Tank 241-BY-107, Cores 151 and 161, Analytical Results for the 45 day report

This document is the 45-day laboratory report for tank 241-BY-107. Push mode core segments were removed from risers 8 and 9B between June 5, 1996, and July 26, 1996. Segments were received and extruded at the 222-S Analytical Laboratory. Analyses were performed in accordance with Tank 241-BY-107 Push Mode Core Sampling and analysis Plan (TSAP) and the Safety Screening Data Quality Objective (DQO). None of the subsamples submitted for Total Alpha Activity (AT) analysis or Differential Scanning Calorimetry (DSC) exceeded the notification limits as stated in the DQO. Statistical evaluation of results by calculating the 95% upper confidence limit is not performed by the 222-S Laboratory and is not considered in this report. Primary safety screening results are included in the data summary table. The raw data from DSC and TGA analyses are included in this report
