The neutron distribution in the moderator of an infinite square-lattice array is found assuming diffusion theory and a uniform production of neutrons throughout the moderator. Variation of neutron flux density along the sides of a lattice cell is shown to be significant. Nevertheless, the thermal utilization of the lattice can be quite accurately calculated by the use of a “cylindricalized” cell.
