This Safety Guide presents the safety principles and the approach underlying the design of nuclear pow er plants and identifies the relationship between the Code of Practice on Design for Safety of Nuclear Power Plants (IAEA Safety Series 50-C-D, hereafter referred to as the Code) and other Guides in the design. area of the NUSS Programme. It should be read as an elaboration of the safety princ…
The Country Nuclear Power Profiles (CNPP) publication compiles background information on the status and development of nuclear power programmes across participating International Atomic Energy Agency (IAEA) Member States. The publication summarizes organizational and industrial aspects of nuclear power programmes and provides information about the relevant legislative, regulatory and internatio…
The requirement of deriving design extension conditions (DEC), which are understood to comprise both conditions in events without significant fuel degradation and conditions in events with core melting, were introduced in IAEA Safety Standards Series No. SSR-2/1 (Rev. 1), Safety of Nuclear Power Plants: Design [1]. In SSR-2/1 (Rev. 1) [1], DEC were introduced for the purpose of further improvin…
Given the increasing interest of Member States in the near term deployment of SMRs, this publication presents several model technology roadmaps that States can adapt for their specific projects. For nuclear newcomer countries, these roadmaps assume that a Member State has already developed, or is at least well along the way to developing, the infrastructure necessary to carry out a nuclear powe…
The objective of this publication is to provide specific guidance for accident analysis for nuclear power plants with pressurized water reactors, taking into account the specific design features of these reactors. This guidance covers all steps required to perform such analyses, including selection of initiating events, acceptance criteria, computer codes, modelling assumptions, preparation of …
The objective of this report is to facilitate a recognition of priority management issues which, when not adequately recognized and addressed, can result in problems in operational performance at nuclear power plants. It provides a number of effective practices, reflecting the positive experience of nuclear power companies, that have prevented or corrected problems related to selected managemen…
This Guide describes the first stage of the siting process for nuclear power plants — the site survey, which involves the study and investigation of a large region to select one or more preferred candidate sites. Its purpose is to recommend procedures and provide information for use in implementing a part of the Code of Practice on Safety in Nuclear Power Plant Siting (IAEA Safety Series No. …
Asset management plays an important role in maintaining the competitiveness of nuclear power plants in a challenging and changing electricity market. The value of effective asset management is in providing support to those making decisions seeking the optimum level of financial performance, operational performance and risk exposure. This publication provides information on various methodologies…
The hydrosphere represents an important pathway by which radioactive materials caft be dispersed from a nuclear power plant into the environment and hence to man. The dispersion in surface water is discussed in this Guide while the question of dispersion in groundwater is presented in the Safety Guide on Nuclear Power Plant Siting: Hydrogeologic Aspects (IAEA Safety Series No.50-SG-S7).
This Safety Guide provides recommendations on how to meet the requirements of IAEA Safety Standards Series No. SSR-2/1 (Rev. 1), Safety of Nuclear Power Plants: Design, in relation to fuel handling and storage systems. The publication addresses the design aspects of handling and storage systems for fuel that remain part of the operational activities of a nuclear reactor. It covers the following…
