Working Together to Enhance Cooperation
Proceedings of an International Conference Held in The Hague, Netherlands, 4–7 November 2019
Proceedings Series ¦ English ¦ STI/PUB/2034 ¦ 52 pages ¦ Date published: 2022

Arising from the fifth in a series of international conferences on effective nuclear and radiation regulatory systems, this publication includes the opening addresses, a summary of the conference, and the conference President’s summary and conclusions. The participants’ presentations and posters from the conference are available as part of the online publication.

Ongoing challenges, such as capacity building for regulatory infrastructure, knowledge management, and safety and security culture are addressed. Emerging issues, such as those associated with new technologies and those related to ageing nuclear power plants and the back-fitting of current safety measures to existing nuclear power plants, and decommissioning and waste management, are considered, as is the threat posed by counterfeit and fraudulent items. An important concept throughout is the interface between safety and security. The objective of the publication is to share regulatory experiences related to improving the effectiveness of nuclear and radiation regulatory systems, addressing the international framework for the safety and security of nuclear and other radioactive material. A key message is that international cooperation to address regulatory challenges improves regulatory effectiveness worldwide.

Management of Disused Radioactive Lightning Conductors and Their Associated Radioactive Sources
IAEA Nuclear Energy Series No. NW-T-1.15 ¦ English STI/PUB/2025 ¦ 90 pages ¦ 70 figures ¦ Date published: 2022

It was formerly hypothesized that placing a radioactive source near the end of a lightning conductor would improve the likelihood that lightning would strike the conductor. It is estimated that hundreds of thousands of these radioactive lightning conductors (RLCs) were installed worldwide. However, no convincing scientific evidence has been produced to demonstrate increased efficacy and the use of RLCs does not comply with the justification principle established in the International Basic Safety Standards.

Therefore, most countries have recognized the need to stop installing RLCs and to remove existing devices from the public domain. This publication summarizes all technical and organizational aspects related to the recovery and dismantling of RLCs as well as the safe management of the associated disused radioactive sources. The report describes the general arrangement, highlights the quality management components, identifies the staffing requirements and covers certain areas vital for the preparation for dismantling and source conditioning operations. Relevant information is provided on the various models of radioactive lightning conductors and how their design features influence the dismantling and source recovery operations. The publication also incorporates the most recent experience on various concluded projects in several Member States and captures the lessons learned.

Copper-64 Radiopharmaceuticals: Production, Quality Control and Clinical Applications
IAEA Radioisotopes and Radiopharmaceuticals Series No. 7 ¦ English STI/PUB/1961 ¦ 125 pages ¦ 55 figures ¦ Date published: 2022

Positron emission tomography (PET) is an important clinical tool, and with its longer half-life, copper-64 has several unique attributes that make it a multi-purpose radionuclide with many potential applications. Additionally, copper as a trace element plays a pivotal role in several human metabolic and pathologic diseases and is involved in malignant cells biochemistry pathways.

This offers the opportunity for scientists to explore the theranostic capabilities of copper-64. This current publication, arising from an IAEA Coordinated Research Project, describes the biochemical and radiopharmaceutical aspects of copper-64, and its clinical applications, with specific guidelines and methods for the production of copper-64 chloride, peptide and monoclonal antibody radiopharmaceuticals. It is expected to be of use to all professionals involved in the field by specifying ideal production, formulation and quality control methods.

Human and Organisational Performance in Nuclear Installations
NEA No. 7579. Nuclear Energy Agency, OECD, 2022. 48 p.

This report from the NEA Working Group on Human and Organisational Performance establishes a common understanding around the terms human performance (HP), organisational performance (OP), and human and organisational factors (HOF) through a simple model. The model presented illustrates the strong inter-relationship between the terms. It shows that HP includes both human activities and the results of these activities.

HOF are the factors which have influence on HP in a positive or adverse manner in a given situation. They can be categorised as human-, technology- and organisation-related factors which are themselves under continuous interaction with each other. The report highlights the need for all managers to develop an understanding that the continuous application of a systemic approach is required to establish and sustain an effective management system and to foster safety culture.

IAEA Safeguards Glossary
International Nuclear Verification Series No. 3 (Rev. 1) ¦ STI/PUB/2003 ¦ English ¦ 300 pages ¦ Date published: 2022

Since the last edition of the IAEA Safeguards Glossary in 2001, IAEA safeguards implementation has continued to evolve, with a greater emphasis on 'State as a whole' considerations in the development of State level safeguards approaches, and reflecting a myriad of technological advancements. This new edition reflects these developments and represents terms that are either specific and unique to IAEA safeguards, or those that may be used in other domains, but which have a specific meaning or application relevant to IAEA safeguards.

New terms that have come into common use over the past two decades have also been introduced. Each term includes a definition, and where applicable, further explanation or examples. Each section addresses a specific subject area relevant to IAEA safeguards, and the terms are arranged in relation to the subject area. Within each definition, terms that are defined elsewhere in the Glossary are italicized and an index referring to the term numbers has been provided for ease of reference. The terms have been translated into the official languages of the IAEA, as well as into German and Japanese.
