dc.description.abstractThis paper is concerned with the evaluation of the effective resonance integral for a close-packed lattice of fuel elements in beryllium oxide moderator. For this evaluation the usual theory of resonance absorption is extended to allow for flux depression in the moderator. Further, the fuel elements under consideration consist of clusters of seven rods, so that it is necessary to determine the effective surface area for such a cluster. When the fuel elements are composed of U235, Th232 and Be atoms in the ratio of approximately 1:35:1200 and the BeO moderator occupies almost three and half times the volume of the fuel rods, the effective resonance integral is found to be almost about 60% of the value for a homogeneous system of the same composition.en_AU
