Automating Fuel Pebble Inspections
In a major step forward for advanced nuclear fuel manufacturing, Kairos Power has opened a new facility at its Manufacturing Development Campus in Albuquerque, New Mexico. This state-of-the-art facility is designed to automate fuel pebble inspections, a critical process for ensuring the quality and safety of TRISO (Tristructural Isotropic) fuel used in high-temperature gas-cooled reactors. The new installation verifies manufacturing specifications and engraves each individual fuel pebble with a unique code, allowing for precise tracing throughout testing and operational lifecycles.
X-Energy's TRISO-X Facility Progress
Simultaneously, X-Energy has achieved a major construction milestone for its own fuel fabrication ambitions. The company has successfully completed the construction of the 214,000-square-foot building that will house the TX-1 advanced nuclear fuel facility in Oak Ridge, Tennessee. This facility is dedicated to producing TRISO-X fuel, which is essential for the operation of the Xe-100 reactor design.
The completion of these specialized facilities underscores the industry's commitment to establishing a robust domestic supply chain for advanced nuclear fuels, moving beyond traditional uranium fuel assembly manufacturing.
The fabrication of HALEU-based TRISO fuel requires highly specialized processes that differ significantly from conventional light water reactor fuel. By automating inspections and expanding physical infrastructure, companies like Kairos Power and X-Energy are de-risking the fuel supply chain. These developments are vital for transitioning advanced reactor designs from the drawing board to commercial reality, ensuring that the necessary fuel is available, traceable, and manufactured to the highest safety standards.
