Profile

Saltfoss Energy, renamed from Seaborg Technologies in April 2025, develops the Compact Molten Salt Reactor for deployment on power barges built with Samsung Heavy Industries; the first-generation design was switched from HALEU to LEU fuel in 2023 and a first barge is hoped for in the first half of 2030. No licence application has been filed and the only source reviewed is tertiary (Wikipedia), so funding and licensing status are unverified. Private; no market data apply.
