Abstract
An opportunity arose to measure the same three HEU metal items in both an AWCC and a shuffler that had been calibrated with the same standards in the same configurations. Radiographs showed that two of the items were irregular metal pieces and the third was an annulus. The measurement results are compared to each other and to the declared values. The measured masses are close to the declared masses for all cases except for the annulus measured with the AWCC, where the difference is 12%. Reasons for these results are discussed.
