As stakeholder engagement is a recognized strategic element throughout the entire lifespan of nuclear facilities, the objective of this publication is to highlight the key principles of stakeholder engagement and to provide a practical guide for developing and implementing stakeholder engagement programmes. This publication provides theoretical and practical guidance on the development and implementation of stakeholder engagement programmes and activities.

It also includes tools such as templates to help establish a stakeholder engagement programme and identify associated activities, including tools for stakeholder analysis (behaviours, motivation and values). As such, it provides basic guidance which 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.ng stakeholder engagement programmes.

Risk Aggregation for Nuclear Installations
IAEA TECDOC No. 1983 ¦ IAEA-TECDOC-1983 ¦ 140 pages ¦ 53 figures ¦ Date published: 2021

The objective of this publication is to describe the practices and challenges in Member States related to risk aggregation for various hazards, various operational states, and taking into account all sources of potential radioactive releases at the nuclear installation site. This publication provides a methodology and technical basis on risk aggregation and identifies the good practices available in IAEA Member States.

Requirements for risk aggregation in the national legal and regulatory framework differ among Member States. The specifics of how risk aggregation is done in different Member States would be impacted by different requirements, e.g. safety goals established for specific risk metrics. Therefore, the information provided in this publication could be used by multiple stakeholders (regulatory body, utilities, public) in different regulatory contexts that will drive different requirements to perform aggregation of various risk contributors for nuclear installations.
