This short history of nuclear regulation provides a brief over-view of the most significant events in the U.S. Nuclear Regulatory Commission's past. Space limitations prevent discussion of all the important occurrences, and even the subjects that are included cannot be covered in full detail. The first chapter of this account is taken from George T. Mazuzan and J. Samuel Walker, Controlling the Atom: The Beginnings of Nuclear Regulation, 1946-1962 (University of California Press, Berkeley, CA, 1984). The second chapter is largely based on J. Samuel Walker, Containing the Atom: Nuclear Regulation in a Changing Environment, 1963-1971 (University of California Press, Berkeley, CA, 1992). The third chapter is adopted in significant part from J. Samuel Walker, Three Mile Island: A Nuclear Crisis in Historical Perspective (University of California Press, Berkeley, CA, 2004). The findings and conclusions on events that occurred after 1979 should be regarded as preliminary and tentative; they are not based on extensive research in primary sources.

In this concise account of why America used atomic bombs against Japan in 1945, J. Samuel Walker analyzes the reasons behind President Truman's most controversial decision. Delineating what was known and not known by American leaders at the time, Walker evaluates the roles of U.S.-Soviet relations and of American domestic politics. In this new edition, Walker takes into account recent scholarship on the topic, including new information on the Japanese decision to surrender. He has also revised the book to place more emphasis on the effect of the Soviet invasion of Manchuria in convincing the emperor and his advisers to quit the war. Rising above an often polemical debate, Walker presents an accessible synthesis of previous work and an important, original contribution to our understanding of the events that ushered in the atomic age. J. Samuel Walker, historian of the U.S. Nuclear Regulatory Commission, has published six other books on the history of American foreign policy and the history of nuclear energy.

"Left behind were hundreds of burned-out buildings, whole blocks that looked as though they had been bombed into oblivion." These words, written by the Washington Post's Leonard Downie Jr., do not describe a war zone but rather the nation's capital reeling in the wake of the riots of April 1968. In the devastating aftermath of Martin Luther King's assassination, a community already exasperated by poor living conditions, unfair policing, and segregation broke into chaos. These riots brought well-documented tragedy and heartbreak - not only among the families of those who lost their lives but also among those who lost their homes, possessions, jobs, and businesses. There was anger, fear, and anxiety throughout the city of Washington, from the White House to the residential neighborhoods of the capital. There was an excruciating dilemma for President Lyndon Johnson. He was outraged by the violence in the streets, but he also keenly aware that African American citizens who joined the riots had legitimate grievances that his civil rights initiatives did little to address. J. Samuel Walker's Most of 14th Street is Gone takes an in-depth look at the causes and consequences of the Washington riots of 1968. It shows the conditions that existed in Washington's low-income neighborhoods, setting the stage for the disorders that began after King's murder. It also traces the growing fears produced by the outbreaks of serious riots in many cities during the mid-1960s. The centerpiece of the book is a detailed account of the riots that raged in Washington from the perspectives of rioters, victims, law enforcement officials, soldiers, and government leaders. The destruction was so extensive that parts of the city were described as "smoldering ruins block after block." Walker analyzes the reasons for the riots and the lessons that authorities drew from them. He also provides an overview of the struggle that the city of Washington faced in recovering from the effects of the 1968 disorders. Finally, he considers why serious riots have been so rare in Washington and other cities since 1968. Walker's timely and sensitive examination of a community, a city, and a country rocked by racial tension, violence, and frustration speaks not only to this nation's past but to its present.

How much radiation is too much? J. Samuel Walker examines the evolution, over more than a hundred years, of radiation protection standards and efforts to ensure radiation safety for nuclear workers and for the general public. The risks of radiation - caused by fallout from nuclear bomb testing, exposure from medical or manufacturing procedures, effluents from nuclear power, or radioactivity from other sources - have aroused more sustained controversy and public fear than any other comparable industrial or environmental hazard. Walker clarifies the entire radiation debate, showing that permissible dose levels are a key to the principles and practices that have prevailed in the field of radiation protection since the 1930s, and to their highly charged political and scientific history as well.

