This Safety Guide will aid regulatory bodies and users of radioactive material. It provides the relevant requirements as detailed in IAEA Safety Standards Series No. SSR-6 (Rev. 1) as applicable to the type of radioactive material, package or shipment. Once a consignor has properly classified the radioactive material to be shipped (following the recommendations provided in this Safety Guide), the appropriate UN number can be assigned and the paragraph numbers of specific requirements for shipment can be found in the corresponding schedule. This publication supersedes IAEA Safety Standards Series No. SSG-33, issued in 2015.

This Safety Guide provides recommendations on the design of nuclear installations for protection against the effects of external events (excluding earthquakes), meeting the applicable safety requirements established in relation to the design aspects of nuclear installations subjected to external events. It provides methods and procedures for defining an appropriate design for a nuclear installation, based on the site hazard evaluation and the layout of the installation. The aim is to provide design guidance, in particular for the protection of structures, systems and components important to safety against design basis external events. The guide also provides recommendations on the selection of beyond design basis external events, in order to check and verify safety margins.

This publication describes the practices and challenges related to risk aggregation for various hazards, various operational states, and considering all sources of potential radioactive releases at a nuclear installation site. It provides a methodology and technical basis for risk aggregation and describes the good practices and practical examples of risk aggregation developed by IAEA Member States. The description of practices is supplemented by the detailed discussion on risk communication and use of aggregated risk results to support decision making processes.

Engaging with stakeholders is an essential part of any complete nuclear programme. Involving stakeholders in decision making processes, even those stakeholder groups that do not have a direct role in making those decisions, can enhance public confidence in the application of nuclear science and technology and strengthen communication among the key organizations in a nuclear programme. This publication provides theoretical and practical guidance on the development and implementation of stakeholder engagement programmes and activities. The key principles of stakeholder engagement are identified in it. It also includes tools such as templates to help establish a stakeholder engagement programme and identify associated activities, including tools for stakeholder analysis. The guidance provided can be further developed and adjusted to each specific type of facility, moment in its life cycle, and/or the group of stakeholders with which to engage. The publication demonstrates the importance of stakeholder engagement throughout the life cycle of all nuclear facilities, including operating and new reactors, all aspects of the nuclear fuel cycle, from uranium mining to spent fuel and radioactive waste management, decommissioning, and non-power applications.

As part of the Action Plan on Nuclear Safety, the IAEA led the International Project on Managing the Decommissioning and Remediation of Damaged Nuclear Facilities (DAROD Project). The DAROD Project focuses on providing practical guidance for the decommissioning and remediation of accident damaged nuclear facilities based on case studies of actual damaged facilities and lessons learned. This publication summarizes the outcomes of the DAROD Project. It is intended for regulatory bodies, operating organizations, technical support organizations and governmental officials who are involved in the decommissioning and remediation of nuclear facilities damaged after an accident or owing to a legacy deterioration.

This publication was produced as part of the IAEA's Modelling and Data for Radiological Impact Assessments (MODARIA I and MODARIA II) programmes. It summarizes the activities of the Working Groups that considered the application of modelling to estimate radiation exposure of wildlife, and the effects of such exposure on wildlife populations. The fitness for purpose of available models and tools for estimating wildlife exposures was assessed. On the basis of the evaluations carried out, a number of models and tools are proposed for use by assessors and it can be concluded that the commonly used models are generally fit for purpose for screening level assessments. Modelling approaches for estimating population dynamics and radiation dose effects on populations of wildlife are also addressed.
