Date and time

Register here →


A major public event (MPE) is a planned national or international event, classified by the State as ‘major’, requiring implementation of a security plan and the preparation of an Emergency Response Plan. The organization of an MPE in which a large number of people congregate, such as a sporting contest or high-level political meeting (which could include high ranking State authorities), presents complex security challenges for the host State.

MPEs draw public interest and receive media attention. This makes them attractive venues for demonstrations, protests, violence, or any other action that can be used to draw attention to a cause. One particular area of concern for States is the potential for organizations to use these events as a stage for criminal acts and acts of terrorism, including those involving nuclear or other radioactive material.

IAEA Nuclear Security Series No. 18, Implementing Guide on Nuclear Security Systems and Measures for Major Public Events (NSS No. 18), published in 2012, provides an overview of, and guidance for designing and implementing nuclear security systems and measures for MPEs.

This webinar is the third in a series of three webinars on the topic of major public events. The other webinars in the series are:

  • Webinar on Nuclear Security Preliminary Arrangements and Pre-event Preventive Measures for Major Public Events, 26 April 2021, 13:30
  • Webinar on Nuclear Security Detection Measures and Assessments of Alerts and/or Alarms at Major Public Events, 27 April 2021, 13:30


The webinar will introduce response measures, including nuclear security specific measures, for MPEs. The first part will give an overview of these response measures in accordance with Section 6 of NSS No. 18 and the second part will provide a summary of the IAEA support programme for States on prevention of and response to nuclear security events during an MPE.

In addition, this webinar will introduce the IAEA’s guidance on arrangements for response in the event of a nuclear or radiological emergency, irrespective of the cause, during an MPE, as well as an overview of the assistance offered by the IAEA in emergency preparedness and response, to support national preparedness for MPEs and response in case of an emergency at an MPE.

Target Audience

This webinar is aimed at those working at national policy, strategic and planning or decision-making level, senior level nuclear regulators, command level representatives of law enforcement agencies and/or military, organizations involved in emergency preparedness and response, and other organizations involved in the national nuclear security regime. It is open to officials and nuclear security professionals from the above-mentioned organizations in Member States.
