The Fluorinel and Storage (FAST) Dissolver built by Westinghouse Idaho Nuclear Co. uses a soluble boron compound for criticality prevention. To validate the criticality codes used by Westinghouse, Los Alamos National Laboratory (LANL) designed and performed a series of experiments intended to simulate the important neutronic characteristics of the FAST dissolver. For that purpose, a nickel-reflected solution assembly fueled with highly enriched uranyl-nitrate solution containing relatively high concentrations of boron was built and is described.
