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...

This IAEA-WHO framework serves as an invaluable resource for countries in their ongoing efforts to strengthen their capacity for cancer control. Sharing the expertise of professionals from around the globe, it comprehensively outlines the fundamental principles of multidisciplinary cancer care. Additionally, it provides detailed descriptions of the essential infrastructure, human resources, and equipment necessary to deliver various cancer services. The purpose of this publication is to pr...

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 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,...

Decommissioning is a complex stage in research reactor projects, the safe and efficient implementation of which can be greatly facilitated if it is considered from the early stages and throughout the project’s lifespan. This publication provides guidance on facilitating decommissioning during the design, construction and operation stages of a research reactor’s lifetime, and on managing objectives and requirements during the transition period. It presents good practices and lessons learned...

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...

The objective of this Safety Report is to provide information on the implementation of IAEA Safety Standards Series SSG-48, to support the ageing management and preparation for the safe, long-term operation of a nuclear power plant. It addresses ageing management of active and passive structures and components for water moderated reactors that can have an effect, directly or indirectly, on the safe operation of the plant and that are susceptible to ageing. This publication is intended for ...

Containment barrier systems are among the most widely used technologies for remediating contaminated sites. Various structures have been engineered to address site-specific needs, while barrier selection depends largely on whether regulatory requirements are prescriptive, or performance based. This publication provides an introduction to the design and construction of different containment barriers for low-level radioactive waste generated from remediation activities: basal (bottom) liners...

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...
