The Oak Ridge National Laboratory (ORNL) is seeking commercialization partners for its Cryogenic DT Fusion Pellet Injection System. The system includes several patent-pending technologies, including a cryogenic extrusion recirculation system, a tritium-compatible cryogenic screw extruder, a tritium-compatible cryogenic pellet gas gun, and a pressure relief device for cryogenic fusion fuels. The ideal partner will have experience in fusion energy fueling systems, advanced nuclear and energy research facilities, or cryogenic engineering and containment systems. Some key features of the system include: • Cryogenic extrusion recirculation system for efficient pellet formation • Tritium-compatible materials and designs for safe handling of cryogenic tritium • Advanced seal technologies for maintaining hermetic separation • Pressure relief device for safe operation and redundant safety protection
