Accident Analysis for Nuclear Power Plants with Graphite Moderated Boiling Water RBMK Reactors


Book Description

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. This publication contains guidance on the specific design features of graphite moderated boiling water reactors (RBMKs), including advice regarding categorisation of initiating events, selection of acceptance criteria, and initial and boundary conditions.







The Chernobyl Accident


Book Description

The INIS Reference Series defines the rules, standards, formats, codes and authority lists on which the International Nuclear Information System is based. Over the years most manuals have been revised or merged, and further revisions will be issued in the future. The series consists of 10 current manuals, all of which are available in print, on microfiche and many in electronic form, as described below. The Thesaurus gives the Spanish translation of the controlled vocabulary to be used by INIS members to index the literature they report to INIS. This authority ensures consistent subject indexing. Revision 32 of the Spanish version contains 19 422 accepted terms (descriptors) and 6065 forbidden terms (non-descriptors). The terms are listed alphabetically in Spanish, followed by the English equivalent, and with each alphabetic entry a 'word block' containing all the terms associated with that particular entry is displayed.




The Technological and Economic Future of Nuclear Power


Book Description

This open access book discusses the eroding economics of nuclear power for electricity generation as well as technical, legal, and political acceptance issues. The use of nuclear power for electricity generation is still a heavily disputed issue. Aside from technical risks, safety issues, and the unsolved problem of nuclear waste disposal, the economic performance is currently a major barrier. In recent years, the costs have skyrocketed especially in the European countries and North America. At the same time, the costs of alternatives such as photovoltaics and wind power have significantly decreased.




Thermal-Hydraulics of Water Cooled Nuclear Reactors


Book Description

Thermal Hydraulics of Water-Cooled Nuclear Reactors reviews flow and heat transfer phenomena in nuclear systems and examines the critical contribution of this analysis to nuclear technology development. With a strong focus on system thermal hydraulics (SYS TH), the book provides a detailed, yet approachable, presentation of current approaches to reactor thermal hydraulic analysis, also considering the importance of this discipline for the design and operation of safe and efficient water-cooled and moderated reactors. Part One presents the background to nuclear thermal hydraulics, starting with a historical perspective, defining key terms, and considering thermal hydraulics requirements in nuclear technology. Part Two addresses the principles of thermodynamics and relevant target phenomena in nuclear systems. Next, the book focuses on nuclear thermal hydraulics modeling, covering the key areas of heat transfer and pressure drops, then moving on to an introduction to SYS TH and computational fluid dynamics codes. The final part of the book reviews the application of thermal hydraulics in nuclear technology, with chapters on V&V and uncertainty in SYS TH codes, the BEPU approach, and applications to new reactor design, plant lifetime extension, and accident analysis. This book is a valuable resource for academics, graduate students, and professionals studying the thermal hydraulic analysis of nuclear power plants and using SYS TH to demonstrate their safety and acceptability. - Contains a systematic and comprehensive review of current approaches to the thermal-hydraulic analysis of water-cooled and moderated nuclear reactors - Clearly presents the relationship between system level (top-down analysis) and component level phenomenology (bottom-up analysis) - Provides a strong focus on nuclear system thermal hydraulic (SYS TH) codes - Presents detailed coverage of the applications of thermal-hydraulics to demonstrate the safety and acceptability of nuclear power plants




Radiological Characterization of Shut Down Nuclear Reactors for Decommissioning Purposes


Book Description

This report describes and assesses radiological characterization as a precursor to decommissioning. It shows the influence of the radioactive inventory on the planning and strategies of decommissioning and also presents an extensive overview of characterization results on various reactors which have been or are being decommissioned.




Safety Margins of Operating Rectors


Book Description

This TECDOC deals with a basic concept of safety margins and their role in assuring safety of nuclear Installations. The document describes capabilities of thermal hydraulic computer codes used to determine safety margins, evaluation of uncertainties, methods for safety margin evaluation and utilization of safety margins in operation and modifications of nuclear power plants.




Experience Gained from Fires in Nuclear Power Plants


Book Description

Offers a detailed analysis of the most recent events collected in IAEA databases and other bibliographical sources. The publication provides the technical background for the recently revised IAEA Safety Guide on fire protection and a collection of lessons learned useful for practical fire safety enhancement in operating plants.




Environmental Consequences of the Chernobyl Accident and Their Remediation


Book Description

The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.




Processing of Irradiated Graphite to Meet Acceptance Criteria for Waste Disposal


Book Description

Graphite is widely used in the nuclear industry and in research facilities and this has led to increasing amounts of irradiated graphite residing in temporary storage facilities pending disposal. This publication arises from a coordinated research project (CRP) on the processing of irradiated graphite to meet acceptance criteria for waste disposal.
