MEASUREMENTS OF BUCKLINGS AND VOID EFFECTS IN D$sub 2$O MODERATED, ORGANIC OR H$sub 2$O COOLED, LATTICES OF UO$sub 2$ ROD CLUSTERS
Buckling and void effects in UO/sub 2/ rod clusters were measured. The fuel assembiies and organic and H/sub 2/O coolants were chosen to cover an extreme range of hydrogenous coolant properties. The measurements were performed in the D/sub 2/O-moderated Process Development Pile. The fuel assemblies consisted of 19, 31, or 37 UO/sub 2/ rods. The rods were made up of sintered pellets stacked in aluminum tubes. Bucklings were determined by the substitution method, in which the fuel assemblies to be measured replaced assemblies in a one- region lattice of known nuclear properties. Two analysis technlques were useda one-group perturbation method and a two-group flux matching method. Results of measurements are given in tabular form. (M.C.G.)
