Meeting 2026 TMS Annual Meeting & Exhibition
Symposium Additive Manufacturing: Materials Design and Alloy Development VII – Design With Multi-Modal and Field Data by Integrating Uncertainty
Presentation Title The science, engineering, and manufacture of materials for fusion energy.
Author(s) Cody A. Dennett
On-Site Speaker (Planned) Cody A. Dennett
Abstract Scope To deliver fusion energy to the grid, the science, engineering, and manufacture of materials for the most extreme conditions present in power systems is rapidly being advanced by industry around the world, enabled by public-private partnerships. At Commonwealth Fusion Systems (CFS), we plan to deliver the world’s first fusion power plant, ARC, in Chesterfield County, VA in the early 2030’s. To prove this technology, we’ve built the net fusion energy tokamak, SPARC, as well as a sub-scale molten-salt power loop on our campus in Devens, MA. To deliver both these and other projects, CFS maintains a core competency in materials and processing for fusion power, providing solutions to some of the major bottlenecks in fusion and laying out a structured roadmap to answer the rest. This talk will highlight some of the solutions we’ve provided to date at CFS and describe the remaining challenges on the roadmap to ARC deployment.
