Proposed storage arrays for highly enriched uranyl-nitrate solutions produced by Westinghouse Idaho Nuclear Corporation (WINCO) consist of thin rectangular slab tanks separated from adjacent tanks by neutron moderator/isolator materials to maintain a safe subcriticality margin. To validate the criticality codes used by Westinghouse in design of this proposed storage array, Los Alamos National Laboratory, under the auspices of the Office of Nuclear Materials Production of the US Department of Energy (DOE), has designed and performed a series of benchmark experiments at the Los Alamos Critical Experiments Facility (LACEF) intended to simulate the important neutronic characteristics of the array.
