Advanced Nuclear Company Enters MOU with U.S. Data Center Developer

TerraPower, an advanced nuclear power company, and Sabey Data Centers (SDC), a data center developer, owner and operator, on Jan. 21 announced a memorandum of understanding to develop a strategic collaboration agreement to leverage advanced nuclear Natrium plants into SDC’s current and future data center operations.

TerraPower broke ground on America’s first advanced nuclear project in 2024, near a retiring coal facility in Wyoming.

The strategic collaboration includes exploring new Natrium plants in the Rocky Mountain region, as well as Texas, to support growing power needs for SDC-owned data centers.

“Due to the breadth of the opportunity, TerraPower and SDC will explore multiple project execution structures to meet the exponential demand in data center energy needs with TerraPower’s innovative advanced nuclear plus storage Natrium technology,” TerraPower said.

The rise of AI and data centers is projected to increase U.S. electricity demand by 323 terawatt hours by 2030.

The Natrium technology features a 345 MW sodium-cooled fast reactor with a patented molten salt-based energy storage system. The storage technology can boost the system’s output to 500 MW of power when needed and can be customized to match specific site needs.

The energy storage system is designed to keep base output steady, “ensuring constant reliability, and can quickly ramp up when demand peaks — it is the only advanced reactor design with this unique feature, and is well suited to meet the power demands of data centers,” TerraPower said.

SDC is one of the largest private data center providers in the world, with over 20 years of experience in developing, constructing and operating data centers across the nation.

The Natrium technology is the first mover in the advanced reactor sector and is well positioned to support the dramatic new energy demand for data centers, TerraPower said.

The first Natrium plant is being developed through the U.S. Department of Energy’s Advanced Reactor Demonstration Program, a public-private partnership.

That project is expected to be online in 2030 and will be the first commercial, utility-scale advanced nuclear power plant in the United States, TerraPower said.
