The proposed technology will be crucial for the successful implementation of thermal spectrum NTP systems, specifically LEU fueled NTP systems. They can also be applied to other space nuclear systems for power production. The technology proposed here would enable not only the extension of core lifetimes without having control systems with a large reactivity worth, but will also be able to suppress fluctuations in reactivity. This will allow the use of automated systems to manage and operate nuclear power systems in support of NASA missions to other planetary bodies, asteroids, or space stations where there is a need for large amounts of power and an absence of sunlight or other energy sources to supply it.While these systems are being designed for NTPs, the knowledge gained and systems developed can also be applied to terrestrial systems. Specifically, this technology can be applied to terrestrial nuclear systems that need to be small and compact and have to operate in remote locations for extended periods of time where increased reliability throughout the reactor's lifetime is necessary.
