This Safety Guide provides guidance and recom m endations on surveillance activities to ensure that structures, systems and com ponents im portant to safety are available to perform their functions in accordance w ith design intent and assumptions. The Guide was prepared as part of the IAEA’s programme, referred to as the NUSS Programme, for establishing Codes of Practice and Safety Guides re…
Nuclear power plants of the light water reactor (LWR) type are so designed and operated that no accident reasonably considered to be possible would release significant amounts of fission products to the environment. It follows that rare improbable events such as severe accidents would provide the only potentially significant contribution to adverse human health effects. The potential for such s…
This Safety Guide was prepared as part of the Agency’s programme, referred to as the NUSS programme, for establishing Codes o f Practice and Safety Guides relating to nuclear power plants. It supplements the Code of Practice on Safety in Nuclear Power Plant Operation, including Commissioning and Decommissioning (IAEA Safety Series No. 50-C-0), hereinafter referred to as the Code. The Provisio…
This report provides information on the content and format for decommissioning plans and supporting safety related documents. Its scope includes information that is relevant to all types of nuclear facilities, ranging from nuclear power plants and reprocessing facilities to university laboratories and manufacturing plants. The report will be of interest to decommissioning planning engineers, pr…
This Safety Guide discusses the phenomena, both natural and human induced, that may cause floods or droughts at coastal and river sites, and gives an outline of the methods that can be used for, and the critical factors involved in, the evaluation of such events and of their associated effects. Possible combinations of two or more phenomena that can give rise to flooding at a site are also disc…
This Safety Guide was prepared as part of the Agency's programme for establishing Codes and Safety Guides relating to nuclear power plants. The main purpose of the text is to provide guidance on the determination of the design basis ground motions for a nuclear power plant at a chosen site and on the determination of the potential for surface faulting at that site. Additionally, the Guide discu…
The systems which perform the vitai functions of monitoring and controlling systems and parameters at nuclear power plants are known as instrumentation and control (I&C) systems*. They are divided into two types: information systems and control systems. Both types operate by providing signals from measuring equipment. Information systems monitor plant parameters and systems; they display and…
Identifies the typical parameters of a component that permit it to be characterized unequivocally and to allow the corresponding reliability data to be associated with those of other components having equivalent typical parameters. Parameters refer to technical characteristics including the physical principle of operation and quality level and to actual operating conditions and maintenance and …
This Safety Guide provides guidance on the development, content and use of operational limits and conditions (limits on plant operating parameters) and operating procedures that affect them. It recommends how to meet the requirements established in Safety Standards Series No. NS-R-2, Safety of Nuclear Power Plants: Operation, setting out the responsibilities of the operating organization in set…
