United Kingdom Atomic Energy Authority

The United Kingdom Atomic Energy Authority is a UK government research organisation responsible for the development of fusion energy. It is an executive non-departmental public body of the Department for Energy Security and Net Zero (DESNZ). The authority focuses on United Kingdom and European fusion energy research programmes at Culham in Oxfordshire, including the world's most powerful operating fusion device, the Joint European Torus (JET). The research aims to develop fusion power as a commercially viable, environmentally responsible energy source for the future. A record 59 megajoules of sustained fusion energy was demonstrated by scientists and engineers working on JET in December 2021. United Kingdom Atomic Energy Authority owns the Culham Science Centre and has a stake in the Harwell Campus, and is involved in the development of both sites as locations for science and innovation-based business.
