This week, Goodfellow led a dedicated round table on materials for nuclear fusion at the IOM3 M3P3 conference on Tuesday, 11 November. Hosted by Thomas Greaves, Goodfellow Regional Sales Manager, the table brought together specialists from academia, manufacturing, and advanced engineering to explore the challenges faced in developing materials for future fusion environments.
Tom opened the discussion by outlining Goodfellow’s position at the intersection of innovation and practical engineering within the sector. He highlighted that fusion requires materials capable of surviving some of the most extreme operating conditions imaginable, with components needing to withstand rapid thermal gradients, radiation exposure and high mechanical stresses.
The panel shared insight into their current research, from development of new steels for fusion applications to ongoing work with refractory metals such as tungsten. Participants noted the industry faces both technical and supply chain hurdles. Even when a suitable material is identified, scaling from research quantities to industrial volumes will be challenging. One contributor observed that some future reactors may require more than 1,000 tonnes of tungsten, placing significant pressure on global availability.
The group also discussed the difficulty of replicating true fusion conditions in laboratory settings. While certain aspects like heat flux can be simulated, no single test facility can fully reproduce the combined effects of temperature, irradiation and extreme environmental loads seen inside a fusion reactor. There was agreement that current testing infrastructure needs further investment to keep pace with industry requirements.
Policy and public communication were recurring themes. Members around the table remarked that fusion is often presented in oversimplified terms and that greater depth, education and clarity could help build wider understanding of the field. It was also recognised that there is a need for stable, long-term investment in UK facilities to maintain momentum and ensure the country remains competitive against international programmes.
Goodfellow has been active in the progress of fusion research for many years. The company has supplied specialist metals and alloys to several major projects, including the landmark experiment that achieved a net energy gain in nuclear fusion for the first time. Today, Goodfellow continues to support the sector with high performance materials including tungsten, molybdenum, palladium, and precision alloys, together with advanced micromachining capabilities and certified testing through Suisse Technology Partners and the Bureau of Analysed Samples.
For those exploring the field, we have also developed an eBook that reviews the key materials for fusion research, supporting researchers, engineers and developers as they advance the next stage of innovation.
Our round table at the Institute of Materials, Minerals & Mining event concluded with agreement that although significant obstacles remain, collaboration between material suppliers, researchers, policymakers and manufacturers will be essential in moving fusion from experimental progress to commercial reality.
