The work of the UK Atomic Energy Authority has resulted in a thriving research and development fusion cluster at the Culham Science Centre in Oxfordshire. As well as operating the world’s leading torus and spherical fusion reactors, the Culham facility benefits from being part of a consortium of 30 fusion research organisations and universities from 25 European countries and has attracted private companies from around the world, many of which plan to build demonstrator reactors at Culham.
