Tank 30 and 37 Supernatant Sample Cross-check and Evaporator Feed Qualification Analysis -2012.

摘要

This report summarizes the analytical data reported by the F/H and Savannah River National Laboratories for the 2012 cross-check analysis for high level waste supernatant liquid samples from SRS Tanks 30 and 37. The intent of this Tank 30 and 37 sample analyses was to perform cross-checks against routine F/H Laboratory analyses (corrosion and evaporator feed qualification programs) using samples collected at the same time from both tanks as well as split samples from the tanks. Of the eight Tank 30 and 37 samples pulled, two were pulled at the surface of each tank and two others were variable depth samples (Tank 30 pulled from 218 inches and Tank 37 pulled from 340 inches) from each tank. Four of these samples were delivered to SRNL and the other four samples were delivered to F/H Laboratory for characterization and eventual compilation of the data to compare and identify inconsistencies in the analytical results for routine high level waste tank supernate characterization by the two laboratories. These Tanks 30 and 37 samples sent to each laboratory constitute two sets of data; one set from each laboratory. A third set of data, derived from splitting the SRNL sample set into nearly two nearly equal parts, was sent to F/H Laboratory. In all, three sets of Tanks 30 and 37 supernatant liquid samples were analyzed by both laboratories (One half split-sample set from SRNL and two sets from F/H Laboratory) for this cross-check evaluation.
