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 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.

Design of Nuclear Installations Against External Events Excluding Earthquakes by IAEA Pdf

This Safety Guide provides recommendations on the design of nuclear installations for protection against the effects of external events (excluding earthquakes), meeting the applicable safety requirements established in relation to the design aspects of nuclear installations subjected to external events. It provides methods and procedures for defining an appropriate design for a nuclear installation, based on the site hazard evaluation and the layout of the installation. The aim is to provide design guidance, in particular for the protection of structures, systems and components important to safety against design basis external events. The guide also provides recommendations on the selection of beyond design basis external events, in order to check and verify safety margins.

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.

Consideration of External Events in the Design of Nuclear Facilities Other Than Nuclear Power Plants, with Emphasis on Earthquakes by Anonim Pdf

This document aims to provide guidelines for the assessment of the safety of nuclear facilities other than NPPs in relation to external events through the application of simplified methods and procedures for their siting and design. The approach adopted is both simplified and conservative compared with that used for power reactors. It seeks to provide a rational balance for a suitable combination of sustainable effort in site investigations and refinement in design procedures, compatible with the assigned safety objectives, graded from the NPPs' ones. This publication is the offspring of IAEA-TECDOC-348 (1985) that focused on the seismic design of nuclear facilities with limited radioactive inventory. After some 17 years, new operational data have become available, sophisticated design methodologies are now more easily obtainable, and experts felt that the trade-off between sustainable investment in the facilities and design conservatism had to be redefined. The document was mainly developed for engineers, constructors and utilities, but it can be effectively applied also by regulatory bodies as a quick and conservative review tool.

External Man-induced Events in Relation to Nuclear Power Plant Design by International Atomic Energy Agency Pdf

This guide advises on the protection of nuclear power plants against the effects of external man-induced events which originate outside the site and which have been identified and selected as design basis external man-induced events (DBEMIEs) according to Safety Guide No. 50-SG-S5, to which this guide is complementary.

Design Extension Conditions and the Concept of Practical Elimination in the Design of Nuclear Power Plants by IAEA Pdf

The objective of this Safety Guide is to provide recommendations for the design of new nuclear power plants related to defense in depth and the practical elimination of plant event sequences that could lead to an early radioactive release or a large radioactive release. It also provides recommendations in relation to design aspects of defense in depth, in particular on those aspects associated with design extension conditions. Since the introduction of the term "practical elimination" in the early 90's and the recognition that accident conditions could include design extension conditions without significant fuel degradation and design extension conditions with core melting, those topics have been the subject of extensive discussions and several publications. The purpose of this publication is to facilitate international consensus on the understanding of those topics among regulators and designers and to provide recommendations for their consistent implementation in relevant nuclear power plant designs. In particular, this Specific Safety Guide gives recommendations related to the demonstration of the implementation of the practical elimination concept for those plant event sequences that could lead to an early radioactive release or a large radioactive release, which relies on the physical impossibility or on the high-level confidence that they are extremely unlikely to arise.

The Risks of Nuclear Energy Technology by Günter Kessler,Anke Veser,Franz-Hermann Schlüter,Wolfgang Raskob,Claudia Landman,Jürgen Päsler-Sauer Pdf

The book analyses the risks of nuclear power stations. The security concept of reactors is explained. Measures against the spread of radioactivity after a severe accident, accidents of core melting and a possible crash of an air plane on reactor containment are discussed. The book covers three scientific subjects of the safety concepts of Light Water Reactors: – A first part describes the basic safety design concepts of operating German Pressurized Water Reactors and Boiling Water Reactors including accident management measures introduced after the reactor accidents of Three Mile Island and Chernobyl. These safety concepts are also compared with the experiences of the Fukushima accidents. In addition, the safety design concepts of the future modern European Pressurized Water Reactor (EPR) and of the future modern Boiling Water Reactor SWR-1000 (KERENA) are presented. These are based on new safety research results of the past decades. – In a second, part the possible crash of military or heavy commercial air planes on reactor containment is analyzed. It is shown that reactor containments can be designed to resist to such an airplane crash. – In a third part, an online decision system is presented. It allows to analyze the distribution of radioactivity in the atmosphere and to the environment after a severe reactor accident. It provides data for decisions to be taken by authorities for the minimization of radiobiological effects to the population. This book appeals to readers who have an interest in save living conditions and some understanding for physics or engineering.
