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 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.

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.

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.

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.

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.
