI Integration

Sunrise leverages AMD Epyc processors combined with AMD Instinct GPUs, all integrated within Dell’s PowerEdge server architecture. Thomas Zacharia, AMD’s Senior Vice President for Public Sector Strategy and Development, remarked, “Fusion research demands unparalleled computational power for extensive simulations, intricate modeling, and sophisticated AI applications to expedite scientific breakthroughs.”

Enabling Digital Twins for Fusion Systems

The UKAEA highlighted that Sunrise will facilitate high-fidelity simulations and the creation of digital twins-virtual replicas of complex fusion systems-to optimize research and development processes.

Rob Akers, Director of Computing Programmes at UKAEA, explained, “By merging physics-informed AI with detailed simulations, Sunrise will generate predictive digital twins that significantly reduce the costs, risks, and timelines associated with physical experimentation.” He added, “Our collaboration with leading partners harnesses AI and high-performance computing to advance the UK’s fusion roadmap and support the net zero agenda.”

Building on Previous AI and Supercomputing Initiatives

In 2023, Dell Technologies, Intel, the University of Cambridge, and UKAEA announced plans to utilize supercomputing and AI technologies to enhance the UK’s prototype fusion power plant designs through an ‘industrial metaverse’ approach. Further strengthening this ecosystem, a £36 million government investment was allocated in January 2026 to expand the Cambridge supercomputing center.

Future Outlook for UK Scientific Computing

Paul Calleja, Director of the Cambridge Research Computing Service, stated, “Sunrise represents a pivotal advancement in the UK’s ambition to fortify sovereign scientific computing capabilities, accelerate fusion research, and establish the foundation for the Culham AI Growth Zone.”
