Terrestrial Energy and Riot Platforms announced a collaboration to develop a best-in-class pairing of future data centers with co-located advanced nuclear plants.
As partners, Riot and Terrestrial Energy will consider project opportunities at multiple candidate sites, including existing Riot facilities in Texas and Kentucky, while jointly evaluating additional sites.
The two partners will collaborate on the customization of IMSR Plants to be integrated with Riot developed and operated data centers. This partnership combines Terrestrial Energy’s nuclear plant design and licensing expertise with Riot’s expertise in data center design, development, and operations. Riot Platforms’ veteran data center development team has extensive experience developing and delivering hyperscale data centers with collective experience spanning design, engineering, construction, operations, marketing, and leasing. Terrestrial Energy and Riot will evaluate scaling optimized configurations of IMSR Plant power supply and data center operations at candidate sites utilizing Riot’s completed data center Basis of Design optimized for large-scale hyperscale tenants.
Terrestrial Energy’s IMSR Plant is uniquely suited for data center operation. Its non-nuclear energy conversion systems, housed in the plant’s Thermal and Electric Facility, are remote and isolated from regulated nuclear systems, providing a competitive advantage in the small modular reactor sector. This design enables hybrid energy configurations, including the use of natural gas or other fuel sources to meet site-specific customer needs, support early operations, and enhance system resilience during project buildout.
Terrestrial Energy is developing IMSR Plant projects across multiple sites in the U.S. These projects leverage the IMSR Plant’s small and modular siting capabilities and the plant’s capacity to supply clean, high-temperature thermal energy for high-efficiency, low-cost electric power generation and for direct industrial process-heat use. The company’s supply chain includes use of readily available standard-assay low enriched uranium fuel enriched to less than 5% U235. This avoids the considerable supply chain challenges to commercial scale deployment from reliance on high-assay low enriched uranium fuel enriched to between 15 and 20% U235, which is used by other Generation IV reactors in the market today.
Simon Irish, CEO of Terrestrial Energy
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. 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.
Jason Les, CEO of Riot Platforms
Our data centers require reliable and predictable energy at the scale demanded by today’s hyperscale customers. 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. This partnership will bring reliable, innovative power online while diversifying Riot’s sources of power and creating new opportunities for future data center deployment.
