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...

This Safety Guide identifies the main objectives and responsibilities of the operating organization for the recruitment, qualification and training of personnel for new and existing nuclear power plants to establish and maintain a high level of competence of personnel and to ensure safe operation of the nuclear power plant. This publication can also be used as a guide for the recruitment, training and qualification of personnel for nuclear installations other than nuclear power plants.

This publication is one of the series of IAEA publications on the environmental behaviour of naturally occurring radionuclides. It outlines uranium behaviour in different environments, as well as its transfer to, and metabolism in, humans. The publication also provides concepts, models and data required for the assessment of the impacts of uranium on non-human biota. Assessing the environmental and health effects of uranium poses specific challenges because of the combination of different ...

This Safety Guide provides recommendations on geotechnical engineering aspects that are important to the safety of nuclear installations, such as site investigation planning, evaluation of geotechnical hazards, considerations for design and analyses, monitoring of geotechnical parameters, and the application of a graded approach to geotechnical evaluations for nuclear installations other than large nuclear power plants, excluding nuclear waste disposal facilities. This publication is inten...

This publication developed by the International Nuclear Safety Advisory Group (INSAG) supplements its advice provided in INSAG-10 underscoring application of the principle of defence in depth in nuclear safety for small modular reactors and related emerging technologies. It is intended to stimulate discussion and to promote practical action at all levels to enhance safety of Small Modular Reactors (SMRs). INSAG provides recommendations on current and emerging nuclear safety issues to the I...

Within the nuclear field, a vast body of knowledge, involving scientific, technical and managerial fields, is distributed among many organizations of different types. Managing and provisioning distributed knowledge is therefore becoming one of the major challenges in federated organizational environments. This publication provides information to organizations dealing with nuclear knowledge and its management. It covers an introduction to semantic information technologies, the Worldwide Web...

The focus of this publication is on the activities required to demonstrate the suitability of commercial off the shelf (COTS) digital instrumentation and control equipment for use in nuclear safety applications. The publication provides a detailed discussion of the typical challenges associated with the use of COTS devices, including issues associated with unique vulnerabilities and features of digital products. It outlines the strategy for digital COTS device assessment and qualification ...

This Safety Guide provides practical guidance and recommendations on ageing management for research reactors, to meet the relevant requirements of IAEA Safety Standards Series No. SSR-3, Safety of Research Reactors. It is intended for use by operating organizations in establishing, implementing and improving ageing management programmes for research reactors, and by regulatory bodies in verifying that ageing of research reactors is being effectively managed. The Safety Guide focuses on man...

This Safety Guide provides recommendations on the safe disposal of disused sealed radioactive sources in borehole disposal facilities. Sealed radioactive sources are used all over the world for a wide range of purposes, in areas such as health, industry, research and agriculture. These sources are usually managed safely while in use, but States often experience challenges in their management once the sources reach the end of their useful lives. Even though they may no longer emit sufficien...

This publication provides an introduction to the management of research reactor spent nuclear fuel (RRSNF). Five key areas are discussed: types of RRSNF, characterization data, wet storage considerations, dry storage considerations, and lessons learned and current practices. Information on internationally accepted standards as well as information on aspects such as drying treatment and surveillance programmes are presented, as well as suggestions for further optimization of effective and s...

Research reactor fuel technology continues to evolve, driven in part by international efforts to develop high density fuels to enable the conversion of more reactors from highly enriched uranium (HEU) to low enriched uranium (LEU) fuels. These high density fuels may offer economic benefits for research reactors, despite being more expensive initially, because they offer the prospect of higher per-assembly burnup, thus reducing the number of assemblies that must be procured, and more flexib...

This publication is part of a series that aims to inform nuclear facility designers, vendors, operators and State governments about IAEA safeguards and how associated requirements can be considered early in the design phase of a new nuclear facility. This particular publication is applicable to the design and construction of commercial uranium enrichment plants. Safeguards by design dialogue undertaken early in the design and construction of enrichment plants facilitates the implementation...
