Project Pele microreactor reaches key milestone with first TRISO fuel delivery

Los Angeles CA (SPX) Dec 26, 2025
Delivery of advanced nuclear fuel to Idaho National Laboratory's Transient Reactor Test Facility marks a major step for Project Pele, a mobile microreactor prototype intended to supply resilient power for military operations. The fuel, known as tri-structural isotropic (TRISO) particle fuel, is fabricated from uranium, carbon and oxygen and formed into a small kernel. Thousands of these po
