Book Synopsis Hanford's Battle with Nuclear Waste Tank SY-101 by : Chuck Stewart

Download or read book Hanford's Battle with Nuclear Waste Tank SY-101 written by Chuck Stewart. This book was released on 2006. Available in PDF, EPUB and Kindle. Book excerpt: The nuclear reactors and separation plants at the Hanford Site in Washington State made the plutonium for the bombs dropped on Japan in 1945. Plutonium production expanded during the Cold War and continued into the late 1980s leaving Hanford with a majority of the national inventory of high-level radioactive waste stored in its underground tanks. This book tells the story of one specific tank, the million-gallon double-shell tank 241-SY-101 in Hanford's 200-West Area. SY-101 was a dominating element in DOE waste management for the last decade of the 20th century. The possibility of a flammable gas burn in SY-101 was acknowledged as the safety issue of highest priority in the entire DOE complex during the early 1990s. Uncontrolled crust growth demanded another large-scale emergency effort in the late 1990s that finally allowed the tank to return to service in September 2001. It received its first waste as an "active" tank in November 2002. The experience spawned a legacy of inspired engineering, tight project discipline, and supportive teamwork that still affects the Hanford culture today. This narrative presents the whole SY-101 story from the viewpoint of those who lived through it. If it makes people who work in nuclear waste management pause and worry a little when funding, scheduling, or political pressures curtail creativity and prudence, the book will have served its purpose.

Book Synopsis Hanford by : R. E. Gephart

Download or read book Hanford written by R. E. Gephart. This book was released on 2003. Available in PDF, EPUB and Kindle. Book excerpt: In Hanford: A Conversation About Nuclear Waste and Cleanup, Roy Gephart takes us on a journey through a world of facts, values, conflicts, and choices facing the most complex environmental cleanup project in the United States: the U.S. Department of Energy's Hanford Site. Starting with the top-secret Manhattan Project, Hanford was used to create tons of plutonium for nuclear weapons. Hundreds of tons of waste and millions of curies remain. In an easy-to-read, illustrated text, Gephart crafts the story of Hanford becoming the world's first nuclear weapons site to release large amounts of contaminants into the environment. This was at a time when radiation biology was in its infancy, industry practiced unbridled waste dumping, and the public trusted what it was told. Hanford history reveals how little we sometimes understand events when caught inside of them. The plutonium market stalled with the end of the Cold War. Public accountability and environmental compliance ushered in a new cleanup mission. Today, Hanford is driven by remediation choices whose outcomes remain uncertain. It's a story whose epilogue will be written by future generations. This book is an information resource, written for the general reader as well as the technically trained person. It provides an overview of Hanford and cleanup issues facing the nuclear weapons complex. Each chapter is a topical mini-series. It's an idea guide that encourages readers to be informed consumers of Hanford news, and to recognize that knowledge, high ethical standards, and social values are at the heart of coping with nuclear waste. Hanford history is a window into many environmental conflicts facing our nation; it's about building uponsuccess and learning from failure. And therein lies a key lesson: when powerful interests are involved, no generation is above pretense.

Book excerpt: Rheological characterization and small scale simulation of Hanford Tank 241-SY-101 has been initiated to aid in the remediation efforts for the Department of Energy Hanford Site. The study has been initiated in response to growing concerns about the potential flammability hazard pertaining to the periodic release of up to 10,000 cubic feet of hydrogen, nitrous oxide, nitrogen, and ammonia gases. Various stimulants emulating the radioactive waste stored in this tank have been used to ascertain the rheological parameters of the waste, simulate the ongoing processes of gas generation and release phenomenon inside the tank, and determine the feasibility of jet mixing to achieve a controlled release of the gas mixture.

Book Synopsis How We Forgot the Cold War by : Jon Wiener

Download or read book How We Forgot the Cold War written by Jon Wiener. This book was released on 2012-10-15. Available in PDF, EPUB and Kindle. Book excerpt: Hours after the USSR collapsed in 1991, Congress began making plans to establish the official memory of the Cold War. Conservatives dominated the proceedings, spending millions to portray the conflict as a triumph of good over evil and a defeat of totalitarianism equal in significance to World War II. In this provocative book, historian Jon Wiener visits Cold War monuments, museums, and memorials across the United States to find out how the era is being remembered. The author’s journey provides a history of the Cold War, one that turns many conventional notions on their heads. In an engaging travelogue that takes readers to sites such as the life-size recreation of Berlin’s "Checkpoint Charlie" at the Reagan Library, the fallout shelter display at the Smithsonian, and exhibits about "Sgt. Elvis," America’s most famous Cold War veteran, Wiener discovers that the Cold War isn’t being remembered. It’s being forgotten. Despite an immense effort, the conservatives’ monuments weren’t built, their historic sites have few visitors, and many of their museums have now shifted focus to other topics. Proponents of the notion of a heroic "Cold War victory" failed; the public didn’t buy the official story. Lively, readable, and well-informed, this book expands current discussions about memory and history, and raises intriguing questions about popular skepticism toward official ideology.

Download or read book Evaluating Detonation Possibilities in a Hanford Radioactive Waste Tank written by . This book was released on 1994. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1940s, radioactive wastes generated from the defense operations at the Hanford Site have been stored in underground waste storage tanks. During the intervening years, the waste products in some of these tanks have transformed into a potentially hazardous mixture of gases and solids as a result of radiolytic and thermal chemical reactions. One tank in particular, Tank 101-SY, has been periodically releasing high concentrations of a hydrogen/nitrous oxide/nitrogen/ ammonia gas mixture into the tank dome vapor space. There are concerns that under certain conditions a detonation of the flammable gas mixture may occur. There are two ways that a detonation can occur during a release of waste gases into the dome vapor splice: (1) direct initiation of detonation by a powerful ignition source, and (2) deflagration to detonation transition (DDT). The first case involves a strong ignition source of high energy, high power, or of large size (roughly 1 g of high explosive (4.6 kj) for a stoichiometric hydrogen-air mixture1) to directly initiate a detonation by ''shock'' initiation. This strong ignition is thought to be incredible for in-tank ignition sources. The second process involves igniting the released waste gases, which results in a subsonic flame (deflagration) propagating into the unburned combustible gas. The flame accelerates to velocities that cause compression waves to form in front of the deflagration combustion wave. Shock waves may form, and the combustion process may transition to a detonation wave.
