This publication explores how advanced instrumentation and control (I&C) systems and digital technologies can enhance nuclear power plant performance across critical attributes, such as availability, operational flexibility, engineering efficiency and environmental sustainability. It offers an up-to-date overview of proven practices, innovative approaches and lessons learned throughout the plant life cycle, from design and construction to operation and long-term management. Developed to su...

The terms for describing advanced nuclear power plants (NPPs) need to conform to the broad, general, common understanding by the public as well as by the technical community. This publication is a revision of IAEA-TECDOC-936 incorporating developments and initiatives since 1997 in the areas of advanced, evolutionary, and innovative nuclear reactor designs, description of design development phases, inclusive of relevant safety and regulatory terminology, consistent with current IAEA safety ...

Since its establishment in September 2003, the International Expert Group on Nuclear Liability (INLEX) has played an important role in raising awareness and understanding of the nuclear liability instruments adopted under the IAEA’s auspices. Over the course of the past two decades, the group has advised on many issues related to nuclear liability and reached conclusions and made recommendations on possible gaps and ambiguities in the scope and coverage of the existing instruments. To mark...

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 requiremen...

In this publication the basic principles of radiation physics, imaging and non-imaging instrumentation used, measurement of the administered activity, calibration procedures and methods for obtaining quantitative information on the biodistribution of the radioactive drug to be used with radioisotopes relevant to therapy are specified. It also describes methods for segmentation and registration of images acquired at different time points, strategies for fitting and integration of activity m...

Radiation sources used in research and education include particle accelerators, sealed radioactive sources, such as low activity check sources and high activity sealed radioactive sources in irradiators; unsealed radioactive sources that are used as tracers in field work and in laboratory work; naturally occurring radioactive material and X ray generators such as diffraction apparatus and fluorescence analyzers. This Safety Guide provides recommendations on how to meet the relevant require...

Protection of the environment is one of the cornerstones of sustainable development, a key consideration for Member States embarking on new nuclear power programs. National requirements and international instruments increasingly reflect this concern and for the provision of opportunities for interested parties and stakeholders to be involved in decision-making processes. This new edition provides valuable guidance to Member States on issues related to environmental protection when consider...

This Safety Guide provides recommendations on the protection of workers against exposure due to radon in existing exposure situations and planned exposure situations. It focuses on the identification of workplaces of concern and the implementation of requirements for radiation protection through the application of a graded approach and the principles of justification and optimization of protection and safety. This includes exposure in workplaces such as buildings, underground locations and...

Cost-Benefit Analysis (CBA) is an economic appraisal tool which can be used to inform an investment decision, for instance, the construction of a nuclear power plant. In a CBA, the costs and benefits are accounted for as fully as possible, allowing estimation of the net economic benefit associated with the project relative to a without-the-project scenario, or an alternative investment proposal. This publication suggests an approach for conducting a CBA for a nuclear newbuild project as pa...

Each package used for the transport of radioactive material must demonstrate compliance with the IAEA Regulations for the Safe Transport of Radioactive Material, IAEA Safety Standards Series No. SSR-6, particularly for international shipments. This new safety guide provides recommendations to support compliance with the requirement related to the ageing of transport packages, specifically addressing ageing management and maintenance. The guide applies to all package types containing radioa...

This publication examines the historical and current use of SLOWPOKE (Safe Low Power Critical Experiment) and miniature neutron source reactor (MNSR) research reactors. It discusses known issues, considers the potential for future challenges and opportunities, and provides information on their history, development, utilization, operational experience, core conversion and refuelling, ageing management and decommissioning. The Annex includes abstracts of 17 papers, available online, covering...

The objective of this publication is to describe the state of the art framework of human reliability analysis (HRA) with a detailed description of HRA procedures and factors to be considered in the process of an HRA. It is intended to be applied for both new and existing nuclear installations. This publication is intended to be used by a broad spectrum of analysts, for example probabilistic safety assessment (PSA) practitioners and human factor engineers, as well as regulatory bodies, util...
