Three Mile Island burst into the nation's headlines twenty-five years ago, forever changing our view of nuclear power. The dramatic accident held the world's attention for an unsettling week in March 1979 as engineers struggled to understand what had happened and brought the damaged reactor to a safe condition. Much has been written since then about TMI, but it is not easy to find up-to-date information that is both reliable and accessible to the nonscientific reader. TMI 25 Years Later offers a much-needed &"one-stop&" resource for a new generation of citizens, students, and policy makers. The legacy of Three Mile Island has been far reaching. The worst nuclear accident in U.S. history marked a turning point in our policies, our perceptions, and our national identity. Those involved in the nuclear industry today study the scenario carefully and review the decontamination and recovery process. Risk management and the ability to convey risks to the general population rationally and understandably are an integral part of implementing new technologies. Political, environmental, and energy decisions have been made with TMI as a factor, and while studies reveal little environmental damage from the accident, long-term studies of health effects continue. TMI 25 Years Later presents a balanced and factual account of the accident, the cleanup effort, and the many facets of its legacy. The authors bring extensive research and writing The authors bring extensive research and writing experience to this book. After the accident and the cleanup, a significant collection of videotapes, photographs, and reports was donated to the University Libraries at Penn State University. Bonnie Osif and Thomas Conkling are engineering librarians at Penn State who maintain a database of these materials, which they have made available to the general public through an award-winning website. Anthony Baratta is a nuclear engineer who worked with the decontamination and recovery project at TMI and is an expert in nuclear accidents. The book features unique photographs of the cleanup and helpful appendixes that enable readers to investigate further various aspects of the story.
On March 28, 1979, the worst accident in the history of commercial nuclear power in the United States occurred at Three Mile Island. For five days, the citizens of central Pennsylvania and the entire world, amid growing alarm, followed the efforts of authorities to prevent the crippled plant from spewing dangerous quantities of radiation into the environment. This book is the first comprehensive, moment-by-moment account of the causes, context, and consequences of the Three Mile Island crisis. Walker captures the high human drama surrounding the accident, sets it in the context of the heated debate over nuclear power in the seventies, and analyzes the social, technical, and political issues it raised. He also looks at the aftermath of the accident on the surrounding area, including studies of its long-term health effects on the population.--From publisher description.

Normal Accidents analyzes the social side of technological risk. Charles Perrow argues that the conventional engineering approach to ensuring safety--building in more warnings and safeguards--fails because systems complexity makes failures inevitable. He asserts that typical precautions, by adding to complexity, may help create new categories of accidents. (At Chernobyl, tests of a new safety system helped produce the meltdown and subsequent fire.) By recognizing two dimensions of risk--complex versus linear interactions, and tight versus loose coupling--this book provides a powerful framework for analyzing risks and the organizations that insist we run them. The first edition fulfilled one reviewer's prediction that it "may mark the beginning of accident research." In the new afterword to this edition Perrow reviews the extensive work on the major accidents of the last fifteen years, including Bhopal, Chernobyl, and the Challenger disaster. The new postscript probes what the author considers to be the "quintessential 'Normal Accident'" of our time: the Y2K computer problem.
Written by an expert in the field, this book is perfect for those who would like to know what happened at the Fukushima Daiichi Nuclear Power Plant. Part 1 of the book studies how core melts occurred in Fukushima Daiichi units 1, 2, and 3, respectively, based on evidence from the Three-Mile Island core melt accident and fuel behavior experiments performed in the 1970s under the cooperation between the United States, Germany, and Japan. This information explains the accident processes without contradicting data from Fukushima, which was published in the TEPCO report. The hydrogen explosions in units 1, 3, and 4 are also explained logically in conjunction with the above core melt process. Part 2 clarifies how the background radiation level of the site doubled: The first rise was just a leak from small openings in units 1 and 3 associated with fire-pump connection work. The second rise led to direct radioactive material release from unit 2. Evacuation dose adequacy and its timing are discussed with reference to the accident process, and the necessity for embankments surrounding nuclear power plants to increase protection against natural disasters is also discussed. New proposals for safety design and emergency preparedness are suggested based on lessons learned from the accident as well as from new experiences. Finally, a concept for decommissioning the Fukushima site and a recovery plan are introduced.
In this book, compelling case studies show how past crises have reshaped regulation, and how policy-makers can learn from crises in the future.
This book examines the three most well-known and socially important nuclear accidents. Each of these accidents had significant, yet dramatically different, human and environmental impacts. Unique factors helped shape the overall pattern and scale of each disaster, but a major contributing factor was the different designs used for each reactor. Fukushima was a boiling water reactor (BWR), Chernobyl was a graphite moderated boiling water reactor, and TMI was a pressurized water reactor (PWR). This book traces the history of nuclear power and the development of each reactor type. We examine how GE’s work with a sodium cooled design did not fare well with the US Navy, and led GE to promulgate the BWR design. We explore the Russian atomic bomb program, its use of graphite moderated reactors, and their design modifications to create power production units. We trace the developments in the US that led the US Navy to select the PWR design, and caused the PWR to be used for nearly 2/3 of all US commercial reactors. In sum, the book uses the three major nuclear accidents as a lens to trace the technological history of nuclear energy production and to link these developments with long-term societal and environmental consequences. The book is intended for readers with an interest in nuclear power and nuclear disasters. The detailed and compelling account will appeal to both the expert and the interested lay-person.
