"This publication provides recommendations to a State for the nuclear security of nuclear or other radioactive material that has been reported as being out of regulatory control, as well as for material that is lost, missing or stolen but has not been reported as such, or has been otherwise discovered. It includes recommendations for the detection and assessment of alarms and alerts and for a graded response to criminal or unauthorized acts with nuclear security implications involving nuclear or other radioactive material out of regulatory control. The recommended actions cover the confirmation of a credible threat, assessment and interdiction of an attempted act and response to a nuclear security event."--P. [4] of cover.

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 security systems and measures within a State, such as personnel from the Ministry of Interior, Law Enforcement Agencies, Health Authorities, National Regulators, Emergency Response, and National Security Organizations.

The Global Nuclear Detection Architecture (GNDA) is described as a worldwide network of sensors, telecommunications, and personnel, with the supporting information exchanges, programs, and protocols that serve to detect, analyze, and report on nuclear and radiological materials that are out of regulatory control. The Domestic Nuclear Detection Office (DNDO), an office within the Department of Homeland Security (DHS), coordinates the development of the GNDA with its federal partners. Performance Metrics for the Global Nuclear Detection Architecture considers how to develop performance measures and quantitative metrics that can be used to evaluate the overall effectiveness and report on progress toward meeting the goals of the GNDA. According to this report, two critical components are needed to evaluate the effectiveness of the GNDA: a new strategic plan with outcome-based metrics and an analysis framework to enable assessment of outcome-based metrics. The GNDA is a complex system of systems meant to deter and detect attempts to unlawfully transport radiological or nuclear material. The recommendations of Performance Metrics for the Performance Metrics for the Global Nuclear Detection Architecture may be used to improve the GNDA strategic plan and the reporting of progress toward meeting its goals during subsequent review cycles.

Nuclear security culture is an important component of an effective nuclear security regime, as it serves as a tool to improve the performance of the human component at nuclear facilities and organizations to counter both insider and outsider threats. Security culture connotes not only the technical proficiency of the people but also their awareness of security risks and motivation to follow established procedures, comply with regulations and take the initiative when unforeseen circumstances arise. A workforce made up of individuals who are vigilant, who question irregularities, execute their work diligently and exhibit high standards of personal and collective behaviour is able to achieve effective nuclear security. Building upon this understanding of the importance of a strong nuclear security culture, this publication provides practical guidance on how to implement a systematic nuclear security culture enhancement programme.

The IAEA Safety Glossary defines and explains technical terms used in the IAEA Safety Standards and other safety related IAEA publications, and provides information on their usage. The 2018 Edition of the IAEA Safety Glossary is a new edition of the IAEA Safety Glossary, originally issued in 2007. It has been revised and updated to take into account new terminology and usage in safety standards issued between 2007 and 2018. The revisions and updates reflect developments in the technical areas of application of the safety standards and changes in regulatory approaches in Member States.

This publication elaborates upon the recommendations given in IAEA Nuclear Security Series No. 15, Nuclear Security Recommendations on Nuclear and Other Radioactive Material out of Regulatory Control, in relation to preventative measures. It serves as guidance for Member States interested in strengthening their nuclear security regime as it relates to nuclear and other radioactive material out of regulatory control and in improving their capabilities. The publication covers the following indicative elements: general considerations for preventive measures; deterrence measures, including deterrence by punishment and deterrence by denial; information security; promotion of nuclear security culture; and measures for addressing the insider threat, including measures to promote the trustworthiness of personnel. The last section of the publication provides guidance on international cooperation and assistance to strengthen preventive measures.
