Dustin Greenwood will lead the development of newcleo’s U.S. operational footprint and oversee execution of the company’s American projects. Greenwood will focus on establishing operational capabilities, building strategic partnerships and supporting delivery of the company’s U.S. deployment roadmap.

Greenwood brings more than two decades of experience across nuclear operations, advanced reactor deployment, fuel cycle management and large-scale project execution. Most recently, he served as Vice President and Site Manager at BWXT Technical Services Group at Idaho National Laboratory, where he oversaw critical infrastructure project execution to support site operations. Prior to BWXT, Greenwood spent over ten years at NuScale Power, where he held a series of senior leadership positions and played a key role in advancing one of the industry’s most prominent small modular reactor programs through development and commercialization stages. His earlier experience includes leadership roles at Urenco USA and Energy Northwest, where he developed expertise spanning enrichment operations, plant performance and nuclear generation strategy.

“I'm thrilled to join newcleo at this pivotal moment in the Company's U.S. expansion,” said Dustin Greenwood. “The combination of proven lead-cooled fast reactor technology with MOX fuel fabrication represents a compelling solution to address America's clean energy needs while tackling the challenge of nuclear waste. I look forward to building the operational foundation that will bring this vision to reality.”

A former U.S. Navy nuclear professional, Greenwood began his career serving in the Navy’s nuclear propulsion program, providing the technical and operational foundation for his leadership in commercial nuclear energy. He holds an MBA from Oregon State University.

Travis Chapman Appointed Director, U.S. Regulatory Affairs and Licensing

Travis Chapman will lead newcleo’s U.S. licensing, permitting and regulatory engagement strategy, overseeing the company’s interactions with federal regulators and supporting the licensing pathway for newcleo’s advanced reactor and fuel technologies.

Chapman joins newcleo from BWXT Advanced Technologies, where he served as Director of Regulatory and Licensing, leading regulatory strategy for advanced nuclear initiatives. He brings a distinguished background spanning both government and private-sector nuclear innovation. Prior to BWXT, Chapman held senior regulatory and licensing roles at X-energy and Oklo, where he helped shape licensing approaches for advanced reactor technologies and engaged directly with the evolving U.S. regulatory framework for next-generation reactors. He also previously served at the U.S. Nuclear Regulatory Commission, providing him with firsthand knowledge of federal licensing processes and regulatory policy development.
