The United Kingdom is leveraging advanced robotics to address operational challenges in its ambitious fusion energy programs, says The Engineer. At the heart of this effort is Remote Applications in Challenging Environments (RACE), a facility developed by the U.K. Atomic Energy Authority (UKAEA). RACE uses robotic systems to manage and maintain fusion reactors—especially in environments too harsh for humans due to extreme heat, radiation, or vacuum conditions.
These robots—often built using autonomous and semi-autonomous systems—perform precision tasks such as component installation and maintenance, reflecting the same complexity and dexterity required in fusion operations.
In parallel, the United Kingdom’s flagship fusion project, the Spherical Tokamak for Energy Production (STEP), aims to deliver net electricity from fusion by approximately 2040. STEP’s design, rooted in the spherical tokamak model, is a continuation of technological advances from the United Kingdom’s MAST Upgrade and Joint European Torus (JET) facilities, both of which heavily rely on robotic maintenance and remote intervention.
Internationally, robotics also plays a crucial role. For instance, ITER—the world’s largest fusion experiment in France—features remote handling systems for maintenance and diagnostics, ensuring safety and operational efficiency under extreme reactor conditions.
Together, these global endeavors highlight how robotics is central to the engineering future of fusion energy—bridging the gap between talent, safety, and the technical complexities of high-energy environments. As fusion projects scale, robotics will be indispensable in ensuring safe, continuous, and optimized operations.
