Book Seismic Design and Qualification for Nuclear Power Plants

Download or read book Seismic Design and Qualification for Nuclear Power Plants written by International Atomic Energy Agency and published by IAEA. This book was released on 2003 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Safety Guide provides recommendations on a generally accepted way to design a nuclear power plant so that an earthquake motion at the site will not jeopardize the safety of the plant. It also gives guidance on a consistent application of methods and procedures for analysis, testing and qualification of structures and equipment so that they meet the safety requirements covering the design of nuclear power plants, safety assessments for the design and the regulatory issues concerned with the licensing of plants.

Book Seismic Evaluation of Safety Systems at the Savannah River Reactors

Download or read book Seismic Evaluation of Safety Systems at the Savannah River Reactors written by and published by . This book was released on 1989 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thorough review of all safety related systems in commercial nuclear power plants was prompted by the accident at the Three Mile Island Nuclear Power Plant. As a consequence of this review, the Nuclear Regulatory Commission (NRC) focused its attention on the environmental and seismic qualification of the industry's electrical and mechanical equipment. In 1980, the NRC issued Unresolved Safety Issue (USI) A-46 to verify the seismic adequacy of the equipment required to safely shut down a plant and maintain a stable condition for 72 hours. After extensive research by the NRC, it became apparent that traditional analysis and testing methods would not be a feasible mechanism to address this USI A-46 issue. The costs associated with utilizing the standard analytical and testing qualification approaches were exorbitant and could not be justified. In addition, the only equipment available to be shake table testing which is similar to the item being qualified is typically the nuclear plant component itself. After 8 years of studies and data collection, the NRC issued its ''Generic Safety Evaluation Report'' approving an alternate seismic qualification approach based on the use of seismic experience data. This experience-based seismic assessment approach will be the basis for evaluating each of the 70 pre-1972 commercial nuclear power units in the United States and for an undetermined number of nuclear plants located in foreign countries. This same cost-effective developed for the commercial nuclear power industry is currently being applied to the Savannah River Production Reactors to address similar seismic adequacy issues. This paper documents the results of the Savannah River Plant seismic evaluating program. This effort marks the first complete (non-trial) application of this state-of-the-art USI A-46 resolution methodology.

Book IEEE Standard for Seismic Qualification of Equipment for Nuclear Power Generating Stations

Download or read book IEEE Standard for Seismic Qualification of Equipment for Nuclear Power Generating Stations written by and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Practices are provided for establishing procedures that will yield data to demonstrate that the equipment can meet its performance requirements during and/or following one safe shutdown earthquake event preceded by a number of operating basis earthquake events. This standard may be used to establish tests, analyses, or experienced-based evaluations that will yield data to demonstrate equipment performance claims or to evaluate and verify performance of devices and assemblies as part of an overall qualification effort. Common methods currently in use for seismic qualification by test are presented. Two approaches to seismic analysis are described, one based on dynamic analysis and the other on static coefficient analysis. Two approaches to experienced-based seismic evaluation are described, one based on earthquake experience and the other based on test experience. Keywords: earthquake, earthquake experience, equipment qualification, IEEE 344, inclusion rules, nuclear, operating basis earthquake, prohibited features, qualification methods, required response spectrum, response spectra, safe shutdown earthquake, safety function, seismic, seismic analysis, test experience, test response spectrum, type testing.

Book Methodologies for Seismic Safety Evaluation of Existing Nuclear Installations

Download or read book Methodologies for Seismic Safety Evaluation of Existing Nuclear Installations written by IAEA and published by International Atomic Energy Agency. This book was released on 2020-08-26 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Equipment Qualification in Operational Nuclear Power Plants

Download or read book Equipment Qualification in Operational Nuclear Power Plants written by International Atomic Energy Agency and published by . This book was released on 1998 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is based on information presented at two IAEA Technical Committee meetings held within the framework of the IAEA Project on Operational Safety Guidance in 1993 and 1994. The document was prepared to provide guidance to Member States in assessing the status of equipment qualification (EQ) in operational nuclear power plants and in preserving this status. It offers methods and practices for activities which are necessary for a successful implementation of periodical safety reviews. The report should be of value for all countries that are parties to the Convention on Nuclear Safety, which entered into force on 24 October 1996 and stipulates the review and, where necessary, the upgrading of the safety of existing nuclear installations.
