CSNR Space propulsion optimization code: SPOC

Abstract

The Low Enriched Uranium (LEU) Nuclear Thermal Rocket (NTR) represents a significant optimization opportunity because of the numerous design parameters that can be adjusted to improve system performance. Performing these optimization studies requires an automated analysis tool that allows for thousands of NTR design iterations to be considered. A code developed by the Center for Space Nuclear Research (CSNR), known as SPOC, brings MCNP, SERPENT and a range of analysis tools together, which makes performing these trade studies substantially faster than was previously possible. In addition to performing rapid analysis, SPOC has unique capabilities which facilitate the optimization of the neutron energy spectrum in a manner that has not previously been discussed in the literature.
