Abstract : A nuclear analysis was performed on a gaseous core cavity reactor suitable for space propulsion. The reactor analyzed consisted of a spherical gaseous core reactor surrounded by a carbon Beryllium reflector. To carry out this analysis, the angular segmentation (Sn) method was applied to the conservative form of the Boltzmann Equation to obtain a set of finite difference equations. The finite difference equations were then incorporated into a computer code written by the author. The computer code was programed for the IBM 7094 coupled system using Fortran IV. The code was first applied to an idealized gas core reactor which was previously analyzed by T. F. Plunckett using sixteen group diffusion theory. The difference in critical mass was 8%. After this check on the reliability of the author's code, a parametric study on the gaseous core reactor was performed. The results of this study, which determined the critical mass as a function of core radii and design thrust, are presented. (Author)
