<p class="MsoNormal">This publication is the outcome of a meeting of an
international team of experts that discussed various technical and scientific
details applicable to the production of important radionuclides such as ⁹⁹Mo,
copper-67 (⁶⁷Cu), scandium-47 (⁴⁷Sc) and actinium-225 (²²⁵Ac)
using the photonuclear route. This publication provides an overview of the
current state of methods for the photonuclear production of isotopes with a
particular focus on those medical radioisotopes that could be produced in
sufficient quantities for clinical use in nuclear medicine. It is intended for
scientists and technical professionals in the fields of electron accelerators
and radioisotope production. <span style="font-family:&quot;Arial&quot;,sans-serif"><o:p></o:p></span></p>

This publication provides an analysis of results from Integrated Safety Assessment of Research Reactors (INSARR) Missions conducted at research reactors during the period from 1995 to 2021. The analysis includes an assessment of trends, common issues, and other insights that are highly beneficial to Member States operating research reactors. This publication is also useful for self-assessment of research reactor safety. This publication is intended for use by operating organizations of research reactors, regulatory bodies and other relevant organizations involved in the safety of research reactors.

This outlook produced for the G20 under the Presidency of Brazil (2024) is written to inform the Energy Transitions Working Group (ETWG) within the G20 Sherpa Track as well as the wider international energy and climate change community. This publication provides an overview of the contribution of nuclear energy to global climate change mitigation pathways toward net zero, highlighting the investment requisites. Global mitigation scenario pathways disseminated by the Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA) indicate significantly more nuclear electricity – a doubling or more by 2050 – as a key part of the solution to limit global warming to the 1.5 and 2 degree goals of the Paris Agreement. Nuclear heat and hydrogen can also play a role in decarbonizing hard-to-abate activities in heavy industry and transportation. Unlocking and accelerating investment would be necessary for the rapid deployment of nuclear energy, including in emerging markets and developing economies. This calls for consistent climate, energy and investment policy frameworks — embracing a wide array of financing approaches — in tandem with efficient markets, effective project risk management and multi-stakeholder cooperation to accelerate annual nuclear energy investment to reach net zero. This publication presents key information and data to support and advise decision makers.

There is a growing societal awareness regarding the importance of regulatory systems for nuclear facilities and activities to have visible oversight of safety and security interfaces. This publication compiles relevant IAEA requirements, recommendations and guidance on identifying and addressing potential and actual interactions between nuclear safety and nuclear security systems and measures in nuclear power plants (NPPs). It also presents regulatory practices that are important to consider for nuclear safety and nuclear security, as they may reinforce or compromise the capacity of the regulatory bodies, competent authorities and operating organizations to meet nuclear safety and nuclear security requirements, including requirements relating to the interfaces between safety and security, during the application of regulatory functions in the various stages of the lifetime of an NPP.

The objective of this Safety Guide is to provide recommendations for meeting the requirements of GSR Part 4 (Rev. 1) in the development and application of Level 1 Probabilistic Safety Assessments (PSAs) for nuclear power plants (NPPs). The recommendations provided in this publication promoting technical consistency among Level 1 PSA studies, in order to provide reliable support for applications of PSAs and risk informed decision making, particularly to support the design of NPPs and decision making during plant commissioning and operation. The revised Safety Guide's scope encompasses the main methodological aspects of PSA and in particular has been updated to reflect developments in specific areas, such as passive systems reliability, computer based systems reliability, combinations of hazards, human reliability analysis and to expand the scope of PSA to include site level risk considerations such as multi-unit and spent fuel pool PSA.

This publication provides an overview of plasma physics and technology aspects of the Deuterium-Tritium fuel cycle in magnetic fusion devices, from ITER to demonstration fusion power plants. The TECDOC also provides contributed papers from experts representing a wide range of international magnetic confinement fusion research and development programmes working on the D-T fuel cycle. This publication is intended for scientists and engineers working on fusion R&D, as well as private sector companies working in fusion energy development areas.

Technology readiness levels (TRLs) provide a standardized and objective method for evaluating the maturity of different technologies and their different components, making it easier for all stakeholders to understand and use. By using TRLs in specific technology programme planning, everyone from government and research organizations to private sector developers, end-users, and the supply chain can benefit from a consistent and transparent evaluation process. This publication addresses the growing need for the use of TRLs in fusion programmes, and it is expected that their use will continue to increase in the future. This publication is intended for technologists, researchers, university professors and students, regulatory experts, nuclear engineers, and nuclear fusion plant planners.

The URAM-2023 Proceedings cover a range of relevant topics in the uranium production cycle from uranium exploration, through mining, milling, processing, and decommissioning and remediation of uranium production cycle facilities. This publication provides a summary of the symposium including: the opening addresses; the essay contest for students and early career professionals; 10 tracks from the technical sessions; 2 panel sessions; the closing addresses; conference secretariat and programme committee, and a list of the papers and posters. The intended audience includes exploration and mining geologists, engineers, operators, regulators, fuel cycle specialists, government officials, researchers and students.

This publication covers two main aspects of safety against external events including the site hazard assessment and the robustness of the installation against external hazards. This publication provides practical guidance and information for the development of the technology-neutral safety framework for assessing the applicability of site evaluation requirements considering site-installation interactions and taking into account the innovative safety features of the advanced reactors. A methodology is provided for an overall optimization of safety measures against external hazards, including the use of a risk-informed approach, supporting the effective and balanced implementation of the defence in depth concept. This methodology covers the application of grading that considers the safety features of the nuclear installation, allowing for a reduced implementation time/cost while ensuring robustness of the installation for applicable hazards. This publication is useful for both new and existing nuclear installations and is intended to be used by regulatory bodies, designers, operating organizations, vendors, research institutes, and technical support organizations working in the area of nuclear safety.

The International Atomic Energy Agency (IAEA) established a Coordinated Research Project (CRP) in 2013 on “Sodium properties and safe operation of experimental facilities in support of the development and deployment of sodium cooled fast reactors” (NAPRO) in order to promote an efficient collaboration between organizations involved in sodium cooled fast reactor (SFR) programmes at the national and international levels. This research programme was carried out from 2013 to 2018. Eleven organizations representing ten IAEA Member States participated in the NAPRO CRP while eight organizations contributed to the drafting of this handbook. The present publication is the technical report of the NAPRO project focusing on the collection of heat transfer and pressure drop (friction factor) correlations for sodium cooled systems.
