Download or read book Yields of Underground Nuclear Explosions at Azgir and Shagan River USSR and Implications for Identifying Decoupled Nuclear Testing in Salt written by and published by . This book was released on 1991 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bodywave magnitudes, mb, are recomputed using station corrections for all known Soviet underground nuclear explosions at Shagan River and Azgir. The mb values for explosions of announced yield, Y, in various parts of the world in either hard rock or below the water table were normalized to the SW part of the Shagan River testing area using previously published values of t* and mb bias. The resulting relationship, mb = 4.48 + 0.79 logY, which includes yields published by Bocharov et al. (1989) for Shagan River, differs very little from a regression that does not include those data. Using magnitudes determined from Lg at NORSAR as a standard, the Shagan River site is divided into three subareas. Yields calculated from these revised mb values and from m(Lg) are much more consistent for the same explosion; each agrees closely with the yields published by Bocharov et al. for large explosions in 1971 and 1972 in the NE and SW parts of the testing area. Yields calculated by averaging determinations from Lg and body waves for 66 explosions have a high precision at 95% confidence (mean value 1. 14) for Y> 10 kt. The explosion of 23 July 1973 of Y = 193 kt is clearly the largest underground explosion at Shagan River. The newly calculated values provide strong evidence of clustering in the distribution of yields of Soviet tests. In a special study yields of Soviet nuclear explosions, nuclear tests in salt, decoupling, evasion.

Download or read book Monitoring a Comprehensive Test Ban Treaty written by Eystein S. Husebye and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: An international treaty banning the testing of any nuclear device in any environment - a comprehensive test ban treaty (CTBT) - has been on the political agenda for nearly 40 years. Objections to a CTBT have been political, technical, or a combination of both. However, the possibilities seem better after the end of the Cold War. In the prevailing, cooperative disarmament climate a CTBT appears likely to be approved by most countries in 1996. Hence the great current interest in monitoring technologies and capabilities. Such issues are comprehensively addressed here, a preamble being devoted to the political developments and setbacks over the past 40 years. Since seismic means are considered the dominant monitoring element, they are explored in detail. Contributions cover network deployments, advanced signal processing, wave propagation in heterogeneous media, and seismic source representations, and a variety of techniques for source classification (including neural networks). Complementary monitoring techniques, such as hydroacoustics, radionuclides and infrasound, are also summarised. The IAEA operation for monitoring compliance with the Non-Proliferation Treaty is also presented. The book also includes eyewitness accounts of the Soviet 50 Mt megabomb development and test, as well as the efforts made by the state to monitor the nuclear test programmes of the western powers. Includes some 33 articles written by distinguished scientists active in CTBT monitoring research for decades.

Book excerpt: Project 1.7 of Operation TEAPOT was concerned with the measurement of surface and subsurface effects of an underground explosion of a 1.2-kt nuclear burst (Shot 7). The measurements included free-field earth and airblast effects, as well as loading on underground structural devices. This report deals with the presentation and analysis of the free-field data only; the structural data have been transmitted to the appropriate agencies for their analysis. From the 76 channels installed on TEAPOT Shot 7, 75 usable records were obtained. The free-field quantities measured include air-blast pressure, earth acceleration, earth stress and strain, and permanent earth displacement. The results are discussed by phenomenon and, in each case, the TEAPOT data are compared with pretest predictions. Also, where data are available, comparisons are made with previous underground nuclear test results. Some aspects of seismology and soil mechanics as applied to underground explosion phenomena are presented and, finally, the most pertinent high explosives results from subsequent tests conducted at the TEAPOT location are summarized.

Book excerpt: This document lists chronologically and alphabetically by name all nuclear tests and simultaneous detonations conducted by the United States from July 1945 through September 1992. Two nuclear weapons that the United States exploded over Japan ending World War II are not listed. These detonations were not "tests" in the sense that they were conducted to prove that the weapon would work as designed (as was the first test near Alamogordo, New Mexico on July 16, 1945), or to advance nuclear weapon design, or to determine weapons effects, or to verify weapon safety as were the more than one thousand tests that have taken place since June 30,1946. The nuclear weapon (nicknamed "Little Boy") dropped August 6,1945 from a United States Army Air Force B-29 bomber (the Enola Gay) and detonated over Hiroshima, Japan had an energy yield equivalent to that of 15,000 tons of TNT. The nuclear weapon (virtually identical to "Fat Man") exploded in a similar fashion August 9, 1945 over Nagaski, Japan had a yield of 21,000 tons of TNT. Both detonations were intended to end World War II as quickly as possible. Data on United States tests were obtained from, and verified by, the U.S. Department of Energy's three weapons laboratories -- Los Alamos National Laboratory, Los Alamos, New Mexico; Lawrence Livermore National Laboratory, Livermore, California; and Sandia National Laboratories, Albuquerque, New Mexico; and the Defense Threat Reduction Agency. Additionally, data were obtained from public announcements issued by the U.S. Atomic Energy Commission and its successors, the U.S. Energy Research and Development Administration, and the U.S. Department of Energy, respectively.

