Assessment of Vulnerabilities of Operating Nuclear Power Plants to Extreme External Events by International Atomic Energy Agency Pdf
The Fukushima Daiichi accident showed the need to explore scenarios where external hazards exceed the design basis. Knowledge of plant behaviour along those scenarios helps improve global safety, since the weak points can be identified and measures to limit the progression of potential accidents or to mitigate their consequences can be introduced. Based on an IAEA methodology document for Member States issued in 2011, the current publication expands the previous version by giving a more comprehensive approach and introducing the enhancements that could be identified from the research developments and practical applications in the recent years.
Nuclear Power Plant Security and Vulnerabilities by Mark Holt Pdf
The physical security of nuclear power plants (NPP) and their vulnerability to acts of terrorism was elevated to a national security concern following the 9/11 attacks. Since then, Congress has focused oversight and legislative attention on NPP security requirements. The Energy Policy Act of 2005 act required NRC to conduct ¿force-on-force¿ security exercises at NPP at least once every 3 years. In these exercises, a mock adversary force from outside a NPP attempts to penetrate the plant¿s vital area and simulate damage to key safety components. Contents of this report: Overview of Reactor Security; Design Basis Threat; Large Aircraft Crashes; Force-On-Force Exercises; Emergency Response; Spent Fuel Storage; and Security Personnel.
Safety Aspects of Nuclear Power Plants in Human Induced External Events by International Atomic Energy Agency Pdf
This publication gives the general roadmap on how to perform the design and evaluation of the protection of nuclear power plants against human induced external hazards, consistent with IAEA Safety Standards. The publication concentrates on an overall view of the methodology and on the important considerations for its application to existing and new nuclear power plants. Topics covered include elements of the design/evaluation approach, developed in five phases: event identification; load characterization; design and assessment approaches; plant performance assessment and acceptance criteria; and operator response. The publication provides an approach to the assessment of extreme human induced external events which is fully consistent with the methods used for evaluation of nuclear facilities subjected to extreme natural events, such as earthquakes and floods.
Extreme External Events in the Design And Assessment of Nuclear Power Plants by International Atomic Energy Agency Pdf
The objective of this publication is to provide a technical background to assist regulators, plant owners and designers in the definition of a consistent strategy in selected safety issues on site evaluation, design and operation in relation to extreme external events. The publication is also of assistance to the IAEA in the development of the Safety Series programme, where many safety guides dealing with related topics are under periodic review. Emphasis is given to the generally accepted "risk based" context, where the probability of event occurrence is analysed together with the probability of an induced radiological consequence. The publication intends to solve the pending issues that prevent a full scope application of the approach in relation to the external events. The relevant differences among the practices in Member States are analysed through a questionnaire. Many proposals for a consensus on the main safety issues are developed and presented in detail.
Safety Aspects of Nuclear Power Plants in Human Induced External Events by International Atomic Energy Agency Pdf
This publication describes the procedures for calculating the margins of nuclear power plants in relation to human induced external hazards. It focuses on plant and systems performance evaluations. A two level approach for margin assessment is provided. The first level consists of a deterministic procedure in which, for each scenario, the existence of at least one undamaged success path to comply with the fundamental safety function is investigated. This procedure can be subsequently extended to calculate probability measures such as conditional core damage probability and the conditional probability of spent fuel damage. In the most elaborated stage, probabilistic safety assessment (PSA) techniques are introduced, giving consideration to the probabilistic aspects of the hazards and of the capacity of structures, systems and components (fragility). Event tree and fault tree models are used to compute PSA metrics, such as core damage frequency, large-early release frequency and frequency of spent fuel damage.

Engineering Safety Aspects of the Protection of Nuclear Power Plants Against Sabotage by International Atomic Energy Agency Pdf
The result of extensive dialogue among safety and security specialists, this report provides guidelines for evaluating the engineering safety aspects of the protection of nuclear power plants against sabotage. The guidance takes into account the existing robustness of structures, systems and components, and emphasizes those aspects of sabotage protection that work synergistically with the protection against extreme external occurrences of accidental origin, such as earthquakes, tornadoes and human induced events. The report introduces a defense approach to sabotage protection, with layers comprising safety and security related systems and activities, and promotes self-assessment by the licensee in cooperation with the required interfaces with the competent authorities.--Publisher's description.
Methodologies for Seismic Safety Evaluation of Existing Nuclear Installations by IAEA Pdf
Experience shows that an assessment of the seismic capacity of an existing operating facility can be required for a number of reasons, for example identification of potential seismic vulnerabilities based on operating experience events or the periodic safety review programme. This publication covers the seismic safety evaluation programmes to be performed on existing nuclear installations in order to ensure that the required fundamental safety functions are available, with particular attention to the safe shutdown of reactors. It includes lessons learned based on the IAEA Action Plan on Nuclear Safety following the Fukushima Daiichi accident, and updated methodologies for seismic safety evaluation of nuclear installations.
Enhancing Nuclear Security Culture in Organizations Associated with Nuclear and Other Radioactive Material by IAEA Pdf
Nuclear security culture is an important component of an effective nuclear security regime, as it serves as a tool to improve the performance of the human component at nuclear facilities and organizations to counter both insider and outsider threats. Security culture connotes not only the technical proficiency of the people but also their awareness of security risks and motivation to follow established procedures, comply with regulations and take the initiative when unforeseen circumstances arise. A workforce made up of individuals who are vigilant, who question irregularities, execute their work diligently and exhibit high standards of personal and collective behaviour is able to achieve effective nuclear security. Building upon this understanding of the importance of a strong nuclear security culture, this publication provides practical guidance on how to implement a systematic nuclear security culture enhancement programme.

Lessons Learned from the Fukushima Nuclear Accident for Improving Safety of U.S. Nuclear Plants by National Research Council (U.S.). Committee on Lessons Learned from the Fukushima Nuclear Accident for Improving Safety and Security of U.S. Nuclear Plants,National Research Council,Nuclear and Radiation Studies Board,Division on Earth and Life Studies Pdf
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.
