A TWO-DIMENSIONAL ANALYSIS OF A SUBCRITICAL EXTERNALLY MODERATED CYLINDRICAL CAVITY REACTOR,
Abstract
Age-diffusion theory is used to perform a two dimensional analysis of a subcritical, externally moderated, cylindrical cavity reactor. In this analysis, the external moderator is limited to the sides only. No end moderation is considered. The Fermi-age equation is solved for the moder ator. Thermal diffusion equations for the core and moderator are also formulated and solved. An extraneous, line neutron source of strength S sub x cos pi z/h is assumed on the axis of the cylindrical cavity. Application of the diffu sion theory boundary conditions gives an expres sion relating the core flux power constant with the fuel loading, reactor size, and the maximum source strength, S sub x, sample calculations are made for an assumed reactor size, and source strength, S sub x, graphite moderator, and varying pressure and enrichments of UF6 fuel.
