Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy (DOE) Office of River Protection (ORP) has requested that the Savannah River National Laboratory (SRNL) provide expert evaluation and experimental work in support of the River Protection Project vitrification technology development. DOE is building the Hanford Tank Waste Treatment and Immobilization Plant (WTP) at the Hanford Site in Washington to remediate 55 million gallons of radioactive waste that is temporarily stored in 177 underground tanks. The low-activity waste (LAW) fraction will be partitioned from the high-level waste (HLW). Both the LAW and HLW will then be vitrified into borosilicate glass using Joule-heated ceramic melters. Efforts are being made to increase the loading of Hanford tank wastes in the glass while conforming to processing requirements and product quality regulations. DOE-ORP has requested that SRNL support the advancement of glass formulations and process control strategies in key technical areas, as defined in the Task Technical and Quality Assurance Plan (TTQAP).1 One of these areas is enhancing waste glass composition/property models and broadening the compositional regions over which those models are applicable. In this report, SRNL provides chemical analysis results for several samples of a simulated LAW glass, designated LAWA44, provided by Pacific Northwest National Laboratory (PNNL) as part of an ongoing development task. 2 The objective of the PNNL task is to determine the durability of this glass using EPA Method 1313, which will include test participants at Vanderbilt University and the University of Sheffield. A report on the compositions of similar glasses (referred to as the EPA-series glasses) was issued in March 2016.3.

Download or read book Natural Zeolites written by David L. Bish and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 45 of Reviews in Mineralogy and Geochemistry is a new and expanded update of Volume 4 from 1977. Most of the material in this volume is entirely new, and Natural Zeolites: Occurrence, Properties, Applications presents a fresh and expanded look at many of the subjects contained in Volume 4. There has been an explosion in our knowledge of the crystal chemistry and structures of natural zeolites (Chapters 1 and 2), due in part to the now-common Rietveld method that allows treatment of powder diffraction data. Studies on the geochemistry of natural zeolites have also greatly increased, partly as a result of the interests related to the disposal of radioactive wastes, and Chapters 3, 4, 5, 13, and 14 detail the latest results in this important area. Until the latter part of the 20th century, zeolites were often looked upon as a geological curiosity, but they are now known to be widespread throughout the world in sedimentary and igneous deposits and in soils (Chapters 6-12). The application of natural zeolites has greatly expanded since the first zeolite volume. Chapter 15 details the use of natural zeolites for removal of ammonium ions, heavy metals, radioactive cations, and organic molecules from natural waters, wastewaters, and soils. Similarly, Chapter 16 describes the use of natural zeolites as building blocks and cements in the building industry, Chapter 17 outlines their use in solar energy storage, heating, and cooling applications, and Chapter 18 describes their use in a variety of agricultural applications, including as soil conditioners, slow-release fertilizers, soil-less substrates, carriers for insecticides and pesticides, and remediation agents in contaminated soils.

Book excerpt: In the past 10 years, there have been many developments in the field of infrared transmitting fiber optics. This is highlighted by the many different fiber compositions that have been studied around the world for numerous practical applications. This book reviews different fiber systems, describing material properties, techniques used to prepare the fibers and fiber properties with particular emphasis on optical properties. These fibers possess unique optical, mechanical, and physical properties, enabling many technologies. Examples of applications are described within given chapters, allowing an engineer or scientist to choose the most appropriate fiber for a desired application. The introduction gives the reader an overview of transmission theory so that the basic concepts are clearly understood by someone new to the field. The next several chapters describe the different types of infrared transmitting fibers, including glass fibers such as those based on silica, fluoride, and chalcogenide glasses; the crystalline fibers based on single or polycrystalline materials; and hollow waveguides. The commercial chemical sensing applications of some of these new fibers are described. The final chapter summarizes the properties of the fibers and highlights future prospects.

Download or read book The Science of Composting written by Eliot Epstein and published by CRC Press. This book was released on 1996-12-17 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE The main objective of composting is to transform organic materials into a stable usable product. Often organic materials which may have limited beneficial use in their raw state or have regulatory disposal constraints can be transformed by composting into marketable products. The limits on beneficial reuse may be regulations or they may be due to the potential for materials to be putrescible or pathogenic. Composting can be a solution for each of these. The implementation of composting on a large scale (in contrast to home or backyard composting) involves materials handling. Technological implementation of composting must be consistent with the biological demand of the system. If the biological system is violated, conditions will not be optimized for composting, and problems such as odor generation, insufficient aeration or moisture, or a combination of these conditions may result. Past problems and closure of facilities have been largely due to violations of the biological systems. Product quality with respect to particle size, inclusions, moisture content and other physical aspects are a function of engineering design. A well designed system must have the biological and engineering principles in harmony at all times.
