Characterization investigation study: Volume 2, Chemical and radiological analysis of waste pits

The Feed Materials Production Center (FMPC) was constructed to produce high purity uranium metal for use at various Department of Energy facilities. The waste products from these operations include: general uncontaminated scrap and refuse, contaminated and uncontaminated metal scrap, waste oils, low-level radioactive waste, co-contaminated wastes, mixed waste, toxic waste, sludges from water treatment, and fly ash from the steam plant. This material has been stored in designated areas and is estimated to total more than 350,000 cubic meters. Most of the process waste is contained in pit nos. 1 through 6. Specific alternatives are being developed and evaluated for the final disposition of the waste inventory currently stored at the site. Selective investigations were conducted to characterize the material contained within the approximate 100-acre Waste Storage Area. This report presents the methodology used to sample and analyze the waste materials. A total of 790 samples was obtained for the various types of analyses. A portion of each sample was immediately sealed for volatile organic analysis for later compositing in the laboratory, a portion for gamma ray spectral analysis, and a composite made of samples from each borehole for nonvolatile chemical and radiochemical analysis. Chain-of-custody forms were completed for each sample. 12 refs., 10 figs., 37 tabs
