The Savannah River Laboratory has performed physics studies on D/sub 2/O lattices of fuel assemblies intended for the R3/Adam reactor being built by A. B. Atomenergi. Buckling temperature coefficients up to 220 C were measured at square lattice pitches of 24.0, 27.0, and 30.0 cm centerto-center, between fuel assemblies, in the Pressurized Subcritical Experiment (PSE). Central cell foil activation traverses were also made at room temperature and at 217 C. Two building measurements at room temperature were made in the Process Development Pile (PDP) at triangular pitches of 23.7 and 30.8 cm using a substitution technique in which R3/Adam fuel replaces similar assemblies composed of smaller diameter oxide rods. The experirmental results compared well with calculations. (auth)
