Riot Platforms Inc, a developer of data centers and bitcoin mining applications, and Terrestrial Energy Inc, a small modular nuclear power plant developer, have signed a Memorandum of Understanding (MoU) to collaborate and explore co-locating advanced nuclear power plants with large-scale data centers, including bitcoin mining infrastructure deploying 390 MW and representing 4 GW increase of nuclear power.
These companies will jointly assess potential sites in the United States, including existing Riot facilities in Texas and Kentucky, as well as additional locations. The work will focus on pairing Terrestrial Energy’s planned small modular reactors with data center operations developed and run by Riot.
According to a press release, the companies will look at adapting Integral Molten Salt Reactor (IMSR) plant designs for integration with data centers under the agreement. Riot will contribute data center design and operations expertise, while Terrestrial Energy will focus on nuclear plant development and licensing. Riot said its team has experience across design, engineering, construction, operations, and leasing for hyperscale data center projects.
“Partnering with Terrestrial Energy positions our facilities at the forefront of data center deployment, utilizing clean energy and benefitting both our customers and the communities we operate in. The consistent baseload of power required by data centers presents an ideal pairing for development alongside Terrestrial’s IMSR Plants,” said Jason Les, CEO, Riot Platforms.
“This partnership brings together two companies with sector leading capabilities to unlock the tremendous value in IMSR Plant supply to data center operations and to build long-term strategic depth in Riot Platforms’ power-first strategy,” says Simon Irish, CEO, Terrestrial Energy. “Riot has proven it can build and operate large-scale digital infrastructure, and our small and modular IMSR Plant is designed to deliver the reliable, low-cost power those operations need. Together, we see a clear path to deploying IMSR’s clean energy at scale for AI and HPC.”
The companies also plan to evaluate different configurations for matching IMSR plant output with data center demand, using Riot’s internal design framework for hyperscale facilities. Terrestrial Energy’s IMSR design separates energy conversion systems from regulated nuclear components by housing them in a separate thermal and electric facility. The company said this allows for flexible configurations, including potential hybrid setups using natural gas or other fuels during buildout or for operational resilience.
Terrestrial Energy plans to advance its IMSR plant projects at multiple U.S. sites. The company emphasized that its design uses standard-assay low enriched uranium (SALEU), enriched to under 5 percent U-235, rather than higher-assay fuel such as HALEU used in some other advanced reactor designs. Both companies framed the collaboration around matching steady power demand from data centers with continuous nuclear baseload generation, while also exploring hybrid and phased deployment approaches.