Download or read book James B Conant Harvard to Hiroshima and the Making of the Nuclear Age written by James Hershberg and published by Plunkett Lake Press. This book was released on 2019-07-31 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: James B. Conant (1893-1978) was one of the titans of mid-20th-century American history, attaining prominence and power in multiple fields. Usually remembered as an educational leader, he was president of Harvard University for two tumultuous decades, from the Depression to World War II to the Cold War and McCarthyism. To take that job he gave up a scientific career as one of the country’s top chemists, and he left it twenty years later to become Eisenhower’s top diplomat in postwar Germany. Hershberg’s prize-winning study, however, examines a critical aspect of Conant’s life that was long obscured by government secrecy: his pivotal role in the birth of the nuclear age. During World War II, as an advisor to Roosevelt and then Truman (on the elite “Interim Committee” that considered how to employ the bomb against Japan), Conant was intimately involved in the decisions to build and use the atomic bomb. During and after the Manhattan Project, he also led efforts to prevent a postwar nuclear arms race between the United States and the Soviet Union that, he feared, threatened the survival of civilization — an apocalyptic prospect he glimpsed in the first instant of the new age, when he witnessed the first test of the new weapon at Alamogordo on July 16, 1945. “... a vivid inquiry... a model of historiography; evocative reading...[Conant was] central to atomic policy and progress; the bomb would be as much Conant’s as it was anyone’s in Government. His inner response to that burden responsibility has long been obscured, but it is illumined here.” — Philip Morrison, The New York Times Book Review “In his splendid portrait of Conant, James Hershberg has illuminated the life of a pivotal figure in the making of U.S. nuclear, scientific, educational and foreign policy for almost a half-century. But the book is much more: It is not only an insightful narration of Conant’s life; it is also a brilliant and important account of the making of the nuclear age, a chronicle that contains much that is new... Hershberg’s superb study... is a chronicle of Conant’s moral journey and we are the wiser for his having charted Conant’s path.” — S.S. Schweber, Washington Post Book World “James G. Hershberg ably comes to grips with Conant and his hazardous times... His book is vibrantly written and compelling, and it breaches Conant’s shield of public discretion in masterly fashion, making extensive use of unpublished interviews, diaries, reports, and correspondence pried from private and governmental repositories. It is a huge, ambitious work — a history of the Cold War as Conant encountered it as well as a study of the man.” — Daniel J. Kevles, The New Yorker “... a well-written, comprehensive, nonjudgmental but sensitive biography... Conant was involved in so many and such critical events that students of almost any aspect of our public life over the past half-century will find useful the new material and helpful insights in this book... This fine biography of one of the most important and complicated of America’s twentieth-century leaders immediately establishes James Hershberg as one of America’s outstanding young historians.” — Stephen E. Ambrose,Foreign Affairs “... magnificent... Any reader interested in nuclear weapons, Cold War history or American politics from FDR to JFK will find this biography riveting.” — Priscilla McMillan, Chicago Tribune “... masterful... The prose is clear, the narrative forceful and the author’s judgments are balanced and judicious. This is simply splendid biography... The highest praise one can give for a book of this sort is that the historian has not shrunk from speaking truth to power. This book quietly but insistently does so. It should be read by the public at large as one of the definitive texts on the cold war and the nuclear age... Hershberg’s triumph is that he has prevailed over all the official lies to give us one more layer of the historical truth.” — Kai Bird, The Nation “... riveting... an impressive achievement... honest and comprehensive in its scholarship, the author has shown himself to be a historian of notable achievement and promise.” — McGeorge Bundy, Nature “Hershberg’s outstanding, balanced biography lifts the self-imposed secrecy surrounding a key architect of U.S. Cold War policy and of the nuclear age.” —Publisher’s Weekly “... [an] impressive and substantial achievement. [Hershberg] has used the life of one strategically placed individual to illuminate the most important issues surrounding America’s role and conduct in the nuclear age. His book will be