Global Nuclear Emergency Preparedness Exercise ConvEx-3 (2025) – Overview and Importance

The International Atomic Energy Agency (IAEA) and Romania are conducting ConvEx-3 (2025) to test global readiness for nuclear or radiological emergencies. The exercise aims to evaluate international coordination in response to cross-border incidents. It will simulate real-time decision-making, emergency communication, and international cooperation.

Historical Context

Romania previously hosted the ConvEx-3 exercise in 2005, demonstrating its continued dedication to nuclear safety. The Cernavodă Nuclear Power Plant, situated near the Black Sea, is Romania’s sole nuclear facility.

Participants and Coordination

• Over 75 countries and 10 international organisations are partaking in ConvEx-3.
• Participants will engage national emergency centres and collaborate with the IAEA’s Incident and Emergency Centre (IEC).
• The exercise will leverage platforms like the Unified System for Information Exchange (USIE) and the International Radiation Monitoring System (IRMIS).

Emergency Scenarios and Actions

• The 36-hour exercise will involve simulated evacuations, iodine distribution, and public outreach.
• Focus will be on managing food and trade restrictions based on radiological assessments.

Conventions and Frameworks

• ConvEx exercises follow the Early Notification Convention and the Assistance Convention, guiding international collaboration during nuclear emergencies.
• ConvEx exercises are divided into three complexity levels, with ConvEx-3 being the most comprehensive.

Role of International Organisations

The Inter-Agency Committee on Radiological and Nuclear Emergencies (IACRNE) oversees ConvEx-3 coordination. Member organisations like the World Health Organization and INTERPOL ensure a comprehensive approach to nuclear emergency preparedness.

Importance of International Cooperation

ConvEx-3 underscores the critical need for global collaboration in nuclear safety. With the expansion of nuclear technology, adherence to strong safety standards and constant vigilance are paramount. Working together is essential to safeguarding people and the environment.
