Available in PDF, EPUB and Kindle. Book excerpt: Radioactive waste effluents at the Savannah River Plant are treated on the basis of potential off-site effects. Those wastes that are not stored in tanks or released directly to plant streams are either discharged to seepage basins or treated further to reduce their activity before being discharged. Administrative controls require that releases not result in hamnful consequences and that they are also kept as low as practical. This document describes the controls, documents the releases of radionuclides to seepage basins, and describes other methods used to treat radioactive liquid wastes. (auth).

This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new two-step process has been developed for removing sludge and cleaning Savannah River Plant waste tanks scheduled for retirement. Step 1 is a low-pressure, hydraulic-slurrying technique that uses a minimum amount of power to recirculate liquid waste and to suspend sludges. Step 2 is a chemical technique for dissolving unsuspended residue with oxalic acid, and includes water rinses and continued hydraulic slurrying. Full-scale demonstrations of the hydraulic slurrying steps in a waste tank mockup (with kaolin clay as a stand-in for waste sludges) confirmed theoretical predictions that the effective cleaning radius was directly proportional to the momentum of the jet. Small-scale dissolving tests with actual sludges showed that over 95 percent of the sludge could be dissolved in oxalic acid solutions. 24 figures.

This book was released on 2000 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 33 years of active operation of the F- and H-Area Seepage Basins to dispose of liquid low-level radioactive waste at the Department of Energy's Savannah River Site has resulted in the contamination of the groundwater underlying these basins with a wide variety of radionuclides and stable metals. The current Resource Conservation and Recovery Act (RCRA) Part B permit requires the operation of a pump-and-treat system capable of (1) maintaining hydraulic control of a specified contaminated groundwater plume, (2) treatment of the extracted groundwater, and (3) reinjection of the treated water hydraulically upgradient of the basins. Two multimillion-dollar water treatment units (WTUs) were designed and built in 1997 and the basic design consists of (1) reverse osmosis concentration, (2) chemical addition, neutralization, precipitation, polymer addition, flocculation, and clarification of the reverse osmosis concentrate, and (3) final polishing of the clarified water by ion exchange (IX) and sorption. During startup of these units numerous process optimizations were identified and, therefore, the WTUs have been recently reengineered. A systematic approach of: (1) developing a technical baseline through laboratory studies, (2) scale-up and plant testing, (3) plant modification, and (4) system performance monitoring was the basis for reengineering the WTUs. Laboratory experiments were conducted in order to establish a technical baseline for further scale-up/plant testing and system modifications. These studies focused on the following three areas of the process: (1) contaminant removal during chemical addition, neutralization and precipitation, (2) solids separation by flocculation, coagulation, clarification, and filtration, and (3) contaminant polishing of the clarified liquid by IX/sorption. Using standard laboratory-scale jar tests, the influences of pH and Fe concentration on contaminant removal during precipitation/neutralization were evaluated. The results of this work led to plant testing and operation modification that reduced the chemical dosing by a factor of 2 to 4 for one WTU and complete elimination of chemical addition at the other WTU. The solids separation process was also reengineered through polymer-dose optimization and plant modifications to control the mixing intensity and flocculation reaction time. The results were enhanced floc quality (floc size, settling rate, sludge volume, supernatant turbidity) at a polymer dose of one-half historical levels. IX/sorption optimization was initiated by evaluating 14 different IX/sorbent materials for their ability to remove specific nuclides in a series of column experiments. Analysis of time-dependent effluent activity/concentration data was used to determine the contaminant breakthrough and identify alternative resins for plant testing. Significant plant modifications, including the replacement of the natural zeolite with a commercial water softening IX resin that is one-third the cost and has twice the operational life for 90Sr removal, were made to both WTUs. The result of this reengineering has been enhanced contaminant removal, dramatically increased system reliability, lower operational costs, reduced secondary waste volume, and decreased personnel exposure. The specifics of this reengineering process and the associated system changes are presented in this paper.

Book excerpt: During 1990, low-level radiometric studies of the Savannah River continued to distinguish between effluent contributions from Plant Vogtle and the Savannah River Site. Measurements of these radioactive effluents are of mutual interest to both institutions, as they can address disturbing trends before they become health and legal concerns. The Environmental Technology Section (ETS) has conducted radiometric studies of Plant Vogtle since late 1986, prior to its startup. The plant has two 1100 MWe pressurized water reactors developed by Westinghouse. Unit 1 started commercial operations in June 1987, and Unit 2 began in May 1989. During powered operations, ETS has routinely detected neutron-activated isotopes in controlled releases but all activities have been several orders of magnitude below the DOE guide values. In 1990, processing improvements for Vogtle effluents have yielded even lower activities in the river. The Vogtle release data and the ETS measurements have tracked well over the past four years.
