Nuclear thermal propulsion (NTP) has been identified as a high NASA technology priority area by the National Research Council because nuclear thermal rockets (NTRs) are high-thrust propulsion systems with the potential for twice the specific impulse of the best liquid hydrogen (LH)/oxygen (LOX) chemical rockets. Multiple mission studies have shown that nuclear thermal rockets would enable rapid Mars crew transfer times and would require approximately half the propellant and about 60% of the launch mass that is required by chemical rocket technologies. NTP could serve as a near-term enabling technology to reduce human transit time and mission risk in space to Near-Earth Objects (NEOs) and Mars. One approach to overcome some of issues associated with working with nuclear propulsion technologies is to separate the development of core nuclear reactor subsystem elements from the development of the critical (and more numerous and diverse) downstream thermal management and control system elements. This project looked of the feasibility of this option. Nuclear reactors, which power nuclear propulsion and power systems, and the nuclear radiation and residual radioactivity associated with these systems, impose significant constraints on technology and system development programs due to radiation safety, environmental contamination, and nuclear security concerns. There is a rigorous and time consuming process that is required for obtaining a nuclear reactor site license. Additionally, the development and testing of nuclear propulsion and power systems will have to rely on existing nuclear reactor research facilities, which only marginally meet NTP development needs. These facts, in combination with the increased security measures and standards required to safeguard nuclear material, limit the options available for developing new nuclear reactor research sites. To overcome nuclear facility infrastructure shortfalls and to mitigate the range of potential "nuclear concerns", one approach to develop required technologies to enable NTP capabilities, is to separate the development of core nuclear reactor subsystem elements from the development of the critical (and more numerous and diverse) downstream thermal management and control system elements. By separating them, the limited number of nuclear reactor research sites can concentrate on reactor system development without interference from the development of downstream elements. In this way, separate, non-nuclear test facilities can be designed and built to develop the other system elements required to convert the heat from a nuclear reactor to thrust, electricity, or other applicable components". Nuclear Propulsion and Power Non-Nuclear Test Facility (NP2NTF) represents a feasible extrapolation for extending Stennis Space Center's (SSC's) existing experience and expertise in designing and operating state-of-the-art, high flow rate, high pressure cryogenic piping systems for hydrogen and other propellants, as well as competencies in components, and instrumentation for special test equipment used in rocket propulsion testing are particularly relevant. SSC's experience in managing complex rocket propulsion test facilities and rigorous rocket propulsion test projects and engine qualification experience are key competencies that would be required for NP2NTF development and subsequent operation. SSC's extensive infrastructure that is in place, which is used for storing and utilizing large quantities of liquid hydrogen (LH) and liquid oxygen (LOX) is also a significant component required to the efficient and cost-effective operation of the NP2NTF. SSC's systems analysis and modeling capability, based on first-principles fluid physics and thermodynamics phenomena and routinely used to model, simulate, and predict the performance of SSC rocket propulsion test facilities, is also ideally suited for supporting NP2NFT design and facility characterization and performance prediction. By separating out the development testing of non-reactor core system elements, which comprise the bulk of nuclear propulsion and power systems, a NP2NTF would enable faster, less expensive, more efficient, and safer technology maturation and system development by eliminating the need to acquire and implement assets and infrastructure required for nuclear research. In this way, the development of core nuclear reactor system elements can be concentrated upon separately. SSC investigated these technologies, identified technology development options and performance requirements, and assessed feasibility.
