The Idaho National Laboratory's Transient Reactor Test Facility has received its first delivery of tri-structural isotropic (TRISO) fuel, marking a significant advancement for Project Pele, a mobile microreactor prototype created for military power needs. TRISO fuel, composed of uranium, carbon, and oxygen, is engineered to withstand extreme conditions thanks to its multi-layered coatings.

This milestone was celebrated by key stakeholders including the U.S. Army, BWX Technologies Inc., and the Department of Energy. The Strategic Capabilities Office noted that this achievement is crucial for enhancing national security and fostering innovation in advanced nuclear technologies. The delivery of TRISO fuel represents a step towards Generation IV nuclear power, supporting the Army's initiatives for reliable energy solutions.
