Buckling measurements were made in the Savannah River Laboratory Exponential facilities on D/sub 2/O-moderated, 19rod clusters of natural uranium oxide rods. Four triangular lattice pitches from 7.00 to 12.12 inches and a single square pitch of 8.00 pinches were used. Measurements were made at room temperature and at selected temperatures up to 218 deg C. Buckling changes resulting from voids inside housing tubes that surrounded the clusters were also measured. Intercomparisons of the results with critical void coefficient measurements demonstrated the validity of calculations for the anisotropic diffusion effects oi the voided lattices. Foil activation measurements of the lattice parameters f, L/sup 2/, p, and epsilon were made for representative lattices. The experimental results are compared with calculations. (auth)
