Star-C space nuclear power application studies

The Space Thermionic Advanced Reactor Compact, Star-C, is a space nuclear power system that can be configured to operate over a power range from a few to 50 kWe. This can be accomplished because of the modular nature of the nuclear fuel compacts, the power conversion modules and the heat-rejection components. Spacecraft integrated studies have recently been performed that include power systems level trade-offs over a range of 5 to 40 kWe, resulting in detailed dimensional and mass parameters at 5 kWe increments over this power range. A 25 kWe Star-C design and a power subsystem configuration with detailed dimensional, mass and operating parameters was developed for a candidate application. A Star-C flight qualification assessment has also been completed. This includes a detailed description of the power system and its components including isometric drawings of each of the components and subassemblies to illustrate the assembly sequence of the system. Launch, development, and operational scenarios are described. A system development and qualification plan and costs have also been prepared
