Descriptive display of total alpha and energetics and TOC and oxlate as TOC and H{sub 2}O sample data from Hanford waste tanks

PDF Version Also Available for Download.

Description

In March 1999, staff at Lockheed Makn Hanford Company (LMHC) were asked to make a presentation to the Defense Nuclear Facilities Safety Board (DNFSB) about the safety of the waste tanks at the Hanford Site and the necessity for further tank sampling. Pacific Northwest National Laboratory provided a statistical analysis of available tank data to help determine whether additional sampling would in fact be required. The analytes examined were total alpha, energetics, total organic carbon (TOC), oxalate as TOC and moisture. These analytes serve as indicators of the stability of tank contents; if any of them fall above or below ... continued below

Description

In March 1999, staff at Lockheed Makn Hanford Company (LMHC) were asked to make a presentation to the Defense Nuclear Facilities Safety Board (DNFSB) about the safety of the waste tanks at the Hanford Site and the necessity for further tank sampling. Pacific Northwest National Laboratory provided a statistical analysis of available tank data to help determine whether additional sampling would in fact be required. The analytes examined were total alpha, energetics, total organic carbon (TOC), oxalate as TOC and moisture. These analytes serve as indicators of the stability of tank contents; if any of them fall above or below certain values, further investigation is warranted (Dukelow et al. 1995). PNNL performed an analysis of the data collected on these safety screening analytes with respect to empirical distributions and the established Safety Screening Data Quality Objectives (SS DQO) thresholds and Basis for Interim Operations (BIO) limits. Both univariate and bivariate analyses were performed. Summary statistics and graphical representations of the data were generated.
