UK Announces 'Sunrise' Supercomputer Project to Boost Nuclear Fusion Research

LONDON– On March 16, the UK government officially announced a £45 million (approximately $58 million USD) investment to launch the "Sunrise" supercomputer project. Focused on advancing nuclear fusion energy research, the initiative aims to support the nation's net-zero emission targets while strengthening its competitiveness in the global clean energy sector.

Funded by the Department for Energy Security and Net Zero (DESNZ) and led by the UK Atomic Energy Authority (UKAEA), the project brings together a consortium of industry leaders including AMD, Dell Technologies, WEKA, and Intel, alongside the University of Cambridge. The supercomputer is a key component of the UK's 50-point AI Opportunities Action Plan and represents a crucial step in establishing the country's first AI Growth Zone at the Culham Campus in Oxfordshire.

Technical specifications reveal that the Sunrise supercomputer will operate at 1.4 megawatts. Built on Dell PowerEdge platforms, it will feature AMD EPYC processors and AMD Instinct GPU accelerators. The system comprises 192 dual-56-core CPU nodes and 672 GPUs, delivering 6.76 exaflops of AI-accelerated modeling capability. Scheduled to become operational in June 2025, it is set to be the world's most powerful AI supercomputer dedicated exclusively to nuclear fusion research.

Its core purpose is to tackle critical challenges in fusion energy, including plasma turbulence, advanced material development, and tritium breeder blanket technology. By leveraging high-fidelity simulation and digital twin technologies, Sunrise will significantly reduce the time and cost associated with physical testing. Furthermore, the project is expected to bolster the UK's high-performance computing capabilities, drive innovation in clean energy technologies, create numerous skilled jobs in the clean energy sector, and contribute to the nation's energy independence.

Lord Vallance, Minister for Science, Innovation, Research and Nuclear, stated, "Supporting the nuclear fusion industry not only safeguards our future energy independence but also provides high-quality, clean energy-related jobs for people across the UK. It positions the nation at the forefront of global fusion research."
