ANALYSIS OF TANK 48H SAMPLE HTF-E-05-021

PDF Version Also Available for Download.

Description

Due to the need for additional HLW storage, successful disposition of the material in Tank 48H and return of the tank to routine service are two critically needed activities. As an initial step in the process, SRNL compositionally characterized the components of the Tank 48H slurry. Previously, a Tank 48H slurry sample was collected on August 23, 2004 (HTF-E-04-049 and HTF-E-04-050). The August 23, 2004 sample contained approximately 2 Liters of Tank 48H slurry. In December 7, 2004, Tank farm personnel added 3,019 gallons of 50 wt% caustic solution to Tank 48H. On March 6, 2005, about of 4L of ... continued below

Description

Due to the need for additional HLW storage, successful disposition of the material in Tank 48H and return of the tank to routine service are two critically needed activities. As an initial step in the process, SRNL compositionally characterized the components of the Tank 48H slurry. Previously, a Tank 48H slurry sample was collected on August 23, 2004 (HTF-E-04-049 and HTF-E-04-050). The August 23, 2004 sample contained approximately 2 Liters of Tank 48H slurry. In December 7, 2004, Tank farm personnel added 3,019 gallons of 50 wt% caustic solution to Tank 48H. On March 6, 2005, about of 4L of slurry was pulled from Tank 48H sample using a new 4.2 L sampler and sent to SRNL. Part of this sample was used for saltstone aggregation studies. The remaining Tank 48H sample was placed in a carboy for future analysis. Small portions of this sample were analyzed and the results are reported in this document. This document provides the chemical and radiological characterization of a Tank 48H slurry sample as defined in the Technical Task Request Plan and task technical and quality assurance plan. At the time of the sampling, the Tank 48H volume was 242,190 gallons (69 inches from the bottom of the tank) and the pumps were ran for 27 hours prior to sampling. The sample was collected within approximately 10 minutes of pump shutdown. A description of the sampler and method is given in Appendix A. This report compares results with those reported elsewhere (WSRC-TR-2004-00514 [HTF-E-04-049 and HTF-E-04-050] analysis), CBU-PIT-2005-00066 [Tank 48 Best Estimate Chemical Characterization as of March 17, 2005] and CBU-PIT-2005-00046 [Tank 48 Radionuclide Characterization to Support Material Disposition]. Since there was addition of 3,019 gallons of 50 wt% caustic solution to Tank 48H after issuing the WSRCTR-2004-00514 characterization report, the data from WSRC-TR-2004-00514 needs to be adjusted by dividing the results by a factor of 1.013. This adjustment is necessary to ensure meaningful comparison between data reported here and that reported in WSRC-TR-2004-00514 (or vise versa the results in this report must be increased by 1% for comparison with the WSRCTR-2004-00514 report). This adjustment factor (1.013) reflects the dilution effect resulting from the addition of 3,109 gallons of caustic solution (where the adjustment factor 1.013 = 1 + volume of caustic added/T48H volume before addition).
