The March 11, 2011, Great East Japan Earthquake and tsunami sparked a humanitarian disaster in northeastern Japan. They were responsible for more than 15,900 deaths and 2,600 missing persons as well as physical infrastructure damages exceeding $200 billion. The earthquake and tsunami also initiated a severe nuclear accident at the Fukushima Daiichi Nuclear Power Station. Three of the six reactors at the plant sustained severe core damage and released hydrogen and radioactive materials. Explosion of the released hydrogen damaged three reactor buildings and impeded onsite emergency response efforts. The accident prompted widespread evacuations of local populations, large economic losses, and the eventual shutdown of all nuclear power plants in Japan. "Lessons Learned from the Fukushima Nuclear Accident for Improving Safety and Security of U.S. Nuclear Plants" is a study of the Fukushima Daiichi accident. This report examines the causes of the crisis, the performance of safety systems at the plant, and the responses of its operators following the earthquake and tsunami. The report then considers the lessons that can be learned and their implications for U.S. safety and storage of spent nuclear fuel and high-level waste, commercial nuclear reactor safety and security regulations, and design improvements. "Lessons Learned" makes recommendations to improve plant systems, resources, and operator training to enable effective ad hoc responses to severe accidents. This report's recommendations to incorporate modern risk concepts into safety regulations and improve the nuclear safety culture will help the industry prepare for events that could challenge the design of plant structures and lead to a loss of critical safety functions. In providing a broad-scope, high-level examination of the accident, "Lessons Learned" is meant to complement earlier evaluations by industry and regulators. This in-depth review will be an essential resource for the nuclear power industry, policy makers, and anyone interested in the state of U.S. preparedness and response in the face of crisis situations.

This report provides a description of the elements which should be addressed by the team responsible for the preparation, development and implementation of a plant specific accident management programme at a nuclear power plant. The issues addressed include formation of the team, selection of accident management strategies, safety analyses required, evaluation of the performance of plant systems, development of accident management procedures and guidelines, staffing and qualification of accident management personnel, and training needs. The report is intended to facilitate the work to be done by NPP operators, utilities and their technical support organizations, but it can also be used for the preparation of relevant national regulatory requirements.

The National Academies of Sciences, Engineering, and Medicine held a workshop on August 22â€"23, 2018, in Washington, DC, to explore medical and public health preparedness for a nuclear incident. The event brought together experts from government, nongovernmental organizations, academia, and the private sector to explore current assumptions behind the status of medical and public health preparedness for a nuclear incident, examine potential changes in these assumptions in light of increasing concerns about the use of nuclear warfare, and discuss challenges and opportunities for capacity building in the current threat environment. This publication summarizes the presentations and discussions from the workshop.

The present report is a revision of Safety Series No. 75-INSAG-3 (1988), updating the statements made on the objectives and principles of safe design and operation for electricity generating nuclear power plants. It includes the improvements made in the safety of operating nuclear power plants and identifies the principles underlying the best current safety policies to be applied in future plants. It presents INSAG's understanding of the principles underlying the best current safety policies and practices of the nuclear power industry.

This book appraises the current understanding of nuclear power plant accidents and the challenges posed to emergency planners. The contributors address the crucial need for real-time monitoring of both the development of the accident and the dispersion of radiation into the atmosphere.

In this book, compelling case studies show how past crises have reshaped regulation, and how policy-makers can learn from crises in the future.

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.

A concise and current treatment of the subject of nuclear power safety, this work addresses itself to such issues of public concern as: radioactivity in routine effluents and its effect on human health and the environment, serious reactor accidents and their consequences, transportation accidents involving radioactive waste, the disposal of radioactive waste, particularly high-level wastes, and the possible theft of special nuclear materials and their fabrication into a weapon by terrorists. The implementation of the defense-in-depth concept of nuclear power safety is also discussed. Of interest to all undergraduate and graduate students of nuclear engineering, this work assumes a basic understanding of scientific and engineering principles and some familiarity with nuclear power reactors

Accident analysis is an important tool for confirming the adequacy and efficiency of provisions within the defence in depth concept for the safety of nuclear power plants (NPPs). The purpose of the report is to provide the necessary practical guidance for performing adequate accident analysis in the light of current good practice worldwide.

This publication provides a practical resource for emergency planning, and fulfils, in part, functions assigned to the IAEA in the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency. If used effectively, it will help users to develop a capability to adequately respond to a nuclear or radiological emergency.
