Overview

  • NVentures joined a $650 million funding round for TerraPower, marking Nvidia’s first direct investment in nuclear energy.
  • Funds will advance non-nuclear construction of the Natrium demonstration reactor in Wyoming, which began in June 2024.
  • The sodium-cooled fast reactor design features gigawatt-scale thermal storage capable of delivering 500 MW for five hours during peak demand.
  • TerraPower expects U.S. regulatory approval for the Natrium reactor in 2026 and aims to enter full commercial operation by 2030.
  • The investment underscores growing reliance on advanced nuclear technology to secure reliable, carbon-free power for AI and data centers.
