TerraPower Adds Korea Hydro & Nuclear Power as Strategic Investor to Accelerate Natrium Rollout

New updates have been reported about TerraPower.

TerraPower has expanded its strategic investor base by bringing Korea Hydro & Nuclear Power (KHNP) into its capitalization structure through SK’s previously announced $250 million investment, marking KHNP’s first equity stake in an advanced nuclear company and strengthening TerraPower’s global deployment prospects for its Natrium reactor technology. KHNP, a major global nuclear plant builder and operator, will support TerraPower’s first commercial Natrium project in Wyoming and help position the company for rapid follow-on deployments in the U.S., South Korea, and additional international markets, following completion of the U.S. CFIUS review in December 2025. TerraPower CEO Chris Levesque emphasized that the KHNP investment deepens the company’s long-standing relationships across the Korean nuclear supply chain and advances a multi-year strategic collaboration with SK and KHNP focused on scaling next-generation nuclear capacity worldwide.

The three companies plan to sign definitive commercialization agreements in 2026 to formalize a framework for global Natrium projects, combining TerraPower’s reactor and gigawatt-scale storage technology with KHNP’s construction and operations track record and SK’s energy and materials capabilities. Executives from KHNP and SK indicated that the partnership aims to localize key materials and components, support the Wyoming project’s execution, and establish a platform for broader advanced nuclear market expansion, positioning TerraPower as a central technology provider in emerging clean baseload markets. For TerraPower, the deal reinforces its capital base, diversifies strategic partners across geographies, and enhances its ability to execute large-scale nuclear projects, signaling growing institutional confidence in advanced reactors as part of long-term energy transition and energy security strategies.