In "The Road to Yucca Mountain, " J. Samuel Walker traces the U.S. government's tangled efforts to solve the technical and political problems associated with radioactive waste. From the Manhattan Project through the designation in 1987 of Yucca Mountain in Nevada as a high-level waste repository, Walker thoroughly investigates the approaches adopted by the U.S. Atomic Energy Commission (AEC). He explains the growing criticism of the AEC's waste programs, such as the AEC's embarrassing failure in its first serious effort to build a high-level waste repository in a Kansas salt mine. Clearly and accessibly, Walker explains the issues surrounding deep geological disposal and surface storage of high-level waste and spent reactor fuel. He analyzes the equally complex and divisive question of fuel "reprocessing." He weaves reliable research with fresh insights about nuclear science, geology, politics, and public administration, making this original and authoritative account an essential guide for understanding the continuing controversy over an illusive and emotional topic.

Twenty-five years ago, Hollywood released "The China Syndrome", featuring Jane Fonda and Michael Douglas as a TVnews crew who witness what appears to be a serious accident at a nuclear power plant. In a spectacular coincidence, on March 28, 1979, less than two weeks after the movie came out, 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 account of the causes, context, and consequences of the Three Mile Island crisis. In gripping prose, J. Samuel 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. His superb account of those frightening and confusing days will clear up misconceptions held to this day about Three Mile Island. The heart of Walker's suspenseful narrative is a moment-by-moment account of the accident itself, in which he brings to life the players who dealt with the emergency: the Nuclear Regulatory Commission, the state of Pennsylvania, the White House, and a cast of scientists and reporters. He also looks at the aftermath of the accident on the surrounding area, including studies of its long-term health effects on the population, providing a fascinating window onto the politics of nuclear power and an authoritative account of a critical event in recent American history.

The NCAA men's basketball tournament is one of the iconic events in American sports. In this fast-paced, in-depth account, J. Samuel Walker and Randy Roberts identify the 1973-74 season as pivotal in the making of this now legendary postseason tournament. In an era when only one team per conference could compete, the dramatic defeat of coach John Wooden's UCLA Bruins by the North Carolina State Wolfpack ended a decade of the Bruins' dominance, fueled unprecedented national attention, and prompted the NCAA to expand the tournament field to a wider range of teams. Walker and Roberts provide a richly detailed chronicle of the games that made the season so memorable and uncover the behind-the-scenes maneuvering that set the stage for the celebrated spectacle that now fixes the nation's attention every March.

On September 11, 2001, author J. Samuel Walker was far from home when he learned of the terrorist attacks on the World Trade Center and the Pentagon. Stricken by incredulity and anxiety, he found the phone lines jammed when he tried to call his wife, who worked in downtown Washington, DC. At the time and ever since, Walker, like many of his fellow Americans, was and remains troubled by questions about the disaster that occurred on 9/11. What were the purposes of the attacks? Why did US intelligence agencies and the Defense Department, with annual budgets in the hundreds of billions of dollars, fail to protect the country from a small band of terrorists who managed to hijack four airliners and take the lives of nearly three thousand American citizens? What did responsible government agencies and officials know about Al-Qaeda and why did they not do more to head off the threat it posed? What were American policies toward terrorism, especially under Presidents Bill Clinton and George W. Bush, and why did they fall so far short of defending against a series of attacks? Finally, was the tragedy of 9/11 preventable? These are the most important questions that The Day That Shook America: A Concise History of 9/11 tries to answer. The Day That Shook America offers a long perspective and draws on recently opened records to provide an in-depth analysis of the approaches taken by the Clinton and Bush administrations toward terrorism in general and Al-Qaeda in particular. It also delivers arresting new details on the four hijackings and the collapse of the Twin Towers. J. Samuel Walker covers both the human drama and the public policy dimensions of one of the most important events in all of US history, and he does so in a way that is both comprehensive and concise.

Since the inception of the Atlantic Coast Conference, intense rivalries, legendary coaches, gifted players, and fervent fans have come to define the league's basketball history. In ACC Basketball, J. Samuel Walker traces the traditions and the dramatic changes that occurred both on and off the court during the conference's rise to a preeminent position in college basketball between 1953 and 1972. Walker vividly re-creates the action of nail-biting games and the tensions of bitter recruiting battles without losing sight of the central off-court questions the league wrestled with during these two decades. As basketball became the ACC's foremost attraction, conference administrators sought to field winning teams while improving academic programs and preserving academic integrity. The ACC also adapted gradually to changes in the postwar South, including, most prominently, the struggle for racial justice during the 1960s. ACC Basketball is a lively, entertaining account of coaches' flair (and antics), players' artistry, a major point-shaving scandal, and the gradually more evenly matched struggle for dominance in one of college basketball's strongest conferences.
