A critical enabling technology in the evolutionary development of nuclear thermal propulsion (NTP) is the ability to predict the system performance under a variety of operating conditions. The ability to predict the system performance is critical for mission analysis and for control subsystem testing, as well as for the modeling of various failure modes. Performance must be accurately predicted during steady-state operation and during transient operation, such as startup, shutdown, and after-cooling. The development and application of verified and validated system models can reduce testing, cost, and time required for the technology to again reach flight-ready status. This paper discusses the progress of the interagency NASA/DOE team toward development of the Level I steady-state parametric system performance model. The component models are discussed in detail along with the base fluid systems analysis program and their integration strategy. The results of the initial verification and validation efforts are also provided.
