US nuclear firm to deploy multiple 390 MW reactors for 4 GW power under new deal

Terrestrial Energy and Riot Platforms signed a deal to colocate advanced nuclear reactors with future data centers.

The plan pairs Terrestrial’s fourth-generation IMSR molten-salt technology with Riot’s AI and high-performance computing infrastructure.

The agreement could supply up to 4 GW of reliable power, helping meet surging data center electricity demand.

It highlights how AI is pushing operators toward long-term nuclear baseload contracts as a low-carbon option.
