The heat pipe reactor fire mitigation and suppression system from laboratory, transforms the heat pipes inside an alkali metal-cooled nuclear reactor from passive thermal conduits into active, sensor-driven fire defense components, giving designers of advanced small and microreactors a layered, automated safeguard against one of the most challenging hazards in their systems. By combining an inert gas buffer, a phase change material jacket, automated suppressant injection at multiple points and optional neutron-absorber dispersion into the reactor core, the system delivers redundant protection that responds within milliseconds of detecting fire-like conditions. This system enables advanced reactor developers to meet stringent safety expectations for remote, unattended and space-constrained deployments without redesigning the core architecture around bulky external suppression equipment.

Developed a system to minimize boil-off during cryogen transfer and storage using an additive manufactured injector with an augmented thermodynamic venting system (TVS). Cryogenic fluid transfer is important for both ground and space-based systems and typically requires venting of a receiver vessel during the chill and fill process to maintain a pressure favorable to fluid flow. NASA's TVS Augmented Injector offers an alternative system that gradually cools the inside of receiving tanks, improving cryogenic fluid transfer and storage efficiency and minimizing or eliminating the time the receiver tank vent needs to be open. The injector is a small piece of 3D-printed hardware that can be easily used with or integrated into tanks or filling equipment in any space or industrial application where a cryogenic fluid is being transferred. The injector may also be employed for long-term cryogenic fluid storage as a means of controlling tank pressure if integrated with a recirculation pump.
