X-energy’s reactor technology “begins with the fuel”
The company is on the doorstep of going public and has big plans for nuclear along the Texas GulfCoast – and beyond.

At the University of Texas at Austin campus in mid-August, X-energy CEO Clay Sell, Dow Chemical CEO Jim Fitterling and Texas Governor Greg Abbott touted the promise of nuclear energy to a crowd of about 70 people.
That fireside chat was several months after Dow agreed to become the first industrial manufacturer in North America to announce the deployment of advanced nuclear technology. The chemical giant plans to site X-energy’s small modular reactor (SMR) plant at its UCC1 Seadrift Operations manufacturing site, which is located on the Gulf of Mexico coast in the Lonestar State.
Ben Reinke, who is X-energy’s Vice President of Global Business Development, spoke to Power Engineering about the Xe-100 design, a leading example of what is expected to be nuclear’s next chapter.
“Our technology really begins with the fuel,” Reinke said.
Key safety features
As Reinke explained, central to the Xe-100 reactor are fuel pebbles, which are made of graphite and each about the size of a cue ball. Inside each pebble are more than 18,000 small uranium particles.
Those particles are enriched to 15.5% and then wrapped in three layers of high-temperature tolerant ceramics. The inside and outside layers are made of pyrolytic carbon, while the middle later is silicon carbide.
Reinke said it’s these three layers that help retain radioactive fission products when the reaction occurs, even in a worst-case accident scenario. X-energy believes as a result, the Xe-100 is “meltdown-proof.”
“We designed a reactor that stacks roughly 220,000 of these pebbles inside of a graphite core, and then we flow helium through that reactor,” said Reinke, “And that together allows for this incredible safety case.”
The whole concept of wrapping uranium in these high-temperature ceramics is the basis of Tristructural Isotropic, or TRISO fuel. Reinke said a similar concept was developed decades ago, but X-energy has been taking this a step further, working to develop and commercialize its pebble-based design, a fuel called TRISO-X.
