Advancing Fusion Remote Maintenance: Industry Collaboration Driving Innovation

4th August 2025

As part of the Fusion Futures (FF) programme, UKAEA's  Remote Applications in Challenging Environments (RACE)  has partnered with industry leaders to develop two groundbreaking technologies for remote maintenance in fusion energy engineering.

Thanks to FF funding, industry has taken the lead in maturing UKAEA technology concepts—delivering real-world solutions that enhance operational autonomy and reduce maintenance burdens in extreme environments.

Technology Highlights:

10MGy Total Integrated Dose Actuator Set  - Developed by M5TEC, this radiation-hardened actuator system is designed to operate reliably in extreme fusion environments, where high radiation levels would typically degrade mechanical components and polymer materials. This innovation enables longer autonomous operations by reducing service intervals—a key step toward greater productivity.

1MGy Total Integrated Dose Analogue-to-Digital Multiplexer  - Created by DEMCON, this radiation-tolerant multiplexer converts analogue signals into digital form directly on the remote machine, enabling robust signal transmission in high-radiation environments. It reduces cabling to remote systems by 60% and simplifies complex robotic architectures.



These advancements not only extend fusion plant operation time but also expand the UK's fusion energy supply chain knowledge and capability.

Carl Jones, Director at M5TEC, said:
"Our team is now better positioned to support the fusion industry, thanks to the knowledge and skills acquired throughout this project. This deeper understanding of fusion-specific challenges, particularly in motor and gearbox design, will enable our engineers to serve the industry more effectively and contribute to its ongoing advancements."

Bart de Jong, Project Manager at DEMCON High-tech systems, added:
"This close collaboration between UKAEA, DEMCON and other partners has resulted in timely delivery of the design, hardware and radiation tests. By flexibility of all involved we have been able to meet the tight schedule. A first step towards a robust and versatile product has been made and we are looking forward to work together with UKAEA on the next iteration."

Mike van de Mortel, Head of Operations, Electrical Engineering Unit, RACE commented:
"This programme has delivered impactful results in a short time, demonstrating the power of collaboration between UKAEA and industry. RACE is now exploring opportunities in nuclear fission and space, where this technological progress can deliver significant benefits."
