This book was released on 2019-11-15 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering Separations Unit Operations for Nuclear Processing provides insight into the fundamentals of separations in nuclear materials processing not covered in typical texts. This book integrates fuel cycle and waste processing into a single, coherent approach, demonstrating that the principles from one field can and should be applied to the other. It provides historical perspectives on nuclear materials processing, current assessment and challenges, and how past challenges were overcome. It also provides understanding of the engineering principles associated with handling nuclear materials. This book is aimed at researchers, graduate students, and professionals in the fields of chemical engineering, mechanical engineering, nuclear engineering, and materials engineering.

This book was released on 2000 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current BNFL Inc. flow sheet for pretreating Hanford High-Level tank wastes includes the use of Superlig(reg.sign)639 (SL-639) in a dual column system for removing technetium-99 (99Tc) from the aqueous fraction of the waste. This sorbent material has been developed and supplied by IBC Advanced Technologies, Inc., American Fork, UT. This report documents the results of testing the SL-639 sorbent with diluted waste [Na] (almost equal to) 5 M from Tank 241-AN-107 (an Envelope C waste, abbreviated AN-107) at Battelle Northwest Laboratories (BNW). The equilibrium behavior was assessed with batch contacts between the sorbent and the waste. Two AN-107 samples were used: (1) an archived sample from previous testing and (2) a more recent sample collected specifically for BNFL. A portion of the archive sample and all of the BNFL sample were treated to remove Sr-90 and transuranic elements (TRU). All samples had also been Cs decontaminated by ion exchange (IX), and were spiked with a technetium-95m ({sup 95m}Tc) pertechnetate tracer, {sup 95m}TcO4−. The TcO4− and total Tc K{sub d} values, assumed equal to the {sup 95m}Tc and 99Tc K{sub d}'s, respectively, are shown in Table S1. Values are averages of duplicates, which showed significant scatter. The total Tc K{sub d} for the BNFL sample is much lower than the TcO4−, indicating that a large fraction of the 99Tc is not pertechnetate.

Download or read book Microwave Assisted Sample Preparation for Trace Element Determination written by Erico Marlon Moraes Flores and published by Elsevier. This book was released on 2020-12-28 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave-Assisted Sample Preparation for Trace Element Analysis, Second Edition, describes the principles, equipment, and applications involved in sample preparation with microwaves for detecting and analyzing trace elements. Hot topics such as sample preparation for speciation, metabolomics, and halogen determination, as well as the alternatives of sample preparation for special samples (for example, carbon nanotubes, polymers, petroleum products), are also discussed. This completely updated second edition covers all the new devices and more powerful systems that have emerged in the last several years, such as Ultrawave and Ultraclave systems. New challenges in the fields of geology, environmental and biological studies -for example, the need for further determination of rare earth elements and halogens - are currently only covered in scientific journals and not in a comprehensive way. This book offers a summary of the state-of-the-art ways to meet these challenges with microwave-assisted sample preparation. The only book to cover in depth the principles, equipment, and applications of microwave-assisted sample preparation Written by experts in the field who provide a comprehensive overview of the important concepts Introduces the latest devices and systems used for in microwave-assisted techniques, including Ultrawave and Ultraclave systems
