Covariance Matrices for Direct Dissolution of Vial Insert Samples in DWPF Mock-Up Facility
This report is prepared as part of Technical/QA Task Plan WSRC-RP-97- 351, Rev. 0 which was issued in response to Technical Task Request HLW/DWPF/TTR-970132. The issue to be addressed is the evaluation of a new method for analyzing the feed streams in the Slurry Mix Evaporator (SME) and Melter Feed Tank (MFT) at the Defense Waste Processing Facility (DWPF). The new method involves the direct dissolution (DD) of slurry samples which is intended to replace the more time-consuming current method (CM) of vitrification of slurry samples. A comparison test between the new and current methods, known as DWPF Lab Insert Test, HLWMD-DWPF-005, was performed in the DWPF Analytical Cell Mock-up Facility using PX-7 simulant. This report is concerned with the evaluation of the precision (variability) of the new method in comparison with the current method. This includes determining the number of samples analyzed by the new method that will give equivalent precision to four samples analyzed by the current (vitrification) method. The basis of comparison will be the precision of four feed stream properties: liquidus, viscosity, durability, and homogeneity. A companion report, Harris (1997b), address the issue of bias of the new method with respect to the current method.
