Title: Ultra high temperature particle bed reactor design

Conference ·
OSTI ID:7038394

This study is a computer analysis of a conceptual nuclear reactor. The purpose of this work is to design a direct nuclear propulsion engine which could be used for a mission to Mars. The main features of this reactor design are high values for I{sub sp} and, secondly, very efficient cooling. This particle bed reactor consists of 37 cylindrical fuel elements embedded in a cylinder of beryllium which acts as a moderator and reflector. The fuel consists of a packed bed of spherical fissionable fuel particles. Gaseous H{sub 2} passes over the fuel bed, removes the heat and is exhausted out of the rocket. The design was found to be neutronically critical and to have tolerable heating rates. Therefore, this Particle Bed Reactor Design is suitable as a propulsion unit for this mission.
