Book Description
This report describes the results of SuperLig{Reg} 639 column tests conducted at the Savannah River Technology Center (SRTC) in support of the Hanford River Protection Project - Waste Treatment Plant (RPP-WTP). The RPP-WTP contract was awarded to Bechtel National Inc. (BNI) for the design, construction, and initial operation of a plant for the treatment and vitrification of millions of gallons of radioactive waste currently stored in tanks at Hanford, WA. Part of the current treatment process involves the removal of technetium from tank supernate solutions using columns containing SuperLig{Reg} 639 resin. This report is part of a body of work intended to quantify and optimize the operation of the technetium removal columns with regard to various parameters (such as liquid flow rate, column aspect ratio, resin particle size, loading and elution temperature, etc.). The tests were conducted using nonradioactive simulants of the actual tank waste samples containing rhenium as a surrogate for the technetium in the actual waste. A previous report focused on the impacts of liquid flow rate and column aspect ratio upon performance. More recent studies have focused on the impacts of resin particle size, solution composition, and temperature. This report describes column loading experiments conducted varying temperature and solution composition. Each loading experiment was followed by high temperature elution of the sorbed rhenium. Results from limited testing are also described which were intended to evaluate the physical stability of SuperLig{Reg} 639 resin during exposure to repeated temperature cycles covering the range of potential processing extremes.

Book Description
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

Book Description
Radioactive wastes resulting from over 40 years of production of nuclear weapons in the U. S. are currently stored in 273 underground tanks at the U. S. Department of Energy Hanford site, Idaho National Engineering and Environmental Laboratory, Oak Ridge Reservation, and Savannah River site. Combined, tanks at these sjtes contain approximately 94,000,000 gallons of waste in a variety of forms including liquid, concrete-like salt cake, and various sludges. More than 730,000,000 curies of several radioactive isotopes are present in the underground tanks. Certainly, one of the greatest challenges facing the U. S. Department of Energy is how to characterize, retrieve, treat, and immobilize the great variety of tank wastes in a safe, timely, and cost-effective manner. For several years now, the U. S. Department of Energy has initiated and sponsored scientific and engineering studies, tests, and demonstrations to develop the myriad of technologies required to dispose of the radioactive tank wastes. In recent times, much of the Department of Energy R&D activities concerning tank wastes have been closely coordinated and organized through the Tanks Focus Area (IF A); responsibility for technical operations of the TF A has been assigned to the Pacific Northwest National Laboratory.

Book Description
We’ve all taken a dislike to someone for no real reason. But few of us nurture this hatred like the narrator of "Moon-Face". The target of his irrational malice is a man named John Claverhouse. With cold precision, the narrator sets to planning the man’s downfall. Why he has this urge, he can’t explain. But he knows he’ll feel immense satisfaction when John Claverhouse is made to suffer. In this macabre little tale, Jack London pinpoints a very common but unpleasant human trait. And then takes it to a horrifying extreme. This short story collection also includes "All Gold Canyon", which was adapted as part of the Netflix anthology movie "The Ballad of Buster Scruggs". Jack London (1876–1916) was one of the first American writers to achieve worldwide celebrity. He did so with rugged adventure stories set in forbidding landscapes. And heroes who survive by embracing their most primal instincts. His breakthrough best seller was "The Call of the Wild". Inspired by his time in the Klondike Gold Rush, this hard-hitting novel is told from the perspective of a sled dog named Buck. It’s inspired many adaptations, including a big-budget movie starring Harrison Ford. Among London’s other notable works are "White Fang", also featuring a canine protagonist, as well as "The Sea-Wolf", "Martin Eden" and "The Iron Heel".
