International Workshop on the INEX-5 Exercises on Notification, Communication and Interfaces Related to Catastrophic Events Involving Radiation or Radiological Materials

    24-25 October 2017

    Hosted by the OECD Nuclear Energy Agency
    Boulogne-Billancourt, France


    Since 1993, the NEA has been organising the International Nuclear Emergency Exercise (INEX) series. The experiences and lessons learnt from these exercises have provided a substantial basis for the development of subsequent strategies and recommendations for improving emergency management systems nationally and internationally. Between September 2015 and October 2016, twenty-two1 countries have conducted INEX-5 on notification, communication and interfaces related to catastrophic events involving radiation or radiological materials (INEX-5). Each participating country has performed its own assessment of the exercise using the standard INEX-5 evaluation questionnaire with the intent to share, as appropriate, its experience internationally. The key results and lessons learnt were presented by 18 countries during a devoted topical session of the 41st Meeting of the Working Party on Nuclear Emergency Matters (WPNEM). On that occasion also a preliminary analysis of the questionnaires was presented by the NEA. The need for further analysis and exchange, especially on topics such as international co-ordination and communication, prompted the Working Party to organise a workshop tackling some of the key issues of this exercise.


    The main objectives of INEX-5 are:

    • to allow participating countries to identify elements for improving their arrangements for notification, communication and interfaces related to catastrophic events involving radiation or radiological materials
    • to exchange experience with other countries that have conducted and evaluated an INEX-5 exercise and other relevant international actors.


    The workshop will be held over two days as a series of plenary sessions.  It will also include breakout discussions in smaller groups to concentrate on the more detailed discussions of the workshop objectives and a breakout session in which participants will be asked to conduct a simple exercise. Preparatory work will be sent to participants in due course.

    The working language of the workshop will be English.


    The workshop programme will mainly focus on international communication and co-ordination, considering a broad range of issues including:

    • approaches and mechanisms for discussing and co-ordinating protective action decisions, particularly among neighbouring countries
    • use of real-time communications platforms
    • adequacy of national arrangements and resources to respond to requests for information
    • different countermeasure approaches
    • intermediate- and long-term aspects
    • organisation of regional exercises.

    Target audience

    This workshop is for radiological protection, emergency preparedness experts and specialists looking for approaches to more efficiently and effectively share emergency management information, and improve co-ordination of protective action decisions.

    Whilst the workshop will be based on INEX-5 exercise outcomes, there is no requirement to have played in or held an INEX-5 exercise, or to have a nuclear power programme.


    Please note that participation is limited to approximately 100 people. There is no registration fee, but pre-registration is required.

    Please register using the online form (registration instructions). The registration deadline is 6 October 2017.

    WPNEM delegates and participants to the WPNEM-42 meeting taking place on 26-27 October can also register via their national delegations.
