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...

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...

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...

This Safety Guide provides recommendations for ensuring radiation protection in the design of new nuclear power plants, design modifications to operating plants, and checking the adequacy of the radiation protection aspects of design at different stages in the lifetime of operating plants. It also provides recommendations for measures to be taken in the design for the protection of site personnel, the public and the environment, and outlines the methodologies used to calculate on-site and ...

Nuclear energy and renewables are the two principal options for low carbon energy generation. However, synergies among these resources have yet to be fully exploited, and the advantages of directly integrating these generation options are being explored. Nuclear-renewable hybrid energy systems consider opportunities to couple these energy generation sources to leverage the benefits of each technology to provide reliable, sustainable electricity to the grid and to provide low carbon energy ...

This publication provides detailed guidance to States and their competent authorities on how to implement and maintain a nuclear security regime for the transport of nuclear and other radioactive material. The publication builds upon relevant recommendations in NSS No. 13 and NSS No. 14 and provides additional explanations of how to implement these recommendations in practice. This publication is intended for nuclear security regulatory bodies and may also be useful to operators, shippers,...

The brachytherapy process requires consistent reference dosimetry that is traceable to metrological primary standards and common procedures to be followed for reference dosimetry globally. The Code of Practice is addressed to both Secondary Standards Dosimetry Laboratories and hospitals. It fulfills the need for a systematic and internationally unified approach to the calibration and use of vented well-type re-entrant ionisation chambers in determining the strength of brachytherapy sources...

This publication provides guidance on planning, implementing, and evaluating systems and measures in a State in order to detect nuclear and other radioactive material out of regulatory control in the State’s interior by means of instrument alarms and information alerts. The guidance covers the planning of detection operations, equipment deployment and human resource development. This publication is intended for authorities responsible for designing, implementing, and sustaining nuclear sec...

Improved fuel reliability means reduced fuel failures in reactor operation. Fuel failures, with their consequent adverse impact on the environment and requirements for additional waste management, result in costs for remediation, 'failed core' operation and maintenance. Therefore, poor performance of fuel can lead to uncompetitive operational conditions for a nuclear power plant. A revision of the earlier edition, this publication has been significantly extended to support nuclear fuel des...

This publication provides detailed information for operating organizations of research reactors on methodologies to manage existing and potential ageing effects and the degradation of structures, systems and components. Practical guidance is presented on managing the effects of ageing on civil structures, on mechanical, electrical and instrumentation and control systems, and on reactor components important for safety and operation. This publication also provides information on how to estab...

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...
