Experiments in the exponential facility at the Savannah River Laboratory have provided a basis for safe storage and handling of slightly enriched tubular uranium slugs. The reactivities of light-water-moderated and reflected arrays of clustered fuel slugs enriched to 1.1 wt% ²³⁵U were measured as a function of pitch, both square and triangular. This work represents an expansion of nuclear safety data presently available by providing new data on larger and concentric tubular assemblies. These data can be used to extend experimental correlations of calculational codes.
