252Cf-source-driven frequency analysis measurements have been performed for a highly enriched uranium ({approximately}93.2) metal storage vault at the Oak Ridge Y-12 Plant to provide data for verification of a calculational method for criticality safety and to assess the effects of any loss of unbound water from the concrete. The measurements showed that a 3 X 3 X 10 array of 18.75-kg uranium annular castings is essentially infinite since the results for the 5 X 5 X 10 array are not statistically different from those of the smaller array. These measured frequency analysis parameters are presented.
