Description

  • Content Description: Highly enriched uranium-containing graphite-based material from the Los Alamos National Laboratory (LANL) is currently stored at the Idaho National Engineering and Environmental Laboratory (INEEL). Measurements to verify the uranium content of these samples are required prior to their disposition to the Y-12 facility in Tennessee. The stored materials vary significantly in their matrix purity and in their {sup 235}U content and enrichment. A set of 26 samples selected from the LANL material inventory were analyzed non-destructively using an Active Well Coincidence Counter (AWCC) calibrated versus pure UO{sub 3} standards. A correction, calculated from published data and the approximate carbon-to-uranium atom ratios of each sample, was applied for the response enhancement from the carbon matrix. In some cases this correction was as high as 30%. Eight of the 26 sample that had been analyzed in the AWCC were destructively analyzed to provide a benchmark for the non-destructive analyses. The average recovery (NDA/Destructive results) was 0.997 {+-} 0.115. One sample had a destructive result that lay outside a 3-sigma interval about the NDA result.