invaluable to scholars assessing the impact and legacy of the group who acquired the epithet ‘wise men’ now that the Cold War has receded.” — Carol S. Gruber, Science “... definitive... a far more textured picture than one finds in Conant’s own guarded and unrevealing autobiography... an important and rewarding book... illuminating... Conant led a remarkable and eventful life in remarkable and eventful times. James Hershberg has explored that life, and those times, in exhaustive and revealing detail.” — Paul Boyer, The New Republic “James G. Hershberg has achieved the impossible. He has written a huge biography of a Harvard president that is fascinating, informative and as valuable a piece of American history as anything I have read in years... Mr. Hershberg has brought us back vividly to an age that seems remote, so long ago, but the questions about nuclear proliferation are the same, even while the answers are still ambiguous. As we watch men struggling with unanticipated post-Cold War problems and civil wars sprouting like Jason’s men at arms, it is good to read this story about a complex man who deserves an important place in our history because he helped make that history possible.” — Arnold Beichman, The Washington Times “... engrossing... A magisterial study of an awesome and intriguing public career.” —Kirkus Reviews “... entertaining... thought-provocative.” — Dick Teresi, The Wall Street Journal “Hershberg’s book helps us more clearly understand the postwar Establishment and offers a challenging appraisal of the role of elites, of universities and of the state.” — Gar Alperovitz, In These Times “Hershberg deserves great credit for cracking a tough New England walnut, analyzing this very important public figure, demonstrating how he fit into his own time and showing us what we can learn from the man.” — Daniel R. Mortensen, The Friday Review of Defense Literature “... a compelling account... an engaging examination of one of the central figures of the nuclear age. It succeeds in showing ‘one man’s intersection with great events and issues’ and in the process illuminates those issues for us all.” — American Historical Review “... well-written... Conant’s participation in one of our country’s most dynamic periods is, thanks to Hershberg, now much better understood.” — Library Journal “A reader of the book will enter the realm of the greats, the shapers of worlds created by the atomic blasts at Hiroshima and Nagasaki... Conant was no bit player in Cold War history... [the book is] very successful in weaving Conant’s subsurface persona in with his ups and downs as a prominent and committed public figure. And it leaves out little detail in describing top-level decisions involving the Cold War geopolitics of nuclear weaponry. Conant was a participant in most of these decisions—with Presidents Roosevelt and Truman themselves, their Secretaries of War and State, and, of course, all the major scientific figures of the time.” — Chemical & Engineering News “A wonderfully rich portrait that emerges from a carefully documented account of Conant’s role in the development of the atomic bomb and post-war nuclear policy... An extraordinarily well written text... Hershberg lays bare the person behind the persona — warts, dimples and all.” — Stanley Goldberg, Bulletin of the Atomic Scientists

Download or read book Stalin and the Bomb written by David Holloway and published by Yale University Press. This book was released on 2008-10-01 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classic and “utterly engrossing” study of Stalin’s pursuit of a nuclear bomb during the Cold War by the renowned political scientist and historian (Foreign Affairs). For forty years the U.S.-Russian nuclear arms race dominated world politics, yet the Soviet nuclear establishment was shrouded in secrecy. Then, shortly after the collapse of the Soviet Union, David Holloway pulled back the Iron Curtain with his “marvelous, groundbreaking study” Stalin and the Bomb (The New Yorker). How did the Soviet Union build its atomic and hydrogen bombs? What role did espionage play? How did the American atomic monopoly affect Stalin's foreign policy? What was the relationship between Soviet nuclear scientists and the country's political leaders? David Holloway answers these questions by tracing the dramatic story of Soviet nuclear policy from developments in physics in the 1920s to the testing of the hydrogen bomb and the emergence of nuclear deterrence in the mid-1950s. This magisterial history throws light on Soviet policy at the height of the Cold War, illuminates a central element of the Stalinist system, and puts into perspective the tragic legacy of this program―environmental damage, a vast network of institutes and factories, and a huge stockpile of unwanted weapons.
