Two steps forward for U.K. advanced nuclear
This week, two significant announcements have emerged from the United Kingdom’s advanced reactor sector.
On June 14, Rolls-Royce, the United Kingdom National Nuclear Laboratory, and the Japan Atomic Energy Agency announced that they had signed two trilateral memorandums of cooperation to collaborate on “advanced modular reactor (AMR) technology, specifically high-temperature gas-cooled reactors (HTGR), and the coated particle fuel these reactors will use.”
Separately, on June 16, Bellevue, Wash.–based TerraPower announced that its Natrium reactor design has been formally submitted for U.K. regulatory review. The company also announced the formation of a new subsidiary, TerraPower UK Ltd.
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.
