Unlike traditional nuclear plants, SMRs are smaller, cheaper to build, and can be constructed in modules. Their design allows for high reliability, reduced carbon emissions, and easier siting since they do not require proximity to large bodies of water.
X-energy's Seadrift reactor will use helium gas to cool billions of uranium-filled pebbles, generating temperatures near 1,000 degrees Fahrenheit to create steam for power.
"What attracted them to X-energy was that our plant configuration is four modules that produce about 320 megawatts," said Carol Lane, X-energy's vice president of government affairs. "It gives very, very high reliability, which is something that the data centers and AI centers really care about."
