Completed TRL 4 (started at 3, targeting 4)
The combined fission-fusion fuel target is the heart of an engine concept that can open the solar system to fast and efficient human exploration. This is a unique development effort for a high-performance propulsion system concept to enable faster trip times to Mars or other destinations. The current target is a highly enriched uranium shell holding Deuterium and Tritium gas at the critical point with a layer of Li6 outside the Uranium shell. Alternative targets replace the D-T with solid D-Li6. Additionally we wish to investigate the feasibility of operating more in the fast neutron spectrum by running lower enriched Uranium with thicker layers of Lithium. This work is computational only and is necessary to set up the nuclear site license with the NRC. Another part of this CIF will be to design the containment system for these experiments. We will have to develop a chamber capable of containing the blast and a storage unit to move nuclear materials to and from the experimental rig. We will validate the containment system using conventional explosives.
The proposed work as a continuation of the innovative Pulsed Fission-Fusion (PuFF) Propulsion Concept is required to properly, safely, and legally handle very small nuclear targets needed in the future for PuFF research. The work is necessary to move to the next stage in the PuFF development process and to acquire the necessary licenses. No nuclear material is involved in this CIF.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
