Integrated modeling of nuclear thermal rocket system safety and performance

The Advanced Nuclear Thermal Rocket Engine Simulator (ANTARES) environment, which consistes of an overall architecture employing state‐of‐the‐art computer hardware and an integrated physics simulation nucleus is presented. The ANTARES architecture is described, and its benefits are outlined. In an attempt to demonstrate the fidelity and ability of the physics simulator, a coupled physics methodology for use in simulating design basis accidents is presented. A preliminary high‐resolution, heat‐transfer model for use in ANTARES is also presented.
