UK Builds AI Supercomputer For Fusion Research

The UK government announced on Monday it will invest £45 million (about $60 million) to build Sunrise, an AI-focused supercomputer at the UK Atomic Energy Authority’s Culham campus, expected to begin operating in June. Officials say Sunrise will deliver up to 6.76 exaFLOPS of AI modeling performance, use AMD EPYC processors and Instinct GPUs, and support fusion programs including STEP and LIBRTI. The system aims to accelerate fusion simulations by enabling physics-informed AI and digital twins.
Key Points
- 1Announces £45m-funded Sunrise supercomputer delivering up to 6.76 exaFLOPS AI modeling performance
- 2Enables physics-informed AI and digital twins to accelerate fusion simulations and reduce costly experiments
- 3Provides national fusion programs and projects like STEP and LIBRTI with advanced compute to speed R&D
Scoring Rationale
High novelty and national-scale official investment; strong credibility and technical detail, but limited immediate access for most practitioners.
