IAEA's Incident and Emergency System

The Agency’s roles in response to nuclear and radiological incidents or emergencies are:

  • Notification and official information exchange
  • Assessment of potential emergency consequences and prognosis of possible emergency progression
  • Provision of public information
  • Provision of assistance on request
  • Coordination of inter-agency response

The Secretariat fulfils its roles through the Agency’s Incident and Emergency System (IES). The Incident and Emergency Centre (IEC) serves as the Agency's focal point for emergency preparedness and response and as custodian of the IES.

Irrespective of the cause of a nuclear or radiological incident or emergency, the Secretariat needs to be prepared to respond to any situation that may have actual or potential radiological consequences to health, property or the environment. The Secretariat relies on its competent, experienced and trained personnel to respond timely and effectively within the Agency’s response roles.

Under the IES the following specialists are on-call on a 24/7 basis:

  • Emergency Response Manager
  • Public Information Officer
  • Radiation Safety Specialist
  • Nuclear Installation Safety Specialist
  • Nuclear Security Specialist
  • External Event Specialist
  • Logistics Support Officer


Operational arrangements of the IAEA in EPR

The Agency has developed publications that:

  • Describe communication arrangements between the Secretariat, States' Parties', Member States and international organizations and describe functions under the Convention on Early Notification of a Nuclear Accident:
    Operations Manual for Incident and Emergency Communication (EPR-IEComm).
    All States should follow the indications given in EPR–IEComm and designate official Contact Points for the purpose of international exchange of information concerning nuclear or radiological incidents or emergencies.

  • Support the provision of international assistance in nuclear or radiological incidents or emergencies (upon request) and describe functions under the Convention on Assistance in Case of Nuclear Accident or Radiological Emergency: IAEA Response and Assistance Network (EPR-RANET). All States should be knowledgeable about the process to request international assistance and the need to designate official Contact Points for the purpose of requesting for and provision of assistance concerning nuclear or radiological incidents or emergencies

  • Describe the framework for the inter-agency response coordination: Joint Radiation Emergency Management Plan of the International Organizations (EPR-JPLAN)



  • Define the Secretariat’s response to a nuclear or radiological incident or emergency within the Agency’s IES – Response Plan for Incidents and Emergencies (REPLIE). This is a restricted document published for official use only


Event Reporting and Information Sharing

The Secretariat has established the IAEA Unified System for Information Exchange in Incidents and Emergencies (USIE) as the IAEA web portal for official Contact Points designated by States' Parties' to the Early Notification and Assistance Conventions and by IAEA Member States to exchange urgent information during incidents and emergencies, and for officially nominated INES National Officers to share information on events rated using the International Nuclear and Radiological Event Scale (INES).

USIE is structured in accordance with the reporting and information sharing arrangements described in EPR IEComm.

USIE is not a public website, however, media and the public are able to read and subscribe to information on events made available by the aforementioned bodies on the NEWS website, a public website hosted by the IAEA.

NEWS is a read-only website with no reporting functionality. NEWS is populated with information obtained from the USIE website.
