SK Innovation sold part of its stake in TerraPower to KHNP on January 23, 2026, making KHNP the first Korean public energy company to directly invest in an SMR developer. KHNP completed CFIUS review in December 2025. The three-way KHNP-SK Innovation-TerraPower partnership targets additional SMR projects in the US and overseas and will finalise commercialisation agreements in the first half of 2026. TerraPower CEO Chris Levesque stated the company has built strong relationships with multiple Korean companies across the nuclear energy supply chain. SK Innovation contributes energy and materials expertise, KHNP brings roughly 50 years of nuclear plant construction and operating experience, and TerraPower provides the Natrium technology; the partnership targets data centres, industrial sites and grid power in Korea and overseas. This record describes a corporate investment and partnership rather than a specific plant, so its capacity_mw (345, one Natrium unit) is a placeholder.
