This publication documents the results of an IAEA coordinated research project (CRP)on the application of computational fluid dynamics (CFD) codes for nuclear power plant design. The main objective was to benchmark CFD codes, model options and methods against CFD experimental data under single phase flow conditions. This publication summarizes the current capabilities and applications of CFD codes, and their present qualification level, with respect to nuclear power plant design requirements. It is not intended to be comprehensive, focusing instead on international experience in the practical...

This Safety Guide provides specific recommendations on protection against internal and external hazards in the operation of nuclear power plants. It provides new or updated recommendations derived from enhanced understanding of operational aspects of hazards and combinations of hazards. Operating experience gained from incidents and accidents in nuclear power plants around the world has demonstrated that fire can be an important risk contributor in many Member States. However, there are other internal and external hazards that have also to be considered in the design and operation of nuclear...

As an integral part of the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO), several collaborative projects were established by its members. The IAEA/INPRO Collaborative Project on Environmental Impact Benchmarking Applicable for Nuclear Energy Systems under Normal Operation (ENV) was one of them. This publication is the outcome of the ENV summarising results developed under this project by the groups of national experts. It presents a set of examples of different approaches for estimating environmental impact from nuclear power plants (NPPs) under normal operation...

Engaging in a nuclear power programme is a major undertaking with long term implications for at least hundred years. Key factors that may influence decision makers in their commitment to a nuclear power programme are of different nature, including political, socio-economic, financial, environmental, technical, or public acceptance. In line with the guidelines of the IAEA Milestones Approach, a comprehensive report corresponds to the attainment of Milestone I (ready to make a knowledgeable commitment to a nuclear power programme) and provides the rationale and strategy for pursuing a nuclear...

This INSAG report defines in detail the independence needed in the regulatory decision making process and how to meet the potential challenges to that independence. Thus, the report identifies a number of measures that need to be implemented at different levels to promote and protect independence in the regulatory decision making process. The basic principles have to be embedded into the legal framework and followed up by systematic quality management of regulatory processes and activities.

To assure the safe, technically optimal and cost effective management of spent fuel and radioactive waste, appropriate policies and strategies are required. This publication clarifies the differences between a policy and a strategy, and provides principal advice to Member States on the typical composition, mutual links and the process of compilation of such documents. It also offers options for and indicates approaches to the management of spent fuel and radioactive waste, thus enabling an effective spent fuel and radioactive waste management infrastructure to be developed.

This Safety Guide provides guidance on the implementation of the requirements in the International Basic Safety Standards, IAEA Safety Standards Series No. GSR Part 3, in relation to protection of the public and the environment against radiation risks. It provides generic guidance on the application of the radiation protection principles of justification, of optimization of protection and safety, and of dose limits. The publication covers the protection of the public and the environment in all exposure situations - planned, emergency and existing.
