Description

Los Alamos National Laboratory is offering a technology licensing opportunity for a patented Heat Pipe Reactor Fire Mitigation and Suppression System (U.S. Patent No. 12,640,276). The system transforms heat pipes in alkali metal-cooled nuclear reactors into active, sensor-driven fire defense components. It combines an inert gas buffer, a phase change material jacket, automated suppressant injection at multiple points, and optional neutron-absorber dispersion into the reactor core to deliver redundant protection that responds within milliseconds of detecting fire-like conditions. The system is designed for advanced small and microreactors, enabling developers to meet stringent safety expectations for remote, unattended, and space-constrained deployments without redesigning core architecture around bulky external suppression equipment. The technology is at TRL 3 and is available for exclusive or non-exclusive licensing.
