- Valar Atomics has successfully powered an Nvidia Blackwell chip using its Ward 250 nuclear microreactor, marking a significant milestone as the first time a next-generation nuclear reactor has generated electricity for such a purpose in the United States.
- During a live demonstration at an Emery County facility, Valar Atomics routed a small amount of electrical current from its Ward 250 reactor to an Nvidia Blackwell processor.
- Nvidia and Valar Atomics have formalized a collaborative agreement to study configurations for nuclear-supported computing installations.
- The partnership aims to design a 30-megawatt computing facility that operates independently of local municipal water supplies.
- The live demonstration showcased the microreactor powering Nvidia’s Blackwell AI chips, emphasizing advanced nuclear technology as a low-water energy option for the AI data center industry.
- This event marked the first time a microreactor has supplied electricity to a data center.
- Valar Atomics activated its Ward 250 nuclear microreactor live on stage, where it powered an Nvidia RTX Spark desktop PC.
- The reactor was turned up to 37% of its full power to activate the Blackwell-powered PC during the demonstration.
- The collaboration comes amid rising concerns over the massive electricity and water requirements of data centers, particularly for AI infrastructure.
- Nvidia has introduced a closed-loop liquid cooling system for its latest data center design, significantly reducing cooling water consumption.
- The project is part of a broader trend where technology companies are exploring dedicated power sources outside the traditional electricity grid due to environmental concerns.
- Valar Atomics is among nearly 10 startups participating in the U.S. Department of Energy’s reactor pilot program, which aims to bring advanced small nuclear reactors to criticality.
Valar Atomics has successfully powered an Nvidia Blackwell AI chip using its Ward 250 nuclear microreactor, a significant milestone in the U.S. nuclear energy landscape. This demonstration, held in Utah, showcased the reactor's ability to generate electricity for computing applications.123671012
During the event, Valar Atomics routed electrical current from the reactor to the Blackwell processor, marking the first instance of a microreactor supplying power to a data center. Isiah Taylor, CEO of Valar Atomics, stated, "Valar Atomics became the first nuclear startup to make electricity, and we did it by powering an NVIDIA Spark." The collaboration with Nvidia aims to develop a 30-megawatt closed-loop AI data center that operates independently of local water supplies, addressing growing concerns over the environmental impact of traditional data centers.
The project is part of a broader initiative to explore advanced nuclear technology as a sustainable power source for AI infrastructure. Nvidia's recent innovations, including a closed-loop liquid cooling system, aim to minimize water consumption, reducing it from millions of gallons per megawatt annually to nearly zero. This partnership reflects a shift towards dedicated power sources, as public scrutiny over data center water usage intensifies.11
Valar Atomics' reactor, designed for simplified deployment, is part of the U.S. Department of Energy's reactor pilot program, which seeks to bring advanced small nuclear reactors to criticality. The Ward 250 reactor reached initial criticality last month, producing 100 kilowatts of thermal energy during the demonstration, with plans for further development in the nuclear-supported computing sector.
“Valar Atomics has successfully powered an Nvidia Blackwell chip using its Ward 250 nuclear microreactor, marking a first in the U.S. for nuclear-generated electricity in AI applications. The collaboration aims to establish a 30-megawatt computing facility that operates independently of local water supplies.”
