From SPARC to ARC: CFS prepares for a first-of-a-kind fusion plant
Commonwealth Fusion Systems makes no small plans. The company wants to build a 400-MWe magnetic confinement fusion power plant called ARC near Richmond, Va., and begin operating it in the early 2030s. And the plans don’t end there. CFS wants to deploy “thousands” of fusion power plants capable of accelerating a global energy transition.
2022 International High-Level Radioactive Waste Management Conference Speaker
A nuclear and systems engineer, Ethan has 12 years of experience in deep borehole repository and advanced reactor design. He uniquely dedicated his undergraduate and PhD research to the cost and performance optimization of deep borehole repository concepts, and his contributions to the field earned him awards from the Department of Energy (DOE) in 2011 and American Nuclear Society (ANS) in 2013. After graduating, he spent 6 years as a reactor and systems engineer with successful startups (TerraPower and Oklo) licensing advanced nuclear reactors and establishing himself as an expert on sodium fast reactor design, safety, and product development. Currently, as Director of Systems Engineering at Deep Isolation, he manages the product roadmap and technical risks of the reference architecture and conducts options analysis for new waste forms and repository configurations. Ethan has authored 9 conference and journal papers related to deep borehole disposal and continues to advance the field in his role at Deep Isolation.
