Invention Reference Number
This technology provides a precision tool for embedding TRISO fuel particles into nuclear fuel pellets during additive manufacturing. By enabling ordered placement rather than random distribution, the invention improves consistency and supports advanced fuel designs for high-performance reactors. This approach addresses longstanding challenges with fuel efficiency, heat transfer, and structural reliability in nuclear energy systems.
Description
Conventional TRISO pellet fabrication results in uneven particle distribution that negatively affects reactor performance. This invention introduces a specialized placement tool that allows particles to be embedded in structured patterns within a printed matrix. The system is compatible with multiple additive manufacturing processes and can be adapted for manual or automated use, including robotic integration. While details of the mechanism remain proprietary, the core concept enables repeatable, automated particle arrangements that overcome inefficiencies in traditional methods. By supporting advanced particle architectures, the technology paves the way for innovative fuel designs suitable for next-generation reactors and other high-reliability applications.
