Terrestrial Energy and Riot Platforms Partner to Advance Nuclear-Powered Data Centers for AI and HPC Growth
Terrestrial Energy and Riot Platforms have announced a strategic collaboration aimed at developing a new generation of large-scale data center projects powered by advanced nuclear energy. The partnership combines Terrestrial Energy’s expertise in small modular nuclear reactor technology with Riot’s experience in hyperscale digital infrastructure and large-scale data center operations.
The two companies plan to jointly explore opportunities to develop integrated energy and computing facilities across multiple locations in the United States. Candidate sites include existing Riot operations in Texas and Kentucky, while additional potential locations are also under evaluation. The collaboration reflects a growing industry push to secure stable, long-term energy supplies for rapidly expanding artificial intelligence, cloud computing, and high-performance computing workloads.
Under the agreement, the companies will work together to customize Terrestrial Energy’s Generation IV Integral Molten Salt Reactor (IMSR) Plants for direct integration with Riot-developed and operated data centers. The goal is to create a highly efficient infrastructure model that pairs reliable, carbon-free baseload electricity generation with energy-intensive digital operations.
Demand for power from data centers has accelerated sharply in recent years due to the growth of artificial intelligence, machine learning, cloud services, and digital asset infrastructure. Hyperscale operators are increasingly seeking dependable energy sources capable of supporting round-the-clock operations while also meeting sustainability targets. The collaboration between Terrestrial Energy and Riot aims to address those challenges by combining advanced nuclear generation with large-scale computing infrastructure.
Riot Platforms has developed extensive expertise in designing, constructing, and operating large digital infrastructure projects. While widely known for its bitcoin mining operations, the company has increasingly expanded its capabilities into broader data center development. Riot’s infrastructure team brings experience across engineering, construction, leasing, operations, and large-scale facility deployment, positioning the company to pursue future hyperscale and AI-focused opportunities.
Terrestrial Energy, meanwhile, is advancing its IMSR technology as a next-generation nuclear solution designed to provide low-cost, reliable, and scalable clean energy. Unlike traditional nuclear plants, the IMSR system uses molten salt reactor technology that allows for high-temperature operation with enhanced efficiency and modular deployment capabilities.
A key feature of the IMSR Plant design is the separation between the plant’s regulated nuclear systems and its non-nuclear energy conversion systems. The non-nuclear systems are housed within what the company calls the Thermal and Electric Facility, which is physically isolated from the nuclear portion of the plant. According to Terrestrial Energy, this architecture creates operational flexibility and offers advantages in integrating nuclear power directly with industrial or commercial facilities such as data centers.
The companies believe this design could provide a significant competitive edge in the evolving small modular reactor market. By isolating energy conversion systems from nuclear systems, the IMSR Plant can support hybrid energy configurations and additional operational flexibility during project deployment.
One of the partnership’s objectives is to evaluate optimized configurations between IMSR Plant power generation and Riot’s data center operations. Riot has already completed a data center Basis of Design framework intended for large-scale hyperscale customers, and the companies will assess how IMSR Plants can best support those facilities at future development sites.
The collaboration may also involve hybrid energy systems that incorporate natural gas or other fuel sources during certain stages of project deployment. Terrestrial Energy noted that these hybrid approaches could support early-stage operations, improve resilience during construction, and address site-specific customer requirements.
Simon Irish, Chief Executive Officer of Terrestrial Energy, said the partnership combines complementary expertise from two companies operating in rapidly evolving sectors.
According to Irish, Riot has already demonstrated its ability to build and manage large-scale digital infrastructure, while Terrestrial Energy’s IMSR technology is designed specifically to provide the dependable and cost-effective energy required for those operations. He added that the companies see substantial long-term potential for deploying advanced nuclear energy to support AI and high-performance computing applications.
Irish also emphasized the broader significance of reliable power infrastructure as data center demand continues to rise globally. AI-focused facilities often require enormous amounts of electricity with minimal interruption, creating pressure on existing power grids and driving interest in dedicated energy generation assets located directly alongside computing facilities.
Jason Les, Chief Executive Officer of Riot Platforms, said dependable power availability is essential for meeting the needs of hyperscale data center customers. He noted that partnering with Terrestrial Energy positions Riot to explore advanced clean energy solutions capable of supporting future digital infrastructure growth.
Les said the steady baseload electricity provided by IMSR Plants makes advanced nuclear energy particularly well suited for co-location with data centers. He added that the partnership could diversify Riot’s future power sources while also helping create new opportunities for large-scale data center deployment.
The collaboration comes at a time when major technology companies and infrastructure developers are increasingly examining nuclear energy as a solution for long-term power security. Growing concerns around grid constraints, electricity pricing volatility, and carbon reduction commitments have accelerated interest in advanced nuclear technologies, particularly small modular reactors.
Unlike conventional large nuclear facilities, SMRs are designed to be built in smaller units with modular manufacturing approaches that may reduce construction timelines and improve scalability. Many SMR developers are targeting industrial facilities, remote operations, hydrogen production, and data centers as key future markets.
Terrestrial Energy’s IMSR technology also differentiates itself through its fuel strategy. The company plans to use standard-assay low enriched uranium (SALEU), which is enriched to less than five percent uranium-235. This is significant because several competing Generation IV reactor designs rely on high-assay low enriched uranium (HALEU), which requires enrichment levels between 15 and 20 percent uranium-235.
Industry analysts have identified HALEU availability as a major challenge for advanced reactor deployment because commercial-scale supply chains remain limited. By utilizing SALEU fuel, Terrestrial Energy believes its IMSR projects may avoid some of the supply chain risks and commercialization hurdles facing other advanced nuclear technologies.
Terrestrial Energy is currently advancing multiple IMSR project opportunities across the United States. The company says the reactor’s modular design allows deployment across a wide range of locations while also enabling delivery of both electricity and high-temperature thermal energy for industrial applications.
The ability to provide industrial process heat alongside electricity could further expand the future role of IMSR Plants beyond data centers. Potential applications include manufacturing, chemical production, hydrogen generation, and other energy-intensive industrial operations seeking low-carbon energy alternatives.
For Riot Platforms, the collaboration reflects a broader strategy focused on power infrastructure as a core competitive advantage. As energy demand from AI and hyperscale computing continues to grow, companies capable of securing scalable and reliable electricity sources may gain a significant advantage in attracting future customers and supporting long-term expansion.
The partnership between Terrestrial Energy and Riot Platforms highlights the increasing convergence between advanced energy technologies and digital infrastructure development. As computing demands rise and energy reliability becomes a strategic priority, integrated nuclear-powered data center campuses may emerge as an important model for the next generation of large-scale computing infrastructure.
